Latest Patents

James D. Cummins holds two noteworthy patents that showcase his ingenuity. The first, titled "Radio Transceiver for Data Communications," details a compact, low-power radio frequency transceiver designed to facilitate wireless communication between a computer and other devices. This invention includes a direct conversion receiver, a voltage-controlled oscillator, phase lock loop circuits, digitally controlled divider circuits, and a patch antenna, all packed into a size compatible with the PCMCIA format. Notably, the transceiver can enter a sleep mode when idle to conserve power and features a signature detector that distinguishes between noise and valid messages by recognizing an embedded signature word in data packets.

The second patent, "Stylus Position Digitizer Using Acoustic Waves," presents a novel digitizing method that employs acoustic waves initiated from a stylus to pinpoint its position on a plate. By introducing acoustic waves from the stylus tip and detecting them via multiple sensors located along the periphery of the plate, a microprocessor can accurately calculate the stylus's position using the time differences of wave arrivals. This innovative device can utilize either 'fast' symmetrical waves or 'slow' antisymmetrical waves, defining stylus position for various applications.
