Title: Method and apparatus for discriminative training of acoustic models of a speech recognition system
Inventor: BARNARD ETIENNE
IPC: G10L15/06
Filed: 2000-11-02
Abstract: A method and apparatus are provided for automatically training or modifying one or more models of acoustic units in a speech recognition system. Acoustic models are modified based on information about a particular application with which the speech recognizer is used, including speech segment alignment data for at least one correct alignment and at least one wrong alignment. The correct alignment correctly represents a phrase that the speaker uttered. The wrong alignment represents a phrase that the speech recognition system recognized that is incorrect. The segment alignment data is compared by segment to identify competing segments and those that induced the recognition error. When an erroneous segment is identified, acoustic models of the phoneme in the correct alignment are modified by moving their mean values closer to the segment's acoustic features. Concurrently, acoustic models of the phoneme in the wrong alignment are modified by moving their mean values further from the acoustic features of the segment of the wrong alignement. As a result, the acoustic models will converge to more optimal values based on empirical utterance data representing recognition errors.

Abstract: The invention relates to a packaging material made of a multilayer oriented polyolefin film, which comprises a base layer and at least one first outer layer, whereby the first outer layer is placed in contact with itself or in contact with the opposing surface of the film or in contact with the surface of another film. This first outer layer contains an additive which absorbs light within the wavelength range of a laser such that when the film is locally irradiated by the laser, the area of irradiation experiences an increase in temperature that causes the polyolefin of the first outer layer to soften or melt in the irradiated area and to bond to another layer when cooled.
Patent CA-2396645-A1 (CA)
Inventor: FRITSCH JOSEPH FREDERICK
IPC: G11B5/41

Abstract: A cleaning device (1) for cleaning a video head and drum of a video recorder and/or playback unit comprises a housing (6) within which a carrier arm (28) is pivotally mounted and carries a cleaning brush (29) and is pivotal from a retracted position (28) within the housing (6) to a treating position with the cleaning brush (29) in cleaning engagement with the drum (2) under the action of a torsion spring (33). A retaining rib (48) extending inwardly from a lid (20) of the housing (6) acts on the cleaning brush (29) for retaining the carrier arm (28) and the cleaning brush (29) in the retracted position. An abutment edge (50) on the carrier arm (28) is positioned so that as the housing (6) is being lowered into a cassette receiving area (5) of the video recorder and/or playback unit, the abutment edge (50) is located behind a tape withdrawal roller (3) prior to the retaining rib (48) disengaging the cleaning brush (29). Accordingly, the carrier arm (28) and the cleaning brush (29) are retained in the retracted position by the tape withdrawal roller (3) until the tape withdrawal roller (3) commences to move outwardly of the cassette receiving area (5), thus preventing any danger of the carrier arm and cleaning brush becoming entangled with the tape withdrawal roller (3) or any other tape withdrawal rollers until the tape withdrawal rollers have moved outwardly of the cassette receiving area (5).

Patent CA-2398969-A1 (CA)
Inventor: BETHEA CLYDE
IPC: G02B6/42
Filed: 2002-08-21
Abstract: An apparatus and method that prevents a damaging movement in any plane-between fiber ends (103, 203) within a connector assembly (100), where a damaging movement is a movement of the fiber ends (103, 203) with the connector assembly (100) which may give rise to a damaging thermal event while an optical power source (152) is generating a high-optical-power-density signal that is propagated through the fibers (102, 202). A prevention mechanism integral to the connector assembly (100) precludes damaging movement. The prevention mechanism includes a) a locking mechanism that precludes any damaging movement while engaged and b) an indication generator that upon being engaged or disengaged generates an indication that can be used to control the on/off state of the optical power source (152).

Abstract: L'invention concerne des procédés permettant d'obtenir d'un polymère thermoplastique, qui peut être non-mésogénique, qu'il présente de propriétés mésomorphes. Le procédé comporte les étapes consistant à : (a) chauffer le polymère d'une température initiale inférieure à sa température de transition vitreuse (Tg) à une température supérieure à Tg mais inférieure à sa température de fusion (Tm) ; (b) exposer le polymère à une pression supérieure à environ 2 tonnes/pouce?2¿, se situant de préférence entre environ 2 et 10 tonnes/pouce?2¿, de préférence pendant une minute environ, en maintenant la température supérieure à Tg ; et (c) refroidir le polymère à une température inférieure à Tg en maintenant la pression élevée. Contrairement à des procédés de transition actuels qui sont réversibles, le procédé de l'invention permet d'obtenir un état mésomorphe pouvant être maintenu pendant des années en conditions ambiantes. Dans un mode de réalisation préféré, les plastiques sont des polymères thermoplastiques bio-érodables tels que des polyanhydrides, certains polyesters, des polyamides et des polyaromatiques. Les polymères mésomorphes peuvent être utilisés dans la libération ou la rétention contrôlée de substances encapsulées dans des polymères. Le polymère peut être sous diverses formes, notamment de films, d'enduits de film et de microparticules. Dans une forme de réalisation préférée, les polymères mésomorphes sont utilisés pour encapsuler des agents thérapeutiques, diagnostiques ou prophylactiques utiles dans des applications médicales ou pharmaceutiques.
