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.
Claims16
A timing device comprising:
- a. a plurality of chemically independent timing zones arranged in a linear fashion, wherein each of the plurality of timing zones indicates a different discrete time period and wherein a combination of the plurality of timing zones collectively viewed together indicates a total elapsed time period;
- and
- b. an activation mechanism for activating the timing device.
A timing system comprising:
- a. a timing scale comprising:
- i. a plurality of chemically independent timing zones arranged in a linear fashion, wherein each of the plurality of timing zones indicates a different discrete time period and wherein a combination of the plurality of timing zones collectively viewed together indicates a 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 comprising:
- a. attaching a timing device to an item;
- and
- b. activating the timing device, wherein after activation, a first zone of a plurality of chemically independent timing zones is activated, wherein each of the plurality of subsequent timing zones are arranged in a linear fashion and indicate a different discrete time period and wherein a combination of the plurality of timing zones collectively viewed together indicates a total elapsed time period.
