  • Patent number: 4652139
    Abstract: An electronic non-volatile elapsed time meter useful for generating elapsed time information when connected in parallel with an input supply voltage supplying power to a power driven device. Visual readouts are continuously generated during time of use of the input supply voltage and accumulated intervals of time of use are stored in a non-volatile memory when power is removed from the device. Upon a later resumption of power usage, the stored non-volatile data is retrieved, displayed and summed with the new generated elapsed time information. This meter is applicable to both AC and DC operations.
