摘要： 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).

摘要： Techniques are disclosed for detecting stationary presence using IR sensor data. A number of IR images may be captured based on IR sensor data and these 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： Techniques are disclosed for coding light-based communication (LCom) data in a manner that allows for detection thereof, for example, via a standard low-speed (e.g., 30 frames per second) smartphone camera. In accordance with some embodiments, the disclosed techniques can be used, for example, in encoding and decoding LCom data in a manner that: (1) prevents or otherwise minimizes perceivable flicker of the light output by a transmitting LCom-enabled luminaire; and/or (2) avoids or otherwise reduces a need for additional, specialized receiver hardware at the receiver computing device (200) including the camera. In some cases, the disclosed techniques can be used, for example, to enhance the baud rate between a transmitting LCom-enabled luminaire and a receiver device.

摘要： 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.

摘要： Systems and methods to change a light output level using adaptive frequency control are provided. A switched mode power converter is configured to switch output current to a light emitting diode (LED) module, which includes an LED lighting element, at a switching frequency. Control circuitry is configured to receive a dimming control input that corresponding to a desired light output level of the LED module. The control circuitry is also configured to provide a pulse width modulation (PWM) output configured to pulse width modulate the output current, the PWM output having a pulse width, a PWM frequency, and a PWM period corresponding to the PWM frequency. The control circuitry is also configured to adjust at least one of the PWM period and the switching period in response to a change in the dimming control input, such that a light output level of the LED module is appropriately changed.

摘要： 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.
