Latest Patents

One of McInnis's latest patents is the Triboelectric sensor and methods for manufacturing. This invention involves triboelectric sensors that generate electrical signals in response to mechanical disturbances. These sensors are fabricated from thin metal foil, which is plastic-coated on one side. They can be formed into elongated, cable-like sensors with various shapes and sizes. The foil encloses one or more wire-like inner electrical conductors, which may be sealed within the envelope formed by the outer foil through heat-sealing. A technique similar to welding can be employed, where electrodes are placed in contact with opposing faces of the metal foil, allowing an electrical current to pass through. This process causes local heating of the foil and the plastic coating, enabling the plastic faces to bond together.

Another significant patent is the Automated tennis line calling system. This system is designed for the automatic detection of ball bounces on a tennis court and is applicable to similar games. It comprises a sonar-like sound system combined with a pressure-sensitive system located on the court surface. The sound system utilizes multiple microphones to detect sounds and analyze them to calculate the position of balls striking the court surface. The pressure system detects ball bounces on the boundary lines, using coaxial cables as sensing elements. The pressure system is activated only when the sound system identifies a ball bouncing near the boundary lines. Processing is conducted by a personal computer equipped with a special interface card.
