Latest Patents
David B. Morgan holds a patent for a "Digital pulse-width modulated printer escapement control system." This invention discloses a digital escapement control system in which the motor (DC) control is entirely digital, eliminating the need for tachometer generation of feedback signals or any analog to digital converters. The system utilizes a code wheel and detector connected to the DC motor shaft to determine the time between discrete positions of the motor shaft as it rotates. The time is compared with a desired time, and the difference is stored in a register. This difference is then converted to a pulse-width-modulated (PWM) signal, which directly controls the rotational velocity of the motor, adjusting it as necessary. The system operates in a ramp, open-loop startup mode and a digital velocity-controlled braking mode during motion, with feedback incorporated at a predetermined velocity level.
