Abstract: A system for managing a seat occupancy status by a passenger and a control method of the system includes a seat belt sensor provided for each seat to detect a fastening or unfastening of the seat belt, a pressure detection unit provided for each seat to detect occupancy or non-occupancy of a seat by a passenger and pressure of the seated passenger, a secondary control unit provided for each seat and woken up by radio communication with a vehicle to alert to an unfastened state of the seat belt when the seat belt is unfastened upon determining, by a seat belt sensor, whether the seat belt is fastened, and a primary control unit provided in the vehicle to perform radio communications with each secondary control unit and check an abnormality based on reception or non-reception of the system data transmitted from the secondary control unit.

Abstract: An all-solid-state battery having an increased lifespan is equipped with a pressure pad layer. More particularly, the all-solid-state battery includes a unit cell and a pressuring pad layer. The unit cell is composed of a cathode, an anode, and a solid electrolyte layer positioned between the cathode and the anode. The pressurizing pad layer is positioned on each side of the unit cell and includes a non-porous upper layer, a non-porous lower layer, and a porous core layer positioned between the non-porous upper layer and the non-porous lower layer.

Abstract: A display device includes: a first substrate including emission areas and a peripheral area surrounding the emission areas; a light emitting element layer on the first substrate and overlapping the emission areas; a plurality of light control patterns overlapping the emission areas and the peripheral area and on the light emitting element layer; and a transmission pattern between the plurality of light control patterns and having a refractive index of about 1.2 or more and less than about 1.5.

Abstract: A method and a system thereof for producing a digital holographic screen based on multi-hogel printing are proposed. The system includes a light source unit including lasers, a dichroic mirror for RGB three color matching, mirrors, a beam splitter, and an optical shutter, an object beam unit including a spatial filter, a lens, and a mirror, a reference beam unit including a spatial filter, a lens, and a mirror, a diffuser fixing unit including a diffuser holder and a diffuser positioned between the object beam unit and a recording material and configured to scatter and diffuse the object beam, a photomask movement unit including a photomask holder, an XY-translation stage, and a photomask positioned between the reference beam unit and the recording medium and on which a grid-shaped on/off binary pattern is printed, and a controller configured to control the optical shutter and the XY-translation stage.

Abstract: A display device is disclosed that includes a substrate including light emitting areas and a peripheral area surrounding the light emitting areas, a light emitting element layer disposed on the substrate and overlapping the light emitting areas, an encapsulation layer disposed on the light emitting element layer and a first pattern layer disposed on the encapsulation layer, and including first extension parts extending in a first direction and first connection parts connecting adjacent first extension parts among the first extension parts to each other.

Abstract: A battery module includes at least two cell assemblies, a module housing having an upper cover formed by a top portion and a first side portion extending downward from a first side edge of the top portion, a first gas passage formed between the first side portion of the upper cover and a first side of the at least two cell assemblies for circulation of gas generated from the at least two cell assemblies, and a flame retardant plate in the first gas passage and extending between the at least two cell assemblies and the module housing, wherein the first side portion of the upper cover is coupled to the flame retardant plate.

Abstract: In a security card check type computer security method, it is determined whether a predetermined check condition for checking a right of a security card to use a computer, which stores at least security information enabling the identification of the right of use of computer, is satisfied and a combination key requiring checking is generated. When the combination key is received, check result data with respect to the security card is waited for. The security information of the security card is checked to obtain the check result data. The right of use of computer is controlled depending on the check result data.

Abstract: A control system for an automatic shutdown of a power supply constructed with a switching mode power supply (SMPS) receiving an AC voltage and converting the AC voltage into a DC voltage; a main board receiving the DC voltage output from the switching mode power supply; and a control circuit controlling and maintaining the supply of power from the switching mode power supply to the main board until a shutdown process is performed when power is turned OFF, wherein the control system enables the automatic shutdown of a power supply while preventing a file or a system from being damaged by automatically cutting off power after performing the shutdown process by the power control system even though the power switch is turned OFF due to the carelessness of the user or an external factor.
