Abstract

See full text

Sensors and systems for detecting predetermined environmental conditions or changes may include a device capable of storing, representing, or providing information, and a shield. The shield may be disposed proximate the device. The shield may have a first condition and a second condition. In the first condition the shield is configured to prevent access to information stored in or on, represented by or provided by the device. In the second condition the shield is configured to permit access to information stored in or on, represented by or provided by the device. The shield may be configured to transition from the first condition to the second condition when the shield is exposed to the predetermined environmental condition.
