AREA of TECHNOLOGY

The invention describes a system and a method of controlling a device by sending the device control signal through the repeater module. The invention also describes a repeater module and the interface module remote control.

PRIOR to the expiry LEVEL of EQUIPMENT

Many currently available devices for the consumer electronics can be controlled remotely, through the use of wireless modules for remote control, usually portable. The user can easily select the desired device functions by, for example, pressing the appropriate button or sequence of buttons on the remote control module. Some modules remote control can be programmed to provide the ability to control multiple electronic devices, for example, can be used "universal" remote control unit to control a TV, CD-player, satellite receiver, etc. US 2007/0139214 A1 describes a system in which modules remote control is not tied to specific devices, but can receive remote control commands for any device from the Central controller.

Control signals issued by the remote control�Oia for the detection of the managed device, can be infrared signals or radio frequency signals. Typically, the power source remote control device is a battery or battery pack. The remote control unit must be small enough and light weight enough to provide a comfortable hold when using. Consequently, for ease of use, the power source of the remote control unit also needs to be light in weight. These size limitations may also impose limits on signal power, which can generate a remote control unit. This in turn may limit the range at which the remote control unit can communicate with the device.

Known is the use of a repeater to relay the signal from the source to the target when the source and target are at such a distance that cannot communicate directly with each other. However, the known repeater modules require separate power sources, either from the mains or from the battery, and consequently will only be added to the total energy consumption. As many users of consumer devices begin to realize the negative impact on the environment exerted excessive energy�consumption and would prefer to reduce unnecessary energy consumption, we can expect that the additional consumption of such repeaters of the prior art will be considered as unacceptable. For many consumers may be unacceptable even to the repeater module, made with standby mode, as there is a growing understanding that we need to reduce power consumption, even with respect to power in standby mode. EP 1857911 A1 describes a device with a Wake-up module for the detection of the Wake-up signal and the connection of the main unit of the device to a power source. US 2006/0101298 A1 also describes a device with a Wake-up module, in which the amplifier carries out a tracking signal. When you detect the Wake-up signal, the device connects to a power source, and the amplifier is disconnected from the power source. However, when tracking of the Wake-up signal, the amplifier continuously consumes current from the power source.

SUMMARY the essence of the INVENTION

The object of the present invention is to provide a method of remote control of the device outside the range of the remote control unit, thus to eliminate the above mentioned disadvantages.

Object of the invention is solved by a system control device according to paragraph 1 of the claims, by means of the repeater module on the item� 6 of the formula of the invention and by means of a method of controlling the device according to paragraph 10 of the claims.

The system in accordance with the invention comprises a remote control unit for signal transmission in the form of electromagnetic radiation, the repeater module and the controlled device. In accordance with the invention, the repeater module comprises: a detector for detecting electromagnetic radiation to obtain the signal reception repeater; a first conversion module signal for the passive conversion of the received signal repeater in the excitation signal switching repeater for actuating the first switch to switch the repeater module between an inactive mode, wherein the repeater module is completely disconnected from the first power source so that current is not consumed by the repeater module, and the operating mode in which power is consumed by the repeater module from the first power source; a signal module, fed by the first power source for generating transmission signal repeater on the basis of the received signal repeater; and a transmission interface of a repeater for signal transmission repeater in the form of electromagnetic radiation. In the system in accordance with the invention, the managed device contains the interface module remote control for the detection of electromagnetic radiation transmitted by the transmission interface repeater �for obtaining the signal receiving device, the signal receiving device is subsequently used as the basis for device management.

Used herein, "device" may be any electronic device that responds to an acceptable control signal, for example, any remote controlled device consumer electronics, household appliance, lighting, etc.

In the system in accordance with the invention, electromagnetic radiation is automatically detected in the repeater completely passive manner by the detection module or the detecting antenna, where the electromagnetic energy is called resonance, forming a signal repeater. Also, the conversion of the electric signal of the alternating current in the excitation signal switching repeater DC is completely passive manner, i.e., through the use of electrical components that do not require a power source. The advantage of using a repeater for signal transmission, is that a remote control unit used to activate or deactivate the device can be placed outside of its transmission range, since the repeater module detects the signal destined to the device, and retransmits the signal. In addition, �Odul remote control should not be withheld "line of sight" devices since the module of the repeater may retransmit the signal in any direction. A particular advantage of the system in accordance with the invention is that when the repeater is deactivated, it is completely disconnected from its power source, in the true state of "zero consumption" and not just in the mode with low power consumption, known in modern devices, which is usually referred to as "standby". In accordance with the invention, the repeater when it's off, is completely at rest, as it does not consume current and does not consume energy, so the obvious advantage of the system in accordance with the invention is the conservation of energy, which can be obtained with a positive increase in the range of the remote control. Another advantage is that the repeater can still be re-activated by a remote control unit, so in no way compromised the convenience and ease of use. Collectively, this provides a convenient and comfortable way to manage one or more devices even if the devices are outside the range of the remote control, thus, without a significant increase in total energy consumption with�system.

