The prior art INVENTIONS

Modern lighting systems that include multiple light sources, selection and management of light sources is typically carried out using stationary devices, such as wall panels, containing the switches. Switches are used to control light sources, for example, to enable/disable them or reduce their brightness. In the case when the user wants to change any of the lighting, the user must return to the wall panel. Of course, the user needs to know which switch controls which light source. However, often the user does not have this information, so as switches or light sources are not labeled. This situation is particularly problematic in the case of multiple light sources and multiple switches, where the switch that controls the desired light source, it is found by trial and error.

Recent developments have created a remote driven the I, emitting a directional beam selection, suitable for selection and control of light sources. However, the use of remote control devices creates the danger of random selection device (e.g., light source) that is different from the desired device. So you need to find a compromise between the simplicity of the device selection (preferring wide beam selection from a remote control and prevention of the danger of selecting multiple devices (preferring narrow beam selection from a remote control).

US2003/0107888 discloses a remotely operated modular lighting system that uses directional wireless remote control for selective adjustment and programming of the individual lighting modules. Individual lighting modules can be selected for adjustment by instant instructions remote control for lighting module that you want to adjust. Further adjustment can be performed without guidance on the lamp, allowing you to focus operators on the illuminated object. Adjustments may include on/off, brightness, color change and guidance of light from the light source (i.e. the adjustment of the light distribution). If the lighting modules are arranged densely, so many mo is Uli selected directional beam selection the remote control contains the additional feature that allows the user to cycle to move through selected lamps by repeatedly pressing the select button until the light on the right of the lamp module.

However, it may be desirable to provide an improved method of selecting at least one managed device, such as a light source from the set of managed devices.

The INVENTION

In accordance with an aspect of the invention, the aforementioned at least partially performed using a method for selecting at least one of the multiple managed devices, in which each of the managed devices is adapted to transmit a distinguishable signal. The method includes the steps of receiving signals from multiple managed devices through multiple receiving modules contained in the control device, such as a remote control device, where each receiving module separately detects the contribution of signals; determining the width and angle of incidence for each of the signals using correlation between the different contributions of the signal; comparing the width and angle of incidence for each of the signals with a set of pre-established criteria and selecting at least one of the multiple managed devices, it is best suitable for the subsequent set of pre-established criteria.

Unpublished applicant application PCT/IB2009/052363, fully incorporated by reference, discloses a method for selecting a managed device from the set of managed devices by: signal transmission from each of the managed devices in the remote control device; determining the angular deviation between the remote control device and each of the managed devices on the basis of the angle signal which is accepted by the managed device; and selecting the controlled device based on the angular deviation. However, when the number of controllable devices is placed in a structure, for example, in the bathroom, the signals may be reflected, for example, from the walls. So sometimes the signals are not only taken control device for line-of-sight to the managed devices, but also from other areas because of the mirror and/or lambertucci reflections of signals. Thus, if the control device selects the controlled device based on the angular deviation between the control device and various controllable devices, the control device may specify in the direction, which corresponds to the mirror reflection on the wall, while the controller "thinks" that it refers to a managed device from which the alarm came from. For example, if is the first controlled device is placed adjacent to the reflection signal, outgoing from the second managed device, then a situation may arise when the user specifies the control device to the first controlled device and the control device randomly selects a second device, since the angle between the control device and the reflection associated with the second managed device is less than the angle between the control device and the signal from the first device.

The present invention is based on the understanding that when the signal is reflected on a surface such as a wall, it will affect the width of the signal (which is perceived by the receiver in the control unit). In particular, the width will increase after reflection. Studies of reflections of different types of light sources on the walls by shooting the image of the light source with the camera (that is, when light is taken along the line-of-sight), and then capture an image of the reflection of the same light source. These studies showed that reflect, as a rule, have a width, component of 40° in diameter or more, where the width may be measured, for example, as the angular distance between the points where the intensity falls to 50% relative to the maximum or full width at half maximum (FWHM), or, if the light distribution corresponds to a Gaussian distribution width can be described by the standard deviation of the latter. This is usually true to indicate locations where the user is not too close (>1 m) to the wall to which it points. On the other hand, these light sources typically have a width equal to only a few degrees or less in diameter at distances of >0.5 m (i.e. in the field of view of the control device, the light source forms an angle only a few degrees and, accordingly, has a small width). Thus, the width of the reflected signal will typically be much wider than a similar signal received directly from the light source (i.e. the trajectory line-of-sight). Accordingly, given the breadth of received signals, it is possible to suppress reflection in the attitude of the device.

