Abstract: Disclosed is a mobile negative pressure chamber, that includes a bed, a main cover separably coupled to the bed, and having a main cavity, an auxiliary cover coupled to one side of the bed to be separable, that seals the main cavity while being engaged with the main cover, and having an auxiliary cavity, in which a lower body of the surgical recipient is located in an interior thereof, a main treatment part provided in at least one of the main cover and the auxiliary cover, and provided with a glove mounted on an arm of the surgical operator, and an auxiliary treatment part provided in at least one of the main cover and the auxiliary cover, and into and from which the arm of the surgical operator or a medical instrument is inserted and extracted.

Abstract: Proposed is a leak detection method including a mode determination step of determining, by a mode determination part, an operating mode of a cooling system on the basis of information received from the cooling system, a reference level determination step of determining, by a reference level determination part, a reference level in a cooling water storage tank in the operating mode determined in the mode determination step, a leak determination step of determining, by a leak determination part, whether a leak has occurred by comparing the reference level determined in the reference level determination step and a cooling water level in the cooling water storage tank measured in real time, and a notification step of providing, by a leak notification part, leak information to a set terminal when it is determined that the leak has occurred in the leak determination step.

Abstract: The present disclosure provides a touch display device for minimizing viewing-angle-dependent variation in color coordinates. The touch display device includes a light-emitting element disposed in each of a plurality of subpixels including emission areas having different sizes, a plurality of touch electrodes disposed on the light-emitting element, and at least one opening formed in each of the plurality of touch electrodes. The width of the opening is formed differently in each of the plurality of subpixels including the emission areas having different sizes, thereby minimizing viewing-angle-dependent variation in color coordinates.

Abstract: A method for operating a memory device is provided. The method includes providing a high voltage signal to a memory cell array including a plurality of memory cells using a first wiring, providing a logic signal to the memory cell array using a second wiring, and providing a shielding signal to the memory cell array using a third wiring arranged between the first wiring and the second wiring. A highest voltage level of the logic signal is lower than a highest voltage level of the high voltage signal, and the shielding signal includes a negative first voltage level in a first mode and a positive second voltage level in a second mode.

Abstract: A display apparatus for a vehicle includes a cockpit part including an opening, a guide part mounted within the cockpit part, a display unit disposed within the cockpit part, moved along the guide part so that the display unit has a curved line-shaped moving path and configured to appear and disappear through the opening, and a driving part configured to provide electric power to the display unit so th

Abstract: Methods and apparatus for automating the fiber laying process during the repair of composite structures made of fiber-reinforced plastic material based on the three-dimensional printing technique. Continuous fiber rovings (e.g., carbon fibers) impregnated with liquid epoxy can be directly printed onto the damaged surface of the composite structure (e.g., an aircraft component made of carbon fiber-reinforced plastic) without human manipulation in an autonomous manner.
