Timing system and device and method for making the same
First Claim
1. A timing device for monitoring a time period comprising:
- a. a first reactive zone for indicating a first time period;
b. a second reactive zone separated from and independent of the first reactive zone and indicating a second time period, wherein the first reactive zone and the second reactive zone viewed collectively indicate passage of a total time; and
c. an activation mechanism for activating the timing device.

Abstract
A timing device for indicating the passage of a duration of time is disclosed. The timing device and system, in accordance with the embodiments of the invention, comprise an electrochemical component which generates a visual and/or audio indication of the passage of time. The timing device further comprises a compensating element, such as a varistor, a thermistor and/or combinations thereof. The compensating element regulates the response of the device with respect to changes in temperature. The timing device is configured to indicate the passage of a single duration of time or comprises zones that are activated in a range of prescribed times and individually or collectively indicate the passage of time or the passage of a range of times.
