Abstract: Provided is a neural device including at least one nano-wire. The neural device includes a nano-wire formed on a base formed on a first surface of a substrate, and an electrode pad formed on a second surface different from the first surface of the substrate and configured to output an electrical signal gained from a neural fiber through the nano-wire or apply a signal for an electric stimulus to the nano-wire. Therefore, it is possible to prevent the nano-wire from becoming embedded in an encapsulation and maximize a contact between the nano-wire and a nerve.

Abstract: A polymer composition includes a polyarylene sulfide resin, a olefinic graft copolymer, and a fluorinated polyolefin resin. Some embodiments may additionally comprise an epoxy compound and/or a filler. In some embodiments, the compositions have good flame retardancy, impact strength, and flexural strength.

Abstract: Provided are digital multimedia data recording/playback device and operation method thereof. The device includes a user interface, an HDD, and a system controller. The user interface selects a source apparatus having a recording medium on which multimedia data to be copied is stored, and a target apparatus for which a copy operation is performed and having a recording medium on which the multimedia data is to be stored, according to a user's selection. The HDD temporarily stores the multimedia data that has been selected as a copy object, and the system controller copies the multimedia data temporarily stored in the HDD to the selected target apparatus.

Abstract: A test apparatus having an auto probe and a test method using the same reduces difficulties in defect detection which are caused by a manual test by operators. The test apparatus includes an auto probe unit that contacts a panel of a display device. A test pattern is input to the panel. A vision unit installed above the panel collects a pattern displayed on the panel. A computer system analyzes and determines information about the collected pattern. Whereas the panel was previously tilted from a horizontal position and then examined by the operator manually, in the present test method a movable camera installed at an auto probe apparatus permits testing while the panel is in the horizontal position.

Abstract: An apparatus and method for inspecting a liquid crystal display device is provided. The apparatus includes: a camera photographing a front surface of a liquid crystal panel; a back light irradiating light to the liquid crystal panel; a diffuser sheet diffusing the light generated from the back light; a prism sheet converting the diffused light so as to be perpendicularly incident to a rear surface of the liquid crystal panel; a probe unit applying an inspection signal to the liquid crystal panel; and a frequency converter converting a frequency of the light generated from the back light. The apparatus for inspecting the liquid crystal display device according to the invention detects bad sub-pixels, impossible to detect with the naked-eye, improving the quality of the liquid crystal display device.

Abstract: To compliment the drawback of the conventional large-size reserve battery cell inapplicable to a small electronic system, disclosed is a super-slim reserve battery cell sized merely several millimeters in its entirety including micro-size battery elements sized about several ?m by using a micro-machining technology of processing mechanical structures in a super-slim size. The present invention realized electrolyte container and other battery elements by using materials such as silicon, nickel, copper, aluminum, etc. to form a membrane structure of relatively thinner thickness than the periphery in an electrolyte container contiguous with the battery cell that is broken only when activating the cell. Therefore, it is possible to activate the battery cell with less power while securing sufficient impact-resistant characteristics under normal circumstances.
