Latest Patents

One of his latest patents is titled "Method and system for implementing a communications transceiver using modified GPS user equipment." This invention involves modifying GPS user equipment to implement a communications transceiver. In the data reception mode, it receives a communications signal with a carrier frequency outside the L-band, which has been phase modulated by a PN code and data. The signal is then downconverted to the L-band input frequency of the GPS transceiver and subjected to automatic gain control. The software of the GPS transceiver is modified to recognize and replicate the PN code, allowing for the demodulation of the data-bearing signal. In the data transmission mode, the data to be transmitted is modulated onto the selected PN code sequence and converted to a non L-band transmission frequency, all while maintaining normal GPS navigation functions.

Another significant patent is the "Antijam null steering conformal cylindrical antenna system." This system includes a cylindrical array of linearly polarized individually weighted antenna elements, along with a plurality of weighting circuits associated with each element. It features means responsive to the power output of the weighting circuit, which decreases sensitivity in the direction of maximum incident power, thereby enhancing the system's performance in challenging environments.
