Abstract
The system accurately measures a summation of the operations when an operating voltage is present. The system includes a capacitor charged by a supply voltage and a volatile memory register connected to receive the operating voltage signals to be measured and operable to store those signals as a measure of operations. A nonvolatile memory register is provided having stages corresponding to the stages of the volatile memory register. A store sequencing means is connected to be powered by the energy stored in the capacitor when the supply voltage is removed to transfer the count stored in the volatile memory register into the nonvolatile memory register. A means is provided for detecting when the supply voltage is applied, with a recall sequencing means operable in response thereto to transfer the count stored in the nonvolatile memory register into the volatile memory register.
