A University of Houston professor of electrical and computer engineering is improving thermal imaging and infrared thermography with a new method to measure the continuous spectrum of light.

Jiming Bao's innovative method involves techniques that will be used to measure and visualize temperature distributions without direct contact with the subject being photographed, according to a news release from the university. The challenges generally faced by conventional thermal imaging is addressed, as the new study hopes to eliminate temperature dependence, and wavelength.

Thermal cameras and infrared thermometers measure temperature accurately from a distance because they are highly sensitive to light, which makes them valuable tools. Fields from the military, building, and mechanical inspections, and medical diagnostics, these industries depend on thermal cameras and infrared since they detect infrared radiation that is invisible to the human eye, and convert it into visible images. The issue is the level of accuracy, which Bao hopes to address with his solution.

“We designed a technique using a near-infrared spectrometer to measure the continuous spectrum and fit it using the ideal blackbody radiation formula,” Bao tells the journal Device. “This technique includes a simple calibration step to eliminate temperature- and wavelength-dependent emissivity.”

By using the near-infrared spectrometer, thermal radiation from a hot target can be collected with an optical fiber and recorded digitally. The collected spectrum is then normalized by using a system calibration response and finally fitted to determine the temperature.

“This technique overcomes challenges faced by conventional thermal cameras and infrared thermometers due to the unknown emissivity of targets and reveals much higher surface temperatures of photothermal catalysts than those measured by a buried thermocouple under strong light illumination,” Bao says in a news release.

Houston Technology Center founder dies, leaves legacy of innovation

saying goodbye

The Houston innovation ecosystem is mourning the loss of one of its early leaders, Paul Frison, who died on September 5. He was 87.

A long-time Houston businessman, Frison founded the Houston Technology Center in 1999 and served as its CEO and president. The organization evolved into Houston Exponential several years ago. Frison remained active within Houston innovation until 2020.

“Paul Frison was a visionary and energetic leader who always presented a positive outlook on what the Houston technology entrepreneurship community could become," Brad Burke, associate vice president for industry and new ventures at Rice University's Office of Innovation, remembers. "He was one of the pioneers in the community who established the Houston Technology Center as one of the early leaders of the Houston ecosystem. I admired how he helped launch the ecosystem and created the platform for many others to build upon.”

Prior to HTC, he served in various executive roles at American Hospital Supply, LifeMark, ComputerCraft, and LifeCell, spending the last 50 of his years in Houston. Born in Glendale, California, he served in the Unites States Coast Guard.

Blair Garrou, co-founder and managing director of Mercury Fund, says Frison was his first boss and mentor in the tech and entrepreneurship sector.

“When people look back to how the Houston tech community was founded, it starts with Paul Frison," Garrou says. "Paul had run multiple companies and I was lucky to have him as CEO when I worked for him at the Houston Technology Center. He quickly became a mentor, and over time, a good friend and confidant. I have Paul to thank for launching my career in tech and venture capital.

"My favorite quote of Paul’s was, 'Do not confuse effort with results,'” Garrou continues. "Despite his results-driven work ethic – which was legendary — Paul was also deeply-rooted in family and faith, and has been a role model for me over my entire professional life.”

He is preceded in death by his wife, Barbara, and his grandson, Christian David Elders. He is survived by his daughters Maryanne Elders and Jill Cortez and their families, including grandchildren Matthew Elders, Laney Elders, Max Cortez, Jake Cortez, and Sofie Cortez.

A celebration of life will be held for Frison on September 16 at 1 pm at Second Baptist Church, with a reception following in the Deacon’s Parlor. More details are available online. In lieu of flowers, Frison's wishes were for for donations to Second Baptist Church to be made in his honor.

Artist collective brings carbon-absorbing murals to Houston

WHEN FINE ART MEETS FRESH AIR

Anthony Rose, the CEO of creative agency United By Design, is on a mission to brighten Houston’s urban spaces and improve the city’s air quality one carbon-absorbing mural at a time.

