    摘要: A multi-region lighting system for flat illumination includes one or more light sources and an optic. The optic comprises a first region characterized by a first refractive-index feature and a second region characterized by a second refractive-index feature. The second region comprises a ridge structure. The first and second refractive-index features and the ridge structure are operative to produce a composite light distribution from the one or more light sources.

    摘要: In an example, a method comprises communicating with a radio frequency (RF)-enabled asset tag within a space, tracking a location of the RF-enabled asset tag within the space, determining location estimates of the asset tag as the asset tag moves within the space, and accepting identifying information from or about a selected user. The method additionally comprises determining, based on a predetermined correspondence criteria, a correspondence between the asset tag location and a position estimate of an electronic hardware device within the space. Further, in response to determining the correspondence between the asset tag and the electronic hardware device and based at least in part on the identifying information accepted via the electronic hardware device, the method includes associating tracked asset tag location information corresponding to the location estimates of the asset tag as the asset tag moved within the space to identification of the selected user.

    摘要: An emergency luminaire includes an emergency luminaire light source to emit emergency illumination lighting. The emergency luminaire also includes an emergency luminaire power supply configured to be driven by an emergency power line. The emergency luminaire further includes emergency luminaire programming, wherein execution of the emergency luminaire programming configures the emergency luminaire to implement the following functions. The emergency luminaire tracks an active message gap time. In response to receiving a normal power active message from a respective member device of a plurality of member devices of a lighting control group before the tracked active message gap time exceeds an active message timeout, the emergency luminaire resets the active message gap time. In response to the tracked active message gap time exceeding the active message timeout, the emergency luminaire enters an emergency mode (EM) active state by controlling the emergency luminaire light source to emit the emergency illumination lighting.

    摘要: A lighting system includes a plurality of lighting system elements. The lighting system elements include a luminaire and a reporting device. The luminaire includes a light source to emit illumination light. The reporting device includes a reporting device network communication interface system for network communication, a reporting device processor, a reporting device memory, and reporting device programming in the reporting device memory. Execution of the reporting device programming causes the respective reporting device to collect a respective performance metric of a respective luminaire and submits a respective claim including the respective performance metric to one or more storage devices. A respective storage device validates a plurality of claims, including the respective claim. The storage device stores the subset or all of the plurality of claims in a block in at least one storage device of the one or more storage devices. The block includes a lighting value token.

    摘要: A lighting system includes a wake-up light source to emit a wake-up light beam and a plurality of luminaires located in a space. A respective luminaire includes an illumination light source to emit illumination lighting for the space, a light sensor to detect light, a wireless transceiver configured for wireless communication, and a memory. The respective luminaire further includes a processor coupled to the light sensor, the wireless transceiver, and the memory. The respective luminaire further includes wake-up programming in the memory. Execution of the wake-up programming by the processor causes the respective luminaire to: (a) detect a plurality of light measurements above a light threshold; (b) determine whether the plurality of light measurements are in accordance with a pattern; and (c) in response to determining the plurality of light measurements are in accordance with the pattern, enter a beaconing mode.

    摘要: An ultraviolet (“UV”) emission device may emit energy towards a movable surface of a conveyor system, A housing of the UV emission device may attach to a frame of the conveyor system. A lateral edge of the housing may extend across the moveable surface. The housing and a portion of the moveable surface may be inclined with respect to the frame. A barrier bracket of the UV emission device may support an absorptive barrier along the lateral edge, the absorptive barrier configured to contact the moveable surface. In a first position of the barrier bracket, the absorptive barrier contacts the moveable surface and the barrier bracket activates an interlock switch. In a second position of the barrier bracket, the barrier bracket deactivates the interlock switch. Responsive to deactivation of the interlock switch, a controller may provide a control signal to decrease power to the UV energy emission element.
