Latest Patents

One of his latest patents is the "MIMO cable guided intrusion detection sensor." This invention relates to a Multiple Input Multiple Output (MIMO) covert terrain-following outdoor perimeter security sensor. It is designed to detect, locate, and categorize intruders as they move in proximity to buried sensor cables. The MIMO cable guided radar utilizes parallel standard leaky coaxial cables with uniform apertures in the outer conductor. RF transmissions from both ends of one cable set up an invisible electromagnetic detection field that couples into parallel receive cables. When an intruder moves within the coupled electromagnetic fields, the amplitude and phase of the multiple received signals are altered. The joint processing of the responses seen from both ends of the cables provides uniform sensitivity along the length of the cables without the need for expensive graded cables. This invention allows for tracking intruders crossing the perimeter, thereby reducing the number of nuisance and false alarms.

Another significant patent is the "Cable guided intrusion detection sensor, system and method." This invention provides an intrusion detecting system and method for precisely locating an intruder along the length of a sensor cable. It determines the intruder's distance from the cable to accurately locate multiple, simultaneously occurring intrusions. The method includes generating a TX signal and transmitting it over a first transmission line of the sensor cable to create an electromagnetic field. The system detects an RX signal induced in a second transmission line of the cable by the electromagnetic field. It identifies contra-directional and co-directional reflections to provide coordinates of the target. This invention also achieves ultra-high-speed data correlation of the RX signal through the use of a field-programmable gate array.
