Latest Patents

Gammell's latest patents include innovative technologies that enhance the detection of corrosion. One of his notable inventions is a method for subsurface examination of non-ferrous material for detecting corrosion. This invention utilizes a magnetic field generator positioned externally to a non-ferrous metallic structure. The generator is rotated at a low speed to create a rotating magnetic field that penetrates the metallic structure to a selected depth. The traction between the metallic structure and the magnetic field is measured, allowing for the detection and quantification of corrosion at subsurface depths.

Another significant patent is the non-contacting capacitance probe for dielectric cure monitoring. This device employs conductive measuring electrodes within a capacitive probe to provide mutual capacitance measurements. The probe is positioned in a non-embedded manner relative to the dielectric material, forming a sensitivity region through which an electric field extends. This innovative approach allows for variable mutual capacitance measurements without extraneous influences during the curing process.
