Patent number: 7591179Abstract: A micromechanical motion sensor is capable of detecting a deflection imparted to an oscillatably mounted bar spring element excited to a permanent periodic oscillation by an electrostatic oscillating drive to which a periodic drive voltage is applied. To compensate non-linearities of the resonance frequency response of the bar spring element, a sum of a normal drive voltage signal and a compensation drive signal may be applied to a comb drive. In an alternative embodiment, separate compensation comb drive units may be additionally provided to the comb drive units used for the oscillation drive and a compensation voltage signal may be applied to them to compensate for the non-linearity.Type: GrantFiled: March 24, 2004Date of Patent: September 22, 2009Assignee: Robert Bosch GmbHInventors: Dietmar Krieg, Udo-Martin Gomez, Reinhard Neul

Patent number: 7523663Abstract: A micromechanical rotation rate sensor has a seismic mass and driving devices which cause a driving vibration of the seismic mass in a first direction x. The rotation rate sensor has measuring devices which measure a deflection of the seismic mass in a second direction y, and generate a deflection signal.
