Patent attributes
An occupant support includes a vehicle seat, a sensor coupled to the vehicle seat, and a controller coupled to the sensor. The sensor provides a signal to the controller and the controller processes and responds to the sensed signal. In illustrative embodiments, a controller includes a sensor module, a filter module, and a biometrics module. The sensor module retrieves sensor data indicative of an occupant of a vehicle seat from one or more sensors of a vehicle. The filter module determines a filter function in a frequency range in which useful biological data may be derived. The filter function identifies one or more frequencies of noise in the sensor data and applies the filter function to the sensor data to generate filtered sensor data. The biometrics module determines biometric data associated with the occupant based on the filtered sensor data.
