  • Publication number: 20200167951
    Abstract: Systems and methods for optimizing operator-state detection including tracking position of an operator-facing camera are described. Systems and methods include receiving a first image captured by an operator-facing camera, detecting a first position of the operator-facing camera with respect to the calibration object, ascertaining the first position with respect to at least one fiducial marker within a passenger compartment of a vehicle, capturing, via controller, a second image using the operator-facing camera, determining the second image is captured by the operator-facing camera from a second position with respect to the at least one fiducial marker, and analyzing, based on determining the second image is captured by the operator-facing camera from the second position, the second image to identify facial features of the operator. The receiving, detecting, ascertaining, determining, and analyzing are performed via a controller.

  • Patent number: 10346715
    Abstract: Methods and systems are provided for assessing possible misalignment of cameras installed on vehicles. In accordance with one example, a camera is mounted on a body of the vehicle, and is configured to generate camera images. Each of the camera images includes a plurality of pixels. A processor is configured to at least facilitate analyzing the pixels of the camera images with respect to color, brightness, or both; and determining whether the camera is misaligned in its mounting on the vehicle based on the analyzing of the color, the brightness, or both, of the pixels.

  • Patent number: 9081039
    Abstract: Methods and systems are provided for sensing electrical faults. The system includes a current sensor disposed between a battery and at least one electrical load. The current sensor is capable of sensing electrical current flowing from the battery to the load at a sensitivity sufficient to detect a current transient. The system also includes a controller in communication with the current sensor. The controller is capable of comparing the sensed current transient to a predetermined current transient for the load and signaling a fault when the sensed current transient and the predetermined current transient vary by a predetermined amount.

  • Patent number: 8461846
    Abstract: A method of estimating a state of charge of a battery in a vehicle undergoing a vehicle assembly process. The method may include the steps of: installing the battery in the vehicle; employing a sensor mounted in the vehicle to automatically sense battery net amp hours during at least a portion of the vehicle assembly process; storing the net amp hours in a control module mounted in the vehicle; mounting a data link connector in the vehicle to provide communication with the controller; temporarily connecting a tool connector of a battery test assembly to the data link connector and transmitting the stored net amp hours data to the battery test tool from the control module; and comparing the net amp hours to a predetermined maximum net amp hours to estimate if the state of charge of the battery is acceptable.
