Timing system and device and method for making the same
Abstract:
A timing device comprises an electrochemical timing structure and a mechanism that enables the timing device to be manually programmed to expire at a plurality of different time periods. In some embodiments, the mechanism is used to adjust the timing device to add a duration of time to an expiration time of the timing device. Alternatively the mechanism is used in order to subtract a duration of time from an expiration time of the timing device.
