Part 3/9:
What sets this 4D radar apart is its unique application—it does not function as an outward-facing sensor aimed at other vehicles on the road. Instead, it's designed to work within the cabin, providing real-time data on passenger presence and health. This innovative design aims to enhance safety through dynamic airbag deployment and emergency response measures. The 4D radar can monitor heart rates and breathing patterns, which could be lifesaving if a child were inadvertently left in a vehicle on a hot day.
