Abstract: A system, method and portable device are provided in which rolling shutter images containing visible light communication (VLC) transmissions from one or more light sources carrying information data in dark or low surrounding lighting in an indoor or outdoor setting are captured. The captured rolling shutter images are analyzed to determine whether the modulated visible light output from the light devices is a predetermined size within the captured rolling shutter image. When the modulated visible light output is not the predetermined size, adjustments are made to settings of the image sensor to scatter, defocus or overexpose the image to cause the modulated visible light output in a new captured rolling shutter image to be at least the predetermined size. The modulated visible light output of the predetermined size or larger is decoded to provide information data for a communication application.

Abstract: A device uses gated retro-reflectors to transmit uplink data in a visible light communication (VLC) system. The gated retro-reflector includes a retro-reflector and a gating shutter between the retro-reflector and a light source. A light sensor receives VLC data at regular intervals in which a light pulse received during one of the intervals represents a first downloaded symbol and absence of a light pulse during another one of the intervals represents a second downloaded symbol. A controller controls the gating shutter to send uplink data from the device responsive to each received VLC light pulse. The controller opens the gating shutter during the reception of a VLC light pulse to upload a first uploaded symbol and closes the gating shutter during the reception of a VLC light pulse to upload a second uploaded symbol.

Abstract: An identification marking is incorporated into a light fixture to provide a uniquely identifiable light fixture. The identification marking is humanly imperceptible. Location information for the uniquely identifiable light fixture is obtained by a mobile device after identifying the light fixture based on the identification marking. Location of the mobile device is estimated based on the obtained location information of the uniquely identifiable light fixture.

Abstract: A lighting system utilizes intelligent system elements, such as lighting devices, user interfaces for lighting control or the like and possibly sensors. The system also has a data communication network. Some number of the intelligent lighting system elements, including at least two of the lighting devices, also support wireless communication with non-lighting-system devices at the premises. Each such element has a communication interface system configured to provide a short range, low power wireless data communication link for use by non-lighting-system devices at the premises in proximity to the respective intelligent system element. Also, in such an element, the processor is configured to control communications via the communication interface system so as to provide access to the data network and through the data network to the wide area network outside the premises for non-lighting related communications of the non-lighting-system devices.

Abstract: A lighting device obtains data related to objects and boundaries in an area in the vicinity of the lighting device, and a user wearable device provides a display (e.g. an augmented reality display based on the data related to the objects and the area boundaries) for a user/wearer. The lighting device includes a mapping sensor that collects data related to the objects and boundaries in the area. The user wearable device includes a camera or other optical sensor and wireless communication capability. The user wearable device is provided with mapping data that is presented on a display of the user wearable device. The communications and display capabilities allow the user wearable device to obtain room mapping information related to area in the vicinity of the lighting device in order to provide navigational assistance to a visually impaired person in the area.

Abstract: A system includes luminaires at a premises, where each luminaire has a light source, processor and radio frequency (RF) transceiver. The processor is configured to control the RF transceiver of the respective luminaire to transmit ranging signals to neighboring luminaires and receive response signals from neighboring luminaires. The processor computes time of flight (ToF) values relative to the neighboring luminaires. The system also includes a location solving server having a processor configured to receive the ToF values from the luminaires, compute relative distances between the luminaires based on the ToF values, and determine relative locations of the luminaires within the premises based on the computed relative distances between luminaires. Knowledge of the relative locations of the luminaires, for example, may be used in personnel or asset tracking, e.g. based on data sent via light from the luminaires or by ranging and response signals exchanged with RF enabled assets.

Abstract: An example of a lighting system includes intelligent lighting devices, each of which includes a light source, a communication interface and a processor coupled to control the light source. In such a system, at least one of the lighting devices includes a user input sensor to detect user activity related to user inputs without requiring physical contact of the user; and at least one of the lighting devices includes an output component to provide information output to the user. One or more of the processors in the intelligent lighting devices are further configured to process user inputs detected by the user input sensor, control lighting and control output to a user via the output component so as to implement an interactive user interface for the system, for example, to facilitate user control of lighting operations of the system and/or to act as a user interface portal for other services.
