Claim Text:
1. A microelectromechanical systems (MEMS) device comprising: a first rate sensor; a second rate sensor, said first and second rate sensors being configured to oscillate parallel to a planar surface; drive elements in communication with at least one of said first and second rate sensors for providing a drive signal exhibiting a drive frequency; and a first coupling spring structure interconnecting said first and second rate sensors, said first coupling spring structure enabling oscillation of said first and second rate sensors at said drive frequency in a drive direction dictated by said coupling spring structure, wherein said drive direction for said first rate sensor is a first drive direction associated with a first axis and said drive direction for said second rate sensor is a second drive direction associated with a second axis, said second axis being perpendicular to said first axis; and wherein said first axis is perpendicular to said planar surface, said first drive direction is a rotational drive direction such that said first rate sensor is driven in said rotational drive direction about said first axis; and said second axis is parallel to said planar surface, said second drive direction is a translational drive direction such that said second rate sensor is driven in said translational drive direction parallel to said second axis.
