InCabin vital signs monitoring & Child Presence Detection on SemiDrive platform
At CES 2025, MulticoreWare and Cadence showcased their latest in-cabin radar sensing solution, running on the SemiDrive platform powered by the Cadence Vision VP6 DSP.
Real-time vital sign monitoring of multiple occupants is achieved with a 60GHz radar, which can differentiate between living and non-living entities.
It ensures accurate passenger detection, even for children in confined spaces. This vital innovation enhances safety by enabling proactive interventions like child presence detection, now recognized and rewarded under Euro NCAP safety protocols.
