Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
100 words
A method of counting impulses emitted by impulse transmitters, comprising the following steps: A. assigning a partial address to each impulse transmitter, B. feeding the partial addresses into a control unit, C. adding the partial addresses to one of two base addresses in said control unit to form a sum address, D. feeding into a ''''1'''' adder the contents of those memory cells of a process calculator, the address of which is identical to said sum address, E. increasing said contents by ''''1'''' in said ''''1'''' adder and F. storing the increased contents in their respective previous same memory cell.
Claim 2
Independent Claim
100 words
A method of counting impulses emitted by impulse transmitters, comprising the following steps: A. assigning a partial address to each impulse transmitter, B. feeding the partial addresses into a control unit, C. adding the partial addresses to one of two base addresses in said control unit to form a sum address, D. feeding into a ''''1'''' adder the contents of those memory cells of a process calculator, the address of which is identical to said sum address, E. increasing said contents by ''''1'''' in said ''''1'''' adder and F. storing the increased contents in their respective previous same memory cell.
Claim 3
Dependent Claim
63 words
A method as defined in claim 1, including the steps of A. applying time impulses to a counter, B. applying a command signal to said control unit from said counter when the latter reaches a predetermined counting stage and C. adding said partial addresses to the other of said two base addresses in said control unit upon receipt thereby of said command signal.
