摘要： A detector is scanned across an optical storage medium having groove tracks and land tracks, each track having a wobble structure, to detect light reflected from the optical storage medium. A wobble signal and a tracking error signal are generated based on an output of the detector, and the wobble signal is sampled according to the tracking error signal. A determination about whether the detector is at the groove track or the land track is made based on the tracking error signal and a comparison of sampled values of the wobble signal.

摘要： The invention relates to the structures of proton exchange membranes with different molecular permeabilities, especially to the proton exchange membranes suitable for the applications in Direct Methanol Fuel Cell (DMFC) and with the function of recovering water from the cathode. The polymeric structures are the designs of phase separated structures of the crystalline phase and the amorphous phases, thereby limiting the swelling of the materials and the space of ionic cluster structures in nano-scale to reduce the permeability of methanol fuels. On the other hand, by controlling of polymeric grafting reactions result in the reverse (from the cathode to the anode) permeability of the product water molecules on the cathode in the proton exchange materials greater than the permeability of methanol molecules in the fuels (from the anode to the cathode) due to the differences of fuel concentrations between the cathode and the anode of DMFC. Hence, it has the function of recovering water of the cathode and does not have the over-permeable phenomena as seen in methanol molecule.

摘要： A high-speed optical disc recording apparatus includes a laser diode for generating multi-pulse light pulses and a photodiode outputting a measured power of the light pulses. An NRZI pattern encoder generates a predetermined power control pattern causing a write strategy generator to generate write strategy to a laser diode driver such that the laser diode outputs a multi-pulse having a fixed-duty ratio with two power levels. The measured power is averaged with a low-pass filter, is sampled and held, and is calibrated according to the fixed-duty ratio. The calibrated held average output of the measured power of the light pulses is compared with predetermined present levels to control the laser diode driver output voltage.
