Abstract: A computer system for speech recognition is described which contains a word table and a triphone table in the memory. If during the recognition of an unknown spoken text the computer system encounters a new word which is not contained in the word table, the fenemic base form of this new word can be synthetically generated with the aid of the triphone table. For this purpose, the new word is separated into triphones and the fenemic sequences belonging to the individual triphones are read out of the triphone table. The fenemic sequences are then joined together in accordance with the phonetic base form of the new word which results in the fenemic base form of the new word. <IMAGE>

Abstract: Disclosed is a cardiac defibrillator for providing a cardiac defibrillation pulse to a patient. The defibrillator comprises a switch contact (14) mounted on a movable switch (10) that moves between a charge position and a discharge position. In the charge position, the switch contact (14) is coupled to a high-voltage battery (22) in order to provide a charge to an energy storage capacitor (30). When the movable switch (10) is released from the charge position, the switch contact (14) engages an electrode contact (32) and a defibrillation pulse flows into a patient (40). The duration of the cardiac defibrillation pulse can be varied by changing the length of time that the switch contact (14) remains engaged with electrode contact (32). Also disposed within the switch contact path is a discharge contact (42), which is connected to a discharge resistor (48). When the movable switch (10) is in a discharge position, the switch contact (14) is engaged with the discharge contact (42) thereby allowing the discharge resistor (48) to dissipate charge from the energy storage capacitor (30). A spring (16) is connected to the movable switch (10) in order to rotate it between the charge and discharge positions.

Abstract: A metal-to-metal antifuse structure includes a pedestal structure in an underlying insulating layer upon which a lower conductive antifuse electrode is formed. An inter-metal dielectric layer is formed and planarized, having a differential thickness between the on-pedestal and off-pedestal regions. An antifuse cell opening is formed in the inter-metal dielectric over the pedestal region. A suitable antifuse material is deposited in the cell opening and an upper electrode is formed over the antifuse material. Another metal-to-metal antifuse structure includes a conductive lower electrode for an antifuse formed over an underlying insulating layer. An antifuse dielectric material is then formed over the lower electrode and an antifuse cell opening is formed in the antifuse dielectric material. A layer of antifuse material is then formed in the antifuse cell opening and an upper antifuse electrode is formed over the antifuse material. The upper antifuse electrode is then patterned and an etching step is used to remove the unprotected portions of the upper antifuse electrode and the antifuse material. An inter-metal dielectric layer is then formed and planarized and an antifuse cell opening is etched therein down to the upper antifuse electrode. An upper metal interconnect layer is formed over the inter-metal dielectric layer and in contact with the upper antifuse electrode.

Abstract: A fluorinated polydiorganosiloxane elastomer having improved physical properties can be obtained through the use of a method which first reacts a hydroxyl endblocked trifluoropropylmethylsiloxane having a Williams Plasticity Number of greater than 225 with a methylvinyldi(N-alkylacetamido)silane to give a chain extended polymer having pendant vinyl groups only at the location of the chain extension. The polymer is then reinforced with fume silica and compounded into a stock. The cured stock has improved tensile strength and tear strength when compared to similar compositions which do not contain the same type of polymer. The polymer has pendant vinyl groups located along the polymer chain, with the distance between them being relatively large. When too many vinyl pendent groups are present along the chain, the improved results are not obtained.
