摘要： Techniques and architecture are disclosed for mobile transport systems configured to determine vehicle positions within an area using light-based communication signals. The system includes a plurality of luminaires located in an area and configured to transmit luminaire position data recognizable by a sensor disposed on a vehicle. The sensor receives an image of a luminaire including a light-based communication signal encoded with luminaire position data. Luminaire position data can be combined with luminaire layout information to determine a known location of the luminaire. A vehicle position relative to the known luminaire location can be determined based on mathematical relationships. Vehicle orientation relative to the area can be determined based an asymmetric fiducial pattern or multiple known luminaire locations. The system can combine a vehicle position relative to a known luminaire location with vehicle orientation relative to the area to determine a vehicle position relative to the area.

摘要： Techniques are disclosed for measuring an amount of flicker produced by a light source. In one embodiment, a flicker measuring device includes a photo sensor to measure the amount of light produced by the light source, a dedicated processor to receive and process data from the photo sensor, a memory bus coupled to an analog-to-digital converter (ADC) and to a first memory, and a direct memory access (DMA) bus coupled to the ADC and to a second memory. In another embodiment, a flicker measuring system uses a light sensor, an associated circuit and a portable computing device (PCD), such as a smart phone, to measure an amount of flicker produced by a light source by sending an electrical signal from the light source and associated circuit via an audio output to an audio sub-system of the PCD, so that the PCD may calculate the flicker value.

摘要： Techniques are disclosed for detecting stationary presence using IR sensor array. A number of IR images may be captured. Of the IR images captured by the IR sensor array certain pixels can be identified as causing false triggers. These pixels can be identified and filtered to be ignored. The non-filtered pixels of IR images may be averaged over various time intervals to calculate a number of average IR frames. The difference between these average IR frames provides a delta frame. A mask frame may be calculated as the summation of delta frames over time, and the value of the mask frame may be used to detect a stationary human presence even when no delta value is calculated. Alternatively, the mask frame may be used to calculate a background frame that represents the IR signature of stationary or cyclical objects within the scanned area that are not intended to trigger the presence detection system. A stationary presence may be determined by subtracting the background frame from a current average IR frame.

摘要： Various embodiments include a voltage adjusting block (VAB) coupled to a light emitting diode (LED) string. The VAB includes a first switch having a first lead connected to a voltage input, and having a second lead, the first switch having a controllable duty cycle, a first diode having a cathode connected to the second lead of the first switch, and having an anode, a first inductor having a first lead connected to the cathode of the first diode, and having a second lead, and a first capacitor having a first lead connected to the anode of the first diode and having a second lead connected to the second lead of the first inductor. The VAB may provide a variable voltage across the anode of the first diode and the second lead of the first capacitor dependent upon a number of LEDs in the LED string being turned on.

摘要： Techniques are disclosed for decoding light based communication (LBC) messages transmitted between a transmitter device and a receiver device. The receiver device includes a processor that executes a process to decode a received LBC message. The processor determines a moving average and removes the moving average to provide a second digital message (with the moving average removed), to account for any noises or interferences. The moving average may be determined using a length-preserving moving average. The peak location in the second digital message is identified and used as a start position for synchronization when the peak location is above the threshold. Sampling points are derived, and logical maximum and minimum values (1's and 0's) are assigned to one or more of the sampling points. The logical values are decoded to generate a decoded sequence of data representative of the received LBC message.

摘要： Optical components for lighting devices and lighting devices including such components are described. In some embodiments the optical components are in the form of a lens that alter the distribution of light produced by a lighting fixture. In some embodiments, the lenses are in the form of a downlight to wallwash lens which, when placed in a downlight fixture, convert the light distribution to that of a wallwash fixture, e.g., causing the downlight to produce an off-axis light distribution, without changing the fixture. The lens includes a body with a light source facing side and an opposite room facing side having two optically active regions, each including structures that redirect a portion of light received through the light source facing side and incident thereon. The first region includes structures that redirect, via refraction, and the second region includes structures that redirect, in part via total internal reflection.

摘要： Aspects of the present disclosure include methods and systems for the automated commissioning of a network of electronic devices. The locations of large systems of installed electronic devices equipped with wireless communication modules, such as luminaires, light switches, and occupancy sensors, can be rapidly determined by using inter-device distance measurements to calculate the location coordinates of the devices. Increased confidence in the calculated location coordinates can be achieved by comparing the calculated values to an installation plan and assigning the IDs of the specific devices to the location coordinates in the installation plan.
