Abstract: A system for displaying machine surroundings to an operator in a cab of the machine may include at least one outward-facing camera mounted on the machine. The at least one outward-facing camera may be configured to generate image data for an actual environment surrounding the machine. The system may also include at least one operator-facing camera mounted within the cab of the machine. The at least one operator-facing camera may be configured to determine gaze attributes of the operator. A sensor may be mounted on the machine and configured to generate object data regarding detection and ranging of an object in the actual environment.

Abstract: A system for detecting when a gas concentration sensor has drifted or failed is disclosed. The system has a first gas concentration sensor configured to detect a first gas concentration and generate a corresponding first signal. The system also has a second gas concentration sensor configured to detect a second gas concentration and generate a corresponding second signal. In addition, the system has a controller in communication with the first and second gas concentration sensors. Based on the first and second signals, the controller is configured to provide an out-of-tolerance gas concentration sensor warning.
