Abstract: The present disclosure relates to a plug connector and a board-to-board connector, and a receptacle connector connected with a plug connector to electrically connect one pair of boards includes: a receptacle housing including: one pair of sidewall portions protruding along both side borders of a bottom portion facing each other; the other pair of sidewall portions protruding along the other both side borders of the bottom portion facing each other and connected with the one pair of sidewall portions; a center protrusion portion protruding from a center of the bottom portion; and a connection recess portion formed between the one pair of sidewall portions and the other pair of sidewall portions, and the center protrusion portion; a plurality of receptacle terminals coupled along insides of the one pair of sidewall portions, each of the receptacle terminals coming into contact with a terminal of the plug connector through a single contact point; and a receptacle metal shell including: fitting nail portions coup

Abstract: A wearable device that is worn on a user body includes a motion sensor to recognize a motion of the wearable device, a bending sensor to sense bending of the wearable device, a controller to generate a control signal according to a movement that is sensed by the motion sensor and the bending sensor, a communication unit to transmit the control signal to an external device, and, when an audio reproducing operation is adjusted according to the control signal in the external device, to receive a result of the adjusting from the external device, and a display to display the result of the adjusting. Accordingly, a content of the external device is easily adjusted.

Abstract: A digital photographing apparatus that is capable of detecting the shaking of the apparatus by using an autofocusing (AF) process and a method of controlling the digital photographing apparatus are provided. These involve calculating a first focal value while focusing on an object by performing the AF process and comparing the first focal value with a second focal value of a location on an image captured by actually photographing the object. This location corresponds to a location corresponding to the first focal value. As a result of these features, the shaking of the digital photographing apparatus can be detected.
