  • UNIFIED COMMUNICATION GATEWAY SYSTEMS
    Publication number: 20200374267
    Abstract: A communication system utilizing unified gateways bridges communication gaps between data transmitters having differing transmission, security, data format, overhead restrictions and performance metrics by dynamically determining optimal data paths for the data being routed. The unified gateways can also dynamically alter data packages to upgrade/downgrade security standards, alter transmission networks, translate data to match recipient requirements and split/combine data to optimize data throughput using disparate systems.

  • Extended range communications for ultra-wideband network nodes
    Patent number: 10541720
    Abstract: A system is provided that can introduce data redundancy into wireless communications, and in particular ultra-wideband (UWB) wireless communications to increase the communication range when transmitting data that has low transmission rates. Multipath degradation, introduced by the extended communications range, can be mitigated by frequency hopping between the orthogonal frequency-division multiplexed symbols of the ultra-wideband waveform. Frequency hopping can place adjacent symbols in different frequency channels for filtering. Data redundancy can be expanded in the time domain and/or the frequency domain, resulting in extended range.

  • STEERABLE BEAM ANTENNA WITH CONTROLLABLY VARIABLE POLARIZATION
    Publication number: 20190379120
    Abstract: A steerable beam antenna includes a feed line and first and second arrays of switchable scatterers along opposite sides of the feed line. The first array scatters an electromagnetic wave propagating through the feed line to form a first beam portion with a first polarization, and the second array scatters the propagating wave to form a second beam portion with a second polarization orthogonal to the first polarization. Each scatterer in the first and second arrays is switchable between a high state and a low state, the high state scatterers and the low-state scatterers in each of the first and second arrays defining a periodic pattern. The scatterers in the first and second arrays are switchable to shift the pattern of scatterers in one of the arrays relative to the pattern in the other array by a selectable period shift that yields a desired polarization for the beam.
