A module enabling individual adaptation by the user to the respective task in the treatment of fluids using housings and connections of existing filtration devices without any modification is described. The building blocks represent a time-sensitive aspect of the treatment regimen, and are selectively assembled by a care provider client computer in substantially any combination, to form a customized treatment regimen. The system includes a transmitter configured such that L symbols of either the beginning or end of the N symbols of the training signal, where L<N, are duplicated at either the end or the beginning of the training signal, respectively. The secondary storage is targeted for more infrequent events with lower level of detail and constructed as an array of count values addressed by a hash function using event type as an input. In some embodiments, the charge trapping structure includes nanodots. An isolation valve arrangement is located within the fluid port assembly and is moveable between an open position for normal operation of the bladder accumulator and a closed position for isolating the bladder accumulator from a hydraulic system, to which is it mounted, wherein, the valve arrangement is fixable in the open position.
