A storage container system for mounting a storage box on the exterior of a vehicle has trapezoidal members attached to the vehicle that mate with and hold U-shaped members mounted on the container to be carried. A mismatch of bit packing formats between little endian format and big endian format is determined by detecting the occurrence of ADPCM code words of interest in the decoded voice data stream out of the encoderdecoder. In one aspect of the invention, an inner member is provided that filters fluid as it enters the fluid pathway. In one embodiment of the invention, web is pulled from a web supply by a pull roll station, which engages the web material to feed it at an approximately constant feed rate to a metering roll station. The proximal end is attached to a distal end of the magnetostrictive element. Suitable propellants include pressurized gases, such as nitrous oxide, liquefied hydrocarbons, or mixtures thereof.
