Latest Patents
One of his notable inventions is the solenoid valve assembly. This assembly features a slidable valve member that responds to a selectively energizable solenoid coil and a spring. It effectively controls the opening and closing of pressure and exhaust ports through the movement of the valve member. When the pressure port is fully opened, the valve member is seated against a solenoid stop and port member. This design includes a central flow passage that serves as the exhaust passage for the valve assembly. The surrounding valve seat area has a frusto-conical surface with a groove that reduces flow forces on the valve member, thereby lowering the necessary unseating force to open the exhaust port.
Another significant patent is the releasable binding system for snowboarding. This system includes releasable toe and heel binding clips secured to the forward and rear ends of the ski board. The simulated toe and heel members engage with these clips along an axis parallel to the ski board's longitudinal axis. In one embodiment, the release of one ski boot binding triggers the simultaneous release of the other. This innovative design allows for lateral movement of the user's leg, providing a high degree of control while snowboarding.
