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 visually tracking movement associated with a mobile device in order to determine optimal locations for handing over the device between different base stations arranged in a sequence. Initially, a current location of the mobile device is determined via a radio access network associated with the device. Then, a moving object is visually detected in an immediate proximity to the location determined, using a visual sensor array associated with the radio access network. The moving object detected is assumed to be associated with the mobile device due to said proximity, and is hence visually tracked along its path of progression, until arriving at a location that was previously determined to be optimal for performing a handover between two adjacent base stations. A handover is then executed, while continuing with said visual tracking until another handover is required.

Abstract: System and methods for detecting, analyzing, and understanding various events involving dynamic objects interacting with static/quasi-static objects. A plurality of edge devices first conduct a visual survey of a certain indoor and/or outdoor area over a certain period of time to detect quasi-static object that do not substantially move during that certain period of time. The quasi-static objects are then classified for functional purpose and geometrically dimensioned/geo-spatially positioned. The edge devices then conduct a real-time visual survey to detect, classify, and dimension/position different types of dynamic objects, such as pedestrians and vehicles. The information obtained on the dynamic objects is then combined using geo-spatial parameters/common coordinate system with the information obtained on the quasi-static object to identify/classify events such as pedestrians using a crosswalk to cross a street, vehicles parking in designated parking areas, and shoppers entering stores.

Abstract: Approaches for updating a firmware file in a network having multiple transceiver nodes and being capable of receiving and transmitting the firmware file include dividing the firmware file into multiple of chunks, each chunk being able to be included in a single data packet transmitted between two of the transceiver nodes; transmitting each of the chunks from the first one of the transceiver nodes to the second one of the transceiver nodes; transmitting a request message from the first one of the transceiver nodes to the second one of the transceiver nodes, the request message including information associated with the chunks that have been transmitted in step (b); and transmitting a responding message from the second one of the transceiver nodes to the first one of the transceiver nodes, the responding message including information associated with one or more chunks that are included in the request message but not received by the second one of the transceiver nodes.

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.

The apparatus may include at least one processor. The at least one processor may be configured to determine a value indicative of energy absorbable by the object at each of a plurality of frequencies and to cause the at least one radiating element to apply energy to the zone in at least a subset of the plurality of frequencies. Energy applied to the zone at each of the subset of frequencies may be a function of the absorbable energy value at each frequency.

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: To promote efficient and reliable communication of beacons among neighboring nodes in a wireless network, instead of having each node transmit beacons over its operational channel and switch to a different channel to receive its one-hop neighbors' beacons, nodes may transmit beacons over a different channel (i.e., different from the operational channel) and receive beacons over their operational channels. These outgoing “visitor beacons” may contain the usual beacon information but most importantly specify the operating channel of the transmitting node over which conventional beacons may be transmitted and received.
