Abstract: A power supply control apparatus is connected to an electric device to control supply of power to the electric device. The apparatus includes a main power switch to apply or interrupt main power to the electric device, the main power being external input commercial AC power, an auxiliary power storage unit supplied and charged with the main power as auxiliary power, a charging/discharging unit including a charging circuit to convert the main power into DC power and charge the converted DC power in the auxiliary power storage unit, and a discharging circuit to convert the DC power in the auxiliary power storage unit into AC power and discharge the converted AC power to the electric device, and a controller to control the main power switch, and control the charging/discharging unit to selectively drive the charging circuit or the discharging circuit.

Abstract: A radio-frequency-identification (RFID) system includes an RFID tag and an RFID reader, where the RFID reader is configured to communicate with the RFID tag using time-hopped pulse-position modulation and ultra-wideband modulation. The time-hopped pulse-position modulation includes sending from the RFID tag to the RFID reader a series of pulses in time slots selected by the RFID tag through a cryptographically secure pseudo-random generator.

Abstract: Disclosed herein is a method of fabricating nano-components using nanoplates, including the steps of: printing a grid on a substrate using photolithography and Electron Beam Lithography; spraying an aqueous solution dispersed with nanoplates onto the grid portion to position the nanoplates on the substrate; depositing a protective film of a predetermined thickness on the substrate and the nanoplates positioned on the substrate; ion-etching the nanoplates deposited with the protective film by using a Focused Ion Beam (FIB) or Electron Beam Lithography; and eliminating the protective film remaining on the substrate using a protective film remover after the ion-etching of the nanoplates, and a method of manufacturing nanomachines or nanostructures by transporting such nano-components using a nano probe and assembling with other nano-components.

Abstract: A plasma display device having a heat sink. The heat sink includes a heat sink base adapted to contact a semiconductor device and a plurality of fins extending from the base. Each fin has a fin base and a fin tip distal from the semiconductor device. The fin base is integrally formed with the heat sink base and a fin base width is larger than a fin tip width. The fin base may be tapered toward the fin tip. Alternatively, the fin base may have a constant width and the fin tip may have a constant width.

Abstract: The present invention relates to gold nanoparticles which can be produced at low costs with high yields in large amounts by a liquid phase synthesis method and have a controlled size, as well as a synthesis method thereof. The inventive gold nanoparticles consist of gold nanoplates having a polygonal or circular plate structure.