In accordance with the invention, the repeater module to transmit a signal from a remote control unit for a controlled device comprises a detection module, for detecting electromagnetic radiation to obtain a signal repeater, and the first conversion module of the signal for the passive conversion of the received signal repeater for receiving the excitation signal switching repeater. The purpose of the excitation signal switching repeater consists in switching repeater between an inactive mode in which the repeater module is completely disconnected from the power source to the repeater so that the repeater module is not consumed is no current, and the operating mode in which power is consumed by the repeater module from the power source to the repeater. The repeater module in accordance with the invention also contains an alarm module, which is powered by a power source of a repeater for signal transmission repeater on the basis of the received signal repeater, and the transmission interface of a repeater for signal transmission repeater in the form of electromagnetic radiation.

In accordance with the invention, a method of controlling the device comprises phases in which: transmit the control signal from a remote control unit in the form of electromagnetic radiation�Oia; detects electromagnetic radiation through the interface receiving the repeater in the repeater to get the signal reception repeater; passively convert the signal reception repeater in the excitation signal switching repeater; and actuate the switch repeater repeater module, using the excitation signal of the switching repeater to switch the repeater module between an inactive mode in which the repeater module is completely disconnected from the power source to the repeater so that the repeater module is not consumed is no current, and the operating mode in which power is consumed by the repeater module from the power source to the repeater. Method in accordance with the invention further comprises a step in which, using the power source follower for actuating a signaling module of the repeater module on the basis of the received signal repeater for signal transmission repeater, and the stage at which transmit the transmission signal repeater in the form of electromagnetic radiation through the transmission interface of a repeater module the repeater. In the method in accordance with the invention, electromagnetic radiation transmitted by the transmission interface of a repeater, detect module in the remote interface of the managed device�and to receive the signal receiving device, the signal receiving device is used as the basis for device management.

The dependent claims and the subsequent description disclose a specific priority implementation options and features of the invention.

In a particular preferred embodiment of the invention, the passive module conversion module of the repeater contains a passive rectifier circuit, so the electric AC signal induced in the detecting or receiving antenna is converted into a DC signal without using any active components. For this reason, the described passive rectifier circuit, may simply contain passive components such as, for example, high-frequency diode in conjunction with a capacitor to generate the smoothed excitation signal switching DC power signal which is sufficient for the operation of sensitive electrical switch. Thus, the signal transmitted by the remote control unit may be converted, in a completely passive manner, the excitation signal switching repeater to connect functional elements or modules of the repeater to the power supply of the repeater.

The development of technology, the�nologies in recent years has led to improved and more sensitive electrical switches for example, the switch MEMS (microelectromechanical systems), which can be switched using very weak signals. Such switches, unlike modern switches do not require amplifiers, such as operational amplifiers. Consequently, in one embodiment of the invention, the switch of the repeater contains a MEMS switch that can switch weak excitation signal switching repeater. Alternatively, the excitation signal switching repeater can switch CMOS FET (field-effect transistor, made by technology of complementary metal oxide semiconductor) between the power supply of the repeater and the repeater module. The possibility of such switches are known to the person skilled in the art and do not require here a more detailed explanation.

The advantages associated with the ability to perform full connection to and disconnection from a power source via a remotely transmitted signal, is not limited to the repeater module. Undoubtedly, any device controlled by the remote control unit can also use the benefits of a complete disconnect from power source when not in use. Consequently, in a preferred embodiment of the invention, the interface module remote�nianogo management managed device contains a module passive conversion signal and the power source switch device. Consequently, the signal receiving device may passively be converted to the excitation signal switch and the power switch device can operate using the excitation signal for switching the switching device between an operating mode in which the current consumed by the device during operation of the power source device, and an inactive mode in which the device is fully disconnected from the power supply device so that the device consumes no current. Passive signal conversion module in the remote interface can be performed similarly to that described above, using passive components of the circuit for obtaining excitation signal switching device. Consequently, the power switch device interface module remote control can preferably be switched or actuated by the excitation signal switching device for switching a controllable device between an operating mode in which the current consumed by the device during operation and an inactive mode in which the device being controlled is completely disconnected from the power source device, so that no current device is not consumed. Again, the power switch of the device may be as described above�, switch MEMS or CMOS FET. Alternatively, in a further practical embodiment, the optical coupler or optocoupler, for example, containing LED (led) as the light source and the phototransistor or photoemitter as a sensor, can be used as a power switch device between the conversion module of the signal of the remote interface device and, as the optocoupler has a suitable electrical insulation of the module converting the signal from the device.

As already indicated, the user can control the device in the usual way by, for example, pressing one or more buttons on remote control module. Consequently, in an additional preferred embodiment of the invention, the remote control unit has a user interface for inputting a control operation and a signal generator for generating a control signal according to the control action. In one possible embodiment, for example, the remote control unit may include a dedicated button on/off switch for transmitting a specific signal to the repeater module, which tells the repeater module to perform the connection or disconnection from its source� power and any other buttons or means of interaction in the user interface of the remote control unit can be assigned in the usual way the device functions. However, as any electromagnetic radiation of sufficient power can serve as an activator of the repeater module, such dedicated button on/off switch is in an explicit form is not needed, and the principle of operation of the repeater module may consist of simple to activate (if it was previously disabled) when detecting any signal reception repeater. Then detection of the signal just is relayed to the transmitting antenna of the repeater, which is connected to a power source of a repeater. The advantage of this variant implementation can be that the system in accordance with the invention can find its application, using already existing modules remote control and corresponding devices.

