Patent EP-0237897-A2 (EP)
Inventor: SCHMIDBAUER HELMUT
IPC: B23K9/20
Filed: 1987-03-07
Abstract: In a stud-welding gun for attaching studs or pin-shaped parts by welding, the welding piston is formed from two parts rigidly connected to one another, namely from an essentially circular-cylindrical front piston part and from an elongated rear piston part roughly rectangular in cross-section. In addition, steps are formed on the top side, remote from the trigger, of the rear piston part, with which steps an actuating part interacts which is pivotably held in the gun housing and on which the trigger acts. Furthermore, the rear piston part, roughly rectangular in cross-section, is guided in such a way as to be locked in terms of rotation in diametral longitudinal slots of a sleeve enclosing the front piston part. The sleeve in turn is held at its end facing the stud holder in such a way as to be locked in terms of rotation by pins projecting into the gun housing, these pins engaging in diametrically opposite slots provided at this end. <IMAGE>

Abstract: Tasks may be planned for execution on a single processor or are split up by the designer for execution among a plurality of signal processors. The tasks are modeled using a design aid called a precedence graph, from which a dependency table and a prerequisite table are established for reference within each processor. During execution, at the completion of a given task, an end of task interrupt is provided from any processor which has completed a task to any and all other processors including itself in which completion of that task is a prerequisite for commencement of any dependent tasks. The relevant updated data may be transferred by the processor either before or after signalling task completion to the processors needing the updated data prior to commencing execution of the dependent tasks. Coherency may be ensured, however, be sending the data before the interrupt. When the end of task interrupt is received in a processor, its dependency table is consulted to determine those tasks dependent upon completion of the task which has just been signalled as completed, and task dependency signals indicative thereof are provided and stored in a current status list of a prerequisite table. The current status of all current prerequisites are compared to the complete prerequisites listed for all affected tasks and those tasks for which the comparison indicates that all prerequisites have been met are queued for execution in a selcted order.

Abstract: The device employs a head-up display which is mirrored as a virtual image in the field of view of the vehicle user. The operating parameter is steady in the head-up display, i.e. it does not move, and changes only under particular preconditions, and is precisely represented on a display instrument represented outside the field of view. The vehicle user thus obtains a relevant statement in the head-up display without, however, having his field of view disturbed by a continually changing display of information. <IMAGE>
