With a total of three patents to his name, Schmidt's innovations are particularly focused on improving the functionality and safety of lift truck operations.

Latest Patents

Schmidt's latest inventions include groundbreaking patents such as the "Lift truck control providing time delay in operation of directional" and the "Chopper motor controller having pulse-by-pulse sensing of plugging." The first patent describes a sophisticated chopper motor-controller designed to regulate lift truck traction motors, incorporating fault detection mechanisms to enhance operational safety. This invention prevents the truck from running out of control by disabling the controller in response to any detected faults, ensuring a more reliable and efficient operation. It also features a time delay function to prevent premature engagement of directional contactors in the event of a fault.

The second patent advances the technology of pulse width modulation chopper controllers for Direct Current (D.C.) traction motors. This innovative design includes plug sensing capabilities that monitor the armature voltage on a pulse-by-pulse basis. It adeptly limits the 'on-time' of the power switch, thereby mitigating the risk of high current surges when the motor functions as a generator.
