Patent attributes
A vehicle seating system is described that can detect and optionally quantify a drowsiness state and/or and emotional state of a seat occupant in the vehicle. A seat is mounted in a vehicle and houses a wireless electromagnetic sensing system at least partially integrated into the seat. These sensed signals can be used to determine the occupant's state. When the state exceeds a threshold, then wireless stimulation emitters output a stimulation signal to the occupant to alter the emotion state or drowsiness state to move the occupant to below the threshold and to a calm state or an alert state. The system can also use additional physiological sensor to measure at least one of a heart rate, a respiration rate, or both of the occupant to be used with the electromagnetic sensing at the seat.
