  • Route optimization using star-mesh hybrid topology in localized dense ad-hoc networks
    Patent number: 11575603
    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.

  • METHODS, SYSTEMS, AND APPARATUS FOR PROVIDING VARIABLE ILLUMINATION
    Publication number: 20140333222
    Abstract: Digital Control Ready (DCR) is a two-way open standard for controlling and managing next-generation fixtures. A DCR-enabled lighting fixture responds to digital control signals from a separate digital light agent (DLA) instead of analog dimming signals, eliminating the need for digital-to-analog signal conditioning, fixture-to-fixture variations in response, and calibration specific to each fixture. In addition, a DCR-enabled lighting fixture may also report its power consumption, measured light output, measured color temperature, temperature, and/or other operating parameters to the DLA via the same bidirectional data link that carries the digital control signals to the fixture. The DLA processes these signals in a feedback loop to implement more precise lighting control. The DCR-enabled lighting fixture also transforms AC power to DC power and supplies (and measures) DC power to the DLA via a DCR interface.

  • METHODS, SYSTEMS, AND APPARATUS FOR INTELLIGENT LIGHTING
    Publication number: 20140292208
    Abstract: An ambient light sensor measures an ambient light level at one point in an illuminated environment, such as a warehouse, office, shop, cold-storage facility, or industrial facility, and provides an indication of the measured ambient light level to a processor. The processor maps the measured ambient light level to an estimated ambient light level at a different point in the illuminated environment from the measured ambient light level (e.g., a “task height” about three feet from a warehouse floor). The processor may determine the difference between the estimated ambient light level and a desired light level at the task height, and may change the artificial illumination provided by a light fixture to make the actual ambient light level at task height match the desired light level at the task height.
