  • Publication number: 20080218630
    Abstract: A content-dependent scan rate converter with adaptive noise reduction that provides a highly integrated, implementation efficient de-interlacer. By identifying and using redundant information from the image (motion values and edge directions), this scan rate converter is able to perform the tasks of film-mode detection, motion-adaptive scan rate conversion, and content-dependent video noise reduction. Adaptive video noise reduction is incorporated in the process where temporal noise reduction is performed on the still parts of the image, thus preserving high detail spatial information, and data-adaptive spatial noise reduction is performed on the moving parts of the image. A low-pass filter is used in flat fields to smooth out Gaussian noise and a direction-dependent median filter is used in the presence of impulsive noise or an edge. Therefore, the selected spatial filter is optimized for the particular pixel that is being processed to maintain crisp edges.

  • Patent number: 7422920
    Abstract: A spatial light modulator is disclosed, along with a method for making such a modulator that comprises an array of micromirror devices. The center-to-center distance and the gap between adjacent micromirror devices are determined corresponding to the light source being used so as to optimize optical efficiency and performance quality. The micromirror device comprises a hinge support formed on a substrate and a hinge that is held by the hinge support. A mirror plate is connected to the hinge via a contact, and the distance between the mirror plate and the hinge is determined according to desired maximum rotation angle of the mirror plate, the optimum gap and pitch between the adjacent micromirrors. In a method of fabricating such spatial light modulator, one sacrificial layer is deposited on a substrate followed by forming the mirror plates, and another sacrificial layer is deposited on the mirror plates followed by forming the hinge supports.

  • Patent number: 7423410
    Abstract: This invention provides a battery protecting circuit where even if the battery voltage falls nearly to zero volts due to overdischarge or the like while an NMOS transistor set in the power feeding path on the side of the positive electrode of the battery is turned ON/OFF, it is still possible to charge the battery by a constant charging current in a stable way. When the voltage of battery B1 has not reached the voltage needed for generating the driving voltage of NMOS transistors Q1, Q2 in drives 111, 112, the boosting operation of drives 111, 112 is stopped, and PMOS transistor Q3 inserted in a power feeding path different from that of said transistors is turned ON by driver 113. In driver 113, by clamping voltage VDD generated in the power feeding path of PMOS transistor Q3 to a voltage lower than it, driving voltage ZVO of PMOS transistor Q3 is generated without performing a boosting operation.

  • Patent number: 7424654
    Abstract: Disclosed herein is an improved method and apparatus for simultaneously performing tests on several devices at the same time. An aspect of one embodiment of the invention is an improved DMA controller that automatically selects certain pin groups, which are connected to a common data bus, to receive test data words from a common data bus. By selecting more than one pin group at the same time, test data (such as a test data word) can be simultaneously loaded onto multiple pin cards at the same time. By loading this data into multiple pin cards at the same time, test data can be “fanned-out” to multiple pin cards and thereby be sent to multiple device sites at the same time. Another aspect of one embodiment of the invention utilizes DMA-based hardware to select which pin groups should received “fanned-out” test data. By utilizing DMA-based hardware to fan-out the test data, the software-based test programs and patterns may be created to manipulate a single device.
