  • Patent number: 5992014
    Abstract: A method of using diesel engine injection pump timing tool having two components, a first tubular cylindrical component (1) being internally threaded on one half for attachment to the fuel injection pump and externally threaded on the other half with a square drive wrench hole (8) in the end. A second cylindrical component (2) larger than the first component which contains internal threads on one end for rotatable attachment to the threads (4) of the first component (1). The second component (2) also contains a socket wrench attachment on the outer distal end for rotating the tool onto the first component (1) and also for turning the fuel injection pump to the proper position. The second component (2) may have a knurled grip (5) on a portion of the extended surface for better hand gripping purposes.

  • Patent number: 5832429
    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.

  • Patent number: 5708704
    Abstract: The present invention provides a system for a voice prompt talkover capability. The system and method include a speech recognizer (36), an echo canceler (24), a delay finder (27) and a utterance extraction mechanism (30). The delay finder (27) determines the propagation delay between outgoing signal and the incoming signal and stores the signal in a delay buffer (23) in accordance with the delay and the filter length of the echo canceler. The echo canceler (24), using the incoming signals, the delay buffer and the delay enhance the incoming signal by removing the echo. The utterance extractor (30) determines the start of an utterance based on energy in the vectors of the LPC buffer (28). Upon the detection of an utterance the utterance extractor (30) initiates the start of recognition and terminates operation of the echo canceler (24) and the prompt play out (14). A recognition result is returned from the speech recognition processor (36) to the application (12).
