The invention in General relates to systems orientation and exchange of information (communication systems), and more particularly to a system and method for detecting input effects on the interacting structural element and signal transmission, mainly corresponding to the detected input effects, using the modulated electromagnetic carrier (electromagnetic waves).

The proposed system and method can be used in various applications. One example of a suitable application of the proposed system and method is used in conjunction with interacting a fluid suspension element, such as a pneumatic spring of the vehicle. The proposed system and method will be described hereinafter in more detail with particular reference to use in conjunction with a fluid suspension element. However, it should be borne in mind that the proposed system and method have wider application and therefore their use is not limited to this particular example.

Many well-known and widely used devices are already used to measure or determine otherwise the data associated with the input impacts on interacting structural element and/or its parameters. Such devices include,for example, ultrasonic height sensors, accelerometers, temperature sensors or thermocouples and/or pressure switch. However, such devices suffer from various disadvantages, which can, in certain circumstances, it is undesirable to limit their use and application. These disadvantages are particularly noticeable in some applications, for example, using the device with relative movement between the two components. This is especially true for the case when one component is stationary component and the other component moves relative to it.

One example of such a layout can be found in the suspension system of the vehicle. In this example, the element chassis or body panel consider the stationary component and the supporting wheel structure acts as a movable component. It is often desirable to install devices to measure or determine the parameters of the suspension system and/or its components rather on the stationary component, and not on the movable component. This allows you to have more mounting options and often simplifies the installation of measuring devices on the vehicle. In addition, the fastening device for measuring or determining the parameters on the stationary component makes it easier to hold and clamp the wire switching-mode power is Tania and signal wires on the frame or body of the vehicle.

In light of the described and other possible reasons usually avoid moving device for measuring or determining the parameters for the elements of the suspension system, which move relative to a stationary component, if the only other alternative solutions do not seem undesirable or impossible for other reasons. In such exceptional cases, the measuring device is installed on the movable component and wire docked along the rolling component using unloading mechanical stresses or other suitable device, formed or provided between the movable and stationary components. One example of such application is the determination of the instantaneous acceleration of the rolling component mainly in real-time. Such instantaneous acceleration is measured in order to adjust another component, such as a shock absorber, to compensate for the acceleration.

Despite the fact that the acceleration can be measured in different ways using different devices and/or calculations, using the accelerometer allows you to get accurate data, or other output signals mainly in real-time. In addition, accelerometers are compact, relatively inexpensive and usually chiefly the m way more durable. Therefore, the use of the accelerometer is often preferable to measure the acceleration of the wheel or suspension component of the vehicle. However, the known accelerometers typically have one or more conductors of the supply sensor and wires for transmitting signals and/or data. These wires should be on the frame or body of the vehicle to the accelerometer, and at least one part of the wire is subjected to bending movements between them, when the components move relative to each other. These repetitive motion of bending can lead to breakages of the wire due to his tiredness and/or other problems. Moreover, when this wire is often subjected to undesirable influences the environment and pollutants, such as dirt, water and salt. It may be undesirable to cause deterioration of the wire and/or isolation, which may accelerate the onset of fatigue of the wire and quickly lead to breakages of the wire. In addition, the wire is subjected to impacts from rocks on the road that could damage the cord and/or its connection to the sensor.

Thus, it is desirable to create a device, system and method for determining orientation and information sharing, which allow to eliminate these and other disadvantages.

The invention

Features the system determine the orientation and exchange of information for use in interactive constructive element, experiencing external influence, and this system includes a transceiver capable of transmitting on the radio electromagnetic oscillation, and the defendant is located at some distance from the transceiver. The sensor is fixed on the interacting structural elements and has a relationship with the defendant. The sensor may produce an output signal carrying information about external influence. The defendant receives the electromagnetic oscillation and the output signal of the sensor and generates a modulated electromagnetic oscillations depending on (connected with) the output signal of the sensor.

Proposed system for determining orientation and exchange of information for use in interacting first and second structural elements, which are located at some distance from each other, interacting with the second structural element undergoes external influence, while this system contains the transceiver, mounted (installed) on the interacting first structural element and capable of transmitting on the radio electromagnetic vibration. The defendant has the communicating the second structural element and receives the electromagnetic oscillation. The sensor is installed on interacting the second structural element and has a relationship with the defendant. Sensor g is nerium output signal depending on external influences. The responder receives the output signal of the sensor and modulates the electromagnetic vibration according to at least one parameter selected from the group comprising the output signal of the sensor and the distance.

Proposed method of providing the input level of the external input action, acting on the interacting structural element, and the method involves the use of a transceiver that can transmit on the radio electromagnetic vibration. The method also provides for the use of the defendant, mounted on interacting structural elements and located at some distance from the transceiver, and the use of a sensor mounted on the interacting structural elements in the vicinity of the defendant. The sensor may produce an output signal corresponding to the input level of external influence. The method further includes supplying power to the transceiver and the radio electromagnetic waves, and the generation of the output signal of the sensor. The method also provides for the creation of modulation of electromagnetic waves depending on the output signal of the sensor and detecting the input level of the external action on the basis of the modulation.

Proposed site air springs in choosing the accordance with the proposed new concept, which contains the first end element, the second limit element is located at a distance from the first end element and undergoes external impact, and a flexible wall secured between the first and second end elements. The transceiver is mounted on the first end element and can transmit on the radio electromagnetic vibration. The defendant is installed on the second end element and can be electromagnetic vibration. The sensor is mounted on the second end element and has a relationship with the defendant. The sensor can measure the external input stimulus to the second end element and to produce a corresponding output signal of the sensor. The responder receives the sensor output signal and generates a modulated electromagnetic oscillations in response to the sensor output.