Many well-known modules remote control communicate with the managed device through the infrared interface, as mentioned above. For these modules remote control, the device must be in line-of-sight, so the connection was successful. However, the system and method in accordance with the invention can be used together with this module� remote control for to activate a device that has been disconnected from its power source as described above. Consequently, such a remote control unit is preferably equipped with an additional interface, is capable of forming a radio frequency signal that can be detected by the repeater module and then relayed to the device with the corresponding module infrared remote control interface. For example, a remote control unit with additional generator RF signal and transmitting antennas can be used to output a signal of "awakening", which can be a low power signal, for detecting the repeater module, which in turn, relays the Wake-up signal to the intended device. Once the power source switch of the device was powered to connect the device to its power source, the remote control unit can be used for communication with the functional device through the infrared interface. However, in another embodiment of the invention, the repeater module may also contain an infrared interface for increasing the distance between the remote control unit and one or more devices�and, which are managed by means of infrared control signals. The repeater module is preferably equipped with a suitable infrared interface for receiving and repeater infrared signals. The repeater module may also include an amplifier to increase the signal power applied to the infrared control signals before they are to be relayed, thereby largely increasing the operating range between the remote control unit and device. Since the beam of infrared radiation is preferably directed to the device so that it can properly be taken, the repeater module in accordance with the invention, in this embodiment, may preferably be arranged to transmit in the direction of the managed device. A stage configuration can be performed manually, e.g., by the user. Alternatively, for greater ease of use, the repeater module may include a lens, such as a fractal lens or a Fresnel lens to distribute the infrared signal to a large area, thereby allowing management of multiple devices.

Recently for control of consumer electronics devices used modules remote control with radio frequency interface�AMI. For this type of remote control is in direct line of sight, so that, in the system and method in accordance with the invention, can be achieved a much larger range in comparison with devices based on infrared interface. In this case, the repeater module not only relays the device Wake-up signal, but can be used for any repeater control signal issued by the remote control unit and designed the device, in accordance with the user input. The remote control unit does not have to be a portable device, and may be part of devices, such as wireless wall control in the layout ZigBee.

Obviously, with such modules remote control system in accordance with the invention is not limited to the use of a single module of a repeater. For example, between a remote control unit and a controlled device may be a series of repeater modules. This allows the user of the remote control unit to move freely, while maintaining the ability of the remote control device. The repeater modules are arranged such that the signal coming from the remote control unit and�and from the repeater module can be detected the closest repeater module, which in turn relays the signal.

In ZigBee environment or in an environment that is based on a similar standard, for example, separate physical objects can combine the functionality of the remote control module, the repeater module and the device. For example, a single physical object can be a device with one or more functions of the device, and also may include a repeater module for forwarding control signals coming from the remote control module, another module of a repeater or other device. Possible variant implementations may be some amount of lighting is controlled in such environment, each of a certain number of lighting - which can be viewed as "devices" - contains a repeater module for forwarding control signals intended for the receiver.

In a simpler embodiment of a system in accordance with the invention, a home entertainment system can include CD player, located in the center, with the arrangement of the loudspeakers in different rooms or on different floors. The user can control home entertainment system from anywhere in the room using a remote control unit. Well located some quantities� repeater modules can be used to detect and retransmit the control signal, coming from a remote control unit. The repeater module closest to the device - in this case the CD player - delivers the control signal to the interface module remote control device. Thus, the user can comfortably operate the device, located at any distance.

When the repeater module is used to forward or relay the signal issued by the remote control unit, the signal itself may be forwarded, in essence, unchanged. However, in order to a greater extent to ensure that the signal can be detected intended device, the signal strength may increase. Consequently, in an additional embodiment, signal repeater module the repeater module preferably comprises an amplifier to amplify the signal reception repeater to output a signal transmitting repeater. In this variant implementation, the transmission signal repeater, being a signal with more power, can better be detected by the device, thereby ensuring a large distance covered.

As mentioned above, one particular advantage of passive detection and conversion of the signal in combination with the described actuation switch�carriers, what electronic device such as a repeater module can be completely disconnected from its power source when not in use. This deactivation can occur when detecting a signal issued by, for example, a remote control unit. However, this would require the identification of such a signal and use a dedicated circuit for signal detection in the signal reception repeater. Consequently, in a particular preferred embodiment of the invention, the repeater module includes a timer module to provide time-dependent output signal after a predefined duration of time from detection of the received signal repeater, and to control the excitation signal switching repeater to switch the repeater module is in an inactive mode in which the repeater module is completely disconnected from the power source to the repeater so that the repeater module is not consumed any current. Whenever the signal reception repeater is detected, can be initiated by the module timer or counter. As soon as the counter or the timer module reaches a predetermined value, for example the value of a corresponding to five minutes, half an hour or any acceptable value, you may receive an alarm opened�then need to switch the repeater to disable the repeater module from the power source to the repeater. Thus, the user does not need to take additional steps to deactivate the repeater module. Alternatively, in an additional embodiment, the implementation, the functionality of the timer module can be combined with modern type of functioning in the "standby" mode, so that in the interval between the control signals when the timer module counts down elapsed time, other circuits of the repeater module can transfer to the "standby" mode, so that the circuit consumes minimal current, in "anticipation" of the next repeater control signal. When another signal is detected the reception of the repeater, while the timer is still counting time, then it causes the return of the scheme to its "normal" operation, i.e., the relay control signal. At the expiration of a predetermined period of time without detecting any signal repeater, the timer module can produce a radio repeater, as described above, to switch the repeater module in the condition of zero consumption.

