The plasma generator includes a plate-shaped lower electrode for seating a substrate; and a cylindrical rotating electrode on the plate-shaped lower electrode, wherein the cylindrical rotating electrode includes an electrically conductive body that is connected to a power supply and includes a plurality of capillary units on an outer circumferential surface of the electrically conductive body; and an insulation shield layer that is made of an insulation material or a dielectric material, exposes a lower surface of the plurality of capillary units, and shields other parts.
Abstract:
An apparatus for displaying acupuncture points according to the present invention recognizes a curved surface of a human body via 3D scanning, and then sets acupuncture points corresponding to the body surface that has been recognized to project them onto the body. More specifically, the apparatus for displaying acupuncture points comprises: a 3D scanner for performing 3D scanning; a control unit for setting acupuncture points by using the data that has been scanned by the 3D scanner; and a projection unit for projecting the acupuncture points that have been set by the control unit onto the body. Accordingly, the present invention allows accurate selection of acupuncture points on a highly curved surface of a human body.

Abstract:
A Wireless-Fidelity (Wi-Fi) service method and system are provided. A beacon message and probe response message may contain a service information field storing device information. Wi-Fi devices can exchange information on supported functions with each other and one Wi-Fi device may identify functions supported by another Wi-Fi device. Hence, a Wi-Fi connection can be set up through automatic provisioning. The method includes receiving, by a first Wi-Fi device in non-Access Point (AP) mode, messages from nearby Wi-Fi devices operating in AP mode, analyzing a service information field of each received message, determining a second Wi-Fi device that is manufactured by the same manufacturer as the first Wi-Fi device and is capable of supporting a requested service, establishing a connection with the second Wi-Fi device through Wi-Fi Protected Setup (WPS) based on automatic provision, and sending data associated with the requested service to the second Wi-Fi device for a Wi-Fi service.
Abstract:
A memory device includes a data block storing first data, and a log block storing second data that is an updated value of the first data. A spare area of the log block stores a first mapping table including mapping information between the first data and the second data.
Abstract:
An obstacle sensor includes a line light irradiating unit including a light-emitting unit, a light-emitting driving unit to drive the light-emitting unit, and a first conical mirror, an apex of which is disposed towards the light-emitting unit in a light irradiation direction of the light-emitting unit and which converts light emitted from the light-emitting unit into line light irradiated in all directions, and a reflected light receiving unit including a second conical mirror to condense light, that is irradiated from the first conical mirror and is then reflected from an obstacle, a lens, that is spaced from the apex of the second conical mirror by a predetermined distance and transmits the reflected light, an imaging unit to image the reflected light that passes through the lens, an image processing unit, and an obstacle sensing control unit.
Abstract:
A plasma generating system is provided. The plasma generating system includes: a pair of electrodes having distal ends; an electrode holder holding the pair of electrodes; a gate having a surface on which the electrode holder is slidably mounted and adapted to be controlled by sliding the electrode holder on the surface; and a resilient member secured to the gate and adapted to generate a force to close the opening. The distal ends are adapted to move into an opening of the gate as the electrode holder slides along a direction on the surface and adapted to generate an electric arc to thereby ignite plasma in a gas.
Abstract:
A mobile device and a method for providing a tethering service via a security mode and a list of preferred mobile devices are provided. The method includes determining, when the mobile device receives a connection request from a client mobile device, a number of client mobile devices that are currently connected to the mobile device, determining, when the number of connected client mobile devices is less than a preset maximum connection number, the number of created Basic Service Sets (BSSs), determining, when the number of BSSs is less than a preset maximum creation number, the identification-information regarding the client mobile device that requested connection, and providing a tethering service to the client mobile device according to the determined identification-information.
Abstract:
An oxide semiconductor includes a first material including at least one selected from the group consisting of zinc (Zn) and tin (Sn), and a second material, where a value acquired by subtracting an electronegativity difference value between the second material and oxygen (O) from the electronegativity difference value between the first material and oxygen (O) is less than about 1.3.
Abstract:
A robot cleaner which does not stop to change a traveling direction thereof, and a control method thereof includes setting a territory about which cleaning will be performed based on position data acquired during traveling about a cleaning area, predetermining a cleaning path to clean the territory about which cleaning will be performed, and if the cleaning path includes a zigzag traveling path, changing the traveling direction of the robot cleaner by executing curved traveling of the robot cleaner during traveling along the zigzag traveling path, thus decreasing the time required to clean an area during a change of the traveling direction of the robot cleaner.
