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.
Claims20
A timing device for monitoring one or more time periods comprising:
- a. a first reactive chemical cell indicating a first time period;
- b. a second chemical cell independent from the first reactive chemical cell and indicating a second time period, wherein the first reactive chemical cell and the second reactive chemical cell collectively indicate a third total elapsed time period;
- and
- c. an activation mechanism for activating the timing device, wherein the activation mechanism activates the first reactive chemical cell and the second reactive chemical cell at the same time.
A timing system comprising:
- a. a timing scale comprising:
- i. a first reactive chemical cell indicating a first time period;
- ii. a second reactive zone independent from the first reactive chemical cell and for indicating a second time period, wherein the first reactive chemical cell and the second reactive chemical cell collectively indicate a third total elapsed time period;
- b. a mechanism for attaching the system to an additional article;
- and
- c. an activation mechanism for activating the system.
A method of monitoring a period of time:
- a. attaching a timing device to an item;
- and
- b. activating the timing device,
- wherein after activation, a first reactive chemical cell of the timing device indicates a first time period, a second reactive chemical cell of the timing device independent from the first reactive chemical cell indicates a second time period, and wherein the first reactive chemical cell and the second reactive chemical cell collectively indicate a third total elapsed time period.
