    • An RFID tag includes a transceiver for communicating with a tag reader; memory for storing a deactivation string, an encrypted deactivation string created externally to the tag by encrypting the deactivation string, and a trial string created externally to the tag by decrypting the encrypted deactivation; and logic for comparing the deactivation string and the trial string to determine whether they are the same, and, if they are the same, configuring the tag to permit deactivation. A method executed by the RFID tag includes comparing the trial string with the deactivation string to determine whether they are the same, and if they are the same, configuring the tag to permit deactivation. The trial string may be created externally to the tag by decrypting, using a first key, an encrypted deactivation string that is created externally to the tag by encrypting the deactivation string using a second key.
    • RFID标签包括用于与标签读取器通信的收发器; 用于存储去激活字符串的存储器,通过加密去激活字符串向标签外部创建的加密去激活字符串;以及通过解密加密的失活而在标签外部创建的试用字符串; 以及用于比较去激活字符串和试用字符串以确定它们是否相同的逻辑,并且如果它们相同,则配置标签以允许停用。 由RFID标签执行的方法包括将试用字符串与去激活字符串进行比较,以确定它们是否相同,并且如果它们相同,则配置标签以允许去激活。 可以通过使用第一密钥解密通过使用第二密钥加密去激活字符串而在标签外部创建的加密去激活字符串来对标签外部创建试用字符串。

    • Methods and apparatus for controlling flare in roll-forming processes are disclosed. An example system includes a component position detector configured to detect a component. The example system also includes a comparator configured to compare a flare tolerance value and a flare measurement value of the component and a storage interface configured to retrieve a roller position value from a memory based on the comparison. In addition, the example system includes a flange roller adjuster communicatively coupled to the storage interface and the component position detector and configured to obtain the roller position value from the storage interface and change a position of a roller based on the roller position value to condition the component.