To enable user feedback, the repeater module can be equipped with a LED that glows whenever the repeater module is activated, i.e. whenever the modules of the circuits of the repeater module is connected� to its power source. Thus, the user can be sure that the repeater module is functioning. When the power supply of the repeater is shut off again after a predetermined period of time, then the LED also turns off automatically.

In order to minimize interference between devices that exchange wireless signals, the wireless communication is governed by standards that, among other things, assigns frequency bands for use by devices of different types. For example, wireless local or personal area network (LAN or PAN), with a range of up to 100 meters, can be performed on the frequency band ISM (international bandwidth for scientific and medical organizations). Consequently, in a particular preferred embodiment of the invention, the electromagnetic signals generated by the remote control unit and relayed by the repeater module, made in the form of high-frequency signals whose frequency lies in the frequency band ISM. There are several such strips, with a Central frequency equal to 2.45 GHz, 915 MHz or 5.8 GHz.

Depending on the area of application in which the system is used in accordance with the invention, or from the distance between the repeater modules and devices can be used in other frequency bands. Example�, modules repeater system can be implemented for operation at frequencies compatible with the applications of communication systems, short range (Bluetooth), medium range (ZigBee) or even long range (DECT, GSM). Devices intended for use in such environments can be easily extended functionality of "zero consumption" in accordance with the here described system and method, so that the total power consumption in such environments can be usefully reduced through the provision of devices to be switched off in a state of true "off" and re-activated by a remote control unit.

The RF signal generated in the module of remote control, can be formed continuously, i.e. as a continuous signal without pauses. However, in a preferred embodiment of the invention, the signal contains high frequency pulse signal, i.e. signal generator remote control unit emits a series of high frequency pulses, it is possible by means of a suitable condenser, as is well known to specialists in the relevant area. One advantage of this method is that it prolongs the life of the battery supplying the signal generator. More significant is�I, that surge can effectively increase the capacity, i.e. the amplitude of an electrical signal, so that the reliability of the switching process. At the same time, it can be guaranteed that not exceeded a total average power of the signal and thus the signal meets the security standards. Also, this method allows to increase the range of the signal. Again, the thus generated signal may be a predetermined duration, or may be formed during the time at which the user performs the appropriate action using the remote control unit. The repeater module in accordance with the invention preferably is implemented for the transmission of such a pulse signal. For example, the signal may be relayed by the repeater module unchanged, or may increase, as described above.

Consequently, in a particular preferred embodiment of the invention, regardless of the nature of the received signal repeater, the information content of the transmission signal repeater corresponds to the information content of the received signal repeater. In other words, the signal module is implemented so that any information contained in the received signal repeater, will be diverted in the signal PE�of Adachi repeater. For example, a device ID, device ID, information about modulation, etc., encoded in the signal reception repeater, preferably also encoded in the transmission signal repeater.

As mentioned above, the system and method in accordance with the invention can be used to provide the user the ability to control multiple devices. To manage the multitude of devices available portable modules remote control, for example, the user can select whether the command sent to the TV, satellite receiver, etc. This remote control unit can generate the signals modulated at different frequencies, with each frequency is associated with a particular device. Alternatively, the control signals for different devices may contain carrier signals modulated to carry information identifying the device, such as the identification code of the device as applied to a managed device. This code identify the device may be, for example, the code type RFID (radio frequency ID), familiar to a person skilled in the relevant field. Such means of identification may be advantageous when multiple devices are controlled by modules remote control, IP�alsoa method in accordance with the invention, or, in particular, when the remote control unit is used to control more than one device. In this case, the remote control unit can be equipped with different buttons for addressing different devices, and each device that is activated and deactivated by the remote control module, driven switch opens or closes based on the information identifying the device. Consequently, in an additional preferred embodiment of the invention, the received signal is decoded to determine the identification code of the device and the power source switch device is actuated based on the identification code of the device. For example, the signal handoff repeater, may be taken by the interface modules remote control multiple devices, but in reality to operate will be the power source switch device applied to the device for which it was intended signal.

