Title: Innovations of Douglas Edward Smith

Introduction

Douglas Edward Smith is an accomplished inventor based in Westford, MA (US). He holds two patents that showcase his expertise in data correction and validation technologies. His work has significantly contributed to the reliability and efficiency of communication systems.

Latest Patents

One of his latest patents is titled "Method and apparatus for correcting data." This invention provides a system and method for using a first data channel to pass working data and a second data channel to pass error correction information. The second data channel may be defined along a redundant data path, allowing for the forwarding of forward error correction (FEC) information, such as Hamming code information. This approach offers several advantages, including the ability to correct bit errors within the system, enhancing its reliability. Additionally, the use of a protected path allows for constant monitoring of the quality of both the working and redundant paths. This monitoring utilizes FEC information to accurately count errors, enabling proactive problem diagnosis before a switch to the redundant path is necessary.

Another significant patent is the "Method of and apparatus for validating data read out of a multi-port." This invention enhances the performance of a multi-port internal cached DRAM (AMPIC DRAM) by providing an internal method of data validation. It ensures that only valid requested data is returned or properly marked as invalid. This modified technique identifies bad data read from AMPIC memory devices, improving the overall reliability of data retrieval.
