A switchpower conditioning module may be added to a hybrid vehicle to selectively supply power from an AC power bus to a load, providing on-vehicle standby power generating capability with a minimum of added hardware andor when the vehicle is stationary. The time of arrival of the last step in the mixing processing for the number of channels, corresponding to the designated mode, is detected to output an accumulation result obtained at the last step, and new accumulation is started with a digital audio signal inputted at a step following the last step. The method for rinsing employs a solid neutral or neutralizing rinse composition for rinsing the medical cart, cage, instrument, device, or equipment. Accelerated movement of the holes from the base layer through the emitter layer reduces emitter delay time and thereby, increases the cut-off frequency and the maximum oscillation frequency of the resultant HBT. It is detected if a valid delivery of the requested service has been performed, if so, the delivered amount of said requested service is accumulated; and available amount is updated in dependence of the delivered amount. A new data entry is then stored into an entry of the data structure represented by the index value.
