Abstract: A printed circuit board includes: a first board unit including a plurality of first insulating layers and a plurality of first wiring layers respectively disposed on or in the plurality of first insulating layers; a second board unit including one or more second insulating layers and one or more second wiring layers respectively disposed on or in the one or more second insulating layers; and a first passive device embedded in at least one of the first and second board units. The second board unit is disposed on the first board unit, and the first board unit has a second cavity passing through at least a portion of the plurality of first insulating layers on the first passive device based on a stacking direction of the plurality of first wiring layers.

Abstract: The present invention relates to a power plant early warning device and method which employ a multiple prediction model, and includes: a plurality of prediction models which receive information about the operation states of equipment in a power plant, and output prediction values and the reliabilities of the prediction values; a reliability analysis module which quantizes and analyzes the reliabilities output from the plurality of prediction models to determine the ranks of the plurality of prediction models, and calculates a final prediction value; a comparison module which compares the final prediction value with an actual measurement value, and outputs a residual; and a determination module which analyzes the residual to determine whether there are defects in the operating states of the equipment in the power plant.

Abstract: Provided is a novel compound capable of improving the luminous efficiency, stability and life span of a device, an organic electric element using the same, and an electronic device thereof.

Abstract: A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

Abstract: A clothes dryer includes a body having a filter opening at a front side of the body; a drum disposed in the body; a heat exchanger disposed in the body to exchange heat with air; a filter unit detachably mounted in the body through the filter opening; and a filter cover configured to be positioned between an open position where the filter unit is accessible through the filter opening and a closed position where the filter opening is covered by the filter cover. The filter cover includes a first coupling member. The filter unit includes a filter, a casing to support the filter, a front cover disposed at a front side of the casing, and a second coupling member disposed at the front cover. When the filter unit is mounted in the body the filter cover is maintained in the closed position by coupling the first and second coupling members.

Abstract: A clothes dryer with a filter unit and a filter cover having a coupling structure corresponding to each other. The clothes dryer includes a body, a drum installed inside the body, a drying unit configured to dry air passed through the drum, a filter unit disposed on the drying unit and detachably installed on the body, a filter cover fixed by provided with one side thereof being installed on the body and the other side thereof being coupled to the filter unit. When the filter unit is not assembled, a user may notice the filter unit not being assembled due to the filter unit and the filter cover, both of which are provided with a coupling structure corresponding to each other.
