  • Publication number: 20190141822
    Abstract: A lighting fixture having a light source, a light sensor, a communication interface, and circuitry is described. In addition to controlling the light source, the circuitry is adapted to monitor for a light signal provided from a handheld device via the light sensor; upon receiving the light signal, measure a signal level associated with the light signal; and effect transmission of the signal level to the handheld device via the communication interface. In one embodiment, the circuitry is further configured to receive an instruction to monitor for the light signal from the handheld device via the communication interface such that the circuitry begins monitoring for the light signal upon receiving the instruction.

  • Patent number: 9826598
    Abstract: A lighting fixture includes a solid-state light source, communications circuitry, and control circuitry coupled to the communications circuitry and the solid-state light source. The control circuitry is configured to receive a message from a neighboring device via the communications circuitry, the message indicating the detection of an occupancy event by the neighboring device. Further, the control circuitry is configured to adjust a light output provided by the solid-state light source based on a neighbor ranking of the neighboring device, wherein the neighbor ranking indicates a number of intermediate devices located between the lighting fixture and the neighboring device.

  • Publication number: 20060222081
    Abstract: In KVM systems for comparing new video frames to reference frames to update video, a method of reducing the effects of noise comprising (i) determining the differences between the sets of pixel values for new and reference pixels to produce a difference set of difference elements for each pixel; (ii) weighting the absolute value of each difference element within the difference set (iii) summing the weighted difference elements over all of the pixels of the horizontal line of the sub-block to produce a weighted difference element sum; (iv) determining whether the weighted difference element sum exceeds a predetermined sum threshold; (v) if yes, determining that the sub-block has changed so as to require updating.