Proposed communication system in accordance with the proposed new concept, designed for the suspension system of a vehicle having a first component of the vehicle and the second component of the vehicle undergoing input stimulus to the suspension, and the communication system includes a transceiver mounted on the first component of the vehicle and transmit a radio electromagnetic vibration. The defendant is mounted on the second component of transport is the main means, at some distance from the transceiver, and has a connection with him. The sensor is mounted on the second component of the vehicle and can detect input stimulus to the suspension, and the sensor has a relationship with the defendant and can produce the sensor output corresponding to the input effects on the suspension. The Respondent may accept the output signal from the sensor and to generate a modulated electromagnetic oscillations in response to the reception of this signal.

We propose a method of determining the setting of the suspension component of the vehicle in accordance with the proposed new concept, which involves the use of a transceiver, which allows to transmit radio electromagnetic vibration, and the use of the defendant that is installed on the suspension element of the vehicle and located at some distance from the transceiver. The method also involves the use of a sensor mounted on the suspension element of the vehicle close to the defendant, and the sensor may produce an output signal of the sensor corresponding to the parameter element of the suspension of the vehicle. The method also includes supplying power to the transceiver and the radio electromagnetic waves. The method further provides expression is otcu output signal of the sensor and the creation of modulation of electromagnetic waves in response to the output signal of the sensor. The method further provides for determining a parameter value of the suspension element of the vehicle on the basis of the modulation.

Detailed description of the invention

Let us now turn to a more detailed consideration of the drawings are shown only to illustrate the preferred options proposed new system, device and/or method without a restrictive nature. 1 schematically shows a system specifying the distance that contains the transceiver 100, used in conjunction with the defendant TSP, which is located on a is the leg DST from the transceiver. It should be borne in mind that the defendant TSP is just a representative example of a suitable defendant, interacting with the transceiver, such as transceiver 100, and the design and operation of an exemplary variants of the appropriate respondents discussed later in more detail. The transceiver 100 is configured to transmit radio electromagnetic signal, such as, for example, electromagnetic (EM) carrier CWV, in the direction of the defendant TSP.

The transceiver 100 includes a generator 102 carrier having electrical connection with the antenna 104. The generator 102 carrier may file output electrical carrier signal at the antenna 104, which, in turn, may transmit on the radio electromagnetic bearing, such as bearing CWV, for example, the corresponding output signal generator 102 of the carrier. The detector 106 modulation also has electrical connection with the antenna 104 and configured to detect the modulation electrical characteristics along or across the antenna. The modulation detector produces an output electrical signal such as voltage or current, for example, in the respective dependent on the amplitude modulation along or across the antenna. Figure 1 shows that the detector 106 modulation produces an output analog signal which can be amplified by the amplifier 108 to send as e is about shown by the arrow 110, on the other electronic device, scheme, or system, for example, such as an electronic control unit (not shown).

Figure 1 shows the circuit 112 power supply. The power supply circuit may be formed as part of a fully integrated transceiver circuit 100 in the form of a separate schema is structurally integrated with the transceiver 100, or in the form of diagrams, completely separate from the transceiver 100. In accordance with an exemplary variant, shown in figure 1, the power supply circuit 112 is formed as part of a fully integrated transceiver. However, regardless of design, the circuit 112 power supply is made with the ability to apply appropriately standardized and regulated electrical energy from a power source (not shown) on the components of the transceiver 100. These components may include, without limitation, the generator 102 of the carrier, with cotrim power supply circuit 112 shown in figure 1, has a direct electrical connection. It should be borne in mind that the power source (not shown) may be any suitable power source AC or DC, for example, such as a battery (car or other), generator or alternator, electronic control unit or power module of the control system.

Typically, the antenna 04 transceiver 100 may transmit on the radio or otherwise output electromagnetic signal, for example, such as carrying CWV, as already mentioned here above. The antenna ANT of the defendant TSP receives a carrier that has one or more characteristics (or properties)that change with distance, which is well known to specialists in this field. The defendant is to excite or create some other way of modulation of the carrier depending on the distance between the transceiver and the defendant. In one example of such work, well-known experts in this field, the antenna 104 and ANT act as winding of the transformer with a weak link when they are touched by a carrier CWV. In this case, the instantaneous change in the electrical characteristics or properties of a single antenna initiates, or otherwise creates a corresponding change in the electrical characteristics or modulation along or across different antennas. This modulation helps to determine the distance DST between the transceiver and the defendant or, alternatively, to exchange data between themselves, as discussed in more detail below.

Alternative transceiver 200 shown in figure 2 and comprises a generator 202 carrier having electrical connection with the antenna 204. The generator carrier 202 is arranged to supply the output of the electrical carrier signal at the antenna 204, which receives the carrier signal from the generator and made the with radio electromagnetic carrier, for example, such as carrying CWV corresponding to the carrier signal from the output of the generator 202.

The detector 206 modulation also has electrical connection with the antenna 204 and is configured to detect the modulation electrical characteristics along or across the antenna. The detector 206 modulation produces an analog signal depending on the amplitude modulation along or across the antenna 204. However, instead of the analog amplifier output signal, as in the transceiver 100, the transceiver 200 includes an analog-to-digital Converter (ADC) 208, which has electrical connection with the detector modulation. Analog-to-digital Converter receives the analog signal from detector 206 modulation and converts it into a digital data stream. The flow of digital data from the Converter 208 may then be transferred in the usual way, for example, such a device as the microcontroller 210 or to another component or another system. It should be borne in mind that such device or any other system which contains the microcontroller 210 can be made as a whole with the transceiver 200, or may be part of another, separate system. For example, the processor may communicate with the data bus of the vehicle, such as a CAN bus, data bus, SAE J1, 860, or another information system transportnogo the funds.

