Abstract: An Analog/mixed signal automatic test system includes a software architecture that creates a virtual composite instruments through novel software dynamic allocation of low level resources. These virtual composite instruments provide backwards and forwards compatibility to a variety of automatic test equipment, known or available on the market. The virtual composite instruments are free from the normal constraints imposed by hardware implementations. Creation of the virtual composite instruments allows a single piece of automatic test equipment system to emulate many implementations of automatic test equipment, providing higher utilization, and therefore a lower cost test solution for device manufacturers. The test instruments are preferably object controls and are preferably instantiated and controlled by the test system server. This allows multiple users to control the tester simultaneously across, for example, the Internet.

Abstract: A mechanism for providing a cycloidal output motion for an output member in a linear direction using a constant velocity rotary input motion driving an off-center input shaft and drive gear and utilizing a secondary motion to influence the position of the drive gear in relation to the output member and the acceleration and deceleration of the output member. A compact embodiment utilizes a ring gear and planetary and a reaction motion to provide the secondary input.

Abstract: A milling machine for cutting a surface on a workpiece and including a milling head assembly having a cutting stroke for cutting the surface of the workpiece and a return stroke to prepare for the next cutting stroke, the milling head assembly including a rotatable spindle structure with a cutter structure mounted to the spindle structure for rotation therewith and being actuable to provide a desired cut on the workpiece surface and a piston and cylinder construction operatively connected with the cutter structure to axially position the cutter structure separately from the spindle structure between an advanced position to provide a desired cut on the workpiece surface and a retracted position relative to the workpiece surface to preclude cutting engagement with the workpiece surface as the cutter structure is moved in opposite directions traversing the workpiece surface and a unique method providing a rough cut on the workpiece surface when the cutter structure is in the retracted position and a finish cut w
