Abstract
The present invention can provide a monitoring method and system for signaling a predetermined status in an article ( ) having a monitored portion ( ). The monitoring system includes an interrogator ( ) which is located in an operative proximity to the article, and is configured to provide input energy with a predetermined input frequency. A status signaling device ( ) is located at the monitored portion ( ) of the article. The status signaling device includes a sensor ( ) which can indicate a change of state that occurs when the monitored portion ( ) of the article ( ) changes from a first condition to a different, second condition. A passive transponder ( ) is in an operative communication with the sensor ( ). In a particular aspect of the invention, the transponder can be an electronic transponder. The transponder ( ) can be configured to receive the input energy from the interrogator ( ), and can be configured to generate indicator data when the monitored portion ( ) is in the second condition. The transponder ( ) can be configured to communicate an output energy away from the article ( ). The output energy can include at least a portion of the input energy, and the output energy can be configured to carry the indicator data. An output receiver ( ) can be configured to electronically acquire the output energy and indicator data from the transponder ( ). A detector ( ) can be connected to the output receiver ( ), and can react to a threshold value of the indicator data. An annunciator ( ) can be in communication with the detector ( ) and can be configured to announce a presence of the threshold value of the indicator data.
