    • The subject invention relates to a system for identifying, for writing data into and reading data out of electronic tags which may be attached to moving and moveable objects. An interrogator sends an RF signal to a remote tag, the signal including data intended to be received and stored in the tag. The tag backscatter-modulates the received signal with data temporarily and permanently stored in the tag, including data indicating the identity of the object to which the tag is attached. The interrogator has the capability of (1) recognizing the identity of the tagged object from the returned backscatter-modulates signal and (2) transmitting data to the tag only if it has data to be transmitted to that particular tagged object. This permits data to be selectively transmitted to a tag and received and stored by that tag only after the tag has been identified as a correct one to receive that data. The tag, in addition, may have the capability of increasing its sensitivity to the receipt of transmitted data after receiving a signal from the interrogator of sufficient strength to be capable of transmitting data to that tag.
    • 本发明涉及一种用于识别用于将数据写入并从其中读取数据的系统,电子标签可附接到移动和可移动的对象。 询问器将RF信号发送到远程标签,该信号包括要被接收并存储在标签中的数据。 标签利用数据临时和永久地存储在标签中的数据进行反向散射调制接收的信号,包括指示标签附加到的对象的身份的数据。 询问器具有以下能力:(1)从所返回的后向散射调制信号中识别标记对象的身份,以及(2)只有当数据要发送到该特定标记对象的数据时才传送到标签。 这允许选择性地将数据传输到标签,并且仅在标签被识别为正确的标签才能接收和存储该标签以便接收该数据。 此外,标签可以具有在从询问器接收到具有足够强度的信号以能够向该标签发送数据之后增加对接收发送数据的灵敏度的能力。
