An image processing system includes an image forming device 100 and an image transmission device 101. The apparatus utilizes a framing mechanism supporting an encapsulator container or workbag adapted to surround and seal off a work-area encompassing a contaminated work-piece. In response to the initiation of a storage operation and according to a second set of selection logic, a network storage device to associate with the storage operation. The gate-source voltages of the output transistors are substantially equal to those of the first and second input transistors. By means of this novel technique, the size of the antenna can be reduced with respect to prior art, or alternatively, given a fixed size the antenna can operate at a lower frequency with respect to a conventional antenna of the same size. After completion of lock operations, the lock requesting node sends a lock release request to the arbitrating node, which, in turn, informs all processing nodes of lock release by transmitting another broadcast message within the system.