Further developing this concept, the system in accordance with the invention may be considered "smart" forwarding control signals to devices. This can be an advantage in systems that use a plurality of modules repeat�'el and many managed devices, similar to ZigBee systems. The device can be lighting, electronic door locks, fans, etc., for example, in an office building. In such a scenario, the repeater module in accordance with the invention is preferably implemented to relay the signal control device only if the device that received the signal control device is within range of the repeater. "The range of the repeater module can be its transmission range, but may also be its "logical range. For example, ZigBee or similar environment, the repeater module may opt-out of forwarding another signal, if the repeater module can not reach the device that received the signal. From this point of view, the modules of the repeater system may be configured on the initial configuration so that each repeater module "knows" which devices are located within its transmission range. The signal, detected by the repeater module, then decoded and relayed only if the device code in the signal indicates that the signal is intended device within range of the repeater module. In such a system, there is a possibility that the control signals� devices not just are issued a portable remote control unit, and can be formed by the system controller, for example, using a computer connected to a radio frequency transmitter.

As already indicated, the control signal source device is formed in a module, remote control, and is transmitted through the transmitting antenna. The antenna is the simplest type radiates in all directions, so that the power of the transmitted signal is also distributed in all directions. This leads to the fact that only a small portion of the signal power reaches the antenna detection, and in this case, the receiving antenna of the repeater module. As a result, such a signal must have sufficient amplitude to be reliably detected. An example of such a simple antenna is a dipole antenna. However, the range of the wireless signal can be increased using a directional antenna, as is well known to specialists in the relevant area. Examples of modern antennas, suitable for use in wireless communication of small radius of action is a printed antenna printed or micro antenna. Alternatively, can be used in phased array antenna, for example as described in WO 2005/086281 A1. Consequently, in the system in accordance with the invention, the transmitting antenna module remote control� can be made in the form of directional antenna, so that the transmission output, in fact, focused mainly in one direction. The user only needs to send a remote control unit in the General direction of the nearest repeater module to ensure that the signal is reliably detected by the repeater module.

In an additional preferred embodiment, the radiation characteristics of the transmitting antenna are consistent with the characteristics of the radiation receiving antenna. This applies to couples of the transmitting/receiving antenna in relation to remote control unit/module of the repeater; the repeater module/module repeater; and the repeater module/control unit. In one or more of such pairs of antennas in the system in accordance with the invention, the radiation characteristics of the transmitting antenna are consistent with the characteristics of the radiation corresponding to the receiving antenna so that the electromagnetic radiation from the transmitting antenna, the optimum way is detected by the corresponding receiving antenna. For example, the radiation characteristics can include characteristics of polarization, which are then aligned in a pair of transmitting/receiving antennas.

The repeater module in accordance with the invention has functionality for receiving, as well as the transmission. In OS�Aries, the module of the repeater retransmits the same signal it receives. Consequently, in an additional preferred embodiment of the invention, the repeater module comprises an antenna, the shared functions for reception and transmission. In order to allow the repeater module, essentially simultaneously receive the signal and retransmit the same signal, after amplification, can be used corresponding electronic switch. Alternatively, above the signal reception repeater can run a quarter-wave transformation, in order to enable the use of a shared antenna.

DETAILED DESCRIPTION of PREFERRED embodiments of the INVENTION

Fig.1 depicts the current situation with the original remote control device 8, in this case a TV, and module 2 remote control, which is usually managed by a user (not shown) at a variable distance d from the device 8. The user presses certain buttons on the module 2 remote control to turn on the device 8, to change device settings, for example, to change channel or adjust the volume of the speakers or of the transfer device 8 to the standby mode. Shows the current module 2 remote control operates by forming an RF control signal transmitted as electromagnetic radiation 4. When the module 2 remote control is pointed at the device 8, the signal may be detected with a suitable interface device 6 in 8 and converted into corresponding signals of the control device. In the modern system, the device 8 can detect the signal issued by the module 2 remote control only when the distance d is not greater than the range R of the action module 2 remote control. In other words, if the user moves the module 2 remote management so far from the device the device 8 will be outside the range R of the action module 2 remote controls, any signals given by the module 2 remote controls, will be so weak that they can no longer reliably be detected by an interface 6 remote control device 8.

Device 8 consumes current from the power source indicated on the scheme through the outlet 7. In standby mode, the device 8 is completely disconnected from the power network as the interface 6 requires a small amount of energy in order to be able to respond to the activation signal 4 from module 2 remote control. In addition, a small current is constantly consumed typical "LED standby" 5, which emits light as the location of the device 8 is in the standby mode. If the user wishes to completely disable device 8 from the power source when not in use, it should do so directly, for example, by pressing the on/off switch on the device 8 or the disconnect device 8 from the power outlet 7.

Fig.2 depicts a block diagram of a first embodiment of the system 1 in accordance with the invention. Major elements of the system 1 are the repeater module 10, the controlled device D and the module 30 remote control for you�ACI commands to manage the device via RF signals. Module 30 remote control can be a portable module of the conventional type. The device D may be any suitable device, such as a consumer electronics device connected to a network source of the P20power, such as a television, satellite receiver, lighting device, etc., and is shown here as having a payload of 24, representing the load of the device D during operation. The device D can also be any managed device, for example, to install ZigBee or Bluetooth. For clarity, the significant components of the module 30 remote control module 10 of the repeater and the device D is an emphasis with reference to other components, so to be able to better explain their functionality.

