    Abstract: A system for determining a location of a user is provided that comprises a plurality of transmitters, each associated with a predefined physical location and each comprising a light source to provide an optical location signal; and at least one head-worn locator device with an optical receiver for receiving at least one of the optical location signals. To allow the determination of a location of a user that is wearing the head-worn locator device, each transmitter is configured to provide location information in the respectively provided optical location signal, wherein said location information corresponds to said predefined physical location of the respective transmitter.

    Abstract: A coded localization system includes a plurality of optical channels arranged to cooperatively distribute electromagnetic energy from at least one object onto a plurality of detectors. Each of the channels includes a localization code that is different from any other localization code in other channels, to modify electromagnetic energy passing therethrough. Digital outputs from the detectors are processable to determine sub-pixel localization of the object onto the detectors, such that a location of the object is determined more accurately than by detector geometry alone. Another coded localization system includes a plurality of optical channels arranged to cooperatively distribute a partially polarized signal onto a plurality of pixels. Each of the channels includes a polarization code that is different from any other polarization code in other channels to uniquely polarize electromagnetic energy passing therethrough. Digital outputs from the detectors are processable to determine a polarization pattern.

    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: Apparatuses, methods, apparatuses and systems for a light fixture are disclosed. One apparatus of the light fixture includes a sensor unit and a light intensity controller. The sensor unit includes a sensor operative to generate a sense signal base on at least one of sensed motion or light, wireless communication circuitry operative to maintain a link with a network, and a controller. The controller is operative to manage communication with the network, manage reception of beacons through the wireless communication circuitry, wherein the beacons are received from an object, and the beacons include information associated with the object, and generate dimming control base on at least one of the sensed signal and communication from the network. The light intensity controller is configured to receive the dimming control and operative to adjust an emitted light intensity of a luminaire of the light fixture.
