As fall creeps closer, the need for a safe way to reopen schools becomes more and more dire. A team of Rice University students created a software that might help on that front.

SchoolTrace, a software that uses the schedules of students and faculty for COVID-19 contact tracing in schools, won top honors in the 2020 Rice Design-A-Thon, which took place July 17 to 19 online this year due to the pandemic. The hackathon was planned to be held in person during the fall semester, but organizers moved up the date to focus on coronavirus solutions. Twenty-three teams — comprised of 116 undergraduate competitors — participated.

"We wanted to provide students with a meaningful summer opportunity and the potential for a significant public health impact," says Carrigan Hudgins, a Sid Richardson College senior and co-coordinator, in a news release. "At one point, we considered cancelling, but hosting it virtually instead actually allowed us to reach a broader base of students across Texas and out of state."

SchoolTrace and its contact tracing tech that doesn't raise privacy concerns with tracking sensors or mobile phone apps took the $1,000 first price. Justin Cheung, Nick Glaze, Mit Mehta, Tyler Montague and Huzaifah Shamim — all juniors majoring in electrical and computer engineering — also received $500 for excelling in the digital age of health care track.

The teams that came in second and third place received $800 and $600, respectively, and the winners of each of the three design tracks also scored $500. The prizes were sponsored by Rice's George R. Brown School of Engineering, Rice's student chapter of the Biomedical Engineering Society and the Southwest National Pediatric Device Innovation Consortium.

Aside from the cash prizes, the students also received valuable guidances and feedback from industry experts.

"Having the judges and our team vouch for the actual solution, when we can propose it to different competitions and incubators around Texas and the country, is more important than the cash prizes," says co-coordinator Franklin Briones, a Brown College senior who competed in previous design-a-thons at Rice. Briones and Hudgins co-coordinated this year's event with Wiess College senior Eric Torres.

Here were the other award-winning innovations to come out of the program:

  • Second place and pediatric track winner — "Team SARS Wars: A New Hope." The team created a soap dispenser attachment that plays music and rewards children with stickers if they wash their hands for 20 seconds. Team members included: Anyssa Castorina, Aman Eujayl, Diego Lopez-Bernal, Janet Lu, Rubén Sebastián Marroquín, and Belén Szentes, all sophomores from Rice.
  • Third place — "The (d^3x/dt^3)(s)." COV-COM is a wall-mounted filtration system that catches and kills COVID-19 created by a team of juniors and seniors from the University of Texas at San Antonio. Team members included: Olivia Garza, Juan Herrera, Frida Montoya, Aishwarya Sathish, Samantha Strahan, and Morgan Struthers.
  • Global health track winner — "The Duncaroo Designers." The team from Rice created affordable desk partitions that could be used in schools with limited funds. Team members included: senior Rachel Bui and sophomores Jacob Duplantis, Charlie Gorton, Andrei Mitrofan, Anh Nguyen, and Vivian Wong.

Each of the teams were tasked Friday (July 17) evening with the prompt to "design and present a solution (either a product or a method) to address the treatment, prevention or non-medical related needs of the COVID-19 pandemic." Final presentations took place final presentations Sunday afternoon.

"The needs-finding for those problems was the most cumbersome part," Briones says in the release. "Not because it's hard to find problems, but because COVID-19 is so continually changing. It was hard to find which problem was the most important one."

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