Circuit 212 of the power supply shown in figure 2. However, it should be borne in mind that the chain 212 power supply can have different implementations or different configurations, as already mentioned here above, to submit appropriately standardized and regulated power to the circuit 200.

Generators 102 and 202 of the carrier to produce an output electrical carrier signal which can be transmitted by radio as an electromagnetic carrier using interactive antenna. In accordance with the preferred option, the output electrical signal generators 102 and 202 of the carrier is a sine wave having a mainly constant amplitude and frequency; however, it should be borne in mind that can be used with any other suitable electrical carrier signal. It should also be borne in mind that the output electrical signal generators can have any suitable voltage, for example, approximately from 50 to 100, and may have any suitable frequency, for example, from approximately 100 KHz to 30 MHz. In accordance with an exemplary variation of an electrical signal has a frequency of about 125 KHz and an amplitude of about 100, but these values may vary from one application to another, as already mentioned here above.

Circuit diagram 300 of one of variantenproduktion, for example, such as a transceiver 100, as shown in figure 3 and contains the schema generator 302 of the carrier, the antenna circuit 304, the circuit 306 detector modulation scheme and amplifier 308. It should be borne in mind that the schema generator 302 generally corresponds to the generators 102 and 202, shown respectively in figures 1 and 2, and the corresponding nodes 304, 306 and 308 correspond to the antennas 104 and 204, the detectors 106 and 206 modulation and amplifier 108. It should also be borne in mind that the analog-to-digital Converter 208 and the microcontroller 210 have the typical construction well known to specialists in this field, so that the specialists can easily electrically connect the analog-to-digital Converter 208 to the detector 206 modulation, even if not shown its electric circuit. It should also be borne in mind that in the circuit 300 is not provided by the power supply circuit corresponding to the power supply circuit 112 or 212. However, it should be borne in mind that the circuit 300 can alternatively contain a power supply circuit, even when the primary power source contains the appropriate schema processing and control, allowing you to draw a diagram 300 of the necessary electric power. Moreover, experts can easily understand that the circuit 300 may be implemented as an integrated circuit on a single substrate such as a silicon wafer, or alternatively can be brasovan from discrete components using any suitable manufacturing techniques.

As shown in figure 3, the circuit 300 contains a variety of traditional electrical components, including (but not limited to, resistors, capacitors, diodes, operational amplifiers and chokes. It should be borne in mind that these components are mainly standard design, if not otherwise stated, and may be easily purchased in the market. In addition, different parts of the circuit 300 is connected to a positive terminal of a power source (not shown) or the power supply circuit (not shown) in one or more common points. With the connection areas of the circuit 300 end arrows lead terminals 310. Similarly, different parts of the circuit 300, which are connected to a common ground end arrows lead terminals 312.

As already mentioned here above, the circuit 300 includes many of the operational amplifiers. However, it should be borne in mind that these operational amplifiers figure 3 shows schematically using traditional configuration pin conclusions. Despite the fact that these male header pins do not have positional notation, it should be borne in mind that each operational amplifier has the opposite pin pins supply voltage (SV pin conclusions), positive input pin (PI pin), negative the input pin (N1 pin) and output pin (pin). One example of a suitable operational amplifier is an operational amplifier type LM248 company Texas Instruments of Dallas, Texas.

The circuit 302 of the carrier generator includes an operational amplifier 314, resistors 316-324 and the capacitor 326. Operational amplifier 314 is SV pin pins arrows terminals 310a and a. FROM the pin connected to the voltage divider formed between arrows pin clips 310b and 312b through resistors 316 and 318. FROM pin connected to the voltage divider through resistors 320 and 322 and forms a feedback loop due to the PI pin terminal of the operational amplifier 314 connected between the resistors 320 and 322. Additionally, FROM the pin of the operational amplifier is connected to earth at the arrow of the contact clip s through resistor 324 and capacitor 326. A feedback loop is formed with pin output by connecting the NI terminal of the operational amplifier between the resistor 324 and capacitor 326.

Electrical carrier signal from pin output FROM the operational amplifier 314 is supplied to the antenna circuit 304 wire 328. The antenna circuit 304 includes a capacitor 330, which has electrical connection with the earth at the arrow of the contact clip 312d through the orifice 332, which is displayed figure 3 using the standard symbol. However, it should be borne in mind that it may be desirable adjustment or optimization of the antenna and, in such situations, can be used choke specific design, which, for example, has a square shape. In accordance with an exemplary option, the inductor 332 is a coil of wire, which has a ring shape or form loops.

Circuit 306 detection modulation has electrical connection with the antenna circuit 304 wire 334, which is connected between the condenser 330 and inductor 332. Wire 334 has an electric connection with the NI pin output of the operational amplifier 336 through the diode 338 and capacitor 340. Operational amplifier 336 is SV pin findings, coupled with arrows pin clips 310c and e. A feedback loop is formed between FROM and NI pin conclusions of the operational amplifier 336 using wire 342 is connected through a diode 344 and resistor 346. PI pin of the operational amplifier 336 is connected between the arrows pin clips 310d and 312f through resistor diode 348 and 350, respectively. The diode 350 is shown in figure 3 as a Zener diode. Additionally, the arrow terminal 312f connected to the NI pin output of the operational amplifier 336 by means of a wire 334 through a resistor 352. The arrow terminal 312g connected to Prov the DN 334 separately through a capacitor 354 and resistor 356.

