Abstract: A tape head module assembly method is disclosed. A first and second module holder are placed in an initial alignment with module holder ends facing each other, the module ends each holding a tape head module. A tape wrap angle between the first and second module is set by first performing a fringe alignment and then lifting a rear end of the first and second module holder a prescribed amount. A horizontal adjuster produces a rotation for the first module holder so that gaps between the first and second modules are parallel. An alignment along a longitudinal axis for the second module holder is selected and the second module is translated laterally until the second tape head module held by the second module holder is aligned with the first tape head module held by the first module holder to provide reader-opposite-writer track-to-track registration. Then, the first and second tape head modules are joined together using a joining agent in the gap between the first and second tape head modules.

Abstract: Protocol multiplexer is configured to receive multiple communication links, each link operating with one of a plurality of communication protocols. Protocol handler converts the received data and frames the data according to the communication protocol in use for a particular communication link. Port multiplexer separates the received frames into data frames and control frames. The data frames being multiplexed onto a single data bus and the control frames being multiplexed onto a single control bus to increase performance of the protocol multiplexer.

Abstract: A sign assembly having a frameless-appearing sign face may be removed from and replaced into the assembly. The sign assembly includes a sign face having an outer surface, an inner surface and a peripheral side. The assembly also includes a sign frame having a sign face channel that is adapted to receive a portion of the sign face adjacent to the peripheral side. The sign face channel is defined by an inner frame portion and an outer frame portion. The assembly also includes a mounting component having a face support that is attached to the inner surface of the sign face adjacent to the peripheral side of the sign face, an inner support that is adapted to bear against the inner frame portion of the sign frame, and an outer support that is adapted to bear against the outer frame portion of the sign frame. The invention also includes a method for mounting a sign face on a mounting component and a method for converting a framed assembly into a frameless-appearing assembly.
