A method and system for installation of a monitoring unit. The monitoring unit comprises a photosensitive sensor for recording images of a monitored location. The system further comprises a light emitting element. The monitoring unit is arranged to detect the position of the light emitting element in a recorded image and by means of said position specify a sub-location within the monitored location.

System for installation

A method for simultaneous start-up of a plurality of processors in a multiprocessing system is disclosed, whereby a special hardware register (e.g., &ldquo;WhoAmI register&rdquo;) can be shared by the plurality of different processors. Alternatively, a separate WhoAmI register can be provided for one or more of the different processors. When a processor performs a read operation on a WhoAmI register, the register returns an identification number associated with that processor. Consequently, this processor can perform a set of test and jump instructions to access and execute the appropriate start-up code for this processor. Other embodiments disclosed include a method for distributing interrupts in a multiprocessing system, a method for bus arbitration in a multiprocessing system, and a method for creating atomic instructions that can be used for synchronization in a multiprocessing system.

System and method of start-up in efficient way for multi-processor systems based on returned identification information read from pre-determined memory location

The present invention relates to a method of manufacturing a two-part, thin-walled tubular element, particularly waveguides, to close tolerances. The inventive method comprises the steps of bending or pressing thin material in a manner to produce the parts (1, 2) of said element, wherein at least one of the parts (2) is provided with a shoulder-like projection (3) for joining said parts together; inserting the first part (1) into a first tool-half (4) which functions as a counter-pressure means and which has accurately determined internal dimensions; pressing the second part (2) together with the first part (1), wherein the formed element has a smaller vertical extension than the finished element; pressing a second tool-half (6) over the second part (2) and into abutment with the first tool-half (4), this second tool-half (6) functioning as a counter-pressure device and having accurately determined internal dimensions, wherein at least one of the tool-halves (6) is provided with means (7) which is operative in squeezing the join-forming surfaces of the element parts together into a lightly squeezed sealing connection; by introducing a foaming filler (8) into the assembled tool (4, 6) and between the element part (1, 2) and permitting the filler to expand so as to press the element parts outwardly against respective accurately-dimensioned tool-halves 4, 6); permitting the filler (8) to solidify to a core so that the element can be removed from the tool; sealing the lightly squeezed connection (3) to form a secure joint; and removing the foamed core from the finished tubular element.
