Title: Rafael Pelc: Innovator in Print Technology
Introduction
Rafael Pelc is a notable inventor based in Rochester, MN (US). He has made significant contributions to the field of print technology, holding a total of 3 patents. His work focuses on improving the efficiency and reliability of print element actuators.
Latest Patents
One of Rafael's latest patents is the "Self-timing and self-compensating print wire actuator driver." This invention discloses an improved drive circuit for a print element actuator, wherein the current applied to the actuator has a fast rise mode that is terminated when a predetermined level is reached. The current then slowly decays through the circuit until it reaches a second, lower predetermined level. This circuit is designed to be self-timing and self-compensating for variations in voltage or actuator impedance. Another significant patent is the "Self-switching bidirectional digital line driver." This logic driver circuit repowers signals in either direction along a line without requiring any external direction-control signal. It features two back-to-back driver halves, each including a gate, an open-collector transmitter, and a latch, which prevents race conditions.