The repeater module 10 may be a compact module that is placed essentially between the module 30 of a remote controller and a controlled device D, for example, the repeater module 10 may be performed on the ceiling, so as not to attract attention. Module 10 repeater has its own source of P10power, which may be any acceptable power source such as battery, solar cell or AC adapter. When not in use, i.e. when the module 10 of the repeater is inactive, he is completely disconnected from the source of the P10power the repeater. To�Yes is used i.e., when the module 10 active repeater, as will be explained in detail below, the source of P10power repeater connected to the module 10 of the repeater, which requires a power source.

Module 30 remote control can be powered in a conventional manner, for example, using a block of 32 batteries, piezoelectric sensor, etc. To select the function of the device D, the user (not shown) may use the interface 31, for example, a set of buttons module 30 remote control. When the button is pressed, the corresponding signal 33, the controller interacts with the switch 34 to supply power to the generator 36 of the signal, thereby causing the formation of an electrical signal 35, which in turn causes respectively to resonate transmitting antenna T30module 30 remote control, so that electromagnetic radiation EM1is transmitted through the transmitting antenna T30. The generator signal 36 can generate an electrical signal 35 continuously, until then, until the user releases the button on the interface 31, as a pulse signal (to increase signal strength), or as a carrier signal modulated to transmit information identifying the device, such as an RFID code. Specialist in the relevant field knows how m�can be implemented by a corresponding oscillator signal 36 for to perform such functions, for this reason, it does not require additional consideration.

Electromagnetic radiation EM1passed module 30 remote control reaches the repeater module 10, in which the R10detection, in this case the receiving antenna R10repeater, respectively resonates in such a way that signal is generated 11 reception repeater AC. Signal 11 receiving passive repeater is converted in the module 12 convert the signal into a 13 excitation switching repeater DC. If the module 10 repeater was previously inactive, the switch S10will be in open condition, i.e., the source of P10power repeater was previously disconnected from the module 10 of the repeater, so that no part of the module 10 of the repeater does not consume any current. Nevertheless, as only in accordance with what is described, a signal is generated 13 excitation switching repeater, switch S10closes and the module 10 of the repeater are connected to their source of P10power.

Signal 11 reception repeater, which essentially corresponds to the control signal 33 generated in response to user input, can then be forwarded by the module 10 of the repeater device D, which would� is the control signal 33. From this point of view, the signal 11 of the receiving repeater passes the signal module 14 module 10 of the repeater where the signal 11 of the reception of the repeater can be amplified or otherwise processed for signal 15 transmission of the repeater, which in turn is transmitted as electromagnetic radiation EM2transmitting antenna T10repeater.

Through an appropriate selection of electrical and electronic components in the respective modules 14, T10module 10 repeater transmitted electromagnetic radiation EM2can have at least more power than electromagnetic radiation EM1the source transmitted by the module 30 remote control. For example, the signal module 14 may include an amplifier. Thus, the range of the provided radio frequency signals controlling device between the module 30 and remote control device D may preferably be increased without any significant additional energy consumption from the module 10 of the repeater, as it is only activated - i.e. it connects to a power source P10- when the signal is issued by the module 30 remote control is detected by the receiving antenna R10.

On the side of the device for electromagnetic emissions� EM 2is detected by the detection module, in this case the receiving antenna is R20for receiving the signal 21 of the reception device. The signal 21 of the reception device is decoded or processed in the usual way interface 27 device management module 20 of the remote interface device that respectively generates signals 28 device management, for example, the signal 28 of the control device to change the channel or adjust the volume if the device D is a TV. Operation of such an interface 27 device management known to the expert in the field, and requires no description here in any detail.

Fig.3 depicts a second embodiment of the system 1 in accordance with the invention. Again, the module 30 remote control is used to issue control signals in open space in the form of electromagnetic radiation EM1in order to control the device D. the repeater Module 10 between the module 30 and remote control device D can be used to detect electromagnetic radiation EM1issued by module 30 remote control, and forward it to the device D.

Here, the device D has not only the interface 27 of the control device, but also includes a module 20 �of interface remote control module 22 passive component signal and the switch S 20for full connection of the device D to the source of P20the power or disconnect the device D by P20power. The operation of the module 22 passive conversion signal, and switch S20essentially similar to corresponding modules 12, S10in module 10 of the repeater. In fact the electrical components in the module 12 conversion signal repeater and module 22 signal conversion device can be the same. However, since the device D, as a rule, will be a big load 24, and the switch S20the power source should be chosen accordingly.

As shown, the system has the advantage consisting in the fact that the device D can also completely disconnect from their source of P20power when not in use (for example, when the user presses the button "off" on the module 30 remote control), and can also easily be activated by a signal 35, issued by the module 30 remote control (for example, when the user clicks on the button "enable" on the module 30 remote control) with greater range than is possible using modern module 30 remote control, thanks to the repeater module 10, which increased�t and retransmits the RF signal on/off the device issued by module 30 remote control.

