  • Publication number: 20070072338
    Abstract: The present invention provides a semiconductor device package singulation method. The method comprises printing a photo epoxy layer on the back surface of a substrate of a wafer for marking the scribe lines to be diced. Then etching is performed through the substrate along the marks in the photo epoxy layer. Dicing the panel into individual package with a typical art designing knife, the step not only avoids the roughness on the edge of each die, but also decrease the cost of singulation process.

  • Patent number: 7197076
    Abstract: A method for locating partitions of a video image is provided. The method is used to simplify the process of obtaining the related information of neighboring partitions during the coding and decoding process for the video image. The method starts by mapping the storage units of a matrix to adjacent sub-blocks of a video image. The related information of the partitions is stored in the corresponding storage units. The related information of the neighboring partitions is obtained according to the relative locations of the storage units and the mapping relationship between the storage units and the sub-blocks.

  • Publication number: 20070047108
    Abstract: A suspension apparatus comprises a lens holder, a suspension spring and a supporting base. The supporting base is formed with an opening for accommodating the lens holder. The lens holder is for positioning a lens unit. The suspension spring is manufactured by stamping process to form a long strip with a plurality of suspension springs. The strip is then guided into a mold, and plastic injection molding process is performed in that mold so as to produce the lens holder and supporting base affixed respectively to either end of the suspension spring in one piece. After that, excess material of the strip is cut off. The suspension apparatus as above described is suitable for mass production. In addition, because of the high precision of mold, the inaccuracy of assembly and fabrication is minimized. The volume of the whole apparatus and the cost of production are also vastly decreased.

  • Patent number: 7176907
    Abstract: The invention, an improved device and method for the pointer system of a digitizer tablet, is to repetitiously emit signals sequentially from a specific set of inductive loop when the position pointed by the wireless pointer device is located within a range formed by this specific set of inductive loop induced most intensively during a locally scanning process. After a transient energy storage of the wireless pointer device, corresponding resonant signals are emitted out and are received sequentially by several sets of inductive loop located on the digitizer tablet in the neighborhood of this specific set of inductive loop and, by these signals, the wireless pointer device's coordinate position on the digitizer tablet is calculated out relatively.

  • Publication number: 20070022172
    Abstract: Methods, systems, and products are provided for controlling presentation of instant messages to a recipient in a data processing system. Embodiments include establishing threshold priority criteria, receiving an instant message, determining whether the instant message meets the threshold priority criteria, and presenting to the recipient the instant message if the instant message meets the threshold priority criteria. Determining whether the instant message meets the threshold priority criteria may be carried out by identifying attributes of the instant message and determining whether the attributes of the instant message meet the threshold priority criteria in dependence upon criteria evaluation rules.

  • Publication number: 20060280080
    Abstract: An apparatus and method for automatic power control is disclosed. An optical recording apparatus utilizes a low-speed, peak-hold circuit to obtain and output a maximum of a front photodiode output signal during a predetermined window or plurality of windows of a total duration long enough to allow maximum peak-hold signal to stabilize. After stabilization, the maximum peak-hold signal is sampled and held in a sample and hold circuit. A reset then clears the signal and reinitializes the peak-hold circuit. In accordance with the difference between a reference voltage and the held peak-hold signal, a feedback controller unit outputs the required current level into a driving unit for producing desired recording pulses into a laser diode for recording information pits into an optical disc. A calibration gain may be used when, due to insufficient FPD response speed, the held signal is different than the real optical power output.

  • Patent number: 7149121
    Abstract: A nonvolatile memory array is associated with counting memory that stores data on a number of times a particular threshold state is reached in the associated nonvolatile memory. The aging physical characteristics of the nonvolatile memory can be compensated by adjusting the operating conditions of the nonvolatile memory. The operating conditions vary depending on the data stored in the counting memory.

  • Publication number: 20060245337
    Abstract: A method in which, during an optimal power calibration (OPC) process, an optical disk drive performs a plurality of write tests to an optical disk at a plurality of test powers and measures a corresponding plurality of modulation signal strength values of the optical disk for the plurality of write tests to generate a modulation signal strength versus power curve. The method then determines possible gamma lines corresponding to considered powers, and selects a considered power as a target power of the optical disk drive when a possible gamma line is substantially tangential to the modulation signal strength versus power curve at the considered power. According to the method, powers within a domain of the plurality of test powers are considered until a considered power is selected as the target power for the optical disk.

  • Publication number: 20060197798
    Abstract: A maintenance device for shielding a print-head includes a casing having a first traveling path and a second traveling path transverse to the first traveling path, a sliding member disposed back and forth along the first traveling path; and a shielding unit including a seat movable back and forth along the second traveling path, and having two flanges for engaging a guiding track unit of the sliding member, and a shield fixed on the seat. Movement of the sliding member along the first traveling path in a first direction results in pushing of the seat by the sliding member, thereby moving the seat along the second traveling path so as to press the shield against the print-head. Movement of the sliding member along the first traveling path in a second direction results in removal of the shield from the print-head.

  • Patent number: 7088336
    Abstract: An improved pushbutton has a pair of elastic sections sandwiching a protrusive button. The elastic section includes a pair of elastic and flexible strips formed in an undulate manner to become a buffer member abutting a lateral side of the button to position the button in a vertical fashion. When the button is subject to a force the elastic sections may be compressed. When the force is released, the elastic sections are extended. The button may be embedded in a LCD panel at a smaller space, thus the overall size of the panel may be reduced.
