Embodiment Construction

[0066] figure 1 The device 1 exemplarily shown in is used in mobile parts 2 ( figure 2 ) A device that generates a pulse signal at a specific location called the trigger location.

[0067] Said moving part 2 experiences relative to a support 3 ( figure 2 ) relative movement.

[0068] Within the framework of the invention, the displacement (or movement) of the mobile part 2 relative to the support 3 and the object preferably corresponds to the movement of the mobile part 2 , the support 3 and the object being fixed. However, it may also be the case that:

[0069] – the object moves and the parts (called moving parts) are fixed; or

[0070] – Both moving parts and objects move.

[0071] In the framework of the invention, said mobile part 2 is capable of undergoing a relative movement according to N degrees of freedom, N being an integer greater than or equal to two.

[0072] An example is provided below, where N is equal to 6. Such as figure 2 As shown, the support 3 ...

Abstract

A generating device (1) comprises a unit (4) for generating triggering positions, a unit (5) for generating, during the course of the movement of the moving element, actual positions of said moving element, this unit (5) comprising a unit (6) for measuring successive effective positions of the moving element, the actual positions comprising at least these measured effective positions, a unit (8) for comparing, for a current triggering position, the actual positions successive to this current triggering position in such a way as to identify, among these successive actual positions, the closestactual position to said current triggering position, and this within a given limit, and a unit (10) for generating a pulsed signal for the current triggering position, if and when the moving element reaches said closest actual position and that this position is situated within the given limit.

Description

technical field [0001] The invention relates to a method and a device for generating a pulse signal at a position called a trigger position of a moving part. Background technique [0002] Typically (but not exclusively), the moving part undergoes a relative movement with respect to a fixed support such as eg a support plate (or platform) on which the object to be processed is provided. [0003] Typically, the relative displacement (or movement) of the moving part with respect to the support and the object to be processed may be generated by: [0004] – moving parts move, objects are fixed; [0005] – the object moves, the part called the moving part is fixed; or [0006] – Both moving parts and objects move. [0007] Moving parts often include handling systems. By way of example, processing systems include, but are not limited to, optical systems, mechanical systems, electronic systems, and / or other similar systems used in association with such processing systems. Such ...
