Latest Patents

One of Rosenthal's latest patents is for a plural robotic drive. This robotic system features two joints that move a common load-bearing member along a designated path for precise load positioning. Each joint is equipped with a linear electric motor and a feedback loop, which drives the motor accurately in response to a commanded position signal and a true position signal provided by sensor apparatus alongside each linear motor's track. The system incorporates cross-coupling circuitry that connects with the sensor apparatus of each joint, producing signals that represent differences in positional error and speed. These signals are injected into the feedback loops to synchronize the travel of the joints. Additionally, window comparator circuitry introduces variable gains to the feedback loops for positional error and velocity values exceeding reference values. The system also employs simultaneous injection of phase lead angle to the electric motors for a transition to high-speed mode while maintaining synchronized operation.

Another significant patent by Rosenthal is related to carrier traverse control for a serial printer. In this invention, a movable type character element, such as a ball or disc, is rotated to present different type characters at the print position. The carrier for the type element moves along the print line at a predetermined maximum velocity, ensuring that the type element can be positioned in time for the next character. If the setup time for the type character exceeds this time, the carrier operates at a slower speed before returning to the predetermined velocity for printing.
