    摘要: A system and method of authenticating fingerprints. A method of authenticating a fingerprint includes comparing a geometric shape of a scanned fingerprint to a corresponding geometric shape of a stored fingerprint. The geometric shape and the corresponding geometric shape are defined by vertices. The vertices are defined by minutiae points, while the vertices are spaced apart from the minutiae points.

    摘要: In a computer system having a list based natural discourse application adapted for speech recognition. In response to a first user element request, the system searches a list of elements to generate a list of matches which contain elements which satisfy the element request. The system calculates the time required to read out the match list common levels, the time required to read out all matches, and the time required to iteratively query the user as to which matches of one of said common levels to read out. The system then reads out the match list using the method having the lowest calculated time.

    摘要: An automatic gain control method in accordance with the inventive arrangements can include the following steps. Initially, an audio signal can be provided to an audio device which has a range of permissible signal level settings and a signal level controller for establishing a particular signal level setting. In addition, an actual signal level can be measured for the audio signal at an established signal level setting. The measured actual signal level further can be stored in a volume map along with the corresponding established signal level setting. Following the storage of the measured actual signal level in the volume map, a different signal level setting can be established using the signal level controller. Subsequently, the actual signal level can be re-measured and the re-measured actual signal level and corresponding established different signal level setting can be stored in the volume map. Finally, the volume map can be used during an audio processing session to determine a signal level setting for the audio device, wherein the signal level setting corresponds to a desired actual audio signal level. In one aspect of the present invention, the method can also include detecting a hysteresis condition in the volume map.

    摘要: The present invention enables a computer user to select a function represented via a graphical user interface by speaking command related to the function into audio processing circuitry. A voice recognition program interprets the spoken words to determine the function that is desired for execution. The user may use the cursor to identify an element on the graphical user interface display or speak the name of that element. The computer responds to the identification of the element by displaying a menu of the voice commands associated with that element.
