Abstract: Disclosed are systems and methods for assisting with procedures involving a subject's joint, such as a joint. Robotic devices move and position the subject to manipulate the joint and sensing devices sense the joint gap. The robotic devices are controlled based on the joint gap. Novel techniques are disclosed for joint gap segmentation, approximating an uncertainty in determination of the varying dimension of the joint gap, and real-time motion analysis of the joint gap size. In some examples, a kinematic model of the patient's anatomy is utilized to provide robotically assisted manipulation of the same using the techniques described herein.

Abstract: This invention concerns digital terrain mapping, and in particular a method for producing digital terrain maps of the vicinity around large rotating machinery, such as draglines, shovels, excavators, wheel loaders or cranes. The method involves the following steps: Mounting a 2-Dimensions laser scanner and a high-accuracy RTK GPS system to an item of large rotating machinery, at a radial extremity of the machinery. Arranging the laser scanner to record radial lines of data representing the terrain below the extremity of the machinery. Rotating the machinery completely about its axis of rotation and generating data from both the laser scanner and GPS system that represents the terrain around the machinery.

Abstract: A navigation system for navigating an autonomous vehicle along a path that is confined by walls that are within range of on-board sensors is described. The system determines the relative location and orientation of the walls with respect to the vehicle. The system controls the steering angle and the ground speed of the vehicle by employing: (a) range data to establish free space in front of vehicle; (b) active contours to generate a desired path; (c) driving hints to guide the active contours along arcs and open areas; (d) steering hints to confine the active contours to a specific domain of free space, at, for instance, intersections; and (e) a desired path to generate steering demand or velocity.
