Abstract: A method for generating a three dimensional grid of terrain includes receiving data representing a three-dimensional point cloud and generating a plurality of slices of the data. The method evaluates the slices using a swarm intelligence algorithm. The method is able to identify both terrain and objects. The terrain can also be identified as traversable terrain.

Abstract: A control system for a mobile machine is disclosed. The control system may have a first sensor mounted on the mobile machine and configured to capture a first image of a region near the mobile machine, a second sensor mounted on the mobile machine and configured to capture a second image of the region, and a controller in communication with the first and second sensors. The controller may be configured to generate a stereo image from the first and second images, compute a disparity map of the stereo image, and generate an output to affect operation of the machine when a density of the disparity map is less than a threshold density.

Abstract: The present disclosure is directed to a system for controlling a plurality of machines. The system includes a camera disposed on a second machine and configured to record at least one image of a first machine. A controller is configured to be in communication with the first machine and the second machine. The controller is configured to track information associated with the recorded image of the first machine. The controller is also configured to determine a direction of movement of the second machine based on an analysis of the tracked information.

Abstract: A method and apparatus for providing an audible alarm signal. The method and apparatus includes creating a rectangular pulse signal having a desired period and a desired first amplitude, adding a shaped modulation component to the rectangular pulse signal from the desired first amplitude to a desired second amplitude to create a modulating waveform, creating a carrier signal, and combining the carrier signal and the modulating waveform to create the audible alarm signal.

Abstract: A drive arrangement (62) for transferring rotational motion from a pin (44) of a draft arm (14,16) of a hitch assembly (10) to a position sensor (64). The drive arrangement (62) includes a driver (68) that acts as a wear compensation mechanism (66).
