  • Patent number: 9854995
    Abstract: A method, system, and process are described to decrease muscle fatigue and improve circulation of an individual resting on a support device, such as an adjustable chair or bed. The body pose and heat distribution of the individual are determined and used to estimate muscle fatigue and circulation. The estimated muscle fatigue and circulation are then used to determine settings for the support device or the temperature of the environment.
    Type: Grant

  • Patent number: 8135511
    Abstract: An electronic control system, electronic control unit and an associated methodology for adapting a vehicle system are provided. A visual sensor detects a three dimensional profile of an occupant of a vehicle. An electronic control unit determines at least one of three dimensional locations and orientations of a plurality of body parts of the occupant of the vehicle, a body-volume of the occupant of the vehicle and body dynamics of the occupant of the vehicle based on the three dimensional profile detected by the visual sensor. The electronic control unit adapts a vehicle system based on at least one of the determined three dimensional locations and orientations, the determined body-volume and the determined body dynamics.

  • Patent number: 8098165
    Abstract: A system, apparatus and associated methodology for interactively monitoring and reducing driver drowsiness use a plurality of drowsiness detection exercises to precisely detect driver drowsiness levels, and a plurality of drowsiness reduction exercises to reduce the detected drowsiness level. A plurality of sensors detect driver motion and position in order to measure driver performance of the drowsiness detection exercises and/or the drowsiness reduction exercises. The driver performance is used to compute a drowsiness level, which is then compared to a threshold. The system provides the driver with drowsiness reduction exercises at predetermined intervals when the drowsiness level is above the threshold.
