A system for performing the method of this invention includes a leader having a robot arm able to articulate about first axes and supporting an end effector. A follower includes a robot arm able to articulate about respective second axes. Servo motors articulate the leader arm about the first axes and the follower arm about the second axes. A user interface allows a user to jog the arm of the leader and to program movement of the arms for automatic execution such that the end effector reaches predetermined positions. A controller, operatively connected to the servo motors and the user interface, controls operation of the servo motors, moves the arm of the leader in accordance with the programmed movement, and moves the arm of the follower such that it tracks or mirrors movement of the leader.

An anti-pinch control system is used to identify obstructions in a path of movement for a powered vehicle member, such as a vehicle window for example. A pinching area is identified for the vehicle window and at least one indicium or indicator is mounted to a vehicle structure to be in view of a camera. The indicium is positioned such that no object may pass into the pinching area without also passing between the camera and at least a portion of the indicium. The camera identifies an obstruction when any portion of the indicium is obscured. This indicium includes a plurality of predefined zones, with each zone being associated with an operational function, such as upward window movement, downward window movement, door locking, side mirror movement, etc. This eliminates the need for separate switches to perform each of these functions thereby reducing overall cost for a vehicle door system.

System and method for synchronizing the low speed mirror movement of a mirror display system with incoming frame or video signals, and synchronizing buffered lines of video data to the independently oscillating scanning mirror. According to one embodiment of the invention, the peak portions of the low speed cyclic drive signal are synchronized with the incoming frames of video by compressing or expanding the peak portion or turn around portion so that each video frame begins at the same location on the display screen. The actual position of the high frequency mirror is determined by sensors and a “trigger” signal is generated to distribute the signals for each scan line such that the scan lines are properly positioned on the display.

The invention is directed to an arrangement for generating a pulsed laser beam with high average output, in particular for generating a hot plasma which emits extreme ultraviolet (EUV) radiation. It is the object of the invention to find a novel possibility for generating a laser beam with a high repetition rate and average output which allows the repetition frequency and, therefore, the output of the laser system to be increased by connecting together a plurality of individual lasers having limited repetition rate without degradation of the beam quality on the target compared to that of an individual laser. This object is met, according to the invention, in that an oriented mirror surface is associated with each individual laser in such a way that a beam bundle which is emitted by each individual laser so as to be offset with respect to time and which is reflected at the mirror surface is coupled into a common beam path, and laser pulses in the common beam path are directed to a target one after the other in a regular, defined pulse sequence, and, with a continuously dynamic mirror movement for coupling the laser pulses into the common beam path, optical means are provided in the common beam path for compensating the directional change caused by the mirror movement.
