Abstract: System and method for concurrent STAP (space-time adaptive processing) filtering of interference signals (e.g., jamming signals) from signals received at a broadband antenna array via satellite and terrestrial broadcasts and communication systems operating in the 950 MHz to 1.65 GHz L-band, including but not limited to Link 16 terrestrial communications, Iridium satellite communications, and the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS). While the GPS/GNSS signals are protected against jamming using Nulling of the interfering signals, the Iridium and other communication systems' signals are protected using Beamforming. Use of a common broadband antenna and common front-end signal processing of the received signals enables an integrated system for use on a wide range of platforms, including without limitation size-, weight-, and power-constrained platforms such as drones, unmanned aerial vehicles (UAVs), and helicopters.

Abstract: System and method for concurrently protecting Iridium and GPS L1/L2 band received satellite signals against interference signals (e.g., jamming signals) using space-time adaptive processing (STAP). While the GPS signal is protected against jamming using Nulling of the interfering signals, the Iridium signal is protected using Beamforming. A single broadband small controlled reception pattern antenna (sCRPA) array receives both the GPS (L1 and L2) and Iridium signals for the STAP-based antijam solutions outputting filtered Iridium and GPS signals. Use of a common (small) broadband antenna and common front end signal processing of the received signals enables an integrated system for use on size, weight, and power constrained platforms such as drones, unmanned aerial vehicles (UAVs), and helicopters.

Abstract: System and method for mean phase compensation of code and carrier phase distortions induced by Space Time Adaptive Processing (STAP) filters used for removing interferences from received GPS signals. The phase distortion is mitigated (without the use of beamforming) using a single STAP filter for processing the GPS satellite channels in which appropriate bundling of constraints is applied to the filter weights. The complete solution can be contained in the antenna electronics with no required changes to the legacy GPS receiver.

Abstract: In a first embodiment, a portable, battery-operated, minimally invasive small fiber neuropathy testing and diagnostic device, microcontrolled and interfacing with wireless powering to a wireless communications device is being disclosed. Said device is constructed out of an intra-epidermal thermal stimulus consisting of an electronically heated temperature-controlled polymer covered semiconductor material 101 lowered inside the skin through a probe 108 configured with three miniaturized electrodes 109 while a nerve impulse response measurement system records and identifies nerve action potential pulses through a proprietary algorithm. The invention also discloses a detection and characterization method of action potential pulses from neuron cells with respect to their timing such as pulse repetition statistics and rates from a single-point of measurement as diagnostically relevant for determining neuropathies.