Circuit 308 amplifier electrically connected to the circuit 306 modulation detection using a wire 358. Circuit 308 amplifier includes a first operational amplifier 360, and the wire 358 is connected to the PI pin to output and is connected to the wire 334 due to the connection between NI pin output of the operational amplifier 336 and capacitor 340. Operational amplifier 360 is SV pin pins arrows terminals e and 312h. A feedback loop is formed using a wire 362 connected between FROM and NI pin conclusions of the operational amplifier 360. The diode 364 is connected to the wire 362 and NI pin of the operational amplifier 360 is also connected to the arrow pin clip 312i through resistor 366 and the arrow pin clip 312j through a capacitor 368. PI pin of the second operational amplifier 370 is connected to the wire 362 through the diode 364 and NI pin of the operational amplifier 360 through the wire 372. Output connector 374 connected FROM the pin to the output of the operational amplifier 370 through an output wire 376. A feedback loop is formed using a wire 378 connected between NI pin output and wire 376 connected between pin output and the output connector 374. It should be borne in mind that the output connector 374, ka is the rule, acts as a device mates with the contact 110 connection, shown in figure 1. By itself, the connector 374 may be a connector of any suitable type and may have any suitable configuration.

The defendant 400 shown in figure 4 and includes an antenna 402, a power circuit 404 and a shunt circuit 406. As a rule, the defendant 400 is at a distance from one of the transceivers 100 or 200 and works together with them. More specifically, the antenna 402 is configured to receive electromagnetic carrier CWV, transmitted via a radio antenna transceiver. Electromagnetic carrier excites the electrical output signal along or across the antenna. This electrical output signal is fed into the power circuit 404, which accumulates an electric output signal, and periodically supplies power to the shunt circuit 406. When it is powered up, the shunt circuit produces a short circuit of the antenna 402. This causes a change in the electromagnetic properties of the antenna 402, for example, significantly reduces the inductance of the antenna. Change the electromagnetic properties of the antenna 402 causes a corresponding change along or across a corresponding antenna of the transceiver, such as transceiver 100 or 200. This change along or across a corresponding antenna of the transceiver detecting the contact associated with the detector modulation transceiver, for example, such as the detector 106 or 206 modulation.

In accordance with one exemplary variant, the antenna 402 defendant 400 includes an inductive element (not shown). It is along or across this inductive element electromagnetic carrier excites an electrical output signal which is transmitted to the power circuit 404. Electrical output signal which represents the electrical potential and/or the electric current is accumulated in the power circuit 404, which, in response, transmits a pulse of electric energy in the shunt circuit 406, after a certain specified amount of electric power accumulated in the power circuit. The pulse of electrical energy causes the shunt circuit 406 to create electrical short circuit the inductive antenna element 402. Short circuit inductive element reduces its inductance to zero. Experts can easily understand that this will cause a corresponding change along or across the inductive antenna element in the United transceiver, as these two elements act as a transformer with a weak link. This corresponding change monitors (measures) the modulation detector. This excited field modulation (IFM) is indicated generally sinusoidal wave IFM figure 4.

Electric circuit the Hema 500 one variant of the defendant 400 shown in figure 5 and contains the antenna circuit 502, power circuit 504 and a shunt circuit 506. Typically, the antenna circuit 502 corresponds to the antenna 402, shown in figure 4. Similarly, the power circuit 504 corresponds circuit 404, and a shunt circuit 506 corresponds to the circuit 406. As already mentioned here above, the circuit 500 includes many traditional electrical components, including (but not limited to, resistors, capacitors, diodes, operational amplifiers, and an inductor (choke). It should be borne in mind that these components are essentially standard design, unless specifically stated otherwise, and can be easily purchased. In addition, the circuit 500 may be implemented as an integrated circuit on a single substrate such as a silicon wafer, or alternatively, may be assembled from discrete components using any suitable manufacturing techniques. In addition, different parts of the circuit 500 is connected to the common ground, which shows the contact clip 508 in the form of arrows.

The antenna circuit 502 includes a capacitor 510 and the throttle 512 connected in parallel between wires 514 and 516, the latter of which is connected to the arrow pin clip a near the orifice 512. The choke shown in figure 5 using the standard symbol. However, it should be borne in mind that it may be desirable adjustment or optimization ante the us, carried out, for example, in conjunction with inductor 332 antenna circuit 304. In such situations, can be used choke specific design, which is a coil of wire, which has, for example, a square shape, circular shape or form loops.

Power circuit 504 is connected to the antenna circuit 502 through wires 514 and 516. Diode resistor 518 and 520 are connected in series with the wire 514. Transistor 522 and capacitor 524 is connected in parallel between wires 514 and 516. The collector output s transistor 522 is connected to the wire 514, and the emitter output a transistor is connected to the wire 516. Wire 526 connects the base output 522b of the transistor 522 to the wire 514 through the diode 528. In accordance with an exemplary option, the diode 518 is a diode of a Schottky, and the transistor 522 is a standard n-p-n transistor, which are well known to specialists in this field.

Shunt circuit 506 is connected to the power circuit 504 via wires 530, which goes to the collector output s. Wire 530 is connected to the upper point of the voltage divider formed by resistors 532 and 534, which are included between the wire 530 and is shown by an arrow by the contact clip 508b. Shunt circuit also includes an operational amplifier 536. One SV pin of the operational amplifier is connected to the wire 530 through wire 58, and the other SV pin is connected to the arrow contact terminal 508. Wire 540 connects the midpoint between resistors 532 and 534 with PI pin output of the operational amplifier through resistor 536 542. A feedback loop is formed between and PI pin conclusions of the operational amplifier 536 using wire 544, which forms a connection through a resistor 546. FROM the pin of the operational amplifier 536 is also connected to the arrow pin clip 508d using wire 548 through a resistor 550 and capacitor 552. NI pin of the operational amplifier is connected through wire 554 to the middle point between the resistor 550 and capacitor 552. Relay 556 is connected between pin output of the operational amplifier 536 and wires 514 and 516 near the capacitor 510, connected in parallel to the inductor 512. It should be borne in mind that instead of relay 556 can be used in a switching device of any suitable type, such as field-effect transistor.

