A method is provided for compressing data from a stream of values using one or many distinct memory addresses as workspace, each memory address containing one or many values. The method works by reading two contiguous data values, of length K and N bits, from the stream, as a memory address reference (MAR) and a symbol, respectively.

A method is provided for compressing data from a source stream of data comprising a string of values using one or more distinct computer memory addresses as workspace, each computer memory address having one or more locations to hold one or more distinct values, respectively. The method works by reading two contiguous data values, of length K and N bits respectively, from a source data stream, as a memory address reference, and a current symbol value, respectively. The current symbol value is written to replace one of the values at the memory address reference if the current symbol value does not match any of the values at the memory address reference, and a MISS code, followed by the current symbol value, are appended to the compressed data stream. Alternatively, if the current symbol value matches any of the values at the memory address reference, then a hit code is added to the compressed data stream, said hit code representing the location, or an attribute associated with the location, where the value was found in the memory address reference. The method is repeated for all symbols read from the source stream. An equivalent, symmetric and reversible decompression or reconstruction method creates an uncompressed data stream equivalent to the original source stream. Advantageously, the workspace employed by the compression method has similar behavior to that of a cache memory used in computer architecture, allowing the compression method to be implemented using content addressable memory, that is associative or intelligent memory for hardware designs or associative arrays for software implementation.

A pneumatic launcher has a plenum chamber section, an intermediate chamber section and a launch tube section connected together in a generally linear arrangement. The plenum chamber section defines a plenum chamber that has a closed end and an open end. The intermediate chamber section has aft and forward rupture disks consecutively arranged to define an intermediate chamber. The plenum chamber is pressurized with a pressurized gas to a design plenum pressure and the intermediate chamber is pressurized with a pressurized gas to pressure that is about one-half the design plenum pressure. The intermediate chamber is then depressurizing to produce a pressure imbalance between the plenum and intermediate chambers that causes said aft and forward rupture disks to rupture. As a result, pressure equilibrium occurs between the plenum chamber and launch tube thereby discharging the fluid and projectile from the interior of the launch tube.
