Abstract: A backup control system comprises a control package, a file package including a battery monitor and a flip-flop circuit, and a back board having a return wire which provides connec-tion/disconnection of the monitor terminal of the monitor.  The monitor checks a voltage of the monitor terminal at all times and outputs a reset signal to the flip-flop circuit when the voltage of the monitor terminal becomes lower than a reference voltage.          The return wire connects the monitor terminal to the power line when the file package is connected to the connection board, and disconnects the monitor terminal from the power line when the file package is removed from the connection board.  The flip-flop circuit stores one of a set state and a reset state, and changes in state from the set state to the reset state when the reset signal is received from the monitor.

Abstract: A system and method for more efficiently comparing an unverified string to a lexicon, which filters the lexicon through multiple steps to reduce the number of entries to be directly compared with the unverified string. The method begins by preparing the lexicon with an n-gram encoding, partitioning and hashing process, which can be accomplished in advance of any processing of unverified strings. The unknown is compared first by partitioning and hashing it in the same way to reduce the lexicon in a computationally inexpensive manner. This is followed by an encoded vector comparison step, and finally by a direct string comparison step, which is the most computationally expensive. The reduction of the lexicon is accomplished without arbitrarily eliminating any large portions of the lexicon that might contain relevant candidates. At the same time, the method avoids the need to compare the unverified string directly or indirectly with all the entries in the lexicon. The final candidate list includes only highly possible and ranked candidates for the unverified string, and the size of the final list is adjustable.
