Houston tech company aims to make campuses more secure with tracking device

Can't pass this up

There's an only public service announcement from the 1960s that asks, "It's 10:00 p.m., do you know where your children are?" The idea behind it was to encourage parents to ensure their children's safety, by encouraging them to be home before what was then the youth curfew in several states.

"Do you know where your visitors are right now?" asks the SafePass website, providing an answer: "You do if you have SafePass."

The visitor management system is the brainchild of Ronald Huff, who initially envisioned the system as a hall pass for students. The electronic pass would monitor students in real time, if they left class to go to the nurse or the restroom, meaning adults would be able to find them in the event of an emergency. But as Huff and his business partners proceeded through product development, they realized SafePass had a stronger lure as a system that could manage visitors across several platforms – business, schools, and secure environments.

The system works like this: companies issue a SafePass visitor badge to visitors, contractors or others who are temporarily on the grounds of their facilities. The badge records signal strengths from WiFi routers set up around the facility and tracks where the visitor is in real time.

"Visitors don't know a facility as well as the people who work there every day do," said Huff. "If there's smoke or a fire, they might get lost. So, SafePass helps provide a record of where they are, meaning that people can find them if there's an emergency or an evacuation."

SafePass is also reusable. The electronic badge is designed to be used over and over again, unlike common printed paper badges that visitors stick on.

"We're 100 percent eco-friendly," said Huff.

He and his partners built the demo for the product at the end of 2017 and began shopping it at trade shows. The reaction was immediate, with multiple companies wanting to take on the system. SafePass is about to launch a pilot phase with some Fortune 100 companies, and has plans to expand soon beyond that.

Companies can currently email their floor plans to SafePass, which creates routes within the floor plans, fixing geolocations. Then the signal strength from WiFi routers is digitally mapped within the building using an Android app. This allows the electronic badge to know where a guest is as he or she is traveling throughout a given facility.

"I think most people know that cell phones record almost everything we do," said Huff, explaining that SafePass isn't designed to infringe on personal privacy. "This isn't a Big Brother situation. Above all else, we're concerned about the safety of both people who are visiting a facility and those who work there every day."

Huff said SafePass can also help companies with safety and security compliance. For instance, oil and gas companies are audited by third parties on how secure their facilities are. SafePass' technology helps them not only score higher on an audit, but actually keep their facilities secure.

"A product like ours solves so many different problems," he said.

After nearly two and half years of development, Huff said he's excited about what's to come.

"This is really my baby," he said of the company. "And it's been such a blessing to work with this team of developers and programmers and sales people. We've got a great team and great clients. This is a dream come true."

SafePass has made a splash on the Houston digital innovation scene and was even named one of the most promising startups at the recent Texas Digital Summit.

Rice University lands $18M to revolutionize lymphatic disease detection

fresh funding

An arm of the U.S. Department of Health and Human Services has awarded $18 million to scientists at Rice University for research that has the potential to revolutionize how lymphatic diseases are detected and help increase survivability.

The lymphatic system is the network of vessels all over the body that help eliminate waste, absorb fat and maintain fluid balance. Diseases in this system are often difficult to detect early due to the small size of the vessels and the invasiveness of biopsy testing. Though survival rates of lymph disease have skyrocketed in the United States over the last five years, it still claims around 200,000 people in the country annually.

Early detection of complex lymphatic anomalies (CLAs) and lymphedema is essential in increasing successful treatment rates. That’s where Rice University’s SynthX Center, directed by Han Xiao and Lei Li, an assistant professor of electrical and computer engineering, comes in.

Aided by researchers from Texas Children’s Hospital, Baylor College of Medicine, the University of Texas at Dallas and the University of Texas Southwestern Medical Center, the center is pioneering two technologies: the Visual Imaging System for Tracing and Analyzing Lymphatics with Photoacoustics (VISTA-LYMPH) and Digital Plasmonic Nanobubble Detection for Protein (DIAMOND-P).

Simply put, VISTA-LYMPH uses photoacoustic tomography (PAT), a combination of light and sound, to more accurately map the tiny vessels of the lymphatic system. The process is more effective than diagnostic tools that use only light or sound, independent of one another. The research award is through the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program, part of the U.S. HHS, which saw the potential of VISTA-LYMPH in animal tests that produced finely detailed diagnostic maps.

“Thanks to ARPA-H’s award, we will build the most advanced PAT system to image the body’s lymphatic network with unprecedented resolution and speed, enabling earlier and more accurate diagnosis,” Li said in a news release.

Meanwhile, DIAMOND-P could replace the older, less exact immunoassay. It uses laser-heated vapors of plasmonic nanoparticles to detect viruses without having to separate or amplify, and at room temperature, greatly simplifying the process. This is an important part of greater diagnosis because even with VISTA-LYMPH’s greater imaging accuracy, many lymphatic diseases still do not appear. Detecting biological markers is still necessary.

According to Rice, the efforts will help address lymphatic disorders, including Gorham-Stout disease, kaposiform lymphangiomatosis and generalized lymphatic anomaly. They also could help manage conditions associated with lymphatic dysfunction, including cancer metastasis, cardiovascular disease and neurodegeneration.

“By validating VISTA-LYMPH and DIAMOND-P in both preclinical and clinical settings, the team aims to establish a comprehensive diagnostic pipeline for lymphatic diseases and potentially beyond,” Xiao added in the release.

The ARPA-H award funds the project for up to five years.

Houston doctor wins NIH grant to test virtual reality for ICU delirium

Virtual healing

Think of it like a reverse version of The Matrix. A person wakes up in a hospital bed and gets plugged into a virtual reality game world in order to heal.

While it may sound far-fetched, Dr. Hina Faisal, a Houston Methodist critical care specialist in the Department of Surgery, was recently awarded a $242,000 grant from the National Institute of Health to test the effects of VR games on patients coming out of major surgery in the intensive care unit (ICU).

The five-year study will focus on older patients using mental stimulation techniques to reduce incidences of delirium. The award comes courtesy of the National Institute on Aging K76 Paul B. Beeson Emerging Leaders Career Development Award in Aging.

“As the population of older adults continues to grow, the need for effective, scalable interventions to prevent postoperative complications like delirium is more important than ever,” Faisal said in a news release.

ICU delirium is a serious condition that can lead to major complications and even death. Roughly 87 percent of patients who undergo major surgery involving intubation will experience some form of delirium coming out of anesthesia. Causes can range from infection to drug reactions. While many cases are mild, prolonged ICU delirium may prevent a patient from following medical advice or even cause them to hurt themselves.

Using VR games to treat delirium is a rapidly emerging and exciting branch of medicine. Studies show that VR games can help promote mental activity, memory and cognitive function. However, the full benefits are currently unknown as studies have been hampered by small patient populations.

Faisal believes that half of all ICU delirium cases are preventable through VR treatment. Currently, a general lack of knowledge and resources has been holding back the advancement of the treatment.

Hopefully, the work of Faisal in one of the busiest medical cities in the world can alleviate that problem as she spends the next half-decade plugging patients into games to aid in their healing.
