Title: Thomas E Cowan: Innovator in Surface Detection Technologies
Introduction
Thomas E Cowan is a notable inventor based in Livermore, CA (US). He has made significant contributions to the field of surface detection technologies, holding a total of 3 patents. His work focuses on innovative techniques that enhance the detection of surface anomalies, which are crucial in various industrial applications.
Latest Patents
Cowan's latest patents include groundbreaking methods for detecting submicron scale cracks and other surface anomalies using positron emission tomography (PET). This advanced surface technique possesses the sensitivity to identify single voids or pits of sub-millimeter size, as well as cracks or fissures of millimeter size. The method can detect features with micrometer-scale depth and nanometer-scale width, making it highly effective for assessing surface integrity. The technique involves exposing a surface to a short-lived radioactive gas, followed by the removal of excess gas to leave a partial monolayer. This allows for the precise determination of the location and shape of cracks, voids, and porous regions. Notably, detection of cracks as shallow as 0.01 mm has been achieved using a 3 mm detector resolution.
Another significant patent involves fan-fold shielded electrical leads made from copper-cladded Kapton. This innovative design features copper cladding on one side serving as a ground plane, while the other side is etched to form the leads. The fan-folded arrangement provides several advantages, including electrical shielding from the environment, non-magnetic properties, and low thermal conductivity, all while being easy to fabricate.
