Locating a device in a given state
First Claim
1. A method for locating a device in a given state, comprising:
- locating a device using an RFID tag reader and a first RFID tag associated with the device; and
determining the state of the device using an RFID tag reader and a second RFID tag associated with the device;
wherein the first RFID tag responds to queries from an RFID tag reader independently of the state of the device, and the second RFID tag responds to queries from an RFID tag reader selectively in dependence upon the state of the device.

Abstract
Methods and computer program products for locating devices having a given state by locating a device using an RFID tag associated with the device that responds to queries from an RFID tag reader independently of the state of the device, and determining the state of the device using an RFID tag associated with the device that responds selectively in dependence upon the state of the device. The invention also includes systems for locating devices having a given state. The systems comprise an RFID tag reader for locating a device by reading an RFID tag associated with the device that responds independently of the state of the device, and an RFID tag reader for determining the state of the device by reading an RFID tag associated with the device that responds selectively in dependence upon the state of the device.
