20130192385 | DEVICE FOR MEASURING DROPLET MASS FLUX DISTRIBUTIONS TO TEST SPRAY INJECTION SYSTEM AND THE MEASURING METHOD - A technology to measure the mass flux distribution of liquid spray to evaluate droplet dispersion of a spray device for liquids such as fuel, paints, or coating agents, is disclosed. The apparatus for measuring spray mass flux to evaluate the droplet dispersion of the spray device includes a liquid spraying part including a spray nozzle to spray liquid, a spray collecting part to collect the liquid sprayed from the liquid spraying part, a transfer tube to transfer the liquid collected in the spray collecting part, a multi-cylinder part including a plurality of cylinders to receive the liquid collected in the spray collecting part, a movable mass measurement part to measure amass of each cylinder of the multi-cylinder part, and a mass flux calculating part to calculate a distribution graph of mass flux of the sprayed liquid. | 08-01-2013 |
20120292188 | SYSTEM AND METHOD FOR HIGH THROUGHPUT PARTICLE SEPARATION - The high throughput particle separation system includes an aqueous solution container for storing an aqueous solution containing specific particles to be separated, an electrode array, having a plurality of electrodes arranged at regular intervals or at various different intervals in series or in parallel, for deflecting specific particles simultaneously in a nonuniform electric field according to sizes and dielectric properties of the particles to separate a large quantity of the particles at high throughput, a path separation unit for establishing movement paths of the particles separated by the electrode array, and a control unit for applying the same voltage and frequency or different voltages and frequencies to the electrodes of the electrode array based on sizes and dielectric properties of specific particles to be separated. | 11-22-2012 |
20100245204 | CIRCULARLY POLARIZED ANTENNA FOR SATELLITE COMMUNICATION - A circularly polarized antenna includes a dielectric substrate having a first via array in the form of a cylindrical cavity, a micro-strip circular patch antenna located at the center of the cylindrical cavity and formed on the dielectric substrate to radiate a signal, and a rectangular dielectrically loaded waveguide having a second via array and serving to feed the signal to the micro-strip circular patch antenna. Accordingly, the circularly polarized antenna prevents impedance mismatch between the micro-strip antenna and the dielectrically loaded waveguide and broadens an impedance bandwidth thereof. | 09-30-2010 |
