  • Patent number: 5353656
    Abstract: An integrated electrostatically-controlled micromechanical gyroscope with a rotor encompassed within a rotor cavity and electrostatically spun within the cavity. The gyroscope includes a plurality of axial electrostatic rotor actuators above and below the rotor for controlling the axial and tilt position of the rotor within the cavity, and a plurality of radial electrostatic actuators spaced circumferentially around the rotor for controlling the radial and tilt position of the rotor within the cavity. The position of the rotor within the cavity is then resolved to determine the external forces acting on the rotor.

  • Patent number: 5349526
    Abstract: A system and method for converting inoperative sentence elements into operative elements in which a set of grammar rules for substituting sentence elements with different elements is established. A sequential comparison between each grammar rule and the sentence elements is then accomplished to find a match between a grammar rule and one or more contiguous sentence elements. A substitution of the matched element for the different elements from the grammar rule is then accomplished. Such sequential comparison and substitution is continued for the entire series of sentence elements to fully convert the sentence to operative elements.