The signals may be, for example, optical signals (e.g., infrared, radio frequency signals (e.g., 60 GHz) or ultrasonic (>20 kHz). Preferably, the signals are sufficiently different from the background noise, using, for example, a pseudo-random number sequence. In addition, the signals may contain orthogonal or quasiorthogonal identifying codes, which provide the possibility of using identifying codes with special properties correlation to distinguish between signals originating from different managed devices through this with Krasa or eliminating interference. Additionally, when a managed device is a lamp or a lamp that contains a set of light-emitting elements, the light emitted from the light-emitting elements, can be used as a signal, thereby eliminating the need for a separate transmitter for these signals.

Comparison with a set of pre-defined criteria may be such that the selected controlled device, the signal having a small width. For example, comparison with a set of pre-defined criteria may be such that is not selectable no controlled device having a signal with a width exceeding the predetermined threshold value. Using a suitable threshold value, it is possible to exclude any managed device with the signal that was recorded. Because of this it is possible to identify the managed devices that are actually in the direction of the guidance control device. You can then choose at least one of these managed devices in accordance with one or more additional criteria. The threshold value may be set, for example, for a managed device having a signal width, which exceeds 10°, or preferably a width which exceeds 20°, for example of a width exceeding 40°.

In the accordance with the embodiment, predetermined threshold value may be a function of the signal level of the received signal, or in other words, the comparison with a set of pre-established criteria may prefer a managed device having a signal with a high signal level. The advantage is that the threshold value can be adapted to the type of signal transmitted by the managed device. This gives the possibility to use the method for signals that are relatively wide (non-signal). An example of such a signal would be light radiated "wall lamp".

Comparison with a set of pre-defined criteria may be preferable to choose a managed device having a signal with a small angle of incidence. For example, the criterion may be that the selected controlled device, which has the signal with the smallest angle of incidence (the number of managed devices, which are selectable). The advantage is that the measured angles of incidence can be made insensitive to the amplitude of the signals. Therefore, the attenuation of the signal (signals), for example, by obstacles such as lamp shades that do not harm the company's ability to obtain appropriate information about the angles.

In accordance with the embodiment, each of the receiving modules mo is et to include a photodiode. Alternatively, receiver modules can be pixels in the schemes imaging, for example, in the camera, such as a sensor based on CCD (charge coupled device) or a sensor based on CMOS (complementary structure of metal-oxide-semiconductor). This allows to determine the angle and width using simple methods of object recognition.

Comparison with a set of pre-defined criteria may be such that is not select any managed device that has a signal, for which at least one of the inputs of the signal below a predetermined noise threshold. This can suppress the influence of noise sources present in the system, such as shot noise in the photodiodes, thermal noise in circuits, amplifying the signal from the photodiode and the optical or radio frequency noise in the room.

In accordance with the embodiment, the width and/or angle of incidence of the signal can be determined by matching the target distribution (e.g., Gaussian distribution), parameterized by the angle offset and width (and optionally amplitude), with inputs of the signal. This enables you to determine the width and the angle of incidence from a small number (e.g. three) different contributions of the signal. Further discussion regarding the mapping is given below.

In soo is according to another aspect of the invention, provided a control device for use with a variety of managed devices, where each of the managed devices is adapted to transmit a distinguishable signal, thus the control device includes: multiple receiving modules, where each receiving module adapted for separate detection of the contribution of the signals; and a control unit configured to perform the above-described method for selecting at least one of the multiple managed devices. This aspect of the invention provides similar advantages as discussed above with respect to the previous aspect of the invention. In addition, control device in accordance with the present invention may preferably be incorporated into the system, optionally containing many managed devices adapted to transmit a distinguishable signal.

In accordance with one embodiment, the managed device may be light sources such as lamps or luminaires containing one or more light-emitting elements. In this embodiment, the visible signal can be transmitted primarily through the use of light-emitting elements. This eliminates the need for a separate transmitter.

