Systems, methods, apparatus, and computer readable media are provided for disposable component authentication with respect to a biological fluid processing device instrument. An example instrument authentication system includes a computer facilitating configuration and operation of the biological fluid processing instrument using a disposable component. A first interface is provided by the computer and is used by a service technician to configure the biological fluid processing instrument for a number of disposable components and to provide a service technician with a validation code. A key generator is to accept the validation code from the service technician and generate an authentication key in response to the entered validation code. A second interface is provided by the computer, the second interface prompting the service technician to enter an authentication key, wherein the authentication key authorizes use of a certain number of disposable components for the biological fluid processing instrument.

A method and system for synchronizing two clocks of a first and second device. Successive synchronization messages are sent from the first device to the second device. Each synchronization message has a timestamp. Each message is received at the second device and the period between successive timestamps is determined. The period of the second clock of the second device is also determined. The period between timestamps is compared with the period of the second clock of the second device. The period of said second clock is adjusted based upon the comparison.

An apparatus, method and system are provided for multimedia access network channel management, such as channel management in a hybrid fiber-coaxial cable network, for voice (telephony), video, fax and data transmission. The preferred system embodiment includes a plurality of cable telephony modems (CTMs), for such voice (telephony), video, fax and data transmission, and includes a cable modem termination system (CMTS). For upstream communication from the CTMs to the CMTS, the network provides a plurality of channels, formed by a combination of FDM and TDMA. When a CMTS receives an multimedia network access message having a comparative priority from a CTM, the CMTS determines whether there is a first channel which is available from the plurality of channels, and if so, assigns a first transmission corresponding to the multimedia network access message to the first channel. When there is no available first channel, the CMTS determines whether there is a second transmission on a second channel which is moveable to a third channel, and if so, reassigns the second transmission to the third channel and assigns the first transmission corresponding to the multimedia network access message to the second channel. When there is no available first channel and no second transmission which is moveable, the CMTS determines whether there is a third transmission on an assigned channel having a lower comparative priority than the comparative priority of the multimedia network access message, and when there is a third transmission, the CMTS removes the third transmission from the assigned channel to form a vacated channel, and assigns the transmission corresponding to the multimedia network access message to the vacated channel.

A system and method for compressing and decompressing a binary code image includes preprocessing the image to separately group together the operation codes and the operands that make up the binary code image into a columnar format. The resultant preprocessed data is then compressed using any one of a plurality of compression codes. In turn, the resultant compressed image may be stored in a memory element or transferred using a transmission channel to a different device. The compressed image is then decompressed to reconstruct the binary code image.

A system and method for testing memory systems in accordance with the present invention increases efficiency and reduces initial diagnostic and power up time for microprocessor-based units. The method includes copying a test process sequence into a memory system; updating an address indicative of the segment of the memory system being tested; comparing the address to an end of memory system address; copying the test process sequence to a next block of the memory system, and iterating through the method until the addresses are equal and the end of the memory system is reached.
