Timing system and device and method for making the same

摘要

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.

1. An adjustable timing device, comprising:
a. an electrochemical timing structure; and b. a mechanism that changes an external characteristic of the timing device and that is manually adjustable by one of adding a component to the timing structure or subtracting a component from the timing structure in order to adjust an expiration time of the timing device, wherein after activation, a depletion of the timing device is viewed through a lens.