Antenna 502 of the defendant is entered in the RF field of the transceiver, which generates a voltage (across) the antenna 502. This voltage passes through the diode 518 in circuit 504 power source (power circuit), which regulates the voltage on the wire 530 for proper operation of the shunt circuit 506. Resistors 532 and 534 divide the incoming wire 530 nab agenie for comparison with the voltage on the wire 554, connected to the NI pin output. Resistor 550 and capacitor 552 control the slew rate of the voltage on the wire 554 connected to the NI pin output. As the voltage on the wire 554 exceeds the voltage on the PI pin output associated with the mid-point between the resistors 546 and 542, there is an output signal FROM the pin output of the operational amplifier 536. This causes the relay 556 (or other suitable devices, such as field-effect transistor), which bypasses to ground the antenna 502. Bypass antenna removes the voltage from the transceiver and creates a measurable change, allowing to determine the distance.

Figure 6 shows one exemplary form of modulated electromagnetic carrier CWV with standard sinusoidal oscillation and the initial amplitude of the voltage V. the modulated Carrier in the interval DT, during which its amplitude reduced by the value of DV. Exemplary suitable range of voltage V is approximately from 50 to 150 C. the Approximate range of amplitude modulation, the mapped value of DV is approximately from 10 to 1000 mV. Amplitude modulation may be of any suitable duration, or interval DT, for example approximately from 0.1 to 5 MS. As already mentioned here above, the carrier CWV can have any of the right frequency, for example, from approximately 100 kHz to 14 MHz. Such modulation specialists usually referred to as modulated scattering in reflection, and it can be used to arrange the transfer between the Respondent and the transceiver.

One of the well known examples of the use of modulation of the scattering reflection is the use of systems, radio frequency ID (RFID). However, it should be borne in mind that proposed here a new concept differs significantly from the traditional use of RFID systems. In particular, traditional RFID systems use data that are encoded within a single tag. Tag combined with the object, and the data typically contain one or more parts that are specific to this object. Typically, RFID systems do not use to determine the distance of the tag from other system components. The main objective of these RFID systems is reading data encoded within the tag.

The approximate scheme of the sequence of operations of the method 700 shown in Fig.7 and contains the first operation 702 use of the transceiver and of the Respondent, such as, for example, the transceiver 100 or 200 and the defendant 400, which are connected with each other and are at a distance from each other. Another operation 704 provides the broadcast electromagnetic carrier, such as, for example, carrier CWV, and the Tenna transceiver to the antenna of the defendant. The next operation 706 provides for the reception of the carrier at the antenna of the defendant. Experts can easily understand that the electrical energy is excited with this along and/or across the inductor due to the impact of the received electromagnetic waves. Optional operation 708 provides for the accumulation of electrical energy, excited along and/or across the antenna of the defendant due to the impact of the adopted electromagnetic carrier. The next operation 710 provides for selective shunting the antenna of the defendant and the creation of the antenna of the transponder modulation of one or more electrical characteristics, such as short-term decrease in voltage. Further operation 712 provides for detection of the modulation of the electric characteristics along or across the antenna. The next operation 714 provides for determination of the distance between the transceiver and the Respondent based, at least in part, to modulation of the electrical characteristics in operation 712. Further operation 716 provides for the grant of a signal indicating the distance specified in operation 714.

One of the examples we offer here a new concept associated with the item 800 fluid suspension shown in Fig. More specifically, element, fluid suspension is pneumatic the Skye spring, with traditional design with a piston and a collapsed lobe. However, it should be borne in mind that the element of the fluid suspension may be an element of any suitable type, style, type and/or configuration that does not extend beyond the use here of the new concept. Element 800 fluid suspension includes a first end element, such as the top plate 802, the second limit element such as a piston 804 mounted at a distance from the first end element, and a flexible element such as a flexible sleeve 806 supported between them and forming an internal volume, such as fluid camera 808.

The transceiver 810 is mounted on the top plate 802 within the fluid chamber 808 and the defendant 812 is mounted on the piston 804 offset (distance) from the transceiver. The piston 804 has an outer peripheral wall 814, along which moves the flexible sleeve 806, and the Central inner wall 816. Shown in Fig inner wall is mainly concave or has the shape of a plate and includes an internal recess 818. Inner wall 816 has a section 820 of the side wall and the section 822 of the lower wall, which is fixed to the defendant 812. The defendant 812 can be fixed on the inner wall 816 any suitable manner, for example using the MDL or mechanical fastening means. Alternatively, the defendant 812 may be pressed into the inner wall 816, as shown by the defendant 812'. It should be borne in mind that the transceiver 810 may be any suitable transceiver, including transceivers 100 and 200. Similarly, the Respondent 812 may be any suitable Respondent, including the Respondent 400.

As soon as electromagnetic carrier CWV, transmitted by radio, will be adopted by the defendant 812, electric energy, excited along and/or across the antenna, such as antenna circuit 402 defendant 400 will be at least intermittently to supply energy to the defendant, for example, as described previously with reference to the power circuit 404. Alternatively, the electrical energy may be supplied from a battery or other suitable power source. When the defendant 812 is energized (powered), a shunt circuit, such as a shunt circuit 406 defendant 400, are periodically bypasses the antenna defendant 812, which creates a modulation of the antenna of the transceiver 810, such as antenna 104 or 204. The relationship between the antennas of the defendant and the transceiver, which has already been discussed above, the only explanation is shown in the form of sinusoidal oscillations IFM on Fig. One or more characteristics or parameters of modulation directly correspond or mA is tematicheskie associated with the distance between the Respondent and the transceiver, as is well known to experts in this field. The transceiver detects the modulation and generates a signal indicating the distance between the transceiver and the defendant. It should be borne in mind that can be used and different from the described modes of operation, which does not go beyond here a new concept.

