    摘要： Electronic writing systems and methods are described. In one aspect, an electronic writing system includes an elongated housing, an inertial sensor, an optical sensor, and a tracking module. The elongated housing has an optical input. The inertial sensor is attached to the housing and is operable to generate data indicative of movement of the housing relative to an inertial reference frame. The optical sensor is attached to the housing and is operable to generate data from light received through the optical input. The tracking module is operable to compute relative displacement data from inertial movement data corresponding to data generated by the inertial sensor. The tracking module also is operable to detect at least one calibrated position from calibration data encoded in optical data generated from light received by the optical sensor.

    摘要： A microelectromechanical system (MEMS) device is disclosed for determining the position of a mover. The MEMS device has a bottom layer connected to a mover layer. The mover layer is connected to a mover by flexures. The mover moves relative to the mover layer and the bottom layer. The flexures urge the mover back to an initial position of mechanical equilibrium. The flexures include coupling blocks to control movement of the mover. The MEMS device determines the location of the mover by determining the capacitance between mover electrodes located on the coupling blocks of the flexures and counter electrodes located on an adjacent layer. The coupling block moves according to a determinable relationship with the mover. As the coupling block moves, the capacitance between the mover electrode and the counter electrode changes. A capacitance detector analyzes the capacitance between the electrodes and determines the position of the mover.

    摘要： The present disclosure includes structures and methods of forming structures for restricting out-of-plane travel. One example of forming such structures includes providing a first wafer 100, 220 comprising a bond layer of a particular thickness 101, 221 on a surface of a substrate material 105, 225, removing the bond layer 101, 221 in a first area 103-1, 103-2, 223 to expose the surface of the substrate material 105, 225, applying a mask to at least a portion of a remaining bond layer 109-1, 109-4, 229-1, 229-3 and a portion of the exposed surface of the substrate material in the first area 109-2, 109-3, 229-2 to form a second area exposed on the surface of the substrate material 105, 225, etching the second area to form a cavity 110, 230 in the substrate material 105, 225 and the bond layer 101, 221, and forming by the etching, in the cavity 110, 230, a structure 113-1, 113-2, 233 for restricting out-of-plane travel, where the structure 113-1, 113-2, 233 has a particular height from a bottom of the cavity 115, 235 determined by the particular thickness of the bond layer 101, 221.

    摘要： A micro-machined actuator for use in, among other things, sensors and data storage devices. The actuator includes a stator wafer and a micro-mover positioned adjacent to the stator wafer. Between the stator wafer and the micro-mover are electrodes that are set to specified voltages and that emanate electric fields that position the micro-mover relative to the stator wafer. Also between stator wafer and the micro-mover are bumpers that prevent the electrodes from coming into contact with each other.
