Varec Engineer and Patent Awardee Recognized for Developing Innovative Transmitter

(ATLANTA) August 13, 2018 – Varec, a petroleum industry innovator and wholly-owned subsidiary of FORTUNE 500® information technology, engineering, and science leader Leidos, announced one of its engineers was recently recognized for developing an innovative U.S. patent. The recognition took place during a Leidos ceremony honoring all patent awardees across the corporation over the past two years, along with distinguished awardees across other categories.

Dirk Holcomb, a 24-year Varec veteran, was awarded his most recent patent titled Liquid Level Transmitter Utilizing Low Cost, Capacitive, Absolute Encoders, on December 2, 2016. As a Principle Hardware Engineer, Holcomb has been integral in helping Varec develop several new technologies over the years. This latest patent was a result of the unique way he was able to use capacitive encoders for a new transmitter the company was seeking to launch into the market.

Years ago, most transmitters were using optical encoders, which had several drawbacks. Optical encoders were susceptible to dust and other contaminates that could cause LED failure, as well as extended assembly time and high costs. An alternate approach using magnetic encoders suffers from resolution degradation that can arise from misalignment between magnets and sensors. Holcomb’s goal was to develop an encoder that could overcome these issues and provide a reliable, real-time system and process.

The resulting product, the widely popular 2920 Float and Tape Transmitter, is a liquid level monitoring and transmission system that includes a mechanical assembly in communication with the liquid in a container and a dual electronic encoder assembly in communication with the mechanical assembly. The first encoder addresses fine level measurements, with a second encoder for coarse level measurements, in conjunction with a processor for controlling the operation of the two encoders and a power control system.

“We were thrilled when Leidos decided to recognize this patent award at our annual Technical Publication Awards Ceremony,” said Marty Favero, President of Varec. “Innovation is necessary for growth in every organization and Dirk has been a long-tenured and valued innovator on our hardware development team. He has provided us with a number of key additions to our intellectual property over the years and we couldn’t be more proud of his contributions to Varec’s success.”
