    • Systems and methods for reading a RFID-tag signal in the presence of noise and other propagation and circuit impairments using a RFID-tag reader are disclosed. The method includes receiving with a RFID-tag reader multiple copies of an original RFID-tag signal from a RFID tag. The original RFID-tag signal comprises an original bit sequence representative of information stored in the RFID tag. At least some of the received RFID-tag signal copies differ from one another due to noise or other signal impairments. The received multiple copies are processed on a sample-by-sample basis in the RFID-tag reader using digital signal processing techniques to obtain an improved received digitized RFID tag signal that substantially removes the noise and other impairments. This improved signal is used to recover the original bit sequence and thus the information stored in the RFID tag.
    • 公开了使用RFID标签读取器在存在噪声和其他传播和电路损伤的情况下读取RFID标签信号的系统和方法。 该方法包括使用RFID标签读取器从RFID标签接收原始RFID标签信号的多个副本。 原始RFID标签信号包括表示存储在RFID标签中的信息的原始比特序列。 由于噪声或其他信号障碍,至少一些所接收的RFID标签信号拷贝彼此不同。 在RFID标签读取器中,使用数字信号处理技术逐个采样处理所接收的多个拷贝,以获得基本上消除噪声和其他损伤的改进的接收数字化RFID标签信号。 该改进的信号用于恢复原始比特序列,从而恢复存储在RFID标签中的信息。

    • There is provided a system for identifying a connection of two or more components in which one or more RFID transponders are associated with the two or more components. A plug is associated with the first component, such as a fiber optic connector, and a socket is associated with the second component, such as a fiber optic adapter. An RFID transponder is associated with each component and at least one of the RFID transponders is activatable when the plug is received by the socket to enable the activated RFID transponder to communicate with the RFID reader. The antennas and integrated circuit chips that define the RFID transponders are positioned relative to the plug and socket to enable the one or more RFID transponders to activate when the plug is received by the socket. In addition, the RFID transponders may communicate with one another to identify other RFID transponders in order to communicate identities of two or more RFID transponders.
    • 提供了一种用于识别其中一个或多个RFID应答器与两个或更多个组件相关联的两个或更多个组件的连接的系统。 插头与第一组件(例如光纤连接器)相关联,并且插座与第二组件(例如光纤适配器)相关联。 RFID应答器与每个组件相关联,并且当插座被插座接收以使得激活的RFID应答器能够与RFID读取器通信时,RFID应答器中的至少一个可激活。 限定RFID应答器的天线和集成电路芯片相对于插头和插座定位,以使得一个或多个RFID应答器在插座被插座接收时被激活。 此外,RFID应答器可以彼此通信以识别其他RFID应答器,以便传达两个或更多个RFID应答器的身份。