Another alternative transceiver 900 is schematically shown in Fig.9. The transceiver 900 includes a generator 902 carrier, which has electrical connection with the antenna 904. Similarly discussed here above generators 102 and 202 of the carrier generator carrier 902 is configured to supply electrical carrier signal at the antenna, which, in turn, performs radio transmission of the corresponding carrier CWV. The detector 906 modulation electrically connected to the antenna 904, usually in front of the generator carrier 902. The detector 906 modulation similar to the detectors 106 and 206, which are discussed here above, in that the detector 906 is configured to detect the modulation of the electrical characteristics or parameters along or across the antenna. However, the detector 906 modulation differs from the detectors 106 and 206 in that the detector 906 is configured to supply a digital signal DSG corresponding modulation, along or across the antenna circuit 904, and not analog si is Nala, with characteristics such as the level of the voltage or current corresponding to the modulation level, as in the detectors 106 and 206. Digital signal DSG is supplied to the corresponding digital device, such as a processor or microcontroller 908 digital signal, which converts, decodes and/or analyzes the digital signal DSG and emits a corresponding signal indicating the distance between the transceiver and communicating with it by the defendant. The output signal from the microcontroller 908 enters located next system or device, as shown by arrow 910.

In addition, in Fig, 9 shows the circuit 912 power supply, which has electrical connection with the generator carrier 902. It should be borne in mind that, in other embodiments, the circuit 912 power supply can also bring electrical energy to other components of the transceiver 900. As already mentioned here above with reference to the circuit 112 power transceiver 100 shown in figure 1, the circuit 912 power supply may be of any suitable shape or configuration and may be performed in conjunction with other components of the transceiver 900 or separately from them. One example of a suitable transceiver is a transceiver, manufactured by Microchip Technologies, Inc. of Chandler, Arizona, product number MCRF 200.

One example of the Respondent suitable for use in conjunction with the transceiver 900, shown in figure 10 as the defendant 1000. As a rule, the defendant 1000 works in conjunction with the transceiver, such as transceiver 900, to determine the distance between them and generate an output signal indicating this distance, as has been described above. However, in the foregoing embodiments, the transceiver, such as transceiver 100 or 200, determines the distance between the two components on the basis of amplitude modulation along or across the antenna. The primary task of interacting defendant, like the defendant 400, is the initiation or creation of this modulation. In this case, the transceiver 900 and the defendant 1000 based on the proposed new concept and using discussed here above the main principles of the work of other options. However, here the defendant 1000 determines, at least partially, the distance between the two components, for example, using a digital processing device. However, digital data corresponding to the distance, and/or other data such as an identification code or an identification number will be transmitted at least from the defendant to the transceiver. This transfer of data and/or communication can be of any suitable form, including (but without limitation) the form of direct transfer of the data and transfer tirovannyh data as discussed in more detail below.

As shown in figure 10-14, this solution differs from previous versions in structure and operation, as discussed in more detail below. The defendant 1000 includes an antenna 1002, allowing to receive electromagnetic carrier CWV, for example, which may be transmitted via a radio antenna 904 transceiver 900. As has been described above, the carrier CWV excites electrical energy along and/or across the antenna 1002. Electrical energy is transmitted into the power circuit 1004 and the shaper (scaler, scaling device 1006, which have electrical connection with the antenna. Typically, the power circuit accumulates at least part of electric power and periodically supplies power to one or more components of the Respondent, as described here above.

The imaging unit 1006 is used to decrease or minimize one or more electrical characteristics (or parameters), such as a voltage or current signal from the antenna 1002 that pass through it. Driver 1006 mainly generates signal from the antenna 1002 to receive and use a digital signal processor or microcontroller 1008, which has an electric connection with the shaper and power circuit. But mainly it is the reduction or slimming the electrical signal produced so to support (proportional to) the dependence of the reduced signal from the original signal. In this case, the microcontroller 1008 can be used to determine the distance between the associated transceiver, such as transceiver 900, and the defendant 1000. As already mentioned here above, the experts will readily understand that one or more characteristics of the electromagnetic waves vary depending on the distance travelled in accordance with well-known dependencies between them.

As already mentioned here above, the power circuit 1004 periodically supplies power to one or more circuits (or components) of the Respondent. One such receiving power from the power circuit component is a microcontroller 1008, which determines the amplitude or another electrical characteristic (or parameter) of the signal output from the imaging unit 1006. This amplitude or other parameters have a direct or other mathematical relationship with the distance between the transceiver and the defendant. Thus, the microcontroller can determine the actual numeric value of the distance and then pass it back to the transceiver. Alternatively, the microcontroller can just pass the amplitude or other characteristic of the signal output from the imaging unit, without specific definitions on setitemimage numeric value of the distance. In this alternative example, once the signal from the shaper is fed back to the receiver module, the microcontroller can convert or calculate the actual numeric value of the distance.

After the microcontroller 1008 received power and the determined characteristic or parameter of the signal output from the imaging unit 1006, the microcontroller selectively activates the shunt circuit 1010 for data transmission, mainly containing data corresponding to the distance value or the output signal from the shaper, back in the United transceiver. After activation of the shunt circuit 1010 is electrically short circuits the antenna 1002, which, in turn, stimulates the modulation along or across a corresponding antenna of the transceiver, such as an antenna 904 transceiver 900. The relationship between antenna transceiver and the Respondent was considered in detail here above, and shows sinusoidal oscillations IFM figure 10.

