Abstract
A timing device for indicating a passage of a duration of time is disclosed. The timing device in accordance with the embodiments of the invention has a grid array architecture. The grid array architecture includes an electrode structure with an anode layer, a cathode layer and a thermistor layer. The anode layer and the thermistor layer are electrically coupled through a plurality of cathode line structures. In operation the timing device is actuated through a suitable mechanism to initiate depletion of the anode layer and, thereby, indicate a passage of a duration time. As the anode layer depletes, sequential cathode line structures are exposed and the thermistor layer acts as a variable resistor through a plurality of exposed cathode line structures.

1-20. (canceled)
A device for indicating a passage of time, the device comprising:
- a. a lens;
- b. a base;
- c. a layer positioned between the lens and the base;
- d. an altering mechanism for altering the transparency of the layer and thereby changing the visibility of the base to indicate a passage of time;
- and
- e. an actuator to actuate the device.
A device comprising:
- a. a lens;
- b. a base with a marking thereon;
- c. an altering mechanism for altering the visibility of the marking on the base through the lens and thereby indicating a passage of time, wherein the altering mechanism comprises an optical medium positioned between the lens and the base;
- and
- d. an actuator to actuate the device;
- wherein after the device is actuated, the altering mechanism is sensitive to temperature.
A system for managing food inventories, the system comprising:
- a. a lens, a base, a middle layer, an altering mechanism for altering the transparency of the middle layer, an actuator to actuate the system and an attachment mechanism for attaching the lens, the base, the middle layer, the altering mechanism, and the actuator to an article;
- wherein the transparency of the middle layer is altered to make the base more or less visible through the lens and further, wherein the altering mechanism is inversely sensitive to temperature after actuation.
