Abstract: The present invention relates to methods for on-line calibrating output power of an optical pick-up. A power adjusting circuit of the optical pick-up has an optical power regulator and an optical power detector. The on-line output power calibrating method includes the steps of: performing a recording pre-process; providing a focus offset value and/or a tilt offset value to the optical pick-up; providing a setting value, corresponding to power under test, to the optical power regulator; detecting laser power emitted from the optical pick-up using the optical power detector; comparing the laser power with the power under test to adjust the setting value of the optical power regulator corresponding to the power under test; and performing an optimum power calibration if the laser power emitted from the optical pick-up conforms to the power under test.

Abstract: The present invention relates to a method for detecting a blank area of a power calibration area. The method includes the steps of: selecting a recording test area in the power calibration area; writing the recording test area with multiple stages of normal power and detecting power; forming multiple normal blocks and detecting blocks, wherein each of the detecting blocks includes one unit of unrecorded block and one unit of recorded block; and reading information from the unrecorded blocks of the detecting blocks and thus determining whether the unrecorded blocks of the detecting blocks are blank or not. Once all the unrecorded blocks of the detecting blocks are determined to be blank, it represents that the selected recording test area is totally blank.

Abstract: A displaying device at least comprises a thin film transistor (TFT); a first electrode controlled by the TFT; a first capacitor electrode and a second capacitor electrode electrically connected to each other through the first electrode. The first electrode has a first slit. The first slit is positioned between a first zone and a second zone, wherein the first zone connects the first capacitor electrode and the first electrode, and the second zone connects the second capacitor electrode and the first electrode. If a defect is observed, a portion of the first electrode is removed for isolating the first capacitor electrode and the second capacitor electrode.

Abstract: The invention, the manufacturing process and operation method for forming the streptavidin surface acoustic wave (SAW) immunosensor apparatus is disclosed. Firstly, the PZT film is formed on silicon substrate by using the micro-powder-sol-gel method. Then, the metal transducer electrodes are coated on the PZT film using semiconductor process technology to produce the SAW. Finally, the sensing area of the SAW element is modified by streptavidin to form the streptavidin SAW immunosensor. The invention could be used for examining the ligand decorated by biotin, also for examining antibody.

Abstract: An analog-to-digital converter (ADC) having a two-channel or multi-channel structure processes background timing calibration. Signals from the ADC are directly compared for the calibration. Additional signal or interruption of circuit is not required. A dynamic calibration is processed. A timing-skew error is kept in a low level and a process mismatch is not a concern. Moreover, sampling frequency and input signal frequency are improved. A high sampling frequency and a high speed of signal inputting are achieved; and chip area can be greatly shrunk because the extra calibration circuits are simple digital circuits.
