Abstract: The present invention is a weight exercise machine for use by a user. The machine comprises an exercise member, a plurality of weights, and an index. The user exerts an exercise force against the exercise member when using the machine to exercise. The index is rotated to operably couple the exercise member to at least one of the weight plates such that the displacement of the exercise member causes the at least one of the weight plates to displace. The plurality of weight plates includes a first weight plate type and a second weight plate type having configurations and masses that differ. The index allows selection of different combinations of weight plates for operable coupling to the exercise member.

Abstract: A leg press exercise machine comprises: a frame; a seat unit attached to the frame; a press mechanism attached to the frame, the press mechanism including a foot panel and at least one swing link pivotally interconnected with the frame; a resistance-imparting unit operatively connected with the press mechanism; and a resistance coupling mechanism attached to the press mechanism and the resistance-imparting unit. The press mechanism is configured such that the foot panel is movable along a generally longitudinal stroke path between a retracted position and a fully extended position. The resistance-imparting unit provides resistance to the foot panel as it moves from the retracted position to the fully extended position. The resistance coupling mechanism includes a drawing link pivotally interconnected with the swing link and a control link pivotally interconnected with the drawing link and the press mechanism. The control link is further attached to the resistance-imparting unit.

Abstract: A robot programming system is provided comprising a simulated work cell configuration, a tool position and orientation sensor assembly, and a programing computer. The simulated work cell configuration includes a tangible artificial tool and a tangible artificial workpiece, wherein the position and orientation of the artificial tool relative to the workpiece is variable. The sensor assembly is operative to sense the position and the orientation of the artificial tool. The programming computer is in communication with the sensor assembly and is programmed to (i) display a variable virtual robot configuration based upon the sensed position and orientation of the artificial tool, (ii) receive discrete artificial tool positions and orientations from the sensor assembly, and (iii) create a robot job data file including the discrete artificial tool positions and orientations.

Abstract: Methods for applying graph theory techniques in methods to establish multiplexed assay formats for analyzing polymorphic DNAs are provided. These methods are used for designing and carrying out rapid and efficient processes for distinguishing target polymorphic DNA segments on the basis of variations in sequence and/or length. The methods are thus useful in the design of assays for determining identity, ancestry, predisposition to disease, or the presence or absence of a desired trait; genetic linkage analyses (gene mapping); and drug development.

Abstract: A three-dimensional vision seam tracking method and apparatus for controlling the motion of the center point of a tool mounted on a manipulator. The manipulator is provided with a control to operate the manipulator members to move the tool center point at programmed velocities along a programmed path corresponding to the seam. The manipulator is provided with a vision system including a laser scanner/camera head mounted ahead of the function element. The control is programmed with dynamically varying orientation angles to control the orientation of the tool during seam tracking. The laser scanner/camera head scans the seam at predetermined time intervals. A set of coordinates for the center point of the seam in a coordinate system relative to the camera is provided for each scan.

Abstract: A machine and control are provided for effecting motion of a function element, such as an adhesive material dispensing gun, and controlling the operation of the function element by means of a control signal proportional to the velocity of a workpoint associated with the function element. The control produces a velocity signal representing the velocity of the workpoint, calculates the value of a control signal using the velocity signal and predetermined constant defining the constant of proportionality and zero velocity output and applies the control signal to a digital-to-analogue converter to produce an output signal for controlling the function element.

Abstract: A method of positioning a tool along a circular arc. The tool is carried by an automaton which is moved through a teaching phase during which it is taught coordinates and wrist orientation angles for three reference points. The method then proceeds into a work phase in which calculations are performed to determine coordinates and wrist angles for a series of work points spaced along the circular arc defined by the three reference points. Thereafter the automaton is direction to position the tool at the calculated coordinates and orientations.
