  • Patent number: 7003456
    Abstract: A computer-based method of routing a message to a system includes receiving a message, and processing the message using large-vocabulary continuous speech recognition to generate a string of text corresponding to the message. The method includes generating a confidence estimate of the string of text corresponding to the message and comparing the confidence estimate to a predetermined threshold. If the confidence estimate satisfies the predetermined threshold, the string of text is forwarded to the system. If the confidence estimate does not satisfy the predetermined threshold, the information relating to the message is forwarded to a transcriptionist. The message may include one or more utterances. Each utterance in the message may be separately or jointly processed. In this way, a confidence estimate may be generated and evaluated for each utterance or for the whole message. Information relating to each utterance may be separately or jointly forwarded based on the results of the generation and evaluation.

  • Patent number: 6994108
    Abstract: A check valve for a fuel pump of a vehicle includes a valve housing adapted to be disposed in an outlet member of the fuel pump and a valve seat formed on the valve housing. The check valve also includes a valve member disposed in the valve housing and having a closed position to engage the valve seat to prevent fuel from flowing through the outlet member and an open position to allow fuel to flow through the outlet member. The valve housing has a vortex abating geometry located near the valve seat to add turbulence to fluid flow past the valve seat when the valve member is in the open position.

  • Patent number: 6912498
    Abstract: Correcting incorrect text associated with recognition errors in computer-implemented speech recognition includes receiving a selection of a word from a recognized utterance. The selection indicates a bound of a portion of the recognized utterance to be corrected. A first recognition correction is produced based on a comparison between a first alternative transcript and the recognized utterance. A second recognition correction is produced based on a comparison between a second alternative transcript and the recognized utterance. The duration of the first recognition correction differs from the duration of the second recognition correction. A portion of the recognition result that is replaced with one of the first recognition correction and the second recognition correction. includes at one bound a word indicated by the selection and extends for the duration of the one of the first recognition correction and the second recognition correction with which the portion is replaced.

  • Publication number: 20050108012
    Abstract: A method of constructing a list of alternate transcripts from a recognized transcript includes generating a list of close call records, matching partial sub-histories from the recognized transcript with one of the history pairs stored in each of the records, and substituting the other of the history pairs for the partial sub-history of the recognized transcript. A close call record is generated each time a pair of partial hypotheses attempt to seed a common word. Each close call record includes history information and scoring information associated with a particular pair of partial hypotheses seeding a common word. Alternate transcripts are constructed by substituting close call histories for partial histories of the recognized transcripts, and also by substituting close call histories for partial histories of other alternate transcript.

  • Publication number: 20050022869
    Abstract: A device and method for venting a tank comprising an intermediate shutoff valve as part of a cover that closes a tank opening. The intermediate shutoff valve is placed between an existing valve and a vent port in a liquid storage tank. The shutoff valve is operable to substantially fluidly seal the vent port when the vent valve is displaced greater than a predetermined amount. The intermediate shutoff valve facilitates complete removal of the existing vent valve during an impact wherein a wall of the storage tank impacts the existing valve. Upon impact, the intermediate shutoff valve is operable to close and seal a tank opening created by the displacement and removal of the existing vent valve.

  • Patent number: 6732396
    Abstract: A self-wringing ratchet mop including an elongated handle, a mop head having mop strands supported on the handle, and a wringing mechanism for wringing the mop strands. The wringing mechanism includes a sleeve attached to the mop strands and supported for longitudinal and rotational movement relative to the handle. The handle includes a first ratchet portion formed by teeth and the sleeve includes a second ratchet portion formed by pawl members for engaging the first ratchet portion to permit the sleeve to rotate in a first direction and prevent rotation in a second, opposite direction. The pawl members are supported on a deformable resilient ring wherein deformation of the ring causes the pawl members to disengage from the first ratchet portion and permit rotation of the sleeve in the second direction.
