1. A method for activating a device, comprising:
- listening for an activate command at a device;
receiving the activate command, the activate command including an activate code;
activating the device in a first high power mode if the activate code matches one of a plurality of values stored in the device; and
activating the device in a second high power mode if the activate code matches another of the plurality of values stored in the device,wherein activating the device includes the steps in the device of;
listening, in a low power mode, for the activate command,receiving a signal that may or may not be the activate command,determining based on an interrupt signal whether the signal is the activate command, andpowering up the device in the corresponding high power mode if the activate code is determined to match one of the plurality of prestored values.

Abstract
Systems and methods for activating devices such as RFID tags includes activating a device if an activate command matches a value stored on the device. The activate command can also define which mode of operation or state the device will initiation in, and whether an additional function or functions is to be performed upon activation. Activate commands can also be dynamically assigned to devices in order to increase overall efficiency.

18. A method for activating a device, comprising:
-
listening while operating in a low power state, for an activate command at a device;
receiving the activate command, the activate command including an activate code;activating the device in a first high power mode if the activate code matches one of a plurality of values stored in the device wherein at least one functional component related to the first mode of the device is selectively coupled to a power source during the activating the device in the first mode; and activating the device in a second high power mode if the activate code matches another of the plurality of values stored in the device, wherein at least one functional component related to the second mode of the device is selectively coupled to a power source during the activating the device in the second mode, wherein the first and second modes relate to how the device functions in a specified regulatory environment, wherein a radio frequency input filter of the device is adjusted to improve its filtering for one specified regulatory environment when in the first mode, wherein the radio frequency input filter of the device is adjusted to improve its filtering for another specified regulatory environment when in the second mode.
