Abstract
Abstract AN ELAPSED TIME COMPILING SYSTEM IS DESCRIBED WHICH INCLUDES ELAPSED TIME MONITORS, EACH FOR MEASURING THE AMOUNT OF USE OF AN ITEM OF EQUIPMENT, AND A COMPILER FOR SEQUENTIALLY READING AND STORING OUTPUT SIGNALS FROM EACH SUCH MONITOR ALONG WITH AN IDENTIFICATION SIGNAL REPRESENTING THE PARTICULAR EQUIPMENT ITEM TO WHICH IT CORRESPONDS. IN A PREFERRED EMBODIMENT, THE READING OF EACH OUTPUT SIGNAL BY THE COMPILER RESETS THE MONITOR TO ZERO, THEREBY COMPLETELY PREVENTING ERROR ARISING FROM READING THE SAME MONITOR MORE THAN ONCE.