In accordance with another aspect of the invention, provided is a procedure for use in the system, containing the controller and the number of controllable devices, where the control device is adapted to transmit a signal containing many contributions audible signal. The method includes the steps of receiving the above signal by receivers placed in the set of managed devices; determining for each managed device that has received the signal, the width and angle of incidence of a received signal using a correlation between the contributions of distinct signal; comparing the width and angle of incidence for received signals with a set of pre-established criteria and selecting at least one of the multiple managed devices having signal that best fits a set of pre-established criteria. A set of pre-established criteria may be similar to the criteria discussed above. This aspect of the invention corresponds to the preceding aspects and provides similar advantages. However, the idea is modified so that the control device is provided with means to transmit a signal containing many contributions of the signal, and this signal may be received by the receiver in each managed device, where the width and the angle of incidence of a received signal can be determined controllable devices or in conjunction with a control device. In addition, this is t aspect is included in the basic idea of the invention, that is the definition of the width and angle of incidence of a received signal and comparing the width and angle with a set of pre-established criteria.

In accordance with the embodiment, the method may further comprise the step of transmitting the control device width and angle of incidence for later use in selecting at least one managed device. This means that the calculation of the angle and/or width may occur in managed devices.

In accordance with another embodiment, a method, respectively, may further comprise the step of transmitting the control device information about the contributions of distinct signal for subsequent use in determining the width and angle of incidence of a received signal. The advantage of this is that in a typical application for lighting control device can be configured with the ability to have more computing power than the managed device.

This method may preferably be used in a system with a control device and a variety of managed devices, where the control device is adapted to transmit a signal containing many contributions audible signal.

Additional characteristics and advantages of the present invention will become apparent when studying the research Institute of the attached claims and the following description. Qualified understood that the various features of the present invention can be combined to create embodiments other than those described below, without deviating from the scope of the present invention.

DETAILED DESCRIPTION

The present invention hereinafter will be described yatsa more fully with reference to the accompanying drawings, showing preferred in the present embodiments of the invention. However, this invention can be implemented in many different forms and should not be construed as limited options for implementation set forth herein; rather, these embodiments of provided for completeness and complete, and fully convey the scope of the invention to a qualified specialist. Throughout the text the same item numbers refer to identical elements.

Referring now to the drawings and to figures 1a-b, in particular, the depicted system 100, is placed in a space, for example in the bathroom. The system 100 includes a control device 110, such as a remote control, and three managed devices 121-123 managed lamps.

Managed lamps 121-123 here are spotlights, comprising a set of light-emitting elements (for example, one or more light-emitting diodes) which has a capability to emit light to illuminate the room. The first 121 and second 122 lamps are lamps directional light, is arranged to provide direct illumination of the room, while a third lamp 123 is illuminated, made with the possibility of providing indirect lighting PU is eating the reflection of light on the ceiling, as indicated by the reflection 123'. All lamps 121-123 emit light with the same (source) wide. However, the reflection 123' on the ceiling wider than other lamps 121, 122, from the point of view of the remote control 110 remote control.

Additionally, each lamp 121-123 supplied by the control unit in electrical connection with the light-emitting elements of the respective lamps 121-123. Each of the control units in the lamps 121-123 is configured to modulate the light emitted to the contained individual identification code, thereby allowing to distinguish between light from different lamps 121-123. Identifying codes preferably are selected so that they are (quasi)orthogonal relative to each other to minimize interference between the modulated light from different lamps 121-123.

The remote control 110 remote control also contains a control unit with electrical connection to the receiver 112. The receiver 112 includes five (preferably identical) modules 112a-e reception, here are photodiodes (fotopriemami diodes). Photodiodes 112a-e are placed so that there is a single photodiode a in the center and four others photodiode 112b-e. The Central photodiode a preferably points in the direction 113 specifying device 110 remote control (i.e., the direction of the AI, in which the user moves the remote control) while the surrounding photodiodes 112b-e preferably placed with a constant angular offset. Here, each of the surrounding photodiodes 112b-e points in the direction that deviates from the direction 113 specifying device 110 remote control on the angle ∆φ. The angle ∆φ can vary, for example, due to the geometry of the photodiodes and their placement in the receiver 112, but is typically in the range from 10° to 15°. Here ∆φ is approximately 15°. In addition, each photodiode 112a-e has a respective field of view (FOV), i.e. the angular range where it can detect incident light. For each photodiode 112a-e may be provided with angular filter to limit the field of view. The filter here is achieved by placing the tube 114 on top of the photodiode 112a-e. However, the angular characteristics of the photodiodes 112a-e can also be limited by using, for example, lenses or specially created photodiodes. Characteristics of a typical filter is illustrated in Fig.2. As illustrated, the field of view of each of the photodiodes is approximately ±15° from the Central axis of the photodiode.

