Abstract:
The present invention provides a jitter measuring device. The device includes an edge position measuring unit and a jitter calculation unit. The edge position measuring unit receives a serial digital signal and a reference clock and measures edge position for each transition of the serial digital signal according to the reference clock. The jitter calculation unit, which is coupled to the edge detection unit, calculates a first average value of a plurality of edge position values and then determines the jitter of the serial digital signal by calculating an average value of the differences between the first average value and the edge position values.
Abstract:
The invention relates to recording on a medium, and in particular, to laser control during recording data on an optical medium. A laser control method for dynamically adjusting laser power during recording data onto an optical disc comprises: recording normal data onto the optical disc according to an initial laser power; stopping recording when a trigger is generated; reading back the recorded normal data and generating a first recording quality index; recording a test pattern at a test pattern starting point according to a selected laser power; reading back the test pattern and generating a second recording quality index; and determining an adaptive laser power to continually record the normal data according to the first recording quality index and the second recording quality index.
Abstract:
The portable device comprises a control IC imbedded in the portable device and a RF module coupled to the control IC for wireless communication. A display and an input unit are coupled to said control IC. Memory is coupled to the control IC to store data and a projection display module is coupled to said control IC for the data projection. The projection display module includes three liquid crystal panels that perform image displays in red, green, and blue, respectively; light emitting sources employed and positioned in correspondence with the liquid crystal panels, respectively. A dichroic prism is used for each display color combination, wherein the liquid crystal panels and the said light emitting sources are positioned on the light-incidence side of the side surfaces of said dichroic prism. A projection lens is provided on the light emission side of the dichroic prism.
Abstract:
Context-based adapative binary arithmetic coding (CABAC), as used in video standards such as H.264/AVC, with a renormalization of the interval low value plus range that includes partitioning of the bits of the low value to provide output bits plus low value update without bit-level iterations or aggregation of output bits until a full byte can be output.
Abstract:
An electrode structure for use in a transflective liquid crystal display device having a plurality of pixels is disclosed. Each pixel has a reflective region and a transmissive region. The electrode structure at least comprises a first transparent electrode, a reflective electrode and a second transparent electrode. The first transparent electrode is disposed within the transmissive region, while the reflective electrode and the second transparent electrode formed above the reflective electrode are disposed within the reflective region. The area of the second transparent electrode is smaller than the area of the reflective electrode.
Abstract:
A method of performing immersion lithography on a semiconductor wafer is provided. The method includes providing a layer of resist onto a surface of the semiconductor wafer. Next, an edge-bead removal process spins the wafer at a speed greater than 1000 revolutions per minute and dispenses solvent through a nozzle while the wafer is spinning. Then, the resist layer is exposed using an immersion lithography exposure system.
Abstract:
The invention relates to novel nucleic acid and protein sequences from the mung bean Vigna radiata. The nucleic acid sequence, isolated from a bruchid resistant mung bean line, encodes a thionin-like protein with insecticidal properties.
Abstract:
A ceramic control valve includes a valve casing, and a control device including a linking seat and a control lever. The drive block of the control lever has a spherical surface. The receiving hole of the linking seat has a wall having a first portion in contact with the spherical surface of the drive block and a second portion spaced from the spherical surface of the drive block, thereby forming a plurality of gaps. Thus, the gaps located between the drive block and the receiving hole keep a smooth circulation of the air flow, thereby preventing the drive block from being jammed in the receiving hole due to deformation of heat expansion, so that the control lever is operated normally.
Abstract:
A light channeling layer disposed adjacent to the bottom substrate of a transflective display to enhance the back-lighting efficiency. The transflective display has a transmissive area and a reflective area and the transmissive area has a transmission electrode. The light channeling layer comprises a plurality of light conduits, each of which is disposed behind a transmission electrode. The light conduit has a first aperture and a second aperture greater than the first aperture and the first aperture is positioned adjacent to the transmission electrode and a second aperture adjacent to the back substrate, so that light from a back-light source that enters into the light conduct through the second aperture is channeled to the transmission electrode through the first aperture.
Abstract:
The present invention relates to a resizable wireless pointing device with a storable receiver. The body housing comprises at least one inner compartment which is located next to the back of a wheel and used for storage of said wireless receiver. A sliding cover, located on the top of said body housing, which slides back and forth along the longitude axis of the housing and subsequently alters the size of the wireless pointing device. A shutter, which rolls up following the sliding of the cover, closes seamlessly the gap area between the body housing and the cover, and integrates into the surface of the wireless pointing device.
