  • Patent number: 10366035
    Abstract: A solution to the technical problem of improving device-to-device connection speeds includes the use of single-wire communication (SWC). Unlike the two differential wires required in transmission lines, SWC includes a transmission method using a single wire for data without requiring a return wire. The use of SWC has the potential to enable low loss channels of increasingly high bandwidth. The SWC improvements in bandwidth and frequency enable a significant reduction of power required for communication. SWC provides significant improvement in speed for each channel, so fewer wires may be used for each device-to-device connection. SWC also provides the ability to convey increased bandwidth and increased power over each wire, which further reduces the number of wires needed to provide power and communication.

  • Patent number: 9209902
    Abstract: A quasi-optical coupling system launches and extracts surface wave communication transmissions from a wire. At millimeter-wave frequencies, where the wavelength is small compared to the macroscopic size of the equipment, the millimeter-wave transmissions can be transported from one place to another and diverted via lenses and reflectors, much like visible light. Transmitters and receivers can be positioned near telephone and power lines and reflectors placed on or near the cables can reflect transmissions onto or off of the cables. The lenses on the transmitters are focused, and the reflectors positioned such that the reflected transmissions are guided waves on the surface of the cables. The reflectors can be polarization sensitive, where one or more of a set of guided wave modes can be reflected off the wire based on the polarization of the guided wave modes and polarization and orientation of the reflector.
