Abstract: Disclosed herein is an apparatus and method for detecting an emotional change through facial expression analysis. The apparatus for detecting an emotional change through facial expression analysis includes a memory having at least one program recorded thereon, and a processor configured to execute the program, wherein the program includes a camera image acquisition unit configured to acquire a moving image including at least one person, a preprocessing unit configured to extract a face image of a user from the moving image and preprocess the extracted face image, a facial expression analysis unit configured to extract a facial expression vector from the face image of the user and cumulatively store the facial expression vector, and an emotional change analysis unit configured to detect a temporal location of a sudden emotional change by analyzing an emotion signal extracted based on cumulatively stored facial expression vector values.

Abstract: An air conditioning device for a vehicle includes: a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the inflow space; a blowing unit disposed at the inflow space of the housing and configured to blow air; a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air; and an opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports. The air conditioning device adjusts the temperature of conditioned air for respective modes and reduces a flow resistance of air.

Abstract: An integrated circuit package system comprising: providing a substrate; forming a base assembled package over the substrate; forming a top package over the base assemble package; and applying a top package stacking material for stand-off or insulation to the base assembled package and the top package.

Abstract: Disclosed herein are a balancer which is provided with a curved portion at a balancing space so that movement of balls is accelerated at the moment a rotational speed of a rotor exceeds a resonant speed, thereby stabilizing the rotation of the rotor without vibration regardless of when the rotational speed of the rotor is less or more than the resonant speed, and a centrifuge using the above balancer. The balancer includes a body which is formed with a balancing space thereinside. The balancing space has a circular circumference, and is defined by a bottom portion, a slanted portion extending upward from the bottom portion, a curved portion formed at an end of the slanted portion, and an upper large-diameter portion extending from the curved portion. The balancer further includes a plurality of balls which are contained in the balancing space.
