Abstract: Techniques are described herein for to improving optical wireless communications based on mobility patterns. In various embodiments, one or more mobility patterns observed in an area over time may be determined (302). The area may be illuminated by one or more lighting units (102) configured to transmit information using optical wireless communications (“OWC”). An applicable mobility pattern may be selected (308) from the one or more mobility patterns. Based on the selected mobility pattern, usage in the area of a plurality of OWC-based mobile apps (230) may be predicted (310). One or more OWC resources of at least one of the one or more lighting units may be allocated (312) for transmission of data to one or more of the plurality of OWC-based mobile apps operating on one or more mobile devices operated within the area. In various embodiments, the allocating may be based at least in part on the predicted usage.

Abstract: A system and methods are provided for group lighting interaction. A lighting infrastructure includes a plurality of simultaneously and independently controllable lighting devices. As various users request access to control the lighting infrastructure, the system and methods involve dynamically partitioning the lighting devices into subsets and then allocating each subset to a corresponding requesting user. The dynamic partitioning may be based on each user's respective location or the time each user requested access to control the lighting infrastructure.

Abstract: A system and methods are provided for an emergency support system installed in light poles. Each emergency support system continuously monitors for motion to identify anomalous motion activity on a local level. In response, a notification is sent to a base station that provides a global analysis by collecting motion data from nearby emergency support systems. An alert is generated if anomalous motion is detected across multiple emergency support systems.

Abstract: The described embodiments relate to systems, methods, and apparatuses for controlling energy resources available to micro-grids of a city based on mobility patterns of people moving within the micro-grids. The mobility patterns can be identified using a network of sensors within each micro-grid for collecting data related to the movement of people within the micro-grids. The mobility patterns can be used to estimate energy demand for each micro-grid and prioritize the energy demands to determine the energy resources that would be suitable for supplying power to each micro-grid. This allows for micro-grids to dynamically and efficiently change their power sources according to predictions about the movement of people within the micro-grids.

Abstract: A fault detection system (100) for detecting faulty devices among a first plurality of serviceable devices (200) is provided. The serviceable devices have a wireless transmitter (210) arranged to periodically transmit a wireless signal (230) that encodes a device identifier. Mobile devices have a receiver (310) arranged to receive the wireless signal of a serviceable device within the transmission range, and to obtain the device identifier from the wireless signal. A fault detector (400) is arranged to detect faulty devices by selecting device identifiers in the plurality of device identifiers for which no device identifier was received in a time period.

Abstract: A system and methods are provided for an immersive group lighting interaction. A lighting infrastructure includes a plurality of independently controllable lighting devices. According to an embodiment, users may be granted access to control at least a portion of the lighting infrastructure. Rather than requiring the user to manually control the lighting infrastructure using, for example, the touch screen, a sensor associated with the user's mobile device may track the user. The sensor data may be classified and then mapped to a corresponding control instruction to control the lighting infrastructure. In another embodiment, a computing system receives sensor classifications from multiple users. If a threshold amount of a type of classification is received, the computing system controls a lighting infrastructure according to that type of classification.

Abstract: A system and method for determining a number of occupants at a location using multiple modalities. The method includes gathering a first data set with a motion sensor of the lighting system. A second data set is gathered with a transceiver of an RF subsystem. First and second estimates are calculated from the second data set using first and second algorithms. The first estimate and the second estimate are fused to create a fused occupant estimate. The first algorithm, the second algorithm, or both the first algorithm and the second algorithm are trained by inputting the second occupant estimate and/or the second set of data to recalibrate parameters of the first algorithm and/or inputting the first occupant estimate and/or the first set of data to recalibrate parameters during training of the second algorithm. A building control system can operated in response to the fused occupant estimate.
