Abstract: A mold structure used in an injection molding process to form a cup having broken threads where an “A” and “B” mold form a horizontal irregular parting line to alleviate stripping or unscrewing along the threads. The “B” mold includes a series of segmented surfaces arranged in a helical pattern at an angle from a transverse plane and extending around a longitudinal axis to form a topside surface of the “B” mold. The “A” mold having a series of corresponding segmented surfaces similarly constructed and arranged to mate with the “B” mold. Closed-ended flutes are disposed on an inner wall surface of each segmented surface on either the “A” or “B” mold. A core insert is disposed within but having a space thereinbetween inner wall surfaces of the top and “B” mold and abutting the closed “A” mold portion and closed “B” mold portion creating a seal off.

Abstract: A method for segmenting an input volume in accordance with at least one selected characteristic comprises the steps of casting a plurality of rays along a plurality of views of the input volume, identifying regions corresponding to the selected characteristic within each ray, and processing the identified regions to generate an output volume indicating regions having the selected characteristic.

Abstract: The present invention is directed toward providing interactive haptic collision detection between a stationary and a moving object in a virtual reality environment. A user grasps the arm of a haptic device and manipulates an object as viewed on a virtual reality display. As any portion of the manipulated object comes too close to the surface of the stationary object, the haptic device imposes feedback forces against the user's efforts that increase in magnitude as the user manipulates the object beyond a force boundary proximate to the surface of the stationary object. The feedback forces are applied directionally in line with the shortest path between the surfaces at risk of collision. Several measures can be implemented by the user to reduce the computation load involved in constantly comparing the distances between points on the surface of the movable object and points on the surface of the stationary object without seriously compromising the collision detection and avoidance functions of the system.

Abstract: An analytical method for determining a cable occupancy volume includes obtaining a cable length and identifying a number and location of a plurality of cable supports for supporting the cable along its length. The cable occupancy volume that is generated is based on the cable length, the number of supports and the location of the supports. The instructions for practicing the method are encoded on a computer-readable storage medium.

Abstract: The invention is embodied in a method of controlling a robot manipulator moving toward a target frame F.sub.0 with a target velocity v.sub.0 including a linear target velocity .nu. and an angular target velocity .omega..sub.0 to smoothly and continuously divert the robot manipulator to a subsequent frame F.sub.1 by determining a global transition velocity v.sub.1, the global transition velocity including a linear transition velocity .nu..sub.1 and an angular transition velocity .omega..sub.1, defining a blend time interval 2.tau..sub.0 within which the global velocity of the robot manipulator is to be changed from a global target velocity v.sub.0 to the global transition velocity v.sub.1 and dividing the blend time interval 2.tau..sub.0 into discrete time segments .delta.t. During each one of the discrete time segments .delta.t of the blend interval 2.tau..sub.0, a blended global velocity v of the manipulator is computed as a blend of the global target velocity v.sub.0 and the global transition velocity v.
