  • Geolocation with redundant aircraft antennas system and related method
    Patent number: 9523761
    Abstract: A system and method is disclosed for using two or more currently installed antenna elements on a vehicle for geolocation of a remote emitter. Redundant antenna elements initially installed for a non-geolocation purpose are employed to receive signals from the remote emitter. A splitter is used to tap from the received signal where the content of the received signal, if desired, is available to a non-geolocation receiver for which the antenna element was originally designed. The splitter transmits the split portion of the signal to a geolocation sensing receiver for signal processing based on a two or more antenna element geolocation solution.

  • DISPERSIVE TARGET IDENTIFICATION
    Publication number: 20160274218
    Abstract: A first frequency agile waveform and additional frequency agile signal waveform(s) having in-phase and a quadrature phase components, each shifted by a different delta frequency, are transmitted in the direction of a possible dispersive target. Return signal(s) each comprising an in-phase component and a quadrature phase component associated with each of the frequency agile waveform(s) are received. The return signal(s) associated with the frequency agile signal waveform(s) are phase shifted by their respective delta frequenc(ies). A combined return signal is generated by combining the first return signal and the additional phase shifted return signal(s). A probability of a potential target is determined when the combined return signal exceeds a threshold.

  • Slot-by-slot preamble acquisition control to increase network capacity in mobile ad hoc networks
    Patent number: 9332586
    Abstract: A method and system is disclosed for a local approach within a distributed multi-hop radio environment that switches between a stronger and weaker preamble acquisition. The robustness of the preamble acquisition plays a large part in the performance of a given Signal-in-Space (SiS) modulation scheme. A more robust preamble acquisition can result in a higher packet completion rate at a receiver free of interfering signals. A less robust preamble acquisition can result in less chance that an interfering signal will be acquired, thereby allowing increased spatial reuse and network throughput. To maximize network capacity, the disclosed method leverages both cases by dynamically switching between the less and more robust preamble acquisitions depending on the topology of the distributed multi-hop radio environment and desired quality of service.

  • Interactive baseball simulation between remote team managers
    Patent number: 9162140
    Abstract: A method for simulating a game of baseball via a computer network is playable by opposing managers running game application logic at remote computers communicating with an event outcome server. The server executes steps for receiving selected pitcher data and a pitcher control value from a first remote computer, and receiving, for an engagement with the selected pitcher data, selected batter data from a second remote computer. The server optionally modifies the pitcher control value according to the batter data, and generates a first random number for comparison to the pitcher control value. Based on the comparison, the server selects a set of probabilities representing possible outcomes of the engagement, where one selectable set favors the pitcher and another selectable set favors the batter.
