Abstract
A sensing system determines movement and position of passengers and objects within a vehicle. The sensing system comprises a group a group of transmitting antennas operably connected to a car seat, each transmitting antenna adapted to transmit a signal that is orthogonal to each other signal transmitted during an integration period; a plurality of receiving antennas, each one of the plurality of receiving antennas adapted to receive transmitted signals; and a processor adapted to determine a measurement of the transmitted signals received and create a heatmap, wherein a heatmap summation is taken during no-touch events, compared to a baseline heatmap, and a new baseline heatmap recalibrated if a threshold is exceeded.
