Abstract: Techniques and architecture are disclosed for mobile transport systems configured to determine vehicle positions within an area using light-based communication signals. The system includes a plurality of luminaires located in an area and configured to transmit luminaire position data recognizable by a sensor disposed on a vehicle. The sensor receives an image of a luminaire including a light-based communication signal encoded with luminaire position data. Luminaire position data can be combined with luminaire layout information to determine a known location of the luminaire. A vehicle position relative to the known luminaire location can be determined based on mathematical relationships. Vehicle orientation relative to the area can be determined based an asymmetric fiducial pattern or multiple known luminaire locations. The system can combine a vehicle position relative to a known luminaire location with vehicle orientation relative to the area to determine a vehicle position relative to the area.

Abstract: A presence or an absence of an occupant is detected, and an occupancy sensor signal is generated representative of an active state in which the presence of the occupant is detected, and an inactive state in which the absence of the occupant is detected. An ambient light sensor detects the ambient light level and generates an ambient light sensor signal representative of the ambient light level. Dimmable illumination is generated at a first dimming level, based on the ambient light level, corresponding to the active state and a second dimming level corresponding to the inactive state. A transition delay time between an onset of the inactive state and a transition between the first dimming level and the second dimming level may be controlled. The first dimming level, the second dimming level, and/or the transition delay time may be variably set or controlled locally or via a remote device.

Abstract: Aspects of the present disclosure include arrays of motion sensors that may be used to monitor a space to determine occupancy characteristics of the space, such as whether or not the space is occupied and the number of people located within the space. The array of motion sensors may be operatively connected to one or more building system components, such as lighting and HVAC equipment and can be used for adjusting an operating condition of the building system component based on whether a space is occupied.

Abstract: The systems and methods disclosed herein include a LED driver, including a current output module configured to generate a constant current output split between a plurality of output channels, each output channel connected to one or more LEDs having an associated CCT value, at least one switch encoding a plurality of lumen settings and a plurality of CCT settings, and at least one circuit coupled to the current output module and the switch, the at least one circuit configured to determine a first lumen setting from the plurality of lumen settings encoded by the at least one switch, adjust the constant current output of the current output module based on the first lumen setting, determine a first CCT setting from the plurality of CCT settings encoded by the at least one switch, and adjust the plurality of output channels of the current output module based on the first CCT setting.

Abstract: First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.

Abstract: Color tunable lighting systems and methods are disclosed. The color tunable lighting systems and methods include user interfaces that allow for the control of color temperature and luminous intensity by a user. The systems and methods provide for flexibility and scalability, where a control module for controlling one or more solid state light source arrays can be programmed during installation for use with specific solid state light source arrays.

Abstract: Optimized routing in localized dense networks is provided. A packet is received at a first network device in a network. An optimal route for the packet to a neighbor network device in the network is determined using a Source Routing Table (SRT), wherein the SRT includes an optimized routing table and a standard routing table, and wherein the optimized routing table comprises a list of neighbor network devices that the first network device can route to directly and wherein the standard routing table comprises a ZigBee source routing table. The packet is routed using the optimal route.

Abstract: A vehicle lamp capsule 32 having a base 34 having a spring 5 which, when lamp capsule 32 is installed, biases an inner surface of a vehicle lamp reflector 12. Spring 5 is monolithically formed with base 34 along with at least one reflector-locating structure on the base such as circumferentially extending exterior locating surface 44 and/or retaining keys 42. Base 34 and spring 5 may be molded of a plastics material. In other embodiments base 34 and spring 5 are made in one piece of sheet metal. The spring 5 formed unitary with the lamp base 34 meets regulatory requirements and avoids a risk of dislodgement of a conventional separate piece-part metal spring which could cause an electrical short when the lamp is installed in the field. The lamp capsule 32 is suitably an H13-style lamp.
