His innovative work has significant implications for safety and security in various fields.

Latest Patents

One of his latest patents is a "System for the detection and classification of buried unexploded ordnance." This sensor system is designed to detect buried metal objects, such as unexploded ordnance, and collect data for classification based on parameters extracted from the collected data. The system includes a wheeled cart equipped with an array of transmitter coils that transmit excitation signals to the area of interest. It also features a sensor array of receiver coils and preamplifiers that receive the resultant eddy current decays emitted by the buried objects. A computer and data acquisition electronics are used to acquire and store the received decays as decay data. The incoming electromagnetic interference (EMI) data are digitized, and a data fitting process is performed to extract fit location and shape parameters. This data can be transferred to other analysis systems for comparison with previously recorded signatures to determine the nature of the detected objects.

Another significant patent is the "System and method for detecting low metal content buried mines." This method and apparatus are specifically designed to detect mostly-plastic mines that contain steel firing pins and copper igniter cups. The system transmits a frequency spectrum and detects response signals from the metal components induced by resultant eddy currents. The firing pin generates a response characterized by a first frequency that is in phase with the transmitted frequency, while the igniter cup generates a response characterized by a second frequency that is in quadrature with the transmitted frequency. This dual frequency response allows for the discrimination of buried plastic mines from surrounding metal particles in the earth.
