  • Patent number: 12020487
    Abstract: Changes in ambient light intensity are detected by processing image data from an image capture device to determine, iteratively, a signal-to-noise ratio of the image data. The signal-to-noise ratio is a ratio of average to variance of pixel values for some of the pixels forming the image. A control output is generated, based on the signal-to-noise ratio, that is responsive to changes in ambient light intensity. The control output is used control a light source of a vehicle.

  • Patent number: 11542685
    Abstract: A method for providing display redundancy on a machine is provided. The machine includes a first display configured to perform a first set of functionalities associated with one or more operations of the machine and a second display configured to perform a second set of functionalities associated with the one or more operations of the machine, the second set of functionalities being different from the first set of functionalities. The method includes detecting, by a controller, failure of the first display. The method further includes executing, by the controller, at least a subset of the first set of functionalities on the second display along with at least a subset of the second set of functionalities, when the failure of the first display is detected.

  • Patent number: 10636225
    Abstract: A method for operating a machine adapted to transport a load during a work cycle is disclosed. The method includes determining a first stationary state of the machine, and causing sensors to start transmission of first signals. The first stationary state corresponds to a first segment of the work cycle, and the first signals indicate a weight of the load during the first segment. Further, the method includes determining a moving state of the machine corresponding to a second segment of the work cycle, and causing the sensors to terminate transmission of the first signals. Furthermore, the method includes determining a second stationary state of the machine, and causing the sensors to start transmission of second signals. The second stationary state corresponds to a third segment of the work cycle, and the second signals indicate a weight of the load during the third segment.

  • Patent number: 9625036
    Abstract: The present disclosure relates to a vehicle having a braking system and a method of engaging the braking system. The braking system engages a brake mechanism as a waiting brake. The vehicle has a dual function device which is configured such that when the dual function device is activated when the vehicle transmission system is in a drive mode, the transmission system is maintained in that drive mode, and when the dual function device is activated when the transmission system is in the neutral mode, the brake mechanism is engaged.

  • Publication number: 20150321648
    Abstract: The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system comprises first and second brake mechanisms. A controller is configured to control the operation of the second brake mechanism such that, if a predetermined fault condition is determined whilst the first brake mechanism is engaged, the controller automatically engages the second brake mechanism.

  • Publication number: 20150323070
    Abstract: The present disclosure relates to a braking system and, more particularly, to a braking system for engaging a brake mechanism as a waiting brake for a load carrying vehicle. The braking system utilises an electrohydraulic brake control mechanism comprising at least one automatic retard control valve to engage the brake mechanism, which is activated by a dual function apparatus which also controls another operation of the vehicle.

  • Publication number: 20150323069
    Abstract: The present disclosure relates to a method of disengaging a brake mechanism used as a waiting brake for a load carrying vehicle. In a vehicle comprising an automatic transmission system having at least one drive mode and a neutral mode, changing the mode of the transmission system from neutral mode to a drive mode automatically disengages the brake mechanism.