The system 100 will now be described with reference to the block diagram of the algorithm of Fig.3. To provide a clear and concise description, width and the angle of incidence of any signals here defined, is alauda only for the first (horizontal) plane, using the Central a, left 112b and right 112c photodiodes remote control. A possible generalization to three dimensions will be discussed later.

During operation, each of the controllable lights 121-123 transmits a signal in the form of modulated light containing an identifying code for the corresponding lamp 121-123. The signals are then received at step 301 receiver 112 in the remote control 110 remote control. The control unit in the device 110 remote control distinguishes between signals from different lamps 121-123 using identifying codes for each signal determines the contribution of the signal for each of the photodiodes 112a-c. The contribution of the signal is indicated by the photocurrent from the associated photodiode 112a-c.

The contributions of the signal to the signal received from the first lamp 121, schematically illustrated in Fig.4a. Here the contributions of the signal detected by the Central a, left 112b and right 112c photodiodes, denoted f0f-and f+respectively. Thus, the photodiode a samples the intensity distribution at φ=0°, photodiode 112b selects the intensity distribution at φ=-Δφ, and photodiode 112c samples the intensity distribution at φ=+Δφ. Additionally Fig.4b shows the contributions of the signal to the signal received from the second lamp 122, while Fig.4c shows the contributions of the signal of the La signal, taken from the third lamp 123 (through reflection 123').

The control unit in the remote control 110 remote control then determines the width and the angle of incidence for each signal at step 302, using the correlation between the different contributions to the signal. Here this is achieved by mapping the Gaussian distributioninput signal associated with the signal.

Thus, for each signal is obtained system of equations:

This system of equations can now be solved for σ, φ0and A in terms of the known/measured numbers {Δφ, f0f-f+}.

Thus, the standard deviationspecifies the width of the signal centerspecifies the angle of incidence of the signal, whereas a is the signal amplitude. The angle of incidence is the angle between the direction of guidance control device and the direction of the incident signal.

Gaussian distribution 400A corresponding to the contributions of the signal f0f-and f+associated with the signal from the first lamp 121, schematically illustrated in Fig.4a. Similarly Gaussian distribution 400b corresponding to the contributions of the signal f0f-the f +associated with the signal from the second lamp 122, schematically illustrated in Fig.4b, whereas the Gaussian distribution 400c, corresponding to the contributions of the signal f0f-and f+associated with the signal from the third lamp 123 (through reflection 123'), schematically illustrated in Fig.4c. Specialist in the art may note that the best match and the best estimates can be achieved by using a larger number of photodiodes (and, correspondingly, a larger number of inputs signal).

On stage, 303-305 the control unit compares the width and the angle of incidence for each of the signals with a set of pre-established criteria.

At step 303, the first pre-determined criterion may be used to exclude lamps having a signal with a width that exceeds a predetermined threshold value. For example, the predetermined threshold may be set for the exception of lamps for which the received signal has the luminous intensity distribution with a standard deviation of σ greater than 20°. As is illustrated in Fig.4a-c, the signals received from the first 121 and second 122 lamps have a relatively small width (for example, σ≈10°), whereas the signal received from the third lamp 123 through which tragedia 123', much wider (e.g., σ≈60°). Thus, the third lamp 123 is excluded, and only the lamp 121 and the lamp 122 will remain selected.

At step 304, a second pre-determined criterion is used to determine which of the lamps 121-123 (among selectable lamps 121-122) is the signal with the smallest angle of incidence. As indicated in Fig.4a-b, the angle of incidence (for example, φ0≈10°) of the signal received from the first lamp 121, a smaller angle of incidence (φ0≈30°) of the signal received from the second lamp 122, and accordingly the control unit in the remote control 110 remote control will select the first lamp 121 at step 304. Once selected controlled lamp, remote control can be used for lighting control in accordance with methods well-known in this technical field.

