  • Method of making a micromechanical electric shunt
    Patent number: 4674180
    Abstract: A micromechanical electric shunt is fabricated by micromachining according to recent IC fabrication procedures. A plurality of such shunts is incorporated on a single substrate to form novel process station or post identification or signature encoding apparatus for use on a telecommunications bus or the equivalent. Such identification of signature encoding apparatus may be configured for conventional binary coding. Both frequency and current derivative mode apparatus are disclosed.

    Inventors: Paul M. Zavracky, Richard H. Morrison, Jr.
  • Resonant hollow beam and method
    Patent number: 4614119
    Abstract: A microminiature resonant hollow beam sensor is manufactured by micromachining and microfabrication techniques. Specifically, a sensor is formed by etching troughs in a pair of silicon substrates, joining the substrates face-to-face, and etching away unwanted material to free the resonant hollow beam sensors.
