Planar vibratory gyroscopes |
摘要 |
<p>Planar vibratory gyroscope structures are provided which are inherently symmetric, which facilitate the use of simple monolithic fabrication processes and which enable the use of sensitive control and sense systems. A planar vibratory member (22) of these structures has a hollow frame (26), a plate (28) that has a plate perimeter (30) and is positioned within the frame (26) and a plurality of elongate beams (32) which couple the plate (28) to the frame (26) wherein each of the beams (32) is proximate to and substantially parallel to a respective portion (30A) of the plate perimeter (30). The exterior rim (34) of the planar member (22) can be supported by a substrate (24) which provides room for easy access to the plate (22) with mode control and sense systems (40, 42). <IMAGE></p> |
