Latest Patents

One of his latest patents is for a low-cost quiet impact printer. This invention features a serial impact printer that includes a platen mounted for rotation upon a support frame. It also has a print element with character imprinting portions and a print element selector for positioning the selected character imprinting portion at a printing position. The design incorporates a high effective mass hammer that drives each selected character imprinting portion to deform the platen with a printing force. Additionally, a carriage supports the print element and other components, while a stationary reaction bar develops the printing force as the hammer deforms the platen.

Another significant patent is the ribbon deck motor control. This apparatus adapts a common DC motor for use in a typewriter to drive the ribbon lift and advance functions. The motor is connected to a shaft with ribbon advance gear and lift cams. An optical sensor outputs a signal for each slot on a slotted disk mounted on the shaft. A processor computes the motor speed from the slot timing and regulates its speed through modulated pulses.