The range covered by the signal control device can be further increased by using a larger number of modules of the repeater between the remote control unit and device(s) system. Fig.4 depicts an example implementation. Here, the module 30 remote control converts the user input into electromagnetic radiation EM1that is detected by the first repeater module 10, the closest to the module 30 remote control. This first repeater module 10 detects, amplifies and retransmits the signal as electromagnetic radiation EM2that in turn is detected by the second repeater module 10 located much farther from module 30 remote control, but closer to the device D. This second module 10 repeater amplifies and retransmits the signal as electromagnetic radiation EM2'that, in the end, and is detected by the device D. depending on enabled/disabled status of the device D and the contents of the control signal, the interface 20 remote control device D can cause the device to its power source, can cause the disconnection of the device from its power source, Il� may generate a signal control device for controlling the device in accordance with the function selected by the user. Fig.4 also shows a second device D', which can also be controlled by the same module 30 remote control. Here, the second device D' can be used to detect electromagnetic radiation EM2coming from the first module 10 of the repeater.

Fig.5 depicts a fourth embodiment of the system 1 in accordance with the invention. Again, the module 30 remote control is used to control the device D. the repeater Module 10 between the module 30 and remote control device D can be used to detect electromagnetic radiation EM1issued by module 30 remote control, and forward it to the device D.

In this embodiment, the implementation module 30 remote control contains an infrared interface 37 with an infrared diode 38. Module 30 remote control also contains a generator 36 of the RF signal, and transmitting antenna T30as was described earlier. For clarity, the diagram does not show the battery module 30 remote control, but it is clear that it should be included. Here, the module 30 remote control is able to generate the RF signal 33 on/off device for the transmission of the transmitting antenna T30as however , and the infrared signal 39 of the control device functions DL� infrared transmission diode 38. These signals 33, 39 can be formed in the interface 31 of the user in a conventional manner, for example through the use of dedicated buttons, such as button on/off button, channel selection, etc.

The device D includes not only infrared interface 27 of the control device for the detection and interpretation of infrared signals from the module 30 remote control, but also the module 20 of the remote interface and the switch S20to completely disconnect the device D from its source of power P20as described above with respect to Fig.3. The second module 22 signal conversion converts the signal 21 of the reception device in the signal 23 of the excitation device.

Module 10 repeater can also be used to increase the range between the module 30 and remote control device D having, in this example, "only" an infrared interface. From this point of view, the repeater module 10 can also be equipped with an infrared interface (not shown) for receiving and repeater infrared signals, as well as radio interfaces described above. Thus, the repeater module 10 can easily detect the infrared signals sent from the module 30 remote control, hi�renepreval them to the intended device D. Undoubtedly, in this case requires that the conditions for finding the module 10 of the repeater in the line of sight module 30 remote control and locate the device D in the line of sight of the repeater module 10.

In the above-described using Fig.2-5 embodiments, the repeater module, the switch S10can be closed up until you detect the signal 11 of the receiving repeater. Once the signal 11 of the receiving repeater reaches zero, the switch may again be opened. However, it may be convenient to leave the switch S10in closed condition for a longer period, so as to increase the productivity of interactions in remote control between the user and the device. Object of the invention, namely to provide increased range in the remote control system and to improve user interaction, while maintaining minimal power consumption can be further extended with a repeater module, which in turn can off - i.e. to release your power source switch - on the expiration of a predetermined period of time. Variant implementation of such a module 10 of a repeater shown in Fig.6. Here, the repeater module 10 includes the already described� components and modules - module 12 conversion signal, the switch S10repeater receiving antenna R10and transmitting antenna T10the signal generator 14 and an additional module 17 of the timer. The signal, detected receiving antenna R10and passively converted to a signal 13 to the excitation switching repeater, as described above, actuates the switch S10that takes the energy is not passive repeater parts circled in the diagram by the dotted line. As soon as the switch S10closes, as a result, this triggers the start of the module 17 of the timer. Module 17 timer can contain a counter with the stored predetermined value to the upper bound corresponding to the time limit. Once achieved a predetermined value, the module 17 timer 16 produces a signal control switch to cause the switch S10once again open. Thus, the repeater module 10 can be completely disconnected from its source of P10power at the expiration of a predetermined time, e.g., several minutes since the last detection of the received signal repeater. This may enable the relaying device a sequence of control signals from a remote control unit without disconnecting the module 10 p�of Veritas by P 10power. Such time period may be sufficient for configuration by the user of the home entertainment system, for example, to turn on the CD player and select a track, or to turn on the TV and satellite receiver and select the channel. Subsequently, the repeater module 10 may again to "sleep" in its inactive state, is disconnected from its source of P10power. The next time the user clicks a button on a remote control module (not shown), the switch S10again closes and the module 10 of the repeater is activated again.

Further, Fig.7a, 7b, 8a, 8b, 9a and 9b will be used to describe passive signal conversion module of a repeater, by way of illustration of the levels of electromagnetic radiation emanating from a control signal transmitted by the transmitting antenna of a remote control unit and detected by the repeater module. However, it should be clear that the described scheme can equally be applied to the signal conversion of electromagnetic radiation originating from the repeater module and the detected receiving antenna in the remote interface of the managed device. As in the repeater module and the interface module remote control, can be implemented schematising transformation of the signal in accordance with what will be described below. Nevertheless, the selection switch may depend on the payload provided by the managed device, which may be significantly more than that of the repeater module.

