Abstract: An object detection system for a mobile machine is disclosed. The object detection system may have a first array of laser beam transmitters configured to generate a first plurality of grid lines on a ground surface, and a second array of laser beam transmitters configured to generate a second plurality of grid lines on the ground surface and produce a plurality of intersections with the first plurality of grid lines. The object detection system may also have a receiver configured to detect the plurality of intersections and generate a signal used to create an electronic terrain map based on the detection. At least one of the first and second arrays of laser beam transmitters may be selectively movable during operation to change a location of the plurality of intersections.

Abstract: The present invention provides apparatuses and methods for filtering a signal. A first processing device receives a first control signal and a first feedback signal and transmits a first error signal as a function of those signals. A second processing device receives the first error signal and transmits a second control signal as a function of the first error signal, a deadband, and a gain factor. A third processing device receives the second control signal and the first feedback signal and transmits an output signal as a function of those signals. A fourth processing device receives the output signal and transmits the first feedback signal as a function of the output signal to the first processing device and the third processing device, the first feedback signal being substantially equal to the output signal delayed by a first predetermined duration of time.
