Invention Description Accurately detecting stress using wearable devices is challenging due to significant differences in how individuals respond physiologically to stress. Variations in factors such as heart rate, skin conductance, and environmental conditions can reduce the reliability of stress detection models across different users. Many existing...

Background Wireless communications systems in 5G and beyond are using high-frequency signals (in the mmWave band in 5G and sub-terahertz bands in 6G and beyond). The large bandwidth available at these high frequencies enable the communication systems to send data at very high rates. However, increasing frequency comes at the expense of lower penetration...
