    摘要： A multiple degrees of freedom motion system comprising an arrangement of rigid stages, flexure constraint modules, actuators, and sensors. These components of the motion system are arranged and connected in a systematic fashion to provide a high degree of decoupling between the motion axes, suitable placement of ground-mounted actuators to actuate each motion axis, and suitable placement of sensors to allow end-point measurement along each motion axis. This arrangement of rigid stages, flexure constraint modules, actuators and sensors enables large motion range and high motion quality in the motion system, while using standard and commonly available components.

    摘要： Flexure bearing systems and configurations guide translational motion along a single-axis in micro and macro applications such as micro-electro-mechanical system (MEMS) devices including sensors and actuators like electrostatic comb-drive actuators. The flexure bearing systems and configurations described herein provide an improved constraint against movement (i.e., stiffness) of the primary mover in non-motion axes such as a bearing axis.

    摘要： A shaft seal serves to reduce leakage between a rotating shaft and a static shell. The shaft seal includes a plurality of compliant plate members, each having a root and a tip. The compliant plate members are secured to one of the static shell and the rotating shaft at their root in facing relation. The tips of the compliant plate members define a sealing ring between the static shell and the rotating shaft. An axial flow resistance member is disposed within the compliant plate members and serves as a harrier to axial leakage flow between the compliant plate members.
