A memory 1 performs its internal operation in response to access requests of a CPU 2 in synchronism with the oscillated output of a self-excited oscillator 102 incorporated therein and according to said access requests, and outputs a response request 103 for said access requests to said CPU in synchronism with its internal operation. Further, the invention relates to a method for collision detection of a coordinate measuring machine. The processor inputs a number load panel algorithms to the non-volatile memory after installation of the load panel and the processor in the load panel system.
