    Abstract: 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.

    Abstract: Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some cases, an LCom-enabled luminaire configured as described herein may acquire user data from a local computing device and relay it to a server that tracks and analyzes the data to assess statistics for the luminaire's local spatial environment. The disclosed luminaire may receive from a local computing device a request for indoor navigation to a target of interest, such as a remote computing device. The luminaire may relay that request to a downstream luminaire, which delivers the request to the target. The target may respond with data that allows for tracking of its location and indoor navigation thereto, regardless of whether that target is moving or stationary. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, for example, via an optical interface or other wired or wireless communication.

    Abstract: Techniques are disclosed for identifying and controlling light-based communication (LCom)-enabled luminaires. In some cases, the techniques include a luminaire communicating its ID to a computing device via one or more LCom signals. In some cases, a user may be able to aim a rear-facing camera of a smartphone at the luminaire desired to be controlled. Once the luminaire is in the field of view of the camera, the ID of the luminaire can be determined using one or more LCom signals received from the luminaire. The ID of the luminaire may be, for example, its internet protocol (IP) address or media access control (MAC) address or another unique identifier. Once a luminaire has been identified, commands can be issued to the luminaire to adjust one or more characteristics of the light output, such as changing the dimming percentage of the light output.

    Abstract: Techniques are disclosed for projecting visible cues to assist with light-based communication (LCom), the visible cues referred to herein as visual hotspots. The visual hotspots can be projected, for example, using a luminaire that may be LCom-enabled. The visual hotspots may be projected onto the floor of an area including an LCom system. The visual hotspots can be used for numerous benefits, including alerting a potential user that LCom is available, educating the user about LCom technology, and assisting the user in using the LCom signals available in the area. The visual hotspots may include images, symbols, cues, characters (e.g., letters, words, numbers, etc.), indicators, logos, or any other suitable content. In some cases, the visual hotspots may be interactive, such that a user can scan the hotspot to cause an action to occur (e.g., launch an application or website).

    Abstract: Techniques are disclosed for augmenting global positioning system (GPS)-based navigation via light-based communication (LCom). In accordance with some embodiments, a light-sensing device, such as a camera or an ambient light sensor configured as described herein, may be used to detect an LCom signal transmitted by a local LCom-enabled solid-state luminaire. The LCom signal may include data about the location of the transmitting luminaire, and in some cases that location data may be used, for example, in computing the amount of time that it would take to navigate indoors to the luminaire's location. In some instances, GPS data also may be considered to calculate the total trip duration for an entire trip, including time spent indoors and outdoors. In some other cases, the location data and, if available, GPS data may be used, for example, in computing an automotive navigation route.

    Abstract: A power supply system providing communication from a master module to at least one slave module via transients, to alter operation of a load, is provided. The master module output a supply voltage that is either a normal supply voltage or a reduced supply voltage. The outputted supply voltage depends on input corresponding to a communication to be sent to the slave module to alter operation of the load of the slave module. The slave module receives the supply voltage and interprets the received supply voltage, which may vary between the normal and reduced supply voltages, to determine what the communication from the master module is. The slave module then uses information from the communication to appropriately alter operation of its load.
