Abstract: Integrated processing of multimedia signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated multimedia system includes a main player that captures and processes signals digitally. The main player may adjust the audio signal to provide audio output of equal loudness across all frequencies by accounting for sensitivity of the human ear for sounds of varying frequencies. The main player can also account for perceived differences in loudness based on the angle of a listener to a speaker by detecting the position of a user and making an adjustment accordingly. The invention further provides a speaker that has embedded performance characteristics or an identifier that allows the system to provide an optimal speaker driving current for a particular system or determine how that speaker would be best implemented in the integrated system.

More particularly, the invention comprises a first step of analyzing a fraction extracted with a solid phase extraction method, a fraction obtained by extracting the remnant fraction with a liquid-liquid extraction method and fractions extracted with the liquid-liquid extraction method at two pH different from each other after the hydrolysis, with a gas chromatography-mass spectrometry; a second step of converting the chromatogram result into numerical values capable of being statistically processed; and a third step of analyzing the numerical values with a principal component analysis (PCA) and a discriminant analysis (DA) to detect a difference between the control group and the test group.

Abstract: A magnetic flux coupling-type superconducting current limiter is capable of protecting lines more effectively by winding reactors of a primary coil and a secondary coil in series in the structure where the primary coil and the secondary coils are wound in parallel in the conventional magnetic flux-lock type current limiter to increase a linked flux generated from an iron core. An electric conducting current which rapidly increases when a fault occurs is divided into the secondary coil and a superconducting coil to decrease a load on the superconducting element and it is opened more rapidly than the existing superconducting current limiter during a quench time such that it better limits a fault current.
