摘要： The invention provides an apparatus for controlling servo signal gains of an optical disc drive. The apparatus adjusts the gains of a plurality of servo signals controlling a servo system of the optical disc drive according to a closed-loop mode or a state-reloading mode whenever the optical disk drive encounters an operating state transition. In closed-loop mode, at least one AGC loop of the apparatus compensates the gains of the servo signals with a selectable bandwidth during a specific period after the operating state transition to accelerate the convergence of the servo signals. In state-reloading mode, at least one AGC loop of the apparatus reloads the previously saved convergence values or pre-determined values as the initial values according to the current operating state immediately after the operating state transition to accelerate the convergence of the servo signals.

摘要： The invention provides an apparatus for demodulating an Address In Pre-groove (ADIP) symbol. The ADIP symbol is carried by a wobble signal of an optical disk and comprises a series of ADIP bits permuted according to one of a plurality of permutation patterns to make up the ADIP symbol. A wobble extraction module extracts the wobble signal from the optical disk. A reference wobble generator generates a reference wobble with the same frequency and phase as a fundamental frequency and phase of a positive wobble cycle of the wobble signal. A waveform difference measurement module then measures a difference between the wobble signal and the reference wobble to obtain a series of difference measurement values respectively corresponding to the ADIP bits. A pattern matching module then compares probabilities of the permutation of the ADIP bits agreeing with each of the permutation patterns according to the difference measurement values to determine the ADIP symbol.

摘要： An encapsulation composition for pressure signal transmission including a flexible and low modulus epoxy resin as a substance in combination with plastic balls with pressure signal transmission properties as filler is provided. Therefore, the pressure signal is transmitted by utilizing the property of easy deformation of the flexible epoxy resin under pressure. And the effect of signal transmission is enhanced by the contact between plastic balls. The encapsulation composition is used in a sensor for transmitting pressure signals. The encapsulation composition is hydrophobic, so an electronic device of the sensor can be protected against moisture or water to extend its lifetime. Compared with traditional sensors using liquid for transmitting pressure signal, this sensor using solid encapsulation composition has advantages such as easy production and processing.
