Abstract: According to the present invention, light is irradiated to a finger of a subject and received from the finger of the subject to extract a pulse wave signal, generates an optimized pulse wave signal in a desired type by sampling the extracted pulse wave signal according to a predetermined sampling condition and normalizes the generated pulse wave signal, the entire segment of the normalized pulse signal is divided into a plurality of window segments to detect a pulse wave amplitude value with respect to a pulse wave signal for each window, a first eigenvector for each subject corresponding to a pulse wave amplitude value of the the entire window segment is extracted by using a LDA and then the first eigenvector per subject is compared with a threshold, determines distribution of eivenvectors for each subject compared to the threshold and thus a characteristic of the corresponding subject is diagnosed.

Abstract: The present disclosure provides a method for processing a video signal by using a linear relationship between transform types, the method comprising the steps of: determining a transform group on the basis of a prediction mode of a current block; parsing a transform combination index from the video signal, wherein the transform combination index indicates one of a plurality of transform combinations in the transform group; deriving a transform combination corresponding to the transform combination index, wherein the transform combination includes a horizontal transform and a vertical transform and includes DST-1 or DCT-5; performing inverse transform of the current block on the basis of the transform combination; and reconstructing the video signal by using the inverse-transformed current block.

Abstract: According to an embodiment of the present invention, there is provided a TCAM architecture in which a content-based search is conductible in such a manner that a search key to be searched for is used as an address of a memory element that makes up a TCAM cell and that an output from the memory element reflects whether a match or a mismatch is found as a result of the search. The memory element may be a look-up table.

Abstract: Disclosed are a method for generating personal identification information using an electrocardiogram and a method for identifying a person using the personal identification information. The methods dramatically increase an identification rate by using two-dimensional image data converted from an electrocardiogram signal as personal identification information, and enable real-time identification by reducing a calculation amount by converting only a single electrocardiogram cycle into the two-dimensional image data.

Abstract: A defect detection device enables easy removal of magnetic impurities. The defect detection device has a structure capable of effectively removing magnetic impurities adhered to a magnetic flux leakage detection device for nondestructive inspection of a small-diameter heat transfer tube or a partially saturated eddy current detection system. With the defect detection device, it is possible to minimize adhesion of magnetic impurities that deteriorate the performance of a leakage magnetic flux detection device for nondestructive inspection of a small-diameter tube of ferromagnetic metal material or a partially saturated eddy current detection system. Further, there is an advantage in that it is possible to remove the adhered magnetic impurities from the defect detection device easily.

Abstract: Disclosed are a fault-localization and error-correction method for a self-checking binary signed-digit adder and a digital logic circuit for performing the method. More specifically, a fault-localization and error-correction method for a self-checking binary signed-digit adder in which a stuck-at fault of the self-checking binary signed-digit adder may be detected at low cost and with low complexity and in which an error may be autonomously corrected using the self-dual concept, and a digital logic circuit for performing the method are disclosed.

Abstract: The present invention relates to a method and apparatus for providing digital background calibration for mismatches in M-channel time-interleaved ADCs(TI-ADCs), more specifically providing a pure digital blind calibration technique for offset mismatch, gain mismatch and time mismatch, which are essentially incurred by utilizing a time-interleaved analog-digital converter in systems having to process data with high speeds. Wherein the offset mismatch and gain mismatch are corrected based on statistical characteristics of the digital signals which are sampled and outputted in channel by channel, and the time mismatch is corrected based on a derivative filter and a delay filter. Thereby the present invention relating to a method and apparatus for digital background calibration enables the hardware complexity to be reduced and the efficiency of hardware resource to be increased. The pure digital background calibration of mismatches base on addition, subtraction and multiplication operations is also independent of foundaries and processes, and significantly reduces the design complexity.
