  • Patent number: 11508073
    Abstract: A method for determining an angle of a tip of a ripper shank includes a controller receiving an input command. The controller estimates an angle of the tip based on one or more parameters of the input command. Further, the controller acquires a video feed of the ripper shank and detects an object in the video feed. The controller identifies the object as one of the ripper shank or a component movable with a movement of the ripper shank based on a match of a color of the object to a predefined color and a match of a profile of the object to a predefined profile. The controller co-relates the profile to an angular value in a map table and sets the angular value to be an actual angle of the tip over the angle of the tip estimated based on the input command.

  • Patent number: 7320220
    Abstract: A valve arrangement for an internal combustion engine is disclosed. The valve arrangement may have a housing at least partially defining a venturi passageway, a first port disposed at an entrance to the venturi passageway, and a second port disposed at a throat of the venturi passageway. The valve arrangement may further have a valve element disposed within the housing to regulate the flow of fluid through the housing, and a sensor mounted to the housing in communication with the first and second ports. The valve arrangement may also have a controller mounted to the housing in communication with the sensor. The controller may be configured to affect movement of the valve element in response to input from the sensor.
