An RFID tag includes a sensor for determining a transient state or condition of a product to which the tag is associated, and a display. The tag may be passive, semi-passive, or active. In response to receipt at the tag of a read signal that includes a first value associated with the transient state or condition, a comparison is performed. The comparison compares the first value, with a second value generated by the sensor in response to receipt of the read signal. As a result of the comparison, an indication is provided on the display. The information displayed is a function of the comparison. In one embodiment, the display provides different color indications depending on the transient state or condition sensed.

Transient state information display in an RFID tag

A method and system for providing an energy efficient computer management environment via tightly integrated target status and directed work sessions. The illustrative embodiments query, by a lightweight communication means, an availability status of a target computer device using a status thread. The status of the target computer device is recorded in a memory of a central computer according to response from the server thread. Responsive to an absence of a response by the target computer, the illustrative embodiments query, by a heavyweight communication means, the status of the target computer device using the status thread.

In one embodiment, the display provides different color indications depending on the transient state or condition sensed. In an alternative embodiment, the RFID tag display includes an electrical or thermal charge-induced pigment release medium, e.g., an electronic ink, and the tag is used to communicate information about the state of a product to which the tag is associated.
