  • BISTABLE LINEAR MOTOR
    Publication number: 20110316359
    Abstract: A linear motor or generator includes a cylinder having left, center, and right magnetic portions interposed with left and right magnetic gaps, a left and a right induction coil axially wound around a longitudinal axis of the cylinder, and a flux bridge that magnetically couples the center magnetic portion to the left and right magnetic portions. The motor or generator also includes a flux modulating piston comprising a soft magnetic material for increasing magnetic flux circulation in the left flux path when the piston overlaps with the left magnetic gap and for increasing magnetic flux circulation in the right flux path when the piston overlaps with the right magnetic gap. The left and right magnetic portions of the cylinder may be made of a soft magnetic material that promotes magnetic flux.

  • Method for photonic wavelength error detection
    Publication number: 20020131100
    Abstract: Detecting photonic wavelength errors relies on wavelength shifting a photonic signal comprised of one or more channels. The photonic signal is wavelength shifted by slightly offset shift values to provide a pair of photonic signals with slightly offset wavelengths. The pair of photonics signals is filtered and differentially compared to provide a wavelength error signal.

  • Method and system for syllable parsing
    Patent number: 6188984
    Abstract: A method and system consistent with the present invention parses text into syllables. The text is converted into a sequence of “phonemes,” basic units of pronounceable and audible speech, divided by syllables. The text may be converted into phonemes using a phonetic dictionary, and the phonemes transformed into another phoneme sequence using a set of transformation rules that are ranked for evaluation to determine the syllable barriers.
