Patent attributes
Vehicle including a seat in which an occupant sits during use of the vehicle and a monitoring system for monitoring the occupant in the seat. The monitoring system includes sets of electric field antennas, each including at least one antenna, a control unit connected to the antenna sets and including selectors coupled to the antennas. The selectors are controlled by the control unit to obtain signals from one or more antennas serving as receiving antennas and one or more antennas serving as sending antennas. The control unit determines which combination of sending antenna(s) and receiving antenna(s) provides a strongest signal in an expected heartbeat range and/or expected respiration range of the occupant and then monitors this combination for changes and/or deviations from a normal range of heartbeats and/or respiration.
