IPC: B65D21/08
Filed: 1991-07-25
Abstract: ABSTRACT        A  modular   knock-down   packing   container   system, generally of wood,  includes  interchangeable wall panels with corresponding channel guides for guaranteeing the structurally reinforcement and sealing of the interchangeable walls.   The panels are held in place by a combination of the position of the panels within corresponding channel guides and of the use of  central  sphere  rod  connectors,  which  connectors  may  be rapidly and easily loosened for dismantling of the packaging system,   so  that  the  panels  can  be  re-used  in  other configurations.   A  systematic  plurality  of  wall  panels  is provided with incremental dimensioned variations,  so that the size  of  the  containers  can be varied while  preserving  the ability  to  create  large  hollow  interiors  uninterrupted  by perpendicular  floor members.   Expansion  of the  size  of  the containers  is  also  accomplished  without  limiting  interior container storage space by axial connection of the stacking of the panels end over end.  The joints between successive layers of axially connected panels may be reinforced by overlapping strip elements connected in a like manner to the panels are the panels are connected to themselves by the central sphere rod connectors.

Abstract: A wireless communication system containing at least one transmission apparatus and at least one communication terminal. The transmission apparatus transmits a wireless signal representing a bit sequence containing at least a predetermined number of bit errors, to the communication terminal. The communication terminal receives the wireless signal to regenerate the bit sequence. The communication terminal then examines the bit sequence represented by a received wireless signal to determine whether or not the number of bit errors contained in the bit sequence is equal to or greater than a predetermined number. When it is determined that at least the predetermined number of bit errors are contained in the bit sequence represented by a received wireless signal, the operation of the communication terminal is made inactive. Further, the transmission apparatus may transmit a wireless signal representing a bit sequence containing no pattern coinciding with a predetermined frame synchronization pattern, to the communication terminal. The communication terminal receives the wireless signal to regenerate the bit sequence. The communication terminal then examines the bit sequence represented by a received wireless signal to determine whether or not the bit sequence contains the predetermined frame synchronization pattern. When it is determined that the bit sequence does not contain the predetermined frame synchronization pattern, the operation of the communication terminal is made inactive.
