1. A timing device comprising:
- a. a first timing component comprising a first indicator for indicating a cumulative time period; and
b. a second timing component comprising a second indicator for indicating a second time period comprising a time that the timing device has been exposed to a predefined temperature during the cumulative time period,wherein the first timing component and the second timing component are independently activated, and wherein the second timing component is automatically activated by the ambient temperature reaching the predefined temperature.

Abstract
A timing device that includes an anode layer, a cathode layer and an electrolyte attached to a base layer. The anode layer and the cathode layer are placed adjacent to one another along an axis of the timing device. Upon activation of the timing device the anode layer is depleted away from the cathode layer until the timing device is fully expired. Once the timing device is expired, a change is seen indicating that the timing device has expired. In some embodiments, a color change indicates that the timing device has expired. In some embodiments, as the timing device expires electronically readable information is uncovered.

21. A timing device comprising:
-
a. a first timing component comprising a first indicator for indicating a cumulative time period comprising; i. an anode layer; ii. a cathode layer; iii. a base layer; iv. an electrolyte attached to the base layer; and v. an activator to activate the timing device, wherein upon activation of the first timing component, the anode layer depletes in a direction away from the cathode layer and a first electronically readable information is revealed; and b. a second timing component for indicating a second time period different from the cumulative time period and comprising a time that the timing device has been exposed to a defined temperature during the cumulative time period, the second timing component comprising; i. a second anode layer; ii. a second cathode layer; iii. a second base layer; iv. a second electrolyte attached to the second base layer; and v. a second activator to activate the second timing device, wherein upon activation of the second timing component, the anode layer depletes in a direction away from the cathode layer and a second electronically readable information is revealed. - View Dependent Claims (22, 23)
