  1. 1st MEMS Commercial Tuning Fork Gyroscope Draper Labs Area1mm2 ! M. Weinberg, J. Bernstein, S. Cho, A. T. King, A. Kourepenis, P. Ward, and J. Sohn, “A micromachined comb-drive tuning fork gyroscope for commercial applications,” in Proc. Sensor Expo, Cleveland, OH, 1994, pp. 187–193.

  2. A Quartz Tuning Fork Gyroscope

  3. Economy of Scale to Lower Cost “..high volume occurred once unit prices achieved $3 target prices.” A Critical Review of MEMS Gyroscopes Technology and Commercialization Status Steven Nasiri, 408-988-7339 x108, snasiri@invensense.com 3150A Coronado Drive, Santa Clara, California 95054

  4. Applications • Automotive: vehicle stability control, rollover detection, navigation, load leveling/suspension control, event recording, collision avoidance • Consumer: computer input devices, handheld computing devices, game controllers, virtual reality gear, sports equipment, camcorders, robots • Industrial: navigation of autonomous (robotic) guided vehicles, motion control of hydraulic equipment or robots, platform stabilization of heavy machinery,humantransporters, yaw rate control of wind-power plants • Aerospace/military: platform stabilization of avionics, stabilization of pointing systems for antennas, unmanned air vehicles, or land vehicles, inertial measurement units for inertial navigation A Critical Review of MEMS Gyroscopes Technology and Commercialization Status Steven Nasiri, 408-988-7339 x108, snasiri@invensense.com 3150A Coronado Drive, Santa Clara, California 95054
