20090232316 | MULTI-CHANNEL BLEND SYSTEM FOR CALIBRATING SEPARATION RATIO BETWEEN CHANNEL OUTPUT SIGNALS AND METHOD THEREOF - A multi-channel blend system includes a calibration circuit and a decoding circuit having a gain amplifying module. The decoding circuit is utilized for receiving an input signal to generate a first channel output signal and a second channel output signal. The gain amplifying module is utilized for providing a gain value for determining a separation ratio between the first channel output signal and the second channel output signal according to a calibration signal. The calibration circuit is utilized for providing a predetermined test signal serving as the input signal so as to generate the calibration signal according to at least one of the first and second channel output signals generated from the predetermined test signal. | 09-17-2009 |
20090233566 | DEMODULATOR WITH OUTPUT LEVEL CALIBRATION - A calibration circuit for calibrating an output level of a demodulator includes a test signal generator, an RSSI module and a calibration module. The test signal generator generates a test signal, and the RSSI module detects the test signal to generate a control signal, wherein the control signal controls the demodulator to process the test signal to generate a determined output signal. The calibration module then calibrates the RSSI module according to the output signal in order to calibrate the output level of the demodulator. When the control signal is utilized to selectively enable or disable a soft-mute function of the demodulator, the calibration module can be utilized to calibrate or determine the soft-mute function of the demodulator. | 09-17-2009 |
20090252337 | MULTI-CHANNEL DECODING SYSTEMS CAPABLE OF REDUCING NOISE AND METHODS THEREOF - A multi-channel decoding method includes: receiving an input signal to generate a first channel output signal and a second channel output signal, wherein the input signal is mixed with a specific clock signal; and gradually changing an amplitude of the specific clock signal from a first value to a second value when switching from a first mode corresponding to a first number of channels to a second mode corresponding to a second number of channels. Systems utilizing the method and another method further comprising calibration are also disclosed. | 10-08-2009 |
20120076309 | MULTI-CHANNEL DECODING SYSTEMS CAPABLE OF REDUCING NOISE AND METHODS THEREOF - A multi-channel decoding method includes: receiving an input signal to generate a channel output signal; providing a first test signal serving as the input signal in a first calibration mode; and adjusting a DC voltage level of the channel output signal with a first calibration signal by reducing a difference between a first predetermined reference signal level and a DC voltage level of the channel output signal generated from the first test signal. | 03-29-2012 |

20120288317 | DOCUMENT-FEEDING ROLLER MECHANISM AND PRINTING APPARATUS HAVING THE SAME - A document-feeding roller mechanism includes a feeding roller assembly and a clamping-force adjusting module. The feeding roller includes a roller frame, a first roller unit, and a second roller unit. A document is conveyed by the first and second roller units through a printing module. The clamping-force adjusting module includes a cam unit and a resilient pressing unit. The resilient pressing unit is disposed between the roller frame and the cam unit. When the cam unit is rotated, the biasing force of the resilient pressing unit applied to the roller frame can be adjusted to change the document clamping force of the first and second roller units. Hence, just before a trailing end of the document is separated from the first and second roller units, the document clamping force can be reduced. | 11-15-2012 |

20110035398 | STREAMING QUERY SYSTEM AND METHOD FOR EXTENSIBLE MARKUP LANGUAGE - A streaming query system for extensible markup language is provided. An XPath query translator receives and analyzes a user-input XPath document. An abstract syntax tree analyzer establishes an abstract syntax tree. A XML parser receives and parses an XML document. An index generator generates an index for the XML document. A computation module performs a format calculation based on the abstract syntax tree and the index, and generates a query result accordingly. | 02-10-2011 |
20110173187 | CONFLICT OF INTEREST DETECTION SYSTEM AND METHOD USING SOCIAL INTERACTION MODELS - A conflict of interest detection system is provided. A data extractor retrieves a document and extracts author, title, and date information. A co-authorship finder finds out co-author relation among documents. A relevant group cluster identifies a key researcher in a particular field, and groups researchers connected to the key researcher as a group. A potential link finder identifies researchers who may have co-author relation. A relation filter filters out couples having weaker relation from the group having co-author relation. The filtered co-author relation data is then stored as a conflict of interest list. | 07-14-2011 |

20130034698 | METHOD FOR MANUFACTURING FLEXIBLE SUBSTRATE WITH SURFACE STRUCTURE COPYING FROM A TEMPLATE - Disclosed herein are a flexible substrate with surface structure and a method for manufacturing the flexible substrate. The disclosure relates to a low-cost process to manufacturing the flexible substrate that is adapted to the large-area mass production. According to one of the embodiments in the disclosure, the method introduces a mold with surface structure. An isolation material is formed on the mold surface in an earlier stage. Upon the isolation layer, a flexible substrate material is coated. After that, a baking step is employed to cure the flexible substrate material. The flexible substrate with surface structure is therefore formed after de-molding the cured substrate. Another aspect to the disclosure adopts the above-formed substrate to be a base substrate. A second flexible substrate with the surface structure identical to the mold is then formed by performing the above steps. | 02-07-2013 |