In accordance with one exemplary variant, the signal value or the value of the actual distance is transmitted as data from the responder back to the transceiver, the microcontroller 1008, selectively exciting the shunt circuit 1010. Data transfer from the defendant to the transceiver can be made in any VI is e, for example in the form of a binary data stream, directly corresponding to the signal values or distances. Alternatively, the digital communication may be encoded, in order to minimize losses, for example, caused by interference. Can be used with a wide variety of known coding device, for example, using frequency-shift keying (FSK) and phase shift keying (PSK), which is well known to specialists in this field. The example carrier CWV, modulated using FSK, shown at 11 and includes a bearing CWV, modulated between HST high amplitude and state LST low amplitude. Modulation can be used to transfer data in any suitable way, for example, using shift FS1 8 periods corresponding to zero (0) value, and shift FS2 10 periods, the appropriate unit (1) value. In this way a stream of binary data can be transferred from the Respondent to the transceiver. The example carrier CWV, modulated using PSK, shown in Fig and also includes a bearing CWV, modulated between States HST and LST. As shown in Fig, the frequency shift of the carrier remains constant, for example, in one period, with HST, in the next period when the LST, in a subsequent period, when HST, etc. But the data can be used in phase with the vig, so two periods occur in the same condition. In accordance with one example, each phase shift PST displays zero (0) in the binary data stream. In another example, each phase shift PST displays the data changes (from 0 to 1 or from 1 to 0). However, it should be borne in mind that can be used and other suitable types of modulation and/or data transmission technology.

However, it should be borne in mind that it may be desirable adjustment or optimization of the antenna, which is carried out to improve interaction with other antenna, for example, such as an antenna 904 transceiver 900. In this case, can be used choke specific design, which is a coil of wire, which has, for example, a square shape, circular shape or form loops.

In addition, the microcontroller 1108 has an electric connection with the conductor 1120 via the imaging unit 1106, using wire 1136. The microcontroller 1108 may be of any suitable shape or configuration. One example of a suitable microcontroller is a microcontroller, manufactured by Freescale Semiconductor, Inc. of Austin, Texas, product number 68HC05L25. This microcontroller contains a processor, memory, and clock generator. Driver 1106 may also have any suitable shape or configuration.

Another approximate the option scheme 1200 sequence of operations of the method is demonstrated Fig and contains an operation 1202 use of the transceiver and of the defendant, for example, such as a transceiver 900 and the defendant 1000, which is installed at a distance from each other. Another operation 1204 provides the broadcast electromagnetic carrier from the antenna of the transceiver to the antenna of the defendant. The next operation 1206 provides for the reception of the carrier at the antenna of the defendant. Optional operation 1208 provides for the accumulation of electrical energy, excited along and/or across the antenna of the defendant.

Another operation 1210 of method 1200 involves the reduction of the electrical signal from the antenna of the defendant up to the value suitable for use in the processor or microcontroller. Another operation 1212 provides for determining a distance or a numeric value corresponding to the distance, on the basis of the reduced electric signal.

On Fig schematically shows the approximate variant of the system 1300 determine the orientation and exchange of information in accordance with the proposed new concept that contains the transceiver 1302, used in conjunction with the defendant 1304. The transceiver and the defendant are located at some distance from each other, as shown by the distance DST. The transceiver 1302 mainly similar to the transceiver 900, which is shown in figure 9 and discussed here above, and comprises a generator 1306 carrier, which has electrical connection with the antenna 1308. Generator 1306 carrier is arranged to supply the output of the electrical carrier signal at the antenna 1308, which, in turn, may transmit on the radio corresponding bearing CWV. The detector 1310 modulation electrically connected to the antenna 1308, as a rule, in front of the generator 1306 carrier. The detector 1310 modulation is configured to generate a digital signal DSG corresponding modulation along or across the antenna 1308. Digital signal DSG comes in to meet the future digital device, for example, such as a digital signal processor or microcontroller 1312, which converts, decodes and/or analyzes the digital signal DSG and emits a corresponding signal is located next system or device, as shown by the arrow 1314. As an example of a suitable transceiver can cause the transceiver type MCRF 200, which may be purchased on the company Microchip Technologies, Inc., of Chandler, Arizona.

In addition, Fig shows the circuit 1316 power supply having an electrical connection with the generator 1306 carrier. As already mentioned here above, for example, with reference to the circuit 112 power transceiver 100 shown in figure 1, the circuit 1316 power supply may be of any suitable shape or configuration and may be performed in conjunction with other components of the transceiver 1302 or separately from them.

The defendant 1304 on Fig shown when working together transceiver 1302, when he takes the carrier CWV from him, as it was already mentioned here above in the description of other options. The defendant 1304 differs from the others discussed here previously, defendants fact that there is a sensor 1318, operatively interacting with the defendant, which modulates the carrier CWV, as shown in the General form of a sinusoidal oscillation IFM and have been discussed at length here before. The defendant 1304 can modulate the carrier in CWV for the W ill of the distance DST, which is also discussed in detail here, for example, with reference to the responder 1000 shown in figure 10. Additionally or alternatively, the defendant 1304 can modulate the carrier in dependence on the output signal of the sensor 1318, as is discussed further hereinafter in more detail, and it should be borne in mind that the defendant 1304 can modulate the carrier CWV depending on the distance DST output signal of one or more sensors, such as sensor 1318, or based on a combination of distance and output signals of the sensors, if this is desirable. In addition, modulation of the carrier depending on the distance DST and/or the output signal of the sensor can be implemented on any suitable operating frequency or over any suitable period of time, during continuous or intermittent working intervals.

Alternative transceiver 1302' shown in Fig, and this transceiver is similar to the transceiver 1302, shown in Fig. At the same time similar or identical elements in the various drawings have the same reference designators, and new or modified elements have a positional notation with a dash (').

