  • Patent number: 8957960
    Abstract: A machine vision system program editing environment includes near real time context generation. Rather than requiring execution of all preceding instructions of a part program in order to generate a realistic context for subsequent edits, surrogate data operations using previously saved data replace execution of certain sets of instructions. The surrogate data may be saved during the actual execution of operations that are recorded in a part program. An edit mode of execution substitutes that data as a surrogate for executing the operations that would otherwise generate that data. Significant time savings may be achieved for context generation, such that editing occurs within an operating context which may be repeatedly refreshed for accuracy in near real time. This supports convenient program modification by relatively unskilled users, using the native user interface of the machine vision system, rather than difficult to use text-based or graphical object-based editing environments.

    Abstract: A damping apparatus that supports and dampens a stage apparatus that positions and drives a stage to a target position is provided herein. The damping apparatus including a support plate part, a support force generating means, and a first controlling means. The support plate part supports the stage apparatus. The support force generating means exerts a damping action by applying a support force to the support plate part in the vertical directions. The first controlling means uses the acceleration of the stage, which is derived from a target track, to the target position, to control the support force generated by the support force generating means so as to compensate for forces that both occur as a result of the acceleration of the stage and cause the support plate part to tilt. The present invention controls vibration and the tilt of a base plate with high precision.

    Abstract: Methods provide for the controlled application of forces to a structure during leveling and securing procedures. According to embodiments described herein, a structure is supported at a number of support locations. An upward force is applied to the structure by the force application devices to counteract an equivalent downward force from the structure at each support location. The forces applied by the force application devices are monitored to detect whenever one or more of the upward forces deviates outside of a threshold range of force values, which includes a quantity of force sufficient to counteract internal forces within a material of the structure. Each force may be adjusted to ensure no deviation outside of the allowed threshold range.

    Abstract: A mechanical system selectively imparts a prescribed motion to an output load using two or more actuators, including at least one having an active material element. The output load can be a locking member when the system is a vehicle transmission, a shuttle car of a linear system, or another device. A controller determines a total motive force required for imparting the prescribed motion, and selectively commands a combination of the actuators to provide the total motive force, apportioning the total motive force between the various actuators to optimize the performance of the system. An algorithm determines which combination of the actuators is the most suitable in moving the output load, and continuously modified this combination as needed as the output load is moved. The other actuator or actuators are then selectively energized as needed to provide the total motive force depending on this suitability determination.

The second controller determines, from the inputs, an adapted control output to the stage. The adaptive transfer-function can be, e.g., an AFC transfer-function producing an AFC controlled output or an ILC transfer-function producing an ILC controlled output.

  • Patent number: 7689299
    Abstract: The invention is provided with means for detecting a situation of rotating a rotary work lifter at any time, and a determining portion for determining whether operation of the rotary work lifter is to be stopped by a state of rotating the rotary work lifter detected by the means, thereby, operation of the rotary work lifter can be stopped when rotation of the rotary work lifter is interrupted by pinching a work piece or the like between the rotary work lifter and a working table or the like, or when the rotation is interrupted by some other influence. Therefore, the rotary work lifter, the working table or the like can be prevented from being finally destructed by continuing to generate a torque by a drive source even after interrupting rotation of the rotary work lifter as in a background art.

  • Patent number: 7664557
    Abstract: To facilitate an intuitive operation of an adjustable device of a medical apparatus, a system for the automatic setting of an operating configuration of the portable control module controlling the adjustable device is provided. Different operating configurations regarding the directional control of the movement of the movable device differ are based on the relative spatial position of the adjustable device with respect to the control module. The system includes at least one signal sender unit for sending a signal. The signal sender unit may be arranged on the control module. The system further includes at least two signal converter units for converting and retransmitting or for converting and reflecting the signal. The signal converter units may be arranged on different positions on the device. A signal receiver unit is used for receiving the converted signal, and the receiver unit may be arranged on the control module.

  • Patent number: 7657334
    Abstract: A lithographic apparatus includes a movable part and a controller to control a position quantity of the movable part. The controller includes a first controller transfer function and a second controller transfer function. A selector selects the first controller transfer function or the second controller transfer function depending on a state of the movable part. The first controller transfer function may be chosen in a substantially stationary state of the movable part, while in a substantially non-stationary state of the movable part, the second controller transfer function may be chosen.

  • Patent number: 7606625
    Abstract: A method for aligning a stent with a stent support includes the steps of (1) placing a stent support and a stent mounted on the stent support in a vertically position with the stent support's first support element at a lower position and the stent support's second support element at an upper position; (2) obtaining a digital image of the stent support and stent; (3) analyzing the digital image of the stent support and stent to compute the vertical position of the stent's upper end; (4) computing a desired position of the second support element based on the position of the stent's upper end; and (5) using a positioning device to move the second support element to the desired position. The movement of the second support element causes the conical sections of the first and second support elements to engage the respective ends of the stent to center the stent around a core element of the stent support and to secure the stent in a longitudinal direction of the stent support.
