Portable Terminal Holster for Communicating Terminals

      Described is a hardware implementation to provide a Portable
Terminal Holster (PTH) used for mounting communicating terminals.
The PTH is designed to operate at extreme temperature and vibration
levels.

      The implementation described involves the use of the PTH for
the trucking industry, however, the concept can be base or wall
mounted for use in other applications, such as manufacturing or
distribution industries.

      On-board data processing systems, as designed for specialized
needs of the transportation industry, typically consist of a portable
system unit called a tablet and a mounted docking station called a
PTH.  Fig. 1 shows how the tablet and PTH are mounted onto a truck
dashboard.  The system allows the truck drivers to communicate with
their home base by way of a satellite antenna enabling items, such as
bills of lading, invoices, etc., to be transmitted.  The tablet can
communicate with a host system by using optional communications
facilities, such as satellite type transceivers, business band Radio
Frequency (RF) or cellular transceivers.  The optional circuit cards
to interface these facilities reside in the PTH unit which is
permanently installed in the vehicle.

      Fig. 2 shows the PTH unit which acts as the communications
interface and tablet charging station.  The PTH is mounted to the
vehicle and supports the tablet when the tablet is not being used in
a portable operation.  All features unique to the transportation
industry are housed in the PTH.

      Fig. 3a shows a block diagram of the major components that are
installed in the PTH.  Communications controllers 10 and 11 are
intelligent communications adapter cards which interfa...
