[Asia Economy Reporter Kim Heeyoon] On the morning commute, the long lines in front of building entrances for temperature checks have become one of the new scenes shaped by the novel coronavirus disease (COVID-19). Although passing in front of the camera is all that is required, congestion during rush hour is unavoidable because people must pass one by one. Kim Bangryong, CEO of Envinode, solved the limitation of temperature measurement devices that allow only one person at a time by using artificial intelligence (AI) detection technology.

The AI facial recognition thermal detection system, Dlight Pro, capable of measuring up to 30 people simultaneously, automatically stores the temperature and facial information of entrants, enabling tracking and management of individuals with elevated temperatures. CEO Kim explained, "We developed the system to achieve temperature measurement accuracy within ±0.3℃, comparable to medical-grade devices," adding, "Based on this accuracy, simultaneous measurement of multiple people is possible, making it applicable to various institutions experiencing congestion during entry."

Kim Bang-ryong, CEO of Envinode, who developed AI facial recognition and thermal detection technology capable of measuring up to 30 people simultaneously, was an expert in wireless signal collection and analysis systems. Based on his excellent technical skills, he introduced AI thermal detection systems and air purifiers, expressing his ambition to contribute to the prevention of COVID-19 spread.

AI Deep Learning Technology Applied to Minimize Identification Errors and Environmental Interference

Earlier this year, with the spread of COVID-19, many thermal imaging cameras and devices were introduced, but CEO Kim had doubts about screening errors. He said, "At a building I visited for an external meeting, someone was carrying hot coffee, and the device reacted to the coffee's temperature, displaying it as a human body temperature. This made me question the accuracy of fever temperature identification," adding, "To minimize environmental interference, we integrated AI facial recognition into the thermal detection system to enhance verification functions." He introduced, "Real-time monitoring simultaneously stores the captured face, temperature, date, and time automatically, facilitating government tracking management in case of emergencies."

Envinode is a specialized venture company in signal intelligence that collects and analyzes wireless signals, gaining recognition by supplying electromagnetic wave signal collection systems to the military. Last year, it developed an intelligent air threat situational awareness system that detects and analyzes 29 types of toxic industrial gases, including chemical, biological, radiological, nuclear (CBRN) agents, fine dust, and air quality gases in real time. Based on expertise in signal intelligence and situational awareness, Envinode developed 'Dlight Pro' and also introduced a non-contact temperature measurement system. The Enter Access system, which displays the measured temperature immediately when the back of the hand is brought close to the installed device, is currently being piloted on bus routes in Gyeonggi Province. CEO Kim stated, "It allows quick and easy fever checks on-site when boarding buses, resulting in high satisfaction for both passengers and drivers."

The detection system, which accurately recognizes the human face, sounds a warning light when a fever is detected. The entrant's body temperature and facial information are automatically stored and managed, making it easier to cooperate with health authorities in case of confirmed or suspected patients, according to the company.

Development of a 4-Stage Filtering Air Sterilizer, Eliminating 99.9% of Viruses and Bacteria

Following the development of the thermal detection system, CEO Kim also began developing an air sterilizer dedicated to enclosed public facilities such as elevators and restrooms. The air sterilizer combines a HEPA filter, photocatalyst filter, UVC lamp, and anion generator, capable of sterilizing and removing viruses and bacteria as small as 0.1 μm. Certification reviews are currently underway. While each function has been released as a single product before, CEO Kim explained that this product is unique in integrating all four functions into one.

Formerly with the global telecommunications equipment company Ericsson, CEO Kim rapidly advanced to the position of General Manager in his early 30s, enjoying a successful career. Although a stable future was assured, his passion for work grew, and he increasingly wanted to develop proprietary technology to contribute to the nation and society. After resigning, he founded a frequency-sharing communication company in 1999, achieving success by securing public institution contracts, but had to cease operations due to a patent lawsuit with a global telecommunications company M.

Taking on a second entrepreneurial challenge through Envinode, CEO Kim said, "I believe I found an opportunity to contribute to society with the technology I developed through COVID-19," expressing hope that "the AI thermal detection system and air sterilizer will help prevent the spread of COVID-19."
