A computer-implemented method for determining resources utilized by a service request in a data processing system. The system utilizes a fast access non-volatile random access type main memory to store the programming for execution by the central processing unit. The conveyor belt is then moved relative to a plurality of magnetic sensors spaced apart and extending transversely relative to the conveyor belt. The processor processes the input signal using a gain. An electrical device such as a transistor or a diode can then be formed in each of the conductive regions.
