    Abstract: A load control system for controlling an electrical load in a space of a building occupied by an occupant may include a controller configured to determine the location of the occupant, and a load control device configured to automatically control the electrical load in response to the location of the occupant. The load control system may include a mobile device adapted to be located on or immediately adjacent the occupant and configured to transmit and receive wireless signals. The load control device may be configured to automatically control the electrical load when the mobile device is located in the space. The load control system may further comprise an occupancy sensor and the load control device may automatically control the electrical load when the occupancy sensor indicates that the space is occupied and the mobile device is located in the space.

    Abstract: A lighting device (e.g., a controllable light-emitting diode illumination device) may have a light-generation module that may be assembled and calibrated prior to the light-generation module being installed in a finished good. The light-generation module may include an emitter module having at least one emitter mounted to a substrate and configured to emit light. The light-generation module may include a first printed circuit board on which the emitter module may be mounted and a second printed circuit board on which those circuits that are essential for powering the emitter module may be mounted. The light-generation module may include a heat sink located between the first printed circuit board and the second printed circuit board. The emitter module may be thermally-coupled to the heat sink through the substrate and the first printed circuit board.

    Abstract: A wireless device may receive packets according to a protocol, such as Bluetooth, and may rapidly react to receive an interfering RF packet instead of dropping the first RF packet and the interfering RF packet, to decrease message delay due to collisions in high device density environments. When a received signal strength indicator (RSSI) difference between the interfering RF packet and the first RF packet exceeds a threshold, the device may detect the interfering packet and resync a portion of its circuitry to lock on to and receive the interfering packet. The wireless receiver may detect the interfering RF packet by detecting one or more of: a specific resync byte sequence, an increase in RSSI, or a phase shift. Additionally, a wireless device may add the specific resync byte sequence to an RF packet of a standard protocol.

    Abstract: Wireless devices may perform modified carrier sense multiple access (CSMA) techniques in order to increase reliability while maintaining a reasonable latency for communications. The wireless devices may perform listen-before-talk (LBT) techniques using an adaptive transmission threshold (e.g., an adaptive CSMA threshold). The transmission threshold may be compared to a measured signal strength magnitude to determine whether the frequency channel is quiet enough for transmission of a packet. The transmission threshold may be initially set to equal a minimum value. The wireless device may increase the transmission threshold after each instance of LBT failure to allow the wireless device to get progressively more likely to transmit the packet each time LBT fails.

    Abstract: A load control system for controlling a plurality of lighting loads located in a space may be configured to track the location of one or more tracked devices. The load control system may comprise a system controller, lighting control devices, e.g., for controlling a plurality of lighting loads, and tracked devices. The tracked devices may each transmit beacon messages. The lighting control devices may receive the beacon message. The lighting control devices may measure a communication quality metric of each of the beacon messages, and process the measured communication quality metrics received over a period of time to determine a processed communication quality metric for the tracked device. The lighting control devices may transmit tracking data to the system controller. The system controller may determine a location of the tracked device. For example, the system controller may determine the location of the tracked device via trilateration.

    Abstract: A control device may be configured to transmit messages using an adaptive transmit power. The control device may determine a transmit power for transmitting the message based on a command in the message. The control device may determine a transmit power based on a change in lighting intensity caused by the command. The transmit power may be greater when the change in lighting intensity is above a threshold than when the change in light intensity is below the threshold. The control device may determine whether the message was successfully received based on the receipt of an acknowledgement message. The control device may increase the transmit power when the message fails to be received and retransmit the message including the command at an increased transmit power. The control device may store (e.g., learn) the increased transmit power for later use.
