Latest Patents

One of his latest patents is titled "Servo control of bi-directional reel-to-reel tape drives using fine-line." This invention addresses air entrainment effects in a bi-directional tape transport system, allowing magnetic tape to be moved in either direction for data recording. The control of tape position is implemented through a servo algorithm that utilizes tachometer inputs to generate reel motor drive currents. A fine-line tachometer is mounted on each reel, and multiplexing selects the output from the tachometer on the reel supplying tape for the servo algorithm. Additionally, at least one tachometer generates an index line once per revolution, indicating the motor's predetermined threading position.

Another significant patent by Garcia is the "Self adjusting tachometer." This invention describes an electro-optical tachometer assembly designed for devices with movable and fixed parts, such as motors. The assembly includes a movable disk and a fixed mask, with a constant gap maintained by a resilient member. A light-emitting diode (LED) phototransistor assembly outputs electrical signals indicative of shaft speed and direction. Synchronization of the tachometer output to the shaft is achieved through a guide pin arrangement.
