Seoul Viosys conducted an air sterilization experiment based on the study of the Korea Central Disease Control Headquarters and the Korea Institute of Science and Technology (KIST), which found out that opening windows frequently can lower the infection rate. When compared to opening windows and ventilating every 10 minutes, the amount of ventilated air with the Violeds air purifier is 6 times bigger, which means that the virus concentration is lowered by 1/6. Along with that, the simulation results confirmed that the chance of infection could be reduced by 1/30. Based on this result, Seoul Viosys designed an air purifying sterilizer to minimize the floating of droplets by optimizing air flow. And it obtained KC certification for the safety of consumers.

A general air purifier HEPA filter can filter fine dust and droplets with a size of 0.3 micrometers (μm) or more. However, since the size of the COVID-19 virus is smaller than 0.1 μm, and the moisture-evaporated virus can pass through the HEPA filter, the general HEPA filters are inadequate to reduce COVID-19 infection. In contrast, the Violeds air purifying sterilizer designed with a triple filter structure can prevent the inflow of the virus by sterilizing 90% of them within 5 minutes, which were carried in droplets and attached to the filter surface. As Violeds technology is the world's first patented technology developed and mass-produced by Seoul Viosys, the license agreement is essential for the business.

"Just as people have the right to drink clean water, we should be able to breathe clean air in indoor spaces," said Lee Young-joo, CEO of Seoul Viosys. "With our Violeds air purifier sterilizers, I hope the government, construction companies, and large multi-use facilities will take an active role in restoring the daily life of people and bringing them back a little bit of happiness, like eating out and drinking a cup of tea."

Quectel Sues Telit, Alleging False Statements, Cybersquatting and Unfair Competition30.10.2026 17:41:00 EET | Press release

Quectel Wireless Solutions, a global end-to-end IoT solutions provider, today announced that it has filed legal action in the United States District Court for the Southern District of Florida against Telit IoT Solutions Inc. The lawsuit seeks to bring an end to Telit’s campaign of false and misleading claims about Quectel and its products. Quectel alleges that, rather than competing on the strength of its products and technology, Telit engaged in a coordinated campaign to undermine Quectel’s reputation by exploiting geopolitical concerns surrounding Chinese technology companies. According to the complaint, Telit funded, promoted, and amplified false and misleading claims about Quectel’s products while positioning itself to customers as a safer “Western” alternative. The lawsuit further alleges that Telit engaged in cybersquatting involving Quectel’s U.S. domain name to advance its campaign. Quectel maintains that these alleged actions have caused substantial harm to its sales, customer

TestMu AI Launches Kane CLI Exploration, an AI Agent That Maps an Entire Web App From a Single URL and Turns It Into Tests30.10.2026 16:00:00 EET | Press release

TestMu AI, the Full Stack Agentic AI Quality Engineering platform, announced Kane CLI Exploration, an autonomous agent that learns a web application before anyone writes a test. Given a single URL, it walks the entire app on its own, flags problems along the way and gives Kane CLI the context it needs to generate and run tests, even when no requirements, user stories or acceptance criteria exist. Every test plan starts from something written down, and many apps never had it. Legacy products lose their specs when the people who wrote them move on, and apps a coding agent built in a week often have no record of intended behavior beyond the prompt history. With nothing to test against, a testing agent ends up grading the app against itself. Starting from the URL a developer provides, the exploration agent moves through every page, junction and flow it can reach, the way a new QA engineer clicks through a product in their first week. For each page it records the controls, the flows in and
