Houston-based Velentium played a key role in mobilizing thousands of ventilators in the United States at a time when the pandemic and the uncertainty around it was surmounting around the country.

The medical technology company primarily worked in code, software, and cloud-based programs up until March.

"Then we had this opportunity come up in COVID that changed everything for us," says CEO Dan Purvis.

On March 14, an article for Forbes referenced one of Velentium's long-time clients Ventec Life Systems, a manufacturer of ventilators based in Washington. In the article, their client said they could increase production of their much-needed ventilators five-fold if they only had the right resources and partners. Purvis quickly decided that he and his team at Velentium would be one of them.

Velentium first aimed to help the small factory double or triple their production.

"When we first joined the process we were just going to our client, which was a relatively young start up firm, to try to help them go from 120 to 250 [units]," Purvis says.

But then General Motors showed up. And the scale changed dramatically.

The automotive behemoth launched Project V, which would marry it's manufacturing prowess with the technical expertise of the technology and engineering companies to mass produce Ventec's VOCSN ventilator systems. By March 25, operations launched at GM's Kokomo, Indiana, powerhouse plant where they were to produce 10,000 ventilators per month in just about eight week's time.

Velentium was charged with creating 141 automated test stands to verify that every one of Project V's 10,000 units were up to FDA standards. The stands featured 27 unique test systems that monitored 14 critical subcomponents, like air flow in metering valves and oxygen blends, and ultimately approved a ventilator for use through two final tests.

"It's one thing to build [ventilators]," Purvis says. "You need to build them safely, accurately, and in a repeatable way that is going to help people. And that's what our test systems insured."

And though Velentium had created many of these systems before, they had never done so at this scale or speed. Success required around-the-clock work from the then-60-person firm and new risks, that today Purvis says were worth taking.

"I was like, 'If we really want this to work we have to jump on this like nobody's business,'" Purvis recalls. "We bought $2 million worth of parts for test systems essentially at risk. We had not gotten our negotiation with General Motors done yet. But there was no way I could wait an extra week if I had eight weeks to do it. It was kind of terrifying, but it was the right thing to do. It totally aligned with our culture of saving lives."

By September 1, Project V delivered its first order of 30,000 ventilators to the U.S. Department of Health and Human Services, just 154 days after launching.

Today, Velentium maintains a few team members at the Kokomo facility who run sustaining engineering. Throughout the project, Velentium added 60 team members to their staff and doubled down on manufacturing capabilities. They plan to double their production space again as they continue to place more emphasis on their manufacturing arm, which Purvis says opens up new opportunities for the firm that he hopes only continues to grow.

"One of the big goals for me as a strategic leader at the company was to make sure that pre-Project V to post-Project V the transformation that happened to our company through that period would not regress to where we were before," he says. "We had so much impact and so much growth through that time I didn't ever want to change."

He adds: "We asked the question over and over again during the first few weeks of the pandemic in March: Why not us? If I will continue to ask the question…we can accomplish major things."

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

12 winners named at CERAWeek clean tech pitch competition in Houston

top teams

Twelve teams from around the country, including several from Houston, took home top honors at this year's Energy Venture Day and Pitch Competition at CERAWeek.

The fast-paced event, held March 25, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements in the energy transition to present 3.5-minute pitches before investors and industry partners during CERAWeek's Agora program.

The competition is a qualifying event for the Startup World Cup, where teams compete for a $1 million investment prize.

PolyJoule won in the Track C competition and was named the overall winner of the pitch event. The Boston-based company will go on to compete in the Startup World Cup held this fall in San Francisco.

PolyJoule was spun out of MIT and is developing conductive polymer battery technology for energy storage.

Rice University's Resonant Thermal Systems won the second-place prize and $15,000 in the student track, known as TEX-E. The team's STREED solution converts high-salinity water into fresh water while recovering valuable minerals.

Teams from the University of Texas won first and second place in the TEX-E competition, bringing home $25,000 and $10,000, respectively. The student winners were:

Companies that pitched in the three industry tracts competed for non-monetary awards. Here are the companies named "most-promising" by the judges:

Track A | Industrial Efficiency & Decarbonization

Track B | Advanced Manufacturing, Materials, & Other Advanced Technologies

  • First: Licube, based in Houston
  • Second: ZettaJoule, based in Houston and Maryland
  • Third: Oleo

Track C | Innovations for Traditional Energy, Electricity, & the Grid

The teams at this year's Energy Venture Day have collectively raised $707 million in funding, according to Rice. They represent six countries and 12 states. See the full list of companies and investor groups that participated here.
