  • Structured light and time of flight depth capture with a MEMS ribbon linear array spatial light modulator
    Patent number: 8970827
    Abstract: A fast spatial light modulator based on a linear MEMS ribbon array enables a depth capture system to operate in structured light and time-of-flight modes. Time-of-flight depth information may be used to phase unwrap structured light depth information. Combined structured light and time-of-flight systems offer precise depth resolution over a wide range of distances.

  • Low voltage drive for MEMS ribbon array light modulators
    Patent number: 8730557
    Abstract: A series bias voltage increases the sensitivity of a MEMS ribbon to control signal voltages. This effect is obtained because of the nonlinear dependence of ribbon deflection on applied voltage. The resulting low-voltage operation of MEMS ribbons makes them more compatible with high speed electronics.

  • Monolithic IC and MEMS microfabrication process
    Patent number: 8445307
    Abstract: Monolithic IC/MEMS processes are disclosed in which high-stress silicon nitride is used as a mechanical material while amorphous silicon serves as a sacrificial layer. Electronic circuits and micro-electromechanical devices are built on separate areas of a single wafer. The sequence of IC and MEMS process steps is designed to prevent alteration of partially completed circuits and devices by subsequent high process temperatures.
