Abstract
Abstract A system for reading, recording and transferring one or more discrete machine events to computer processing equipment for accounting and tabulation. The system is comprised of a discrete machine event counting module which records and stores a count of machine operation, and can include means for recording the time of some selected event or events. The module also stores an identification code for the particular machine. The module can be connected directly through a microprocessor to a central processing center, or it can be located at a machine or at a group of machines. When located in an individual machine or in a group of machines, and hardwiring to the central processing center is for some reason not desired, then a portable transfer unit can be provided which can be connected to the module to retrieve or to read its contents by applying a read data command signal to the module. The transfer unit can then be transported to access means for the central processing center and the information that was obtained from the module will be transferred to centers for processing and tabulation.
