  • Patent number: 6161877
    Abstract: A conduit interlock assembly for being clamped to portions of a pair of conduits which portions are adjacent an end-to-end interconnection between the two conduits and which conduit interlock assembly is for surrounding a conduit fastener or fasteners fastening the conduits together in the end-to-end connection. The conduit interlock assembly includes a normally open switch for being closed upon the conduit interlock assembly being clamped to the conduits to provide an indication that the conduits are in the end-to-end interconnection and which switch is opened upon the conduit interlock assembly being unclamped from the conduits to provide an indication that the conduits possibly are not in the end-to-end interconnection.

  • Patent number: 6131149
    Abstract: A novel apparatus and method is disclosed to assure validity of data accessed from synchronous memory during a "read" operation, wherein the synchronous memory is operating synchronously at a high frequency system clock. The invention comprises a programmable delay module which generates a skewed clock signal which is used to clock in data read from the synchronous memory. The programmable delay module generates the skewed clock signal by adding programmable time delays to the system clock signal. The inserted delay increases the data valid window time available for the "read" operation and allows sufficient setup and hold time for valid data to be read by a memory controller.

  • Patent number: 6011773
    Abstract: Devices, systems, and methods prevent rigid recording media for video and other data from rattling within a cartridge when that cartridge is removed from a disk drive. To decrease rattling (and the resulting damage to the disk), a hub of the disk is urged against an inner surface of the cartridge housing. A door translates laterally to provide access to the disk within the cartridge. A feature is defined by an inner surface of the cartridge housing, and one or more resilient arms extend from the door assembly so as to engage the feature when the door moves towards a closed position. The feature deflects the arm axially against the disk, so that the arm can act as both an actuation mechanism and a biasing spring.

  • Patent number: 5939831
    Abstract: The present invention provides systems, methods and apparatus for high temperature (at least about 500-800.degree. C.) processing of semiconductor wafers. The systems, methods and apparatus of the present invention allow multiple process steps to be performed in situ in the same chamber to reduce total processing time and to ensure high quality processing for high aspect ratio devices. Performing multiple process steps in the same chamber also increases the control of the process parameters and reduces device damage. In particular, the present invention can provide high temperature deposition, heating and efficient cleaning for forming dielectric films having thickness uniformity, good gap fill capability, high density, low moisture, and other desired characteristics.

  • Patent number: 5621859
    Abstract: The invention provides a method of large vocabulary speech recognition that employs a single tree-structured phonetic hidden Markov model (HMM) at each frame of a time-synchronous process. A grammar probability is utilized upon recognition of each phoneme of a word, before recognition of the entire word is complete. Thus, grammar probabilities are exploited as early as possible during recognition of a word. At each frame of the recognition process, a grammar probability is determined for the transition from the most likely preceding grammar state to a set of words that share at least one common phoneme. The grammar probability is combined with accumulating phonetic evidence to provide a measure of the likelihood that a state in the HMM will lead to the word most likely to have been spoken. In a preferred embodiment, phonetic context information is exploited, even before the complete context of a phoneme is known.

  • Patent number: 4889892
    Abstract: The compositions contain, as vinyl chloride polymers, copolymers of vinyl chloride and of alkyl acrylates in which the alkyl radicals, consisting of linear or branched chains, contain from 1 to 10 carbon atoms and have an initial Shore A hardness not exceeding 85. They are suitable for the production of very diverse flexible articles, especially in the medical field (pouches for blood and for physiological fluids), the motor vehicle field (various profiles and seals) and the building industry (sealing sheets).
