In-Cabin Integrated Sensing & Communication (ISAC) Care

ISACCare unites vehicular radar sensing and high-speed in-cabin wireless communication into a single unified radio-frequency platform. By repurposing 60 GHz and 77 GHz RF transceivers, it delivers ultra-precise contactless vital signs monitoring while streaming gigabit telemetry across the vehicle cabin.

Eliminating Redundant In-Cabin Silicon via Integrated Sensing and Communications

Modern vehicles clutter the headliner with separate Wi-Fi routers, Bluetooth modules, child presence radars, and gesture sensors, driving up wiring weight and electromagnetic interference. ISACCare uses a single agile phased-array transceiver to transmit high-speed data packets while simultaneously processing their radar reflection echoes to measure human respiration.

Core Engineering Areas

• OFDM Dual-Function Waveforms — Embedding communications bits into subcarrier symbols while applying 2D FFT radar processing across received pilots to extract spatial range-velocity matrices.
• Contactless Micro-Doppler Sensing — Extracting the minute 0.1mm to 0.5mm chest wall vibrations caused by heart ventricle pumping, separating it from the larger 5mm to 12mm breathing cycle motion.
• Multi-Occupant Spatial Beamforming — Steering narrow radio beam pencils dynamically toward each passenger seat to isolate physiological signals from adjacent seat neighbors.
