Abstract: 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.

Abstract: 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.

Abstract: 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.
