Abstract: A backhaul system operative to: increase network capacity, prevent unwanted re-transmissions, and facilitate multiple hopes. The system utilizes a first sequence and a second sequence of periods in conjunction with wireless packet transmission by several adjacent nodes, thereby (i) preventing a transmission of a downlink packet to a mid-point communication node from interfering with reception of any previous downlink packet in a node adjacent to the mid-point node, (ii) preventing a transmission of an uplink packet to the mid-point node from interfering with reception of any previous uplink packet in yet another node that is also adjacent to the mid-point node, and (iii) preventing transmissions of packets by the mid-point node from interfering with reception of any other packet in the mid-point node. Multiple beams are then used to counter a residual effect of multiple transmissions arriving in the mid-point node at the same time.

Abstract: System and methods for wirelessly transporting data from a first communication node to a second communication node using different combinations of beams and on a packet-by-packet basis. Packets associated with a certain Quality of Service (QoS) and/or latency requirements are transported between the first and the second nodes using a first transmission path, while packets associated with a different QoS/latency requirements, are transported between the first and the second nodes using another transmission path, in which in order to switch from the first path to the second path, the system adjusts appropriate beam directions in real-time, and so as to result in fast-switching beam configurations that dynamically change in accordance to packet movement in the network. Latency-critical packets are directed to the faster path, while other packets are directed to the slower path, so as to prevent network congestion and optimize overall network performance.

Abstract: Lighting systems combine UV-A and white light with an adjustable CCT value so that any adverse effects from the UV-A radiation are mitigated—that is, tunable adjustments to the output of the non-UV LEDs, or to all of the LEDs, result in an overall mixed output conforming to a target CCT value.

Abstract: An illumination device includes first and second solid, wedge-shaped waveguides and first and second light-emitting diodes (LEDs) positioned to couple light into the waveguides. Mixed light is emitted from (i) at least a portion of the first surface of the first waveguide and/or (ii) at least a portion of the first surface of the second waveguide, the mixed light including light emitted by the first LED and light emitted by the second LED.

Abstract: A lighting device producing white light having a target color correlated temperature (CCT) value includes an LED array having one or more red LEDs, one or more warm white LEDs, and one or more cool white LED; one or more photo-luminescent materials for shifting the CCT value of the light emitted from the cool white LED toward a green CCT value and/or the CCT value of the light emitted from the warm white LED toward a yellow CCT value; and a waveguide material having a mixing region for mixing the shifted and unshifted light so as to generate white light having the target CCT value and an output region for outputting the white light.

Abstract: An illumination device includes a solid waveguide; a plurality of light emitting diodes emitting light of different colors and arranged to project light into at least one of the surfaces of the waveguide; and one or more phosphor materials for converting light emitted by one of the LEDs from one color to another, such that an out-coupling region of the waveguide outputs a mixture of light from at least some of the LEDs and light converted by the phosphors materials.
