Securing device rejoining for a mesh network of a wireless lighting control system is disclosed. A potential security weakness of a mesh network protocol is that a proprietary link key may be discovered by close, expert examination of a device, potentially facilitating the joining of a rogue device to the network. Requiring subsequent rejoins of any device that had previously joined the network to use a current randomly generated link key, rather than the proprietary link key, prevents rogue devices only having the proprietary link key from joining.

Wireless lighting control systems and methods for controlling the illumination of one or more light fixtures are disclosed, including self-commissioning of hardware. Embodiments include a server connected to a wide area network and having software for configuring, monitoring, and controlling lighting fixtures at a site. The control system also includes a wireless gateway at the site initiating communication with the server via a cellular network. Wireless devices initiate communication with the wireless gateway via a mesh network and each wireless device can be wired to control at least one lighting fixture. Once hardware of the site system (e.g., a gateway and/or any device) is mounted or positioned in the appropriate location and powered on, the hardware will self-commission by automatically initiating communications. The gateway will initiate communication and identify itself to server system. When the devices are powered on, they identify themselves to the gateway and the gateway can inform the server system of the devices.

A system in accordance with the present disclosure comprises a sensor and an information processing apparatus that includes processing circuitry. The sensor is installed on a surface so that a detection direction of the sensor is at a non-zero angle from a line normal to the surface. The processing circuitry is configured to communicate with the sensor, calculate a position of a detection area, in which the sensor detects an object in a predetermined space, according to the non-zero angle and a location of the sensor on the surface, and create correspondence information that associates an area of the predetermined space with the detection area.

Wireless signal light systems for vehicles, including wireless illuminated gear and clothing, are provided. In an example system, a wireless transmitter is communicatively coupled to a motorcycle or other vehicle. Receivers in illuminated articles, such as helmet, backpack, jacket, vest, race suit, gloves, boots, and other gear receive signaling information from the transmitter, such as left and right turn signaling and braking of the motorcycle or vehicle. Colored LEDs or other lighting in the illuminated articles mirror the signaling of the motorcycle or vehicle. Left and right gloves and boots may have respective left and right LED turn signal indicators. A pushbutton on each illuminated article synchs the article with the signaling system of the vehicle. The illuminated articles and can sense an emergency through position or by separation from the vehicle and activate emergency flashers, sound, and emergency contacts through a phone. The system batteries also have hazard protection.

An artificial light system that emulates daylight. The system includes at least one light engine, a light diffuser and a controller that is configured to generate light engine control signals based upon geographic location data. The light engine control signals are used to tune at least one of intensity, color temperature and directionality.

Systems, methods, and devices for a networked lighting system are described herein. One system includes a controller for a networked lighting system, comprising, a memory and a processor configured to execute executable instructions stored in the memory to receive, from an image sensor, positions of a number of luminaires in a networked lighting system of a building. The controller further configured to create a lighting map of the networked lighting system based on the received number of luminaire positions and change an address assigned to at least one of the number of luminaires based on the lighting map.

Bed structures are presented. The bed structure may include a bed frame for supporting at least one of a mattress or a mattress foundation, at least one illumination device mounted on the bed frame, and a control system. The control system includes at least one sensor and being configured to illuminate the at least one illumination device responsive to predetermined environmental conditions determined by the at least one sensor. In another aspect, a bed structure includes at least one illumination device mounted on the bed frame, and a control system configured to illuminate the at least one illumination device responsive to predetermined environmental conditions. The control system includes a motion sensor, a light sensor, a timer, and a remote control system facilitating operation of the at least one illumination device responsive to user input control or a predetermined control sequence.

An LED lighting system comprises an elongated linear lamp having an LED luminary as a source of illumination and configured to operate as a node of an automated networked lighting system. The lamp comprise an elongate multi-sided heat sink having first and second LED emitter panels mounted thereon for distributing light outwardly from the emitter panel. A first end cap assembly at the first end of the lamp body houses a communications jack having an internal port for providing an interface operable to transmit power and data signals. The first end cap assembly defines a first opening allowing a network communications plug to be received through the access opening into the internal port of the jack. The linear lamp is operable to receive control data and power signals according to a standardized power and data network communications architecture such as Ethernet.

An autonomous vehicle is disclosed. The vehicle comprises a chassis, two or more drive wheels extending below the chassis, a drive motor housed within the chassis for driving the drive wheels, and a payload surface on top of the chassis for carrying a payload. An illumination system, for emitting light from at least one portion of the chassis, is mounted substantially around the entire perimeter of the chassis. The illumination system may be implemented using an array of light-emitting diodes (LEDs) that are arranged as segments. For example, there may be headlight segments on the front left and front right corners of the chassis.

A lighting control system and method is disclosed for not only controlling visual content loaded within a group set of illumination devices configured within a wireless network, but also for ensuring minimal control delay to those grouped devices. The lighting control system can include a lighting controller device that controls a plurality of lamps within a mesh network, not only to group those lamps but also to assign content to lamps within that group. The combination of a guaranteed groupcast to each of the group of lamps and an acknowledge back from those lamps that is aggregated over a single path achieves the improved lighting control system disclosed herein.
