Abstract: A method for data communication, where the data compression and decompression is performed by use of a specific hash table, by which data compression a symbol for each data segment is generated, which symbols are transmitted to the receiver where the symbols are decompressed by use of the specific hash table is modified by the specific hash table being performed as a hash table array, which hash table array generates symbols having at least a hash count and a parity check, in which hash table array the parity check comprises generating of a data string, which data string is compared with a parity stored in the hash table, where if both parities are the same, the data model returns the count in the hash table element for transmission, where a zero count is returned indicating that the data string is not valid in the hash table an no transmission is performed.

Abstract: The present invention relates to a method for data communication, where the data compression and decompression is performed by use of a specific hash table, by which data compression a symbol for each data segment is generated, which symbols are transmitted to the receiver, in which receiver the symbols are decompressed by use of the specific hash table. It is the object of the invention to perform reliably and fast data transmission between communication devices by data compression. A further object of the inventions is to perform a secure communication between computerized devices.

Abstract: Dispenser system for dispensing a liquid product, in which a container containing a bag (20), containing therein the liquid product, can be placed in the dispenser system. The dispenser system (15) includes a gas injection element (9) that can be connected to the bag (20) for homogenising the liquid product in the bag (20). The dispenser system (15) further comprises a control unit (1) that is equipped to activate the gas injection element (9) depending on the product present in the bag (20). The container with bag (20) can have an identification element (21), containing data that are important for the operation of the dispenser system (15).
