Abstract: A motor may include a stator with a coil disposed on an inner side thereof, a rotor at least partially surrounded by the coil and having an accommodation space in which a refrigerant for cooling the coil may be accommodated, a shaft connected to the rotor to rotate integrally with the rotor, and a pipe communicating with the accommodation space so that the refrigerant may be introduced from an external source and the refrigerant flows into the accommodation space therethrough.

Abstract: A method for authentication, a user terminal and an authentication server for executing the same are disclosed. An authentication server according to an embodiment disclosed includes a number receiver that receives a number of a user terminal from a callee who has received a call originated from the user terminal, a device authenticator that determines whether to generate an authentication key based on the number of the user terminal received from the callee and a caller number received from the user terminal, and generates the authentication key when it is determined to generate the authentication key, and an authentication key transmitter that transmits the authentication key to the user terminal.

Abstract: A display device includes a plurality of pixels in which pixels located in a selected area emit light in a sensing pattern; a plurality of optical sensors generating sensing signals corresponding to the amount of light received; and a circuit determining amounts of deterioration of the plurality of optical sensors based on the sensing signals. The circuit determines a current deterioration degree based on the amounts, sets a light emitting luminance of the sensing pattern to a first value based on the current deterioration degree, and the first value is larger than a second value associated with a previous deterioration degree when the current deterioration degree is greater than the previous deterioration degree.

Abstract: An embodiment mounting and demounting device for a wireless electronic device includes a pair of holder wings arranged symmetrically to each other and configured to press both sides of the wireless electronic device, a holder wing adjusting device configured to apply a force to adjust a gap between the holder wings using a driving force of a drive motor, a lifting implementing device configured to interlock with the holder wing adjusting device to lift the wireless electronic device upward in a case in which the holder wings are spread apart by a predetermined reference gap or more, a lower housing wrapped around a lower side of the holder wings, the holder wing adjusting device, and the lifting implementing device, and an upper housing coupled to an upper side of the lower housing and configured to allow the wireless electronic device to pass through in an up and down direction.

Abstract: A motor driven air vent device for a vehicle can perform not only left/right angular rotation operation of a vertical wing for adjusting a left/right-directional airflow direction of air discharged indoors but also an opening/closing operation of a damper for interrupting or allowing an indoor discharge of air using a link bar for performing a straight line motion to the left or right thereof by driving a motor and a cam plate for angularly rotating by the link bar, etc. in a motor driven manner.

Abstract: A motor-driven air vent device for a vehicle is provided. The motor-driven air vent device connects a horizontal wing of an air vent to an output shaft of a driving motor through a link structure and rotatably operates the driving motor in the forward direction or the reverse direction by a touch type switch operation. Accordingly, the vertical angular rotation operation for the horizontal wing is automatically performed by the operation of the link structure delivering the torque of the driving motor.
