Abstract: An image scanner with an image correction function generates a primary image and an auxiliary image of a document. The image scanner includes an image sensing module, a lens module, a scanning platform, a primary light source and an auxiliary light source. The primary light source illuminates the document from a first optical angle and the auxiliary light source illuminates the document from a second optical angle. During alternate illumination by the primary and auxiliary light sources, the scanner respectively generates two images for each document, one of which is a primary image and the other of which is an auxiliary image. The auxiliary image, which includes information concerning damage to the document, is used to correct the primary image, either transmitting the images to a host for further processing, or by processing the images within the scanner.

Abstract: A method and apparatus for continuously locating moveable objects is presented. In one or more embodiments of the present invention, moving objects can be tracked in real-time anywhere in the world, including inside tunnels. A smart mobile unit in the object receives and uses GPS satellite positioning data when available and relies on its built-in autonomous navigation capability when GPS is invalid to continuously determine its current position in map-ready units. The smart mobile unit transmits the position output, using an automatically selected wireless mode of communication, to a central processing station for map generation and display processing. Authorized clients may log onto the central processing station to view the object or multiple objects from anywhere in the world; all that is required is a computer equipment with a display device and a web browser.

Abstract: A treadle-type vehicle body forward drive structure comprised of a base plate, a transmission assembly and a treadle structure installed onto the base plate, a gear assembly enmeshing the transmission assembly to the treadle structure, and a position limiting plate that maintains the position of the drive structure on the base plate, with the extending ends of the transmission assembly follower shaft installed to the wheel hubs of the vehicle body rear wheels. When the treadle rod is tamped slightly downwards, a slant-cut fan gear of the treadle structure causes a slant-cut gear and a straight-cut gear of the gear assembly to synchronously rotate, at which time since the straight-cut gear of the gear assembly is enmeshed with a straight-cut gear of the transmission assembly, they in combination cause the rotation of the follower shaft and, furthermore, the synchronous rotation of the rear wheels. As such, the user is provided riding pleasure and options.

Abstract: Structural and stratigraphic discontinuities are identified in a 3-D volume of seismic data samples, by first selecting a plurality of directions containing a primary direction and at least one secondary direction. Next, one-dimensional, two-trace first discontinuity values are calculated along the primary direction for each seismic data sample in the 3-D data volume. Next, a series of sequentially less restrictive thresholds is defined, such that a significant portion, preferably at least approximately 10%, of the first discontinuity values satisfy the first threshold. This significant portion of first discontinuity values is then stored in an output discontinuity volume at the corresponding sample locations. The following steps are repeated for each remaining data sample until that sample has a value stored at the corresponding sample location in the output discontinuity volume.

Abstract: A method for forming a high-speed device in an integrated circuit is disclosed. The approaches include reduction of gate-size and cutback on device capacitance and resistance. In the present invention, poly-trench etching followed by silicone selective growth and dielectric spacer formation are used to define gate length. A reduced gate size is therefore obtained. As with a dielectric buffer layer positioned below the source and drain regions, the proposed device possesses a largely decreased junction capacitance area. The design of air-gap spacer is to cut down on the overlap capacitance between gate and source/drain. Finally, with the application of raised polysilicon source and drain layers to behave as silicide consumption layer and the utilization of the buffer layer to provide diffusion protection, the silicide layer can be thickly formed to reduce sheet resistance without any increment on the junction leakage current.

Abstract: An uninterruptible power supply (UPS) is electrically coupled to a main board, a hard disk and a power supply of the computer. The UPS comprises a power detection circuit for detecting a power supplying state of the power supply when the computer is halting, a power management circuit for receiving a blackout signal sent from the power detection circuit when a blackout in the power supply is detected, and a power switch circuit is commanded by the power management circuit to switch power of the main board and the hard disk from the power supply to the rechargeable battery for maintaining a normal operation. At the same time, the power management circuit sends a power ready signal to the main board through a power switch on the main board to cause CPU to boot the computer normally and the CPU commands to store temporary data and programs in the memory in the hard disk. Such safely stored data and programs may be retrieved from hard disk by CPU for use when computer is powered on again.

Abstract: An SOI layer has a dielectric layer and a silicon layer formed on the dielectric layer. A shallow trench isolation structure is formed on the silicon layer. The STI structure passes through to the dielectric layer. A thermal diffusion process is performed to drive dopants into a first region of the silicon layer so as to form an N-well or P-well doped region. Next, a thermal diffusion process is performed to drive dopants into a second region of the silicon layer so as to form a P-well or N-well doped region. Finally, an epitaxy layer, having a thickness of about 200 angstroms, is grown on the surface of the silicon layer by way of a molecular-beam epitaxy (MBE) growth process, a liquid-phase epitaxy (LPE) growth process, or a vapor-phase epitaxy (VPE) growth process.

Abstract: Methods of planarizing structures formed on the surfaces of substrates and wafers are disclosed. The methods form a planarizing layer over the surface and the structures, or the locations where the structures are to be formed, such that the top surface of the layer has low areas between the locations of the structures, and such that the low areas lie substantially within a plane which is below the tops of the structures. A polish-stop layer is thee formed over the low areas of the planarizing layer, the polish-stop layer being more resistant to polishing than the planarizing layer and, preferably, the structures. The resulting surface is then polished. The polishing may be accomplished by, for example, standard mechanical polishing, and chemical-mechanical polishing.