Fig.7a depicts a first embodiment of a passive module conversion for use in the module repeater module or the remote interface of the managed device. Here, electromagnetic radiation EM1detected by the detecting antenna R10that resonates for receiving the AC signal on the receiving side, and then untied through decoupling capacitor 100 (with a capacitance of 1.5 pF) for receiving the signal 11 of the receiving repeater. It is rectified by the rectifier diode 101, for example, a diode of a Schottky series HSMS285x Agilent Technologies. Thereafter, a smoothing capacitor 103 with a capacitance of 47 pF smooths the rectified output signal to obtain the signal 13 of the excitation switching repeater. A small resistor 102 with a resistance of 10 ohms allows the flow of the minimum current in the module is a passive transformation. The elements of the module 10 repeater that consume current from the source of P10power during operation, presents a resistive load 14.

Fig.7b depicts a graph of the voltage U (in Volts�x), measured parallel to the smoothing capacitor 103, depending on the power ratio in dBm electromagnetic radiation EM1the transmitted transmitting antenna T30. As can be seen from the graph, parallel to the smoothing capacitor 103 can be obtained voltage 1,77 V, when the module 30 remote control provides electromagnetic radiation EM120 dBm. This voltage is sufficient to actuate switch S10MEMS. When this switch S10closed, the load 14 is connected to the source of P10power, and when the switch S10open, the load 14 is disconnected from the source of P10power.

The rectified signal with a higher voltage can be obtained by using an alternative scheme for passive conversion, as shown in Fig.8a. Here, the resonant circuit formed by the coil 105 of the inductance with an inductance of 22 NH in conjunction with decoupling capacitor 100 (1.5 pF). These values are chosen so that the frequency of the signal induced on the receiver side, in fact, exactly the same as on the side of the transmission, using the well-known formula for the resonant circuit:

fc=12πLC ,

where L is the inductance of the coil inductance, and C is the capacitance of the capacitor of the resonant circuit. The values of the components 105, 100 is selected so that the frequency fcthe induced signal is, in fact, was exactly the same as the frequency of the signal generated in the module 30 remote control, in this case 876 MHz. For a resonant circuit follow exactly the same components of the rectification circuit, namely the rectifying diode 101 and a smoothing capacitor 103, as described above in relation to Fig.7a.

This scheme leads to a higher voltage, measured parallel to the smoothing capacitor 103, while requiring lower levels of signal from the transmission. Also in this example, the switch S10can be used MEMS (microelectromechanical systems). As can be seen from the graph in Fig.8b, the voltage of 1.76 In is achieved when the signal strength of only 10 dBm. This is mainly comparable with the values obtained by using the scheme in Fig.7a. This means that the switch S10can reliably and accurately switch even in the presence of a transmitter side of the signal with relatively low power.

There is also the possibility that instead of a battery or a solar cell module of the repeater is connected to a power source. With such options�ante implementation need to switch a higher voltage than those in which can operate a MEMS switch, so can be used a semiconductor switch, as shown in Fig.9a. In this example, a semiconductor switch includes a transistor switch S10such as HBFPO450 Agilent Technologies. Transistor switch S10able to switch heavier loads. In this case, it should be emphasized that the scheme in this example is depicted in simplified form, and that other components and schemes will need to disable the repeater module from a network source P10power or for interfacing low-voltage semiconductor circuits with high-voltage circuit on the side of the device. These points are known to the expert in the field, and their detailed description is not required here.

Fig.9b depicts the corresponding graph of the voltage U (in Volts, solid line) and load current I (in milliamperes, dotted line) depending on the power ratio in dBm. As clearly seen from the graph, even the strength of the signal at 10 dBm sufficient to produce a voltage in 0,915 In parallel to a smoothing capacitor 103 and to ensure the flow of current is 28 mA through the load 14. The obtained values for voltage and current only minimal, in comparison with the values �aluchemie ratio of signal power to 20 dBm (0,937 In, 29 mA) and 30 dBm (0,962 V, 29 mA), respectively.

The decision of the circuit also disables the repeater module 10 from a network source P10power, when the module 10 of the repeater is switched off. When the module 10 of the repeater is turned off, this circuit consumes no current. Only when the module 10 of the repeater is activated, the semiconductor circuit will consume little energy, is small in comparison with the energy of expectation, spending the usual consumer electronics device in idle mode in accordance with modern solutions.

Although the present invention has been disclosed in the form of a number of preferred embodiments, it should be clear that in respect of the described embodiments can be made additional modifications and changes without departing from the scope of the invention. For example, the signal coming into the repeater module or interface module controller may, under certain conditions, be relatively weak. Weak input signal leads to a corresponding low level DC signal, so the signal may be insufficient power for, for example, to actuate the switch. Because of this, weak signal DC at the rectifier output of the repeater module or module int�of RFAS remote control can be amplified in module signal conversion through the corresponding voltage doubler or voltage multiplier to provide a stronger output signal. An example of such a voltage multiplier is a cascade scheme of Villard, containing a set of capacitors and diodes. Possible other alternative scheme of voltage doublers, as is obvious to a specialist in its respective field.
