20080251099METHOD FOR REMOVING SMEAR AND MAGNETIC RECORDING/REPRODUCING APPARATUS WITH FUNCTION OF REMOVING SMEAR - Provided is a smear-removing method that can remove smear of a manufactured thin-film magnetic head. The method is performed to a thin-film magnetic head including an MR effect element for reading data having two electrode layers sandwiching an MR effect multilayer as a magneto-sensitive portion therebetween. The method comprises the step of applying a stress voltage less than a breaking voltage of the MR effect element between the two electrode layers to burn off smear. In the method, it is preferable that the stress voltage is applied while an electric resistance or an output voltage of the MR effect element is measured, and the stress voltage is increased until the value of the electric resistance or the output voltage reaches an upper limit specified value specified from a value of an electric resistance or an output voltage in a normal case where smear is not present.10-16-2008

20090251391Method and apparatus for power recycling in a display system - A power recycling method and apparatus for driving capacitive display elements are described. The driving process involves charging and discharging the display elements. More particularly, the method effectively reuses some of the energy during the discharging process. Energy in display elements flows back from the panel to a power supply and other optionally to devices like RAM, MCU directly during the discharging process. Diodes between one or more power supplies and the display elements ensure that the discharge paths are disconnected when the voltage of display elements drops below the voltage of the power supply. A resistor path from the display elements to ground or a power supply lower than the display threshold voltage of the display elements guarantees that elements are turned OFF after the discharge process.10-08-2009

20110221938Optical Black-Level Cancellation for Optical Sensors Using Open-Loop Sample Calibration Amplifier - A Optical Black Pixel (OBP) cancellation circuit corrects offsets in sensors in a CCD/CMOS image sensor when reading dark pixels such at the periphery. A pixel voltage is switched to a sampling capacitor during two phases of the same pixel pulse. Sampling capacitors and feedback capacitors connect to differential inputs of an amplifier. An accumulating capacitor accumulates voltage differences and generates a common-mode voltage that is fed back to another sampling capacitor that stores an amplifier offset. The sampling capacitor and accumulating capacitor and their associated switches form a discrete-time first-order low-pass filter that filters the pixel voltage during the first phase. In the second phase the amplifier acts as a unity-gain amplifier to output an average of the pixel voltage differences generated during an OBP time when blackened or covered pixels are read from the image sensor.09-15-2011
