Title: Speech recognition system
Inventor: HATTORI HIROAKI
IPC: G10L15/32
Filed: 1997-11-24
Abstract: A speech recognition system is disclosed, in which partial reference patterns capable of being subjects of similarity computation with an input pattern obtained from a speech analyzing unit through analysis of (i.e., feature quantity extraction from) a speech waveform, among reference patterns of words to be recognized which are stored in a reference pattern memory, and cumulative similarities of these patterns, are stored in a temporary pattern memory. A counting unit counts partial reference patterns of higher cumulative similarities than a prevailing threshold stored in a threshold memory. A threshold computing unit computes a threshold of pruning from the correspondence relation between the number of branches and the prevailing threshold. A similarity computing unit computes similarity, with the featuring quantities, of partial reference patterns with higher similarities with reference to the prevailing threshold of pruning. A determining unit determines a word corresponding to one of the partial reference patterns with the highest similarity as a result of recognition.

Patent CA-2225749-A1 (CA)
Inventor: BARNES MIKE
IPC: H02P25/08
Filed: 1996-07-04
Abstract: A switched reluctance electric machine system has an electric machine, a rechargeable DC energy store (7), principal voltage terminals (5, 6) and a controller. Where the machine is an electric motor, it is advantageous to be able to drive the motor from the DC energy store (7) as well as from an AC supply, and to recharge the energy store (7) from the AC supply. The charger which is needed for recharging is formed by a pair of closely-coupled coils (2, 3) forming windings for the machine, and a power converter (4) having a first circuit (9) containing a coil (2) and the principal voltage terminals (5, 6) and a second circuit (14) having a coil (3) and the DC energy store (7), each circuit (9, 14) including an electronic switching arrangement of a switch (12, 12') and a diode (13, 13') arranged in anti-parallel and connected in series with the coil (2, 3) to enable current to flow through each coil in either direction. The controller operates the switches (12, 12') of the converter (4) to provide a required operational mode, without needing manual re-configuration of the system. The charger is therefore formed from existing components, and the system as a whole has a flexibility, enabling the machine to act as a generator as well.
Patent CA-2230735-A1 (CA)
Inventor: COX ROGER W
IPC: H02H3/44
Filed: 1998-03-03
Abstract: A monitor/analyzer for an alternating current (AC) electrical system responds to power line disturbances by generating a trigger signal when a change in voltage with respect to time electrical parameter is greater than a programmed threshold. The monitor/analyser includes a sensor for sensing an AC waveform in the electrical system, an analog-to-digital converter for sampling the AC waveform, and a microcomputer. Firmware of the microcomputer cooperates with the A/D converterand provides a plurality of digital samples of the AC waveform for each of some of its AC cycles. The firmware generates each of plural dV/dt parameters of the AC waveform from a corresponding adjacent pair of the digital samples within one of the waveform's AC cycles. A trigger signal is generated when one of the dV/dt parameters is greater than the programmed threshold. The digital samples of the AC waveform before and after the power line disturbance are captured and output to a display in response to the trigger signal.
