Abstract: A system and method are provided for optical beamforming and interferometry using digital source modulation. In one aspect, a digitally-modulated calibration signal is included in the optical target source, for use by receiving mirrors and equipment to continuously lock onto, track, and remove atmospheric and instrumental temporal distortion effects.

Abstract: A multi-head centerless belt grinder for removing material from a workpiece includes a common base and a plurality of grinding heads spaced apart from one another and mounted to the common base. Each grinding head includes a moveable work rest blade, a moveable regulating wheel and a moveable grinding belt positioned by servomotors to centerless grind the workpiece along a common axis of rotation. The grinder is programmable for rapid machine changeover and set-up typically within 2-5 minutes to accommodate a large range of workpiece diameters. This feature results in improved productivity and output as well as greater flexibility for scheduling numerous workpiece diameters within a normal eight-hour work shift. A trough may extend beneath and between each of the grinding heads to more efficiently collect and transfer grinding swarf generated during the grinding process to a filter operable to separate solids within the swarf from coolant.

Abstract: An electromechanical machine includes a stator. A rotor is configured to rotate relative to the stator about a rotational axis. A coil extends about the axis and is wound on a bobbin. The bobbin surrounds the axis and has a circumferentially extending pocket in which the coil is located. The bobbin further has a circumferentially-extending overhang section that extends directly over at least a portion of the coil.

Abstract: A stacked three head finishing apparatus is provided. The apparatus includes a base mountable to a floor, a first head mounted to the base, a second head mounted to the base above the first head, and a third head mounted to the base above the second head. Each of the first, second, and third heads includes a rotatable wheel. A motor imparts rotation to the wheel which may then be used for finishing operations. The height of each head above the floor and the position relative to one another is pre-selected to ensure that all of the heads are within reach of a robot arm and to ensure that nothing will interfere with the movement of the robot arm.

Abstract: A direct clamp robotic finishing system is provided including a robot, a gripper secured to the robot, and a pair of fingers secured to the gripper. A tray assembly is also provided for supporting a plurality of implants for picking up by the fingers. An implant reorientation station is provided for supporting the implant being maneuvered by the robot as the robot re-grips the implant from a new direction. The fingers directly clamp the implant thereby eliminating the need for dedicated implant support bars.

Abstract: A multi-spindle end effector is provided for a multiple axis robot. The multi-spindle end effector includes a plate housing having at least a pair of spaced-apart spindles mounted thereon. A servo-motor drivingly engages the spindles. A gear box steps down the RPMs of the motor to the desired RPM of the object to be rotated. A timing belt, which may be continuous, interlinks the first and second spindles so that the rotation of first spindle matches the rotation of the second spindle. An idler pulley may be employed to properly tension the belt.
