Abstract: A vehicle seat may include a seat body having a seat base and a backrest arranged to extend upward from the base. The seat body may include an exterior covering. The vehicle seat may further include a comfort system disposed within the seat body and including a heating track configured to emit heat.

Abstract: An occupant support includes a vehicle seat and a sensor system coupled to the vehicle seat. The sensor system is configured to provide biometric data of an occupant of the vehicle seat.

Abstract: A system includes multiple capacitive sensors, a multiplexer, a programmable gain amplifier, an oscillator, a switch, and a controller. The sensors are coupled to the multiplexer, the multiplexer is coupled to the switch, and the switch is coupled to the amplifier and the oscillator. The controller may control the multiplexer to select each of the sensors. The controller may control the switch to activate the amplifier or the oscillator. The controller may measure voltage output by the amplifier or frequency output by the oscillator. The system may be included in an occupant support such as a vehicle seat.
