Abstract: In a mobile equipment with an articulated front portion having a worktool, a fisheye camera with a wide field of view, containing the front portion, is often mounted in a fixed direction on a rear portion of the mobile equipment. Thus, when the front portion moves (e.g., rotates) relative to the rear portion, a view around the front portion may be compromised due to inherent cropping in fisheye-distortion correction. Digital panning of panoramic video is disclosed that rotates a projection surface, in accordance with movement of the front portion, and generates a projected video on the projection surface, utilizing information that may have otherwise been cropped, to expand the visible area around the worktool. The digital panning in the projected video may mimic an operator turning their head to look down the longitudinal axis of the front portion while using the worktool.

Abstract: A power system is disclosed for use with a mobile machine having a work tool. The power system may have an engine, a first input device configured to generate a first signal indicative of an operator-desired output of the engine, a second input device configured to generate a second signal indicative of an operator-desired movement of the work tool, and a controller in communication with the engine, the first input device, and the second input device. The controller may be configured to adjust fueling of the engine based on the first signal and based on a desired speed of the engine during a first mode of operation, and to adjust fueling of the engine based on the first signal and a desired torque of the mobile machine during a second mode of operation. The controller may be further configured to selectively switch operation of the machine between the first and second modes based on the second signal.

Abstract: In some implementations, a controller of a machine may receive an indication of performance, by the machine, of a loading operation associated with a material. The controller may determine, based on the indication, a physical location associated with the loading operation. The controller may identify, based on the physical location, prior loading operation data. The controller may determine, based on the prior loading operation data, estimated identification information associated with the material. The controller may cause, based on the estimated identification information, one or more actions to be performed.
