Abstract:
Provided is a high power super capacitor including: a bobbin; an electrode assembly being wound into the bobbin to be in a jellyroll type; a conductive connection member being formed in each of one end and another end of the electrode assembly using electric energy; and a plug being inserted into each of one end and another end of the bobbin, and being bonded with the conductive connection member using electric energy to be electrically connected to the electrode assembly. The electrode assembly may include a first electrode plate having a first polarity and including an inactive material area collector where the conductive connection member is formed in the one end of the electrode assembly, a second electrode plate having a second polarity and including another inactive material area collector where the conductive connection member is formed in the other end of the electrode assembly, and a separator being disposed between the first electrode plate and the second electrode plate to insulate between the first electrode plate and the second electrode plate. Accordingly, the high power super capacitor may increase a contact area without decreasing an area of electrode active material layer and may decrease an equivalent series resistance by forming a conductive connection member using electric energy, thereby enhancing an exothermic characteristic and being applied to a high power field.
Abstract:
A wind recognition system includes a sampling unit to sample data inputted through a microphone, an amplitude analysis unit to analyze an amplitude pattern of the sampled data, and a wind recognition unit to recognize the inputted data as wind if the analyzed amplitude pattern corresponds to a wind pattern. The amplitude analysis unit obtains amplitude data from the sampled data, and determines that the analyzed amplitude pattern corresponds to the wind pattern if the amplitude data includes n amplitudes each having a predetermined size. Alternatively, the amplitude analysis unit determines that the analyzed amplitude pattern corresponds to the wind pattern if a standard deviation of amplitudes included in the amplitude data is less than a reference deviation. Also, the wind recognition unit may recognize the inputted data as wind if the analyzed frequency spectrum of amplitude data corresponds to a wind prototype.
