摘要： The transmission couples a cam shaft to an output shaft through a plurality of sets of specialized linkages. Each set of specialized linkages comprises: a displacement waveform generator (DWG) comprising a solid cam rigidly attached to the cam shaft, the outer surface of which produces a periodic displacement that is linearly proportional to rotation angle of the cam shaft over a substantial part of a rotation cycle; an input linear displacement multiplier (ILDM) comprising a link surrounding the cam shaft such that when the cam shaft rotates the link oscillates back and forth with a displacement that is linearly proportional to rotation angle of the cam shaft over a substantial part of a rotation cycle; an output linear displacement multiplier (OLDM) comprising a link pivotally connected to the ILDM through a power coupler, able to slide back and forth, and having a longitudinally extending rack of gear teeth; a disk free to rotate coaxially with the output shaft that has a concentric pinion gear continuously engaging the rack of teeth along the OLDM such that the disk is rotationally oscillated as the OLDM moves back and forth; and one or more calipers that may lock the disk to a flange that is affixed to the transmission's output shaft. Disks are locked to flanges at such times that the output shaft is rotated in a uniform manner. The apparent gear ratio is continuously varied from full forward, to neutral, to reverse by changing the angle between the ILDM and OLDM.

摘要： A speech recognition method and apparatus employ a speech processing circuitry for repetitively deriving from a speech input, at a frame repetition rate, a plurality of acoustic parameters. The acoustic parameters represent the speech input signal for a frame time. A plurality of template matching and cost processing circuitries are connected to a system bus, along with the speech processing circuitry, for determining, or identifying, the speech units in the input speech, by comparing the acoustic parameters with stored template patterns. The apparatus can be expanded by adding more template matching and cost processing circuitry to the bus thereby increasing the speech recognition capacity of the apparatus. Template pattern generation is advantageously aided by using a "joker" word to specify the time boundaries of utterances spoken in isolation, by finding the beginning and ending of an utterance surrounded by silence.

摘要： In a speech recognition system, the beginning of speech versus non-speech (a cough or noise) is distinguished by reverting to a non-speech decision process whenever the liklihood cost of template (vocabulary) patterns, including silence, is worse than a predetermined threshold, established by a Joker Word which represents a non-vocabulary word score and path in the grammar graph.

摘要： Speech recognition calculations are decreased by deactivating (or activating) a word in a grammar graph at the "kernel" level. A word is a sequence of acoustic kernels, each kernel a phoneme spectral vector with min-max duration data on a template.
