Abstract: An LED-based light has an elongate housing having a longitudinal axis and a vertical axis, the housing defined by a base and two canted outer walls meeting opposite the base, the housing defining a cavity. An LED circuit board on which a plurality of LEDs are located is positioned within the cavity. End caps are positioned at opposite ends of the housing.

Abstract: Techniques are described for a lighting system in which light sources are controllable using signals sent over a wireless mesh network. During a commissioning process, a user interface (UI) may present a representation of nodes (e.g., light sources, sensors, controllers, etc.) that are broadcasting a wireless advertising signal. In response to a selection of a particular node, a wireless message may be sent to instruct the selected node to provide a visual indication of its presence, such as a flashing light. The visual indication may enable a user to discern the physical location of the node, such that each node may be added to the mesh network and, in some instances, to a group of nodes. The UI may also enable the definition of scenes, where each scene describes the brightness level or other operating characteristics of particular light source(s) and/or group(s) of light sources when the scene is active.

Abstract: An LED-based light includes one or more LEDs, a sensor arranged to detect a brightness level in an area resulting from the combination of light emitted by the LEDs with light from at least one ambient light source other than the LEDs, and operable to output a signal corresponding to the detected brightness level, a controller operable to regulate an amount of power provided to the LEDs in response to the signal, a light transmitting housing for the LEDs, the sensor and the controller and a connector shaped for connection with a light socket disposed at an end of the housing.

Abstract: An LED-based light can be installed in a conventional light fixture. The LED-based light can include a sensor operable to output a signal indicative of whether an area of one or more of the rooms is in an occupied state or a non-occupied state, and the LED-based light can also include an LED controller operable to control at least one LED in the light in response to the signal. Additionally, the LED-based light can include a transmitter operable to output the signal indicative of whether the area is in the occupied state or the non-occupied state to a building environment regulator.

Abstract: For controlling operation of a light source, a method of associating a light source with an area for which the light source is positioned to provide lighting comprises: identifying, based on a determined physical position of a light source, one of a plurality of areas as the area for which the light source is positioned to provide lighting; identifying at least one desired lighting condition for the identified area; and controlling, using a processor, operation of the light source based on the identified at least one desired lighting condition for the identified area.

Abstract: An example system for detecting a beer keg includes a transmitter assembly attached to the beer keg, a receiver assembly attached to a handle for attaching to the mouth of the beer keg, and a data processing apparatus in communication with the receiver assembly. The transmitter assembly includes a memory storing a unique identifier for the beer keg, a wireless transmitter for transmitting a wireless signal encoding the unique identifier, and a loop antenna positioned around a mouth of the beer keg. The receiver assembly includes a reader for reading the wireless signal from the transmitter beacon when the handle is attached to the mouth. The data processing is programmed to detect the unique identifier based on the wireless signal read by the reader.
