Sam Kingston has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Sensing system and method with integral sensor locating capability
    Patent number: 8570150
    Abstract: A sensing system includes integrated sensor locating capability. Sensors can transmit spread spectrum encoded data pulses which are received at mobile nodes. Based on time of arrival information and known locations of the mobile nodes, locations of the sensors can be determined.

  • System and method for protecting against denial of service attacks
    Patent number: 7861298
    Abstract: A system and method is disclosed for protecting a receiver configured to receive a plurality of contemporaneous spread spectrum signal bursts from a denial of service attack. The method includes the operation of detecting a burst transmission that includes a random burst number. The burst transmission can be analyzed to determine a denial of service statistic based on the random burst number. The burst transmission is processed when the denial of service statistic is within a predetermined threshold.

  • System and method for detecting a presence and frequency offset of a spread spectrum radio frequency signal
    Patent number: 7672415
    Abstract: A system and method for detecting a presence and frequency offset of a spread spectrum radio frequency signal is disclosed. The method comprises receiving the spread spectrum radio signal. The signal can be sampled to form a plurality of signal samples. Each signal sample can be multiplied by a complex conjugate of a proximate signal sample to form a plurality of signal sample pairs. The signal sample pairs can be summed over a predetermined dwell time period to form a data vector having a magnitude and angle offset to enable detection of the signal and to enable a frequency offset between the spread spectrum radio frequency signal and a receiver frequency reference to be determined.

  • System and method for determining a fine frequency offset of a received signal
    Patent number: 7602834
    Abstract: A system and method for determining a fine frequency offset of a composite code spread spectrum signal is disclosed. The method includes despreading at least one component of the composite spread spectrum signal to form a partially despread composite spread spectrum signal. A set of on-time samples are selected from the signal. The set of on-time samples are rotated by a predetermined frequency amount. The set of rotated samples are placed into a plurality of frequency bins, with each frequency bin representative of a different frequency estimate. An energy for the signal in each frequency bin is determined to find the bin having the greatest energy.
