Introduction

Frank Martin Stephan is a notable inventor based in Galveston, Indiana. He holds a total of eight patents, showcasing his contributions to innovative technologies. His work primarily focuses on user-manipulated apparatuses and circuitry for measuring mechanical stress.

Latest Patents

One of his latest patents is a user-manipulated line marking apparatus. This device allows users to produce straight construction lines on sheet material with ease. The apparatus features a linearly extensive frame with an integrally formed handle and an expendable marking strip affixed to its bottom edge. Users can position the frame to align with the endpoints of a desired construction line, ensuring the marking strip contacts the surface of the sheet material. By linearly displacing the frame, the marking strip rubs along the surface, creating a visible construction line. The design includes a compliant portion of the frame that ensures the marking substance fully engages the surface, accommodating any irregularities.

Another significant patent involves circuitry for measuring mechanical stress on a printed circuit board. This circuit includes electrically conductive pads on the board's surface and a resistive material applied in a specific pattern. The resistive material's electrical resistance varies as it deforms under mechanical stress, allowing for precise monitoring of changes in resistance values. This innovation can enhance the reliability of printed circuit boards in various applications.
