Filed: 1994-10-12
Granted: 1998-12-15
Abstract: The invention relates to a method and apparatus for speech recognition, the speech to be recognized including one or more words. Recognition is based onan analysis of a first and a second utterance. In accordance with the invention, the first utterance is compared to one or more models of speech to determine a similarity metric for each such comparison. The model of speech which most closely matches the first utterance is determined based on the one or more similarity metrics. The similarity metric corresponding to the most closely matching model of speech is analyzed to determine whether the similarity metric satisfies a first recognition criterion. The second utterance is compared to one or more models of speech associated with the most closely matching model (which may include the most closely matching model) to determine a second utterance similarity metric for each such comparison. The one or more second utterance similarity metrics are analyzed to determine whether the one or more metrics satisfies a second recognition criteria. The second utterance is recognized has the phrase corresponding to the most closely matching model of speech when the first and second recognition criteria are satisfied. The present invention has application to many problems in speech recognition including isolated word recognition and command spotting. An illustrative embodiment of the invention in the context of a cellular telephone is provided. Other embodiments are also discussed.

Abstract: A dispensing system and method for moving a confectionery mixture having a predetermined ratio of air to fluid to a freezing cylinder comprises a multiple portion tube containing the confectionery mixture, an air meter for controlling the ratio of air to fluid in the mixture, and a peristaltic pump for pumping the confectionery mixture through the tube. The peristaltic pump is positioned between a reservoir and the freezing cylinder and the tube is routed through the pump to form a generally U-shaped trough. When the pump is idle, some of the confectionery mixture settles in the generally U-shaped tube to form a liquid seal which prevents air from back flowing from a pressure side to a suction side of the pump. Accordingly, the consistency of the confectionery product is maintained when the pump is idle. The peristaltic pump also includes a proximity switch which prevents the pump from operating until all of its movable parts are properly secured.

Abstract: An exhaust purification apparatus comprising an expansion pipe and a thin ca talyst in the exhaust system of an internal combustion engine. Two openings for discharging an exhaust gas are formed in the peripheral wall of the expansion pipe at the end thereof on the upstream side in its longitudin al direction, and center portions of gas- permeable thin catalyst in their transverse direction are disposed separatel y round the expansion pipe in such a manner as to oppose the openings for the exhaust gas. Both side portions of the th in catalyst are curved towards the expansion pipe and are welded integrally to the outer peripheral surface. The outer p eriphery of the thin catalyst is sealed by a thin sealing plate as a seal member, and an opening is formed in the sealing plate on the opposite side to the openings for the exhaust gas of the expansion pipe. A communication pipe whose upper end is fitted into the opening of the thin sealing plate penetrates through an opening of a muffler casing which i s disposed substantially adjacent to, and in parallel with, the expansion pipe. The lower end of the communication pi pe has a U-shaped section which is open towards the downstream side of the muffler casing. According to this constr uction, the exhaust gas can come into contact with the thin catalyst without beingcooled by the expansion pipe or affected by the catalytic reaction heat. Therefore, a purification ratio and scavenging efficiency can be improved, a nd the size of the purification apparatus can be reduced.