It can be noted that the angle of incidence (for example, φ0≈5°) of the signal received from the third lamp 123 through reflection in 123', is less than the angle of incidence (φ0≈10°) for the signal received from the first lamp 121. Thus, if the selection was based only on the angle of incidence of the signal, the remote control would choose the third lamp 123 instead of the first lamp 121.

It is obvious that instead of the exception of lamps with a signal with a large width, the stage of the 303 you can use the function which is configured so that it is less likely to be selected lamp having a signal with a large width (and/or with a large angle of incidence). For example, can be used in the objective function, where the angle of incidence is weighted based on the width of the signal, i.e. the objective function value is greater for a larger angle of incidence of the signal and for the greater width of the signal. Then we can choose a lamp that has a signal with the lowest value of the target function.

Although the width and the angle of incidence of the signal is defined only in the first (horizontal) plane, using the Central a, left 112b and right 112c of the photodiodes in the remote control 110 remote control, it is obvious that this method can be extended to three dimensions. For example, you can define the width and the angle of incidence of the signal in the second (vertical) plane, using the Central a, top 112d and lower e photodiodes, and then estimate the angle and width of the signal in three dimensions as:

andwhere

- the standard deviation in the horizontal plane;

- the standard deviation in the vertical plane;

- the angle of incidence in the horizontal plane and

- the angle of incidence in the vertical is locoste.

In addition, since the Gaussian distribution will tend to overestimate the width and the angle of incidence of about 25-50% for signals with a large angle of incidence, can be used for correction. The correction may vary (for example, photodiodes used), but an example of a correction would be,where α is some constant, for example α=30°.

In the above-described procedure, the estimated width is usually dependent on the intrinsic width of the signal from the lamp and the field of view of the photodiodes. This can complicate the estimation of the true width for signals, where the estimated standard deviationless than or equal field of view (FOV) of the photodiodes.

Therefore, the field of view of the photodiodes must be sufficiently small, it is preferable that each photodiode had a FOV of less than 15°, or preferably less than 10°. On the other hand, a very small field of view makes it difficult for "discovery" lamp for the user (that is a fairly accurate indication of the lamp). This compromise can be achieved by adding more photodiodes. Thus, when designing a receiver 112 may apply the following rule:

the required pointing accuracy of personwhere

N denotes the number of photodiodes; and

FOV - field of view on the I of each individual photodiode.

For some type of lights emitted light may have a relatively large width (without reflection). An example of such a lamp would be "wall lamp". This lamp, which casts a wide picture on the wall for accent lighting. For example, wall lamp width of two meters remote control can perceive width σ=45° at a distance of two meters from the wall, and a width of σ=6° at a distance of ten meters from the wall. That is, at a short distance (for example, from 1 to 2 meters) width of light from the wall lamp is very large, as well as reflection. Therefore, in order to distinguish the lamp from the reflection, you can not rely on constant predetermined threshold value.

Wall lamp from the reflection differs (when the perceived width of wall lamp large), that its capacity is significantly higher than that of reflection. Thus, using dependent power threshold value, wall lamp can be distinguished from reflection. An example of such a threshold value iswhere Ti- the threshold value for the lamp i, Pi- properly normalized power for the signal received from the lamp i and FOV - field of view of the individual photodiode. In a typical applied and the threshold value may vary between 15° and 50°.

It can be noted that the threshold value ofhas the desired property in two modes. First, when the remote control is located at a relatively close distance r from the lamp, the power of the received signal is large and the measured width is greater than the field of view of the photodiodes in the receiver. In this mode it is assumed that the measured width increases as 1/r, and the signal strength as 1/r2where- width of the signal received from the lamp i. Secondly, when the remote control is at a large distance r from the lamp, the power of the received signal is small and the measured width of approximately constant, because it concentrates in the field of view of the receiver (each measured light distribution at least as wide as the field of view of the receiver), that is,where- width of the signal received from the lamp i.

Moreover, if desired, can be used by one or more pre-established criteria. For example, can be pre-determined noise threshold, so that you can depart deposits of the signal below a predetermined noise threshold (e.g., three times the standard deviation of the noise in zavisimost and the desired probability of false positives). This suppresses the influence of noise sources present in the system, such as shot noise in the photodiodes, thermal noise in circuits, amplifying the signal from the photodiode and the optical or radio frequency noise in the room.

