  • Publication number: 20080201144
    Abstract: A method is disclosed in the present invention for recognizing emotion by setting different weights to at least of two kinds of unknown information, such as image and audio information, based on their recognition reliability respectively. The weights are determined by the distance between test data and hyperplane and the standard deviation of training data and normalized by the mean distance between training data and hyperplane, representing the classification reliability of different information. The method is capable of recognizing the emotion according to the unidentified information having higher weights while the at least two kinds of unidentified information have different result classified by the hyperplane and correcting wrong classification result of the other unidentified information so as to raise the accuracy while emotion recognition. Meanwhile, the present invention also provides a learning step with a characteristic of higher learning speed through an algorithm of iteration.

  • Publication number: 20080190889
    Abstract: The present invention discloses a method for manufacturing a roller with microstructure, comprising the steps of: forming a protective metal layer on a roller; defining specific imprint patterns on an imprint stamp by processing the imprint stamp with a flexible mold; forming an etch mask on the embossed imprint stamp after the imprint stamp is released from the mold; wetting the imprint stamp and the etch mask thereof; adhering the etch mask onto the roller by rolling the roller on the imprint stamp; etching the roller at the portion thereof uncovered by the etch mask; and forming the roller with specific microstructure by removing the etch mask and the protective metal layer.

  • Patent number: 7405501
    Abstract: An electric generator is disclosed, which comprises: at least a magnet, each having more than two poles; and at least a claw-pole set, each being composed of an inner claw-pole and an outer claw-pole; wherein, the inner claw-pole and the outer claw-pole are interlaced arranged and used for guiding magnetic flux; the inner claw-pole is connected to an iron core whose outer diameter is smaller than the magnet and thus the loop of the inner claw-pole and the outer claw-pole is conducted; the core is winded by a solenoid coil; the number of claws of the inner claw-pole is the half of the pole number of the magnet while the outer claw-pole is the same, so that, as the magnet is move relative to the claw-pole set, the magnetic flux passing through the solenoid coil will change continuously and thus an induction electromotive force is generated.

  • Publication number: 20070271791
    Abstract: A rolling mold for microstructured film imprinting includes a roller and a filmed metal template. The roller has a round outer surface. The filmed metal template is disposed with a microstructured film imprint pattern and changeably coupled to the roller by magnetic force or vacuum suction. Rolling of the roller allows the microstructured film imprint pattern to form a microstructured film, thus solving the drawbacks of the prior art.

  • Publication number: 20070167022
    Abstract: The present invention relates to a method of fabricating a vertical probe head, whereas the vertical probe head is formed by the combination of at least a probe, a bottom guide plate and a top guide plate having at least a hole matching the probe. The probe is fabricated by a LIGA-like process combining with the processes of photolithography, etching and electroforming, and so on, so that the probe is equipped with comparatively better precision, strength and reliability and yet can be custom-made for satisfying various demands. In addition, both the top and bottom guide plates are made by a means of non-mechanical machining, which respectively is fabricated by processing a substrate using means of photolithography, etching and mask so as to fabricate holes for matching with the aforesaid probe.
