  • Sensor fall curve identification
    Patent number: 11327476
    Abstract: A computer implemented method includes turning off a sensor, receiving fall curve data from the sensor, and comparing the received fall curve data to a set of fall curve signatures to identify the sensor or a sensor fault.
    Type: Grant
    Filed: November 13, 2018
    Date of Patent: May 10, 2022

  • Systems and methods for monitoring driver state
    Patent number: 10867195
    Abstract: Systems and techniques for monitoring driver state are described herein. In an example, a driver state monitoring system is adapted to receive a set of color images of a person, such as images of a driver of a vehicle with varying levels of illumination in the images. The driver state monitoring system may be further adapted to generate a set of synthesized thermal images from the set of color images. The driver state monitoring system may be further adapted to use a trained thermal image face detector to locate a human face in the synthesized thermal images. The driver state monitoring system may be further adapted to use a trained thermal image facial landmark predictor to locate facial landmarks in the synthesized thermal images. The driver state monitoring system may be further adapted to analyze the facial landmarks in the synthesized thermal images to determine facial feature movements.
