Abstract: A hydraulic actuator with a sensor mounted on the actuator cylinder for determining the position of the actuator. The arrangement comprises a hydraulic actuator which includes a cylinder having a bore in which a piston is slidably mounted for movement along the cylinder to extend and retract the hydraulic actuator. The cylinder has a side wall and a cylinder aperture extending through the side wall. A wire actuated encoder is mounted on the external surface of the cylinder, which has a wire which extends through the cylinder aperture and is attached to the piston for determining a stroke position of the piston within the cylinder.

Abstract: An imaging system for a machine having an implement includes at least two cameras mounted on the machine at opposing sides of the implement and configured to generate at least two camera views of an environment of the machine, and a processing device in communication with the at least two cameras. The processing device is configured to obtain the at least two camera views, obtain at least one of a position or an angle of the implement, determine at least one of a position or an angle of a stitching line according to the at least one of the position or the angle of the implement, and generate a stitched surround view based on the at least two camera views and the stitching line.
