The PROM generates a direct-current analog signal that drives a speedometer displayed on one scale of a dual-movement meter. The heart of the system is a programmable read-only memory (PROM) that has the required test profiles permanently recorded on plug-in cards, one card for each different driving schedule. These schedules require operating an electric vehicle in a selected stop-and-go driving cycle and repeating this pattern until the vehicle ceases to meet the requirements of the cycle.

Savannah River Lab., Aiken, SC (United States).It replaces more traditional but troublesome selection methods, such as the drawing of cards from a holder. The use of the randomizer eases selection, ensures that it is fair and meets the DOE-specified percentage, and rules out most forms of tampering or subterfuge which might otherwise be used to gain entry without a search. The probability of selection is inversely proportional to the number of states, which is programmable, and is unaffected by the results of previous cycles. One of these states signals STOP FOR INSPECTION through a red light and buzzer each of the others signals PASS - O.K.

Passage of an entering person's hand over a sensor starts an oscillator, which cycles among several electronic states for a few seconds, then stops in one of them and generates an output signal. An electronic random selector has been developed which is self-contained, rugged, compact, tamper-resistant and easy to operate. This paper reports that enhanced DOE security requirements at contractor sites now include random searches of a specified percentage of entering personnel, using a metal detector.
