    • A system and method for controlling remote devices utilizing a radio frequency identification (RFID) tag device (30) having a control circuit (33) adapted to render the tag device, and associated objects, permanently inoperable in response to radio-frequency control signals. The control circuit (33) is configured to receive the control signals (37) that can include an enable signal, and in response thereto enable an associated object, such as a weapon; and in response to a disable signal, to disable the tag (30) itself, or, if desired, to disable the associated weapon or both the device and the weapon. Permanent disabling of the tag (30) can be accomplished by several methods, including, but not limited to, fusing a fusable link, breaking an electrically conductive path, permanently altering the modulation or backscattering characteristics of the antenna circuit (36), and permanently erasing an associated memory (38). In this manner, tags in the possession of unauthorized employees can be remotely disabled, and weapons lost a battlefield can be easily tracked and enabled or disabled automatically or at will.

    • A radio frequency identification system having a radio frequency transceiver for generating a continuous wave RF interrogation signal that impinges upon a RF identification tag. An oscillation circuit in the RF identification tag modulates the interrogation signal with a subcarrier of a predetermined frequency and modulates the frequency-modulated signal back to the transmitting interrogator. The interrogator recovers and analyzes the subcarrier signal and determines its frequency. According to one aspect of the invention, the interrogator generates an output indicative of the frequency of the subcarrier frequency, thereby identifying the responding RFID tag as one of a "class" of RFID tags configured to respond with a subcarrier signal of a predetermined frequency.
    • 一种具有射频收发器的射频识别系统,用于产生冲击RF识别标签的连续波RF询问信号。 RF识别标签中的振荡电路用预定频率的子载波调制询问信号,并将调频信号调制回发送询问器。 询问器恢复并分析子载波信号并确定其频率。 根据本发明的一个方面,询问器产生指示子载波频率的频率的输出,从而将响应的RFID标签识别为被配置为利用预定频率的子载波信号进行响应的RFID标签之一。
