    Abstract: A communications system receives a plurality of input data streams and applies a different orthogonal function to each of the plurality of input data streams. The system processes each of the plurality of input data streams to spatially locate a first group of the plurality of input data streams onto a first carrier signal and to spatially locate a second group of the plurality of input data streams onto a second carrier signal. The system temporally locates the first carrier signal and the second carrier signal onto a third carrier signal and transmits the third carrier signal over a communications link.

    Abstract: A communications system comprises first signal processing circuitry for receiving a plurality of input data streams and applying a different orthogonal function to each of the plurality of input data streams. Second signal processing circuitry processes each of the plurality of input data streams having the different orthogonal function applied thereto to multiplex a first group of the plurality of input data streams having a first group of orthogonal functions applied thereto onto a carrier signal and to multiplex a second group of the plurality of input data streams having a second group of orthogonal functions applied thereto onto the carrier signal. A MIMO transmitter transmits the carrier signal including the first group of the plurality of input data streams having the first group of orthogonal functions applied thereto and the second group of the plurality of input data streams having the second group of orthogonal functions applied thereto over a plurality of separate communications links. Each of the plurality of separate communications links go from one transmitting antenna of a plurality of transmitting antennas to each of a plurality of receiving antennas at a MIMO receiver.

    Abstract: A transceiver for transmitting and receiving full duplex communications includes transmitter and receiver circuitry. The transmitter circuitry transmits from a first location first signals having a first orthogonal function +ln applied thereto on a first channel on a first frequency band to a second location. The receiver circuitry receives at the first location second signals on a second channel on the first frequency band from the second location having a second orthogonal function −ln applied thereto and the first signals having the first orthogonal function +ln applied thereto on the first channel on the first frequency band from the first location at a same time on the first frequency band. The receiver circuitry only processes received signals including the second orthogonal function −ln. The first signals on the first channel are transmitted on the first frequency band on the first frequency band at a same time the second signals on the second channel are received on the first frequency band on the first frequency band.

    Abstract: A system for sterilizing biological material comprising beam generation circuitry for generating a radiating wave having radiating energy therein at a predetermined frequency therein. A controller controls the radiating wave generation at the predetermined frequency. The predetermined frequency equals a resonance frequency of a particular biological material and is determined responsive to a plurality of parameters from an influenza virus. The predetermined frequency induces a mechanical resonance vibration at the resonance frequency of the particular biological material within the particular biological material for destroying a capsid of the particular biological material. Radiating circuitry projects the radiating wave on a predetermined location to destroy the particular biological material at the predetermined location.

    Abstract: A system monitors an individual for conditions indicating a possibility of occurrence of irregular heart events. A database includes a plurality of combinations of at least a first signature and a second signature. A first portion of the plurality of combinations is associated with a normal heartbeat and a second portion of the plurality of combinations is associated with an irregular heart event. A wearable heart monitor that is worn on a body of the patient includes a heart sensor for generating a heart signal responsive to monitoring a beating of a heart of the individual. The monitor further includes a processor for receiving the heart signal from the heart sensor. The processor is configured to analyze the heart signal using a plurality of different processes. Each of the plurality of different processes generates at least one of the first signature and the second signature. The plurality of different processes provide a unique combination including at least the first signature and the second signature for the generated heart signal. The processor compares the unique combination with the plurality of combinations in the database, locates a combination of the plurality of combinations that substantially matches the unique combination and generates a first indication if the unique combination substantially matches one of the first portion of the plurality of combinations and a second indication if the unique combination substantially matches one of the second portion of the plurality of combinations.

    Abstract: A backhaul system comprises a small cell mesh network including a plurality of small cell mesh network backhaul nodes providing a backhaul network to provide an interconnection between at least one first network node for providing access to a core network and at least one second network node for providing access to an edge network. The small cell mesh network comprises a self-organized network (SON). At least one transmitter at each of the plurality of small cell mesh network backhaul nodes establishes communication links with other small cell mesh network backhaul nodes within the small cell mesh network providing the backhaul network. A controller for controlling communication link configuration by the at least one transmitter between the plurality of small cell mesh network backhaul nodes of the small cell mesh network providing the backhaul network. The controller is further configured to implement the self-organized network (SON) that reconfigure new communications links responsive to a broken communications link within the small cell mesh network providing the backhaul network. The communication link configurations are established by the controller using WiGig standards and a MAC layer configured to transmit on a wireless link of the backhaul network.
