  • Publication number: 20240239192
    Abstract: The mobile device is provided with an operation restriction unit, and the operation restriction unit determines which seat of the vehicle is being operated from the captured image of the back camera. When determining that the captured image is captured by the driver's seat, the operation restriction unit restricts the operation of the process execution unit. Accordingly, in the mobile device, it is possible to prevent the mobile device from being operated in the driver's seat, which is appropriately restricted from being operated in the driver's seat in a vehicle or the like.

  • Publication number: 20240185026
    Abstract: Methods and systems for defect detection include determining a first residual score by comparing a first predicted system state, determined according to previously measured environment data, to an actual system state. A second residual score is determined by comparing a second predicted system state, determined according to previously measured system state data, to the actual system state. A defect score is generated based on a difference between the first residual score and the second residual score. An automatic action is performed responsive to a determination that the defect score indicates a defect in system behavior.
