Radio detector can analyze personal emotional state
Generally speaking, facial expressions are an important way to identify a person's mood and feelings, but in social interaction, many people are unwilling to reveal their true emotions. Have you ever thought that someone can know whether you are happy or sad through a computer or smartphone? According to reports, researchers at the Massachusetts Institute of Technology Computer Science and Artificial Intelligence Laboratory have developed a new version called EQ- Radio's mood detector, this device will release radio frequency waves to the test subject and capture the reflected signal to measure his breathing pattern and heart rate. The obtained data will match different emotional signals with physical factors through an algorithm, and classify people's emotions into four states: sadness, anger, happiness and joy. In the experiment, the researchers asked 12 participants to sit about one meter away from the device, and asked everyone to recall a private experience that made them feel a certain emotion. Each emotion lasted for 2 minutes. Heart rate and breathing rate will be measured to measure the emotions of participants. The results show that the measurement capability of this equipment is quite accurate, with an accuracy rate of 87%. In addition, researchers also improve the accuracy of detection by moving the body. Because the large range of chest movement helps breathing to get rid of the subtle effects of heartbeat. Researchers also found that heart rate, not breathing rate, is the greatest 'indicator' of a person's emotional state. After all, people can hold their breath, but the heartbeat is hard to control. Ru0026D personnel hope that related technologies can be used to develop robotic psychotherapists in the future, or advertising companies can collect feedback from the audience in a timely manner.

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
