20100295633ELECTROMAGNETIC BANDGAP PATTERN STRUCTURE, METHOD OF MANUFACTURING THE SAME, AND SECURITY PRODUCT USING THE SAME - Disclosed herein is an electromagnetic bandgap (EBG) pattern structure, including: a nonconductive substrate; and a pattern assembly formed on the substrate and including regularly arranged closed-loop patterns and open-loop patterns both of which are made of a conductive material. The EBG pattern structure is advantageous in that it can be used to manufacture new security products by applying its frequency characteristics to securities or IDs and in that it can be variously used in security technologies for preventing forgery and alteration because various security codes can be created by adjusting the variables of its EBG pattern.11-25-2010
20110108617APPARATUS FOR RECOGNIZING SECURITY CODE HAVING ELECTROMAGNETIC BAND-GAP PATTERN - In an apparatus for recognizing a security code having an electromagnetic band gap (EBG) pattern which uses reflection and transmission characteristics of the EBG pattern, a voltage controlled oscillator generates a signal to a power divider, which divides the power of the signal into halves, and outputs a first signal through a waveguide to be incident on the EBG pattern. The waveguide receives a signal reflected from the EBG pattern and outputs the reflected signal to a phase detector. A circulator outputs the second signal to the phase detector, which detects the phase difference between the reflected signal and the second signal, and outputs phase difference data to a data control unit, which determines whether the security code having the EBG pattern is recognized using the phase difference data. In an alternate embodiment, the voltage control oscillator is controlled to sequentially generate signals using power difference data.05-12-2011

20090018803METHOD OF CLOTH SIMULATION USING LINEAR STRETCH/SHEAR MODEL - Deformations occurring in cloth can be decomposed into two components: the in-plane and the out-of-plane deformations. Stretch and shear are in-plane deformation, and bending is out-of-plane deformation. In the method, the numerical simulation can be done in real-time, and the models fix some flaws that existed in previous real-time models, leading to conspicuous reduction of artifacts.

20100215235METHOD FOR POPULATION-DRIVEN IDENTIFICATION OF BODY LANDMARKS - A new method for the identification of body landmarks from three-dimensional (3D) human body scans without human intervention is provided. The method is based on a population in whom landmarks were identified and from whom 3D geometries were obtained. An unmarked body (subject) is landmarked if there is a landmarked body in the population whose geometry is similar to that of the subject. The similarity between the surface geometry of the subject and that of each individual in the population can be determined. A search is performed using the mesh registration technique to find a part-mesh with the least registration error; the landmarks of the best-matched result are then used for the subject.08-26-2010

CIP is a high-order fluid advection solver that can reproduce rich details of fluids. It has third-order accuracy but its computation is performed over a compact stencil. A novel modification of the original CIP method that fixes all of the above problems without increasing the computational load or reducing the accuracy is provided. The proposed method brings significant improvements in both accuracy and speed.09-30-2010
20110112800Method for Simulating Stretching and Wiggling Liquids - A method for simulating the stretching and wiggling of liquids is provided. The complex phase-interface dynamics is effectively simulated by introducing the Eulerian vortex sheet method, which focuses on the vorticity at the interface and is extended to provide user control for the production of visual effects. The generated fluid flow creates complex surface details, such as thin and wiggling fluid sheets. To capture such high-frequency features efficiently, a denser grid is used for surface tracking in addition to coarser simulation grid. A filter, called the liquid-biased filter, is used to downsample the surface in the high-resolution grid into the coarse grid without unrealistic volume loss resulting from aliasing error.05-12-2011
