Abstract: A signal conditioning apparatus includes a timing extractor to received one or more stepper motor drive signal and convert each into a corresponding virtual quadrature trigger signal. A resolution scaler is coupled to an output of the timing extractor to scale the virtual quadrature trigger signals to adjust the transition frequency, thereby adjusting the resolution of an image captured by a camera receiving the trigger signals to be different than the print resolution created by the motor drive signals. A quadrature decoder is coupled to the output of the resolution scaler, wherein the quadrature decoder extracts timing and direction information from the virtual quadrature trigger signals received from the resolution scaler.

Abstract: 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.
