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: Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some embodiments, an LCom-enabled luminaire configured as described herein may include or have access to a sensor configured to detect a hazardous condition. In response to detection of a hazard, the LCom-enabled luminaire may adjust its light output, transmit an LCom signal, or both, in accordance with some embodiments. A given LCom signal may include data that may be utilized by a recipient computing device, for example, in providing emergency evacuation routing or other indoor navigation with hazard avoidance, emergency assistance, or both. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, in accordance with some embodiments, via an optical interface or other wired or wireless communication means. In some cases, the network may include a luminaire that is not LCom-enabled yet still configured for inter-luminaire communication.

Abstract: Phase angle detection techniques for phase-cut dimming lighting circuitry are disclosed. A phase-cut lighting driver circuit may include galvanic isolation circuitry having a primary and secondary side. The phase angle information of a phase-cut signal may be detected on the secondary side of the driver circuitry, and a microcontroller can create a dimming signal that adjusts the driver output power according to the phase angle information. In some embodiments, the phase angle detection techniques may be utilized to control the output of lighting driver circuitry, such as a phase-cut dimming LED driver.

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 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 provided for bi-directional communication between a power supply and one or more light engines (and/or other lighting system components) via the existing power lines so that no additional communication wires are needed. In particular, the power supply can transmit information by modulating its output (voltage or current) and the light engine (or other lighting componentry, such as a sensor) can communicate back by modulating how much power it draws from the power supply. Any suitable type of modulation scheme can be used, and a master-slave arrangement can be used to control the bi-directional communication if so desired, so as to avoid multiple devices communicating over the power line communication channel at the same time. Other embodiments allow a multiple simultaneous communications over the power line communication channel.