The transceiver 1302' contains the generator 1306 carrier, which is connected with the antenna 1308 to transmit radio carrier CWV. Dete is Thor 1310 modulation is associated with the antenna 1308 opposite generator 1306 and produces a digital signal DSG in the microcontroller 1312'. Circuit 1316' power supply is connected with the generator 1306 carrier. In addition, the sensor 1320' transceiver is connected with the circuit 1316' of the power supply and microcontroller 1312'. As such, the sensor 1320' receives electrical energy from the circuit 1316' power supply and outputs a signal TSS to the microcontroller 1312'. The microcontroller receives signals TSS and DSG and performs one or more operations using these signals. After that, the microcontroller 1312' interacts with located next systems and/or devices, as shown in the General form of the arrow 1314.

The defendant 1304 schematically shown in Fig and contains the antenna 1322, suitable for receiving the carrier CWV. Power circuit 1324 is connected with the antenna 1322 and allows you to store electrical energy from it, as already mentioned here above with reference to other options. The microcontroller 1326 is connected with the power circuit 1324 and receives electrical energy from it. Shaper 1328 is connected with the antenna 1322 and microcontroller 1326 and produces an output signal SCL, which contains one or more scaled electrical characteristics or parameters, such as voltage or current signal from the antenna 1322.

The sensor 1318 is connected with the power circuit 1324 and microcontroller 1326. The sensor receives electrical energy from the power circuit 1324 and kind of the em output signal SNR on the microcontroller 1326. As such, the sensor 1318 receives electrical energy from the power circuit 1324 without using other external wires, giving him electric energy. Receiving power wirelessly, the sensor generates an output signal SNR, which is transmitted to the microcontroller 1326. If necessary, can be used one or more additional sensors 1330, operatively combined with the defendant 1304, which, in accordance with one exemplary variant, can receive power from the power circuit 1324 and to transmit the corresponding output signals of the sensor SNR2-SNRNthe microcontroller 1326, similar to the sensor 1318.

The sensor 1318 and sensors 1330, if they exist, may be of any suitable type, kind, configuration and/or design and create an output signal carrying information on the measured parameter. As examples of sensors can lead to (but not limited to, accelerometers, pressure and temperature sensors or thermocouples. It should be borne in mind that the experts in this field can choose any suitable sensors and to quickly connect them with the appropriate Converter. When choosing the appropriate number and layout of sensors and selecting specific sensors for use, you should consider the amount of electrical energy generated by the transducer and neo is required for operation of its electrical components, moreover, it is desirable to obtain electrical energy from one or more sources of energy without wires.

Shunt circuit 1332 has electrical communication with the microcontroller 1326 and antenna 1322. Shunt circuit 1332 allows you to change the inductance of the antenna 1322 due to its selective activation using microcontroller 1326. Due to selective activation of the shunt circuit 1332 and create a corresponding change in the inductance of the antenna 1322 can be excited by a modulated carrier CWV, as shown sinusoidal oscillations IM2. In accordance with an exemplary option, the microcontroller 1326 selectively activates the shunt circuit 1332 for excitation modulation carrier CWV scheme suitable for data transmission in the corresponding transceiver, such as transceiver 1302. Can be used in the circuit of any suitable type or kind, which may be of any suitable shape or configuration, including this can be a direct transmission or an encrypted transmission, such as frequency shift keying and phase shift keying, which was discussed here above. Data generated by selective activation of the shunt circuit 1332, produced by the microcontroller 1326 in response to the output signal SCL shaper and, additionally or alternatively, at the expense of the output signal SNR Dutch is CA. If necessary, additional output signals SNR2-SNRNsensors can be entered in the data generation process, if such additional sensors operatively interact with the defendant.

Moreover, it should be clearly understood that the data can be received and/or transmitted in any suitable form or in any suitable way, and the following examples simply explain the proper operation of determining orientation and information exchange, and that alternative can be used in any other suitable way of receiving and/or transmitting data. For example, each signal (for example, the output signal SCL shaper and output signals SNR2- SNRNsensors) can be converted to an individual message with a specified number of bits or bytes, and each message contains the ID of the source signal and the corresponding signal value. Data from each sensor can be transmitted and received with high or low frequency. For example, acceleration data can be transmitted and received approximately 1000 times per second, data on height can be transmitted and received approximately 100 times per second, and data on pressure or temperature can be transmitted and received approximately 1 time per minute.

In accordance with another example, can be created messages having a specified number of bits or bytes that contain a specified number of bits or bytes for each output signal. For example, in the case of the Respondent, with the acceleration sensor and a pressure sensor, a message can have only eight (8) bits, with the first three (3) bits correspond to the distances, the following three (3) bits correspond to the acceleration, and the remaining two (2) bits correspond to the pressure. The message can be created and sent at a frequency that is needed for the data of the high output signal, and the data of other output signals ignored or removed otherwise, if and/or when such data is not used.

Shown in an arrow-shaped contact clip 1414 is connected to the wire 1422 next to the throttle, which is shown in Fig using the standard symbol. However, it should be borne in mind that it may be desirable adjustment or optimization of the antenna so that it can communicate with any other antenna, such as antenna 1308 transceiver 1302.

The sensor 1412 operatively interacts with the defendant 1400 and, in accordance with one exemplary variant, made in the form of a single whole with him. However, it should be clearly understood that the described sensors, including (but without limitation) sensors 1318, 1320', 1330 and 1412 of any suitable type may be designed, configured or installed any suitable manner on the interacting defendant or as a separate component that is installed or mounted otherwise close to him that it is not beyond the scope of the proposed new concept and in line with its principles.
