  • System and method for locked code on a radio frequency identification tag
    Patent number: 7316352
    Abstract: A radio frequency identification (RFID) tag system includes a coupler/controller subsystem and a memory. The coupler/controller subsystem wirelessly receives and transmits at least one user signal and at least one master signal. The memory is electrically coupled to the coupler/controller subsystem. The memory includes a user portion for storing information contained in the at least one user signal and a master portion for storing information contained in the at least one master signal, and the master portion of the memory is unalterable by a user.

  • Method and apparatus for automatically activating a one of video data channel and a computer data channel in a tape drive in response to detection of the nature of the data recorded on a magnetic tape loaded in the tape drive
    Patent number: 6239930
    Abstract: The tape drive control unit administers both computer data and video data that is stored on the same type of data storage media. This is accomplished by determining, when a magnetic tape is mounted in the tape drive, the format that is used to store the data on the magnetic tape media. In the case of video data, the data is directly written on to the magnetic tape media, while for computer data, a header is interposed between a leader portion of the magnetic tape on the 3480-type magnetic tape cartridge and the remainder of the magnetic tape contained therein.
