Title: David T Vaughan: Innovator in Data Transmission Technologies

Introduction

David T Vaughan is a notable inventor based in Tyngsboro, MA (US). He has made significant contributions to the field of data transmission, holding a total of 2 patents. His work focuses on improving the accuracy and efficiency of data communication between subsystems.

Latest Patents

Vaughan's latest patents include a "Method and apparatus for stabilized data transmission." This invention allows for accurate data transmission between two subsystems in a synchronous system, even when clock skew or propagation delay exceeds one clock cycle time. The system initializes both source and destination subsystems to ensure synchronous operation. The source subsystem transmits data along with a forwarded clock, which is then processed through a delay device to introduce a one-half cycle delay. This innovative approach captures data in three state devices arranged in parallel, effectively eliminating minimum delay requirements and expanding data valid time. The captured data is aligned with the destination subsystem's clock by controlling a multiplexer, ensuring that the received data is synchronized.

Another significant patent is the "VSLI latch system and sliver pulse generator with high correlation factor." This VSLI circuit comprises multiple state device circuits on a VLSI chip, each featuring a latch clocked by a pulse generator that produces narrow pulses. These pulses have a width equivalent to the propagation delay through the latch, allowing for the implementation of master-slave flip flops using a single latch and pulse generator.
