    摘要: An apparatus and method for lossless audio compression/decompression through entropy coding are provided. The apparatus comprises a buffer, a time-axis predictor, and a bit-allocation entropy coder/decoder, wherein the time-axis predictor is capable of subtracting the predicted value of a current input signal value from its original value, thereby generating a predicted error signal. The predicted error signal is then input into the bit-allocation entropy decoder in accordance with a coding guideline, and in turn is coded into data blocks with different lengths. Further, the data blocks after entropy coding comprise a 32-bit header and the real data following the header, wherein the real data is substantially a discrepancy between the prediction error of the data and the minimum value of each data block.

    摘要: The present invention discloses a multiple-beam holographic optical pick-up head, which has the advantages of the multiple-beam optical pick-up head and the holographic optical pick-up head and can increase the light usage efficiency. This invention uses the property that a polarized diffractive optical element can generate different optical effects for laser beam with different polarizations and places a polarized multiple-beam grating and polarized hologram on the optical path for splitting the incident light toward the disc into multiple reading beams by the multiple-beam grating. The returning laser beams reflected from the disc are diffracted and diverted by the hologram to reach a photodetector. Both the incident and reflective beams are diffracted once only; thus the light usage efficiency can be increased.

    摘要: A magneto-resistance transistor including a magneto-resistant element which may function as an emitter and a passive element which may function as a collector. The base may be interposed between the passive element and the magneto-resistant element, thereby coupling the passive element with the magneto-resistant element. A magnetic field of a given strength may be applied to at least a portion of the magneto-resistant transistor, the given strength determining a resistance in the at least a portion of the magneto-resistant transistor. Thus, by adjusting the given strength of the magnetic field, the resistance may be adjusted. Therefore, different emitter current inputs may be achieved with a fixed voltage. Further, a base current may vary with a controlled variation of the emitter current input.