Other predetermined criteria may be predefined threshold angle. Some lamps can create a weaker signal because they are further away or more attenuated shade. This implies that the area in which the "weaker" fixtures create a photocurrent above a predetermined noise threshold (and thus the area in which they could potentially choose), significantly less than for "stronger" lamps. To limit this illogical behavior, selection may exclude any lamp that has the signal from the intended angle of incidence φ0that exceeds a predetermined threshold value (for example, 25°).

Fig.5 illustrates an alternate embodiment of the invention, where the idea is modified so that the remote control is supplied with means to transmit a signal containing many contributions of the signal, and this signal may be received by the receiver in each managed device, where the width and the angle of incidence of a received signal can be defined managed in what tristani or together with the control device.

Such a system can be achieved by replacing fotopriemami diodes in the remote control in previous versions of the implementation fotoperiodismo diodes 512a-e and placement of the receiver, which can be a single photopreneur diode, each of the multiple managed devices (which may be lamps). When you work every photoparade diode 512a-e in the remote control transmits the contribution of distinct signal, where it is preferable that all deposits of the signal have the same effect. Contributions audible signal can be considered as a set of subsignals forming a signal which is received photopreneur diode in each managed device. Each managed device can then determine the width and the angle of incidence of a received signal based on the strength of the contributions of distinct signal by mapping a Gaussian or other distribution input signal, where the standard deviation σ from the Gaussian distribution specifies the width, and the center φ0specifies the angle of incidence. This can be achieved in a similar way to that described above. Information about the width and angle of incidence can then be passed to the control device, which can choose a managed device that best meets a set of pre-established criteria, a pre-installed CR the criteria can be similar to those described above. Alternatively, the managed device may transmit the measured contributions of distinct signal control device, where the latter determines the width and the angle of incidence of a received signal for each of the managed devices by mapping (for each managed device) with Gaussian or other distribution. It may be noted that this implementation is based on the same principle as described above, an implementation option, that is the definition of the width and angle of incidence of a received signal and comparing the width and angle with a set of pre-established criteria to choose a managed lamp.

Although the invention is described with reference to its illustrating certain embodiments of many different changes, modifications, etc. will be obvious to a person skilled in the art. Variations of the disclosed embodiments can be understood and carried out by qualified specialist in the practice of the claimed invention, from a study of the drawings, the disclosure and the accompanying claims. For example, instead of using a signal in the form of modulated light transmitted by the light-emitting elements in a controlled lamp, can be used to separate the signal transmitter for signal transmission. This is eredeti can pass, for example, optical signals (such as infrared (IR) or radio frequency (RF) signals. If the transmitter is a radio frequency transmitter, each receiver module remote control is a radio frequency detector. The advantage of this is that you can avoid any flicker perceived by the user. In addition, the managed device does not necessarily lamps, and can provide an alternative device, such as tents, switches or the doors. In addition, the remote control device can be a single handheld device, or a combination of handheld devices and the Central controller. In addition, there may be used an alternative configuration of the receiver in the remote control. It is also possible to use other methods to estimate the width and angle of incidence of the signal. For example, if it is assumed that the intensity distribution of the received signal is approximately circular symmetric, it is possible to use a directional receiver with a single Central receiver module and others receiving modules (for example, three modules are placed at the corners of an equilateral triangle, or 2 or more receiving module with consistently large fields of view, oriented in the same healthy lifestyles the NII). Discovered deposits of the signal then can be mapped only in the radial direction with the target distribution in the form of three concentric rings. In addition, receiver modules can have different fields of view. The contributions of the signal can also be viewed as a sample of (unnormalized) probability distribution in which the mean and standard deviation of this distribution would give estimates of the incidence angle and the width of the signal. Receiver modules can also be the pixel circuits in the imaging, for example, in the camera, such as a sensor based on CCD (charge coupled device) or a sensor based on CMOS (complementary structure of metal-oxide-semiconductor). This allows you to determine the width and the angle of incidence using methods of object recognition.

In addition, in the claims the word "comprising" does not exclude other elements or steps and the sign of the singular does not exclude the set.
