IPC: G10L15/06
Filed: 1996-09-11
Abstract: A method and system for enrolling speed dial names includes providing speaker dependent templates and associated telephone numbers and providing a penalized garbage model for unrecognized speech. When a request for a new template is received it is determined if the list of speed dial names is full (Step 201) and is not it is determined if that name is too similar (Step 205) to a name already on the speed dial list. If so, that name is rejected but if not it is determined if the speed dial name is too short (Step 302), and if not too short or if the user wants to enter the short name the system asks the user to repeat the speed dial name and if a match it is entered. If not a match the system will swap the first and second utterance and compare to see if a match.

Abstract: L'invention concerne des cardiomyocytes d'origine porcine et des procédés d'utilisation des cardiomyocytes pour traiter les troubles se caractérisant par une insuffisance cardiaque. Les cardiomyocytes d'origine porcine utilisés sont de préférence des cardiomyocytes d'embryons de porcs. Les cardiomyocytes d'origine porcine peuvent être modifiés en vue de leur transplantation chez un sujet xénogène, tel qu'un être humain. Les cardiomyocytes d'origine porcine peuvent par exemple être modifiés de manière à ce qu'un antigène (par ex. un antigène MEC de classe I) présent à la surface du cardiomyocyte capable de stimuler une réponse immunitaire à l'encontre des cardiomyocytes chez un sujet xénogène, soit modifié (par ex., par contact avec un anticorps anti MHC de classe I, ou un de ses fragments ou de ses dérivés), afin d'inhiber le rejet du cardiomyocyte, au moment où il est introduit dans le sujet. Dans une variante, les cardiomyocytes d'origine porcine sont prélevés sur un porc essentiellement exempt d'organismes ou de substances risquant de transmettre des infections ou des maladies au receveur. Les cardiomyocytes d'origine porcine selon l'invention peuvent être utilisés pour traiter des troubles se caractérisant par une insuffisance cardiaque, par ex. une insuffisance cardiaque congestive, chez un sujet xénogène, par administration de cardiomyocytes.

Title: Dual assist and guard rail for beds
Inventor: CARROLL TIMOTHY J
IPC: A47C21/08
Filed: 1997-12-05
Abstract: An improvement is provided in a bed having a side rail framework, and at least one dual-position rail assembly which is secured on one side of the bed. The improvement includes a rotatable structure upon which the dual-position rail assembly, is mounted in order to enable the dual-position rail assembly to move between two positively-stopped and automatically locked positions. A first of such positively-stopped and automatically locked positions disposes the dual-position rail assembly in an assist, vertically-oriented, position which is perpendicular to the longitudinal axis of the bed. A second of such positively-stopped and automatically locked positions disposes the dual-position rail assembly in a guard, horizontally-oriented, position which is parallel to the longitudinal axis of the bed. The lock structure for assuring such stopped and locked position is one which automatically locks and maintain the assist dual-position rail in a selected one of the positively-stopped and automatically locked first position, or the positively-stopped and automatically locked second position. The dual-position rail assembly is not adopted to be operated by the occupant of the bed, but it can be selectively, otherwise operated to aid a person in getting in or out of bed, or to restrain the person within the bed.
