Latest Patents
One of his latest innovations is the "Neutral Side Force Belt Support System." This system is designed to support a moving photoreceptor belt in an electrophotographic printing machine while minimizing lateral forces applied to it. The design features pairs of idler rolls that are in contact with the inner surface of the belt, arranged so that the axes of rotation of the idlers are skewed at equal but opposite angles from a direction perpendicular to the belt's motion. This configuration allows the resultant lateral forces to act nearly parallel to the axes of rotation, effectively canceling out the side forces and promoting good belt tracking. Additionally, as the idlers rotate freely, drag and tensioning forces on the belt are minimized.
Another significant patent is the "Stepper Motor Control to Vary Output Torque." This mechanical drive system accommodates different load requirements by adjusting the motor's input in response to changes in output torque needs during various segments of the duty cycle. For instance, in a copier, a DC stepper motor drives a fuser roll at a specific speed while a copy sheet is in the fusing area. Once the fusing process is complete, the load requirements increase, necessitating higher torque from the motor. The system intelligently reduces the motor speed while allowing it to produce the additional torque required.
