    摘要： An optical image stabilization system for a camera module is disclosed. The stabilization system comprises a voice coil motor (VCM), at least one digital gyroscope for receiving signals from the VCM, and an angular velocity sensor for receiving signals from the digital gyroscope and outputting an angular position error signal. The stabilization system further comprises signal processing logic for receiving the error signal, and comparing the error signal to a reference signal and providing a stabilized image based upon that comparison, wherein the hard-coded logic, digital gyroscope and rate and position sensor resides on the same chip.

    摘要： Optical fibers are inserted and bonded in a two dimensional array of feedthroughs provided by an insert having a top plate, a bottom plate and a sandwiched spacer plate. Top and bottom plate feature funnel shaped hole sections that capture the approaching fiber end during its insertion. The funnel sections terminate in narrow hole sections that tightly hold the inserted fiber ends. Having top and bottom plate spaced apart provides for high angular precision of the bonded fiber ends with minimal fabrication effort of the insert. Optical fibers may be combined in linear arrays and simultaneously inserted significantly reducing assembly efforts. The insert is attached to a fiber housing and hermetically sealed within an external housing, which features a glass plate to provide beam propagation to and from the fiber ends. An optical gel fills the gap between the insert's output face and the glass plate.

    摘要： A method for making an angular velocity sensor having two masses which are laterally disposed in an X-Y plane and indirectly connected to a frame is provided. The two masses are linked together by a linkage such that they necessarily move in opposite directions along Z. Angular velocity of the sensor about the Y axis can be sensed by driving the two masses into Z-directed antiphase oscillation and measuring the angular oscillation amplitude thereby imparted to the frame.

    摘要： An optical switching fabric enables an optical signal entering the device on any one of multiple input ports to be directed to any one of multiple output ports. The present optical switching fabrics include sensing and monitoring devices that permit precise initial calibration and continuous switch connection status monitoring and control. Light entering the switching fabric on an input port is reflected by one of a first set of individually controllable mirrors to one of a second set of individually controllable mirrors and then to a corresponding output port. The switching fabrics include control lasers and position sensing devices which provide output signals corresponding to the orientations of the mirrors. In addition, a subset of the input ports and output ports can be attached to monitor light sources and detectors for recalibration and control. Further, sensors for detecting the intensity of input signals, of signals that have been reflected by a mirror in the first set and by a mirror in the second set, and of signals backscattered from the output ports may be included.

    摘要： A rigid encapsulation package for semiconductor sensors, actuators, and devices is described. In one embodiment, a semiconductor pressure sensor includes a sensor element having a deformable diaphragm for measurement of pressure, and a cap that includes a recess. The cap is attached to the sensor element to form a cavity therebetween. The pressure sensor further includes a leadframe, interconnecting bond wires, a pressure port that is coupled to the sensor element, and a nominally rigid material formed over the sensor element, cap, leadframe, and bond wires. The material may include one or more of the following: epoxy, RTV, resins, and gel. The sensor element may include a built-in stress isolation flexible region. A second pressure port may optionally be attached to the housing for providing differential or gage pressure measurements.