Rose originally founded United By Design, or UXD, in 2019 to connect muralists like himself and commercial businesses seeking to beautify their spaces and form brand identities. After creating vibrant murals for Lockhart Elementary School, the Houston Astros, and Smoothie King, Rose expanded UXD’s vision to include environmental sustainability in their artistic collaborations in 2022.

“This city’s vibrant art scene and growing focus on sustainability makes it an ideal location for our projects,” Rose says. “We’re not just creating eco-friendly murals, we’re reimagining how art can actively contribute to environmental solutions.”

In search of ecologically-conscious paints, Rose formed a partnership with Spain-based, natural paint company Graphenstone. Rose says he was drawn to the company’s eponymous Graphenstone coating because of its nontoxic ingredients and exclusively uses the product for UXD’s carbon-absorbing murals.

The Graphenstone coating consists of a limestone base which goes through a process called photocatalysis, during which carbon dioxide from the atmosphere is absorbed into the surface, and is then sealed in with graphene, a thin layer of carbon atoms. The murals absorb carbon dioxide throughout the coat’s drying process which typically takes 30 days.

“Each of our murals absorbs about 1600 grams of CO2 during that curing process which is the equivalent daily absorption of about 33 growing trees,” Rose explains.

UXD’s largest carbon-absorbing mural to date is a floor-to-ceiling panorama in downtown Houston’s historic Mellie Esperson building, home to the company’s new creative hub. Painted by Houston-born artist Emily Ding, the mural is a tribute to the establishment’s namesake: an innovative, early 20th century entrepreneur who constructed the opulent building.

Rose says UXD plans to expand their carbon-absorbing murals project in collaboration with more local artists and establishments, while creating an artist-in-residency program themed around sustainability. Though Rose acknowledges in the grand scheme of carbon pollution these murals are not a silver bullet, he says the non-toxic paints are encouraging conversations about how artists can be conservation-minded.

“We’re trying to figure out how art as a messaging tool can help break down scientific data, a language not many people practice daily, can break down barriers and help bridge the gap to a more intuitive knowledge of sustainability,” Rose says. “We’re bringing the community together, helping them feel empowered, and giving them actionable information to help them live more sustainable lives.”

Houston innovators to know this week

who's who

Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes a health tech innovator, an investor, and a startup CEO.

Jon Nordby, managing director of Anthropy Partners

In his role overseeing startup accelerators for MassChallenge, Jon Nordby started noticing one industry vertical stood out in terms of success and opportunities: Human potential. Now, Nordby is a founding member of an investment firm looking for those opportunities.

Nordby, who served in various leadership roles at MassChallenge — including managing director and head of ecosystems — said he started realizing the opportunities within the organization's space and sports tech programs.

"What we realized over a couple of years running the program was that sports tech as a theme was too limiting," Nordby says on the Houston Innovators Podcast. "We were finding really great technologies, but we were limited at the market size of teams and leagues to deploy those technologies."

"Over the course of that program, we found that the things that were related more to human health and performance tended to out perform all of the other things related to sports tech — like media, entertainment, gambling," Nordby continues. "Still really great markets for those technologies, but we found a lot more traction for human performance." Read more.

After many years of living to eat, a large swath of American society is now facilitating a seismic shift to the healthier alternative, eating to live.

But here’s the rub: eating healthy is confusing, time consuming and, unfortunately, oftentimes pricey.

So, anyone that can come in and cut through the healthy eating machine can carve out a necessary niche in the marketplace.

Enter Houstonian Mark Semmelbeck, founder and CEO of A Better Meal, a platform created to help busy families plan healthy meals easier and to make gradual improvements to their health and well-being.

“My vision is to use rapidly expanding AI technology together with the knowledge and wisdom of an active community to take the stress out of meal planning and improving nutrition,” says Semmelbeck, a seasoned oil and gas executive with over 30 years of experience in founding companies. “While developing the technology for the app, my daughter gave me two beautiful grandkids who both have significant food allergies. Combine that with the fact I now have five cardiac stents and the significance of eating well while paying attention to the details has only grown in importance.” Read more.
