Alumnus takes a voyage through solar system

Chuck Lahmeyer, EE’66, is a big reason why the world knows what distant planets in our solar system look like. In 1975, he went to work for NASA’s Jet Propulsion Lab in California, and in 1980 he developed a machine to host the codes coming from the Voyager spacecraft on its journey to Uranus and Neptune.

The equipment used error-correcting codes created by engineers Irving Reed and Gustave Solomon. Lahmeyer’s Reed-Solomon machinery — on which he holds the patent — removes errors from the transmitted data, similar to cleaning up a snowy television picture. With his device, information on the planets’ brightness, magnetic field and temperature were correctly captured.

Lahmeyer also worked on Galileo, providing the designs for an incoder, a piece of circuit that other technicians later used to capture images and information.

Lahmeyer retired to Missouri and gives back to S&T regularly through his service to the Mid-Missouri Section of the Miner Alumni Association. He is the group’s president.

Honoring new academy members

In October, 12 alumni and friends were inducted into Missouri S&T academies. Academy membership recognizes careers of distinction and invites members to share their wisdom, influence and resources with faculty and students. Some academies hold induction ceremonies in the fall, others in the spring.

Boosting cyber-physical security

A wide array of complex systems that rely on computers — from public water supply systems and electric grids to chemical plants and self-driving vehicles — increasingly come under not just digital but physical attacks. Bruce McMillin, professor and interim chair of computer science at Missouri S&T, is looking to change that by developing stronger safeguards […]

MXene discovery could improve energy storage

In spite of their diminutive size, 2-D titanium carbide materials known as MXenes are “quite reactive” to water, a discovery S&T researchers say could have implications for energy storage and harvesting applications such as batteries, supercapacitors and beyond. Their findings were published in 2018 in the American Chemical Society journal Inorganic Chemistry.

A faster charge for electric vehicles

One drawback of electric vehicles (EVs) is the time it takes to charge them. But what if you could plug in your EV and fully charge it as quickly as it takes to fill up a conventional car with gasoline? Missouri S&T researchers, in collaboration with three private companies, are working to make speedy charging […]
