  • Publication number: 20100105328
    Abstract: A method for providing information by an information providing device with a Bluetooth module in an information broadcast service based on Bluetooth. The method includes broadcasting an inquiry signal to provide the information; receiving an inquiry response signal; determining if a broadcast request is included in the inquiry response signal; and delivering the information to a Bluetooth device that sent the inquiry response signal, when a broadcast request is included in the inquiry response signal.

  • Publication number: 20100093280
    Abstract: A Bluetooth® connection method and a Bluetooth module for discovering and connecting peripheral Bluetooth devices. An inquiry signal is sent with a minimum transmit power. It is determined if an inquiry response signal is received for a waiting time. A path loss corresponding to each inquiry response signal is calculated when a plurality of inquiry response signals are received for the waiting time, the calculated path losses are compared, and Bluetooth® connection is performed with a Bluetooth® device that sent an inquiry response signal having a lowest path loss.

  • Publication number: 20050248433
    Abstract: A fusible resistor and method of fabricating the same is provided. The fusible resistor has a very low resistance of 20 to 470 m? by depositing thin films as a fusible element made of a material with low resistivity such as copper having a temperature coefficient of over 2,000 ppm/° C. The fusible resistor comprises a resistor body, a fusible element layer formed to surround the resistor body, caps formed to surround ends of the fusible element layer, lead wires attached to the caps, and an insulating layer for insulating the fusible element layer and the caps from outside. The thus-fabricated fusible resistor performs all functions of a use without generating excessive heat.

  • Patent number: 6702918
    Abstract: A rapid prototyping process and apparatus that provides an intermittent material feed type variable-lamination rapid prototyping using a linear thermal cutting system, wherein intermittently fed materials are cut to have variable lengths, widths, and lateral gradients with the 4-axis control-type linear thermal cutting system controlled by a computer, and based on cutting operation data generated in the computer.

  • Patent number: 6627030
    Abstract: Disclosed herein is a variable lamination manufacturing process and apparatus. The method comprises the step of coating strip-shaped material with an adhesive while the strip-shaped material is fed. Thereafter, the strip-shaped material being fed is cut into material pieces of a variable width, variable inclinations and a variable length in accordance with the three-dimensional computer aided design data of a three-dimensional product using a linear heat source. The cut material pieces are stacked on a moving table to be positioned in the corresponding positions of the three-dimensional product. Finally, the stacked cut material pieces are pushed to bond one piece to anther.
