Abstract: Embodiments relate to laser welding methods, monitoring methods, and monitoring systems for a secondary battery. A laser welding method for a secondary battery includes performing laser welding on a positive electrode base having a thin-film shape in which a plurality of positive electrode base tabs are formed at a side, a negative electrode base having a thin-film shape in which a plurality of negative electrode base tabs are formed at a side, and a thin-film multi-tab to be joined to each of the positive electrode base and the negative electrode base, a welded portion in which the multi-tab is welded with the positive electrode base and the negative electrode base being melting-joined by using a laser such that a plurality of welding spots is formed on the welded portion.

Abstract: Disclosed are a semiconductor device (1) including a MOSPET region and an integrated diode region, and a manufacturing method thereof. More particularly, a semiconductor device (1) including a silicon carbide (SiC) MOSPET region and an integrated Schottky bather diode that reduce forward voltage drop (Vf), device area, and switching oscillation resulting from parasitic inductance are disclosed.

Abstract: A scrubber system may include a scrubber housing including a vertically extended cleaning space, an inflow chamber coupled to a bottom portion of the scrubber housing, and first and second inflow portions, each of which is configured to supply a gas into the inflow chamber. The inflow chamber may include a mixing space, and the mixing space may be connected to the cleaning space. The first inflow portion may include a first connection pipe coupled to the inflow chamber to provide a first connection path and the second inflow portion may include a second connection pipe coupled to the inflow chamber to provide a second connection path. The first and second connection paths may be extended toward the mixing space in opposite directions, respectively, and may be connected to opposite portions of the mixing space, respectively.

Abstract: The present invention relates to a novel heterocyclic compound usable in an organic light-emitting device and to an organic light-emitting device comprising same, wherein [chemical formula A] is as described in the detailed description of the invention.

Abstract: An electronic device that interacts with a head mounted display (HMD) device is provided. The electronic device includes a communication interface, a memory, a display, and at least one processor electrically connected to the communication interface, the memory, and the display. The at least one processor is configured to receive an event signal related to sharing of contents with at least one external device or receive request information related to sharing of contents from the at least one external device through the communication interface, identify attribute information of the at least one external device, convert a format of some of one or more contents, which are stored in the memory, such that the format of one or more contents corresponds to the identified attribute information, and transmit the contents to the at least one external.

Abstract: An electronic device and method are disclosed herein. The electronic device includes a display, a memory and a processor. The processor implements the method, including displaying a first image through the display, storing screen information associated with the first image in a memory, detecting whether the electronic device is mounted on the wearable device, generating a second image corresponding to a view point of the first image based on the stored screen information, and displaying the generated second image through the display.
