  • HIGH VOLTAGE CHARGE PUMP REGULATION SYSTEM WITH FINE STEP ADJUSTMENT
    Publication number: 20130076432
    Abstract: A regulator system for a charge pump system divides the binary decoding into two branches. One controls a set of parallel connected resistors for fine output voltage steps. The other branch controls a serial resistor to provide the large step size. For example, a 9-bit digital input signal is split into 2 least significant for the fine adjustment and the other 7 bits for the larger adjustments. In the example of a 50 mV step size, in one current path 2 bits of the binary input then control two parallel resistors for 50 mV and 100 mV step size, and in the other current path 7 bits are used for one-hot-decode control serial resistors to provide a 200 mV step size. A unity gain operational amplifier and a high voltage device are added in between the two branches to decouple the parasitic capacitance of large parallel resistors from the other elements.

  • CALENDAR MECHANISM
    Publication number: 20130051183
    Abstract: Calendar mechanism for a timepiece, includes: at least one mobile (22; 23) for driving an indicator, a wheel (1) which, during normal operation of the timepiece, is driven in a first direction (S1), a lever (16) for actuating the mobile (22; 23), and first and second cams (2, 3) driven by the wheel (1) and controlling the movements of the actuating lever (16), these first and second cams (2, 3) being arranged so that their relative angular position differs depending on the direction of rotation of the wheel (1) so that the movements of the actuating lever (16) cause the mobile (22; 23) to advance periodically during normal operation of the timepiece and do not permit the mobile to advance during backwards time setting of the timepiece causing the wheel to rotate in a second direction (S2) opposite to the first direction (S1).

  • Methods for forming small-scale capacitor structures
    Patent number: 8384192
    Abstract: The present disclosure provides small scale capacitors (e.g., DRAM capacitors) and methods of forming such capacitors. One exemplary implementation provides a method of fabricating a capacitor that includes sequentially forming a first electrode, a dielectric layer, and a second electrode. At least one of the electrodes may be formed by a) reacting two precursors to deposit a first conductive layer at a first deposition rate, and b) depositing a second conductive layer at a second, lower deposition rate by depositing a precursor layer of one precursor at least one monolayer thick and exposing that precursor layer to another precursor to form a nanolayer reaction product. The second conductive layer may be in contact with the dielectric layer and have a thickness of no greater than about 50 ?.

  • LIGHT GUIDE ARRAY FOR AN IMAGE SENSOR
    Publication number: 20130034927
    Abstract: An image sensor pixel that includes a photoelectric conversion unit supported by a substrate and an insulator adjacent to the substrate. The pixel includes a cascaded light guide that is located within an opening of the insulator and extends above the insulator such that a portion of the cascaded light guide has an air interface. The air interface improves the internal reflection of the cascaded light guide. The cascaded light guide may include a self-aligned color filter having air-gaps between adjacent color filters. These characteristics of the light guide eliminate the need for a microlens. Additionally, an anti-reflection stack is interposed between the substrate and the light guide to reduce backward reflection from the image sensor. Two pixels of having different color filters may have a difference in the thickness of an anti-reflection film within the anti-reflection stack.

    Publication number: 20130012942
    Abstract: A segmented bone fixation device is provided with an elongate body having a longitudinal axis and having a first state in which at least a portion of the body is flexible and a second state in which the body is generally rigid. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a segmented fixation device into an intramedullary space of the bone to place at least a portion of the fixation device in a flexible state on one side of the fracture, providing rigidity across the fracture, and operating an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations allow a segmented device body to change shape as it moves from a flexible state to a rigid state.
