Latest Patents

One of his latest innovations is an eddy current inspection tool designed for testing and inspecting metal objects in hard-to-reach locations. This miniaturized inspection tool incorporates eddy current sensing equipment, a probe coil, and a coaxial coil cable. It features circuit means that respond to impedance changes in the coil, producing a data output signal proportional to these changes. The tool is designed to be used with a flexible fiberoptic scope, allowing for precise control of coil placement relative to the test object. Additionally, the eddy current sensing equipment includes a tone generator that provides audible signals based on the data output, enhancing the detection of discontinuities.

Another significant invention is a video flowmeter capable of specifying the flow nature and pattern while quantifying the rate of volumetric flow. This device forms an image of a specific volumetric region within a fluid containing entrained particles. The flowmeter is calibrated to determine the volumetric flow rate based on the positions of the particle images displayed on a video screen.
