Abstract: A vehicle moving apparatus may include a housing extending in a first direction; an elevator coupled to the housing to be movable in the first direction and another direction opposite thereto, extending in a third direction and being inserted to be drawable into an underside space of a vehicle, and configured to lift or lower a wheel of the vehicle; and a wheel assembly coupled to the elevator and configured to move the housing and the elevator in a direction toward the vehicle or in a direction opposite the vehicle, wherein the wheel assembly includes a wheel rotatably provided with a vertical direction as an axis, and configured to movably support the elevator; and an actuator coupled to the wheel and configured to provide power for rotating the wheel, wherein the wheel is rotatable such that a diameter of the wheel is aligned between the first and third directions.

Abstract: A composite pad and a battery cell assembly and a battery module including the composite pad are disclosed. In some implementations, the battery cell assembly comprises a plurality of battery cells arranged in a direction, and one or more pads, each pad disposed between two adjacent battery cells of the plurality of battery cells, at least one of the one or more pads including a pad body with elasticity, and a heat generating part coupled to the pad body and connected to an edge of the at least one of the one or more pads and configured to generate heat upon application of electric power to the heat generating part.

Abstract: The present invention relates to a system and method for sharing and controlling various contents in a voice call. A contents sharing system includes a soft switch and a contents share server. The soft switch receives a voice call from a VoIP terminal to set establishment and cancellation on a voice call session, receives a contents sharing request call, and transmits the same to the contents share server. The contents share server in cooperation with the soft switch receives the contents request call and processes establishment and cancellation on a data session for contents sharing between the callers. Accordingly, improved calling is provided by sharing various contents between the callers in a voice calling and thereby overcoming the problem of communication only available for voice.

Abstract: Disclosed is a display driver including an input pad configured to receive a supply voltage, a wiring line connected to the input pad, a digital-to-analog converter configured to output analog signals based on digital-to-analog conversion results of data, a plurality of output buffer units configured to buffer the analog signals, and a plurality of bias controllers connected to different positions of the wiring line. Each of the bias controllers independently controls a bias voltage of a corresponding one of the output buffer units based on the supply voltage supplied through the wiring line.

Abstract: Disclosed is a half-power buffer/amplifier. The half-power buffer/amplifier includes first and second amplifying blocks respectively corresponding to first and second channels, a first output buffer unit controlled by an output from the first amplifying block, and a second output buffer unit controlled by an output from the second amplifying block. Each of the first and second amplifying blocks includes an input unit configured to amplify a first input signal, thereby outputting first and second currents, and an amplifying unit including a first current mirror, a second current mirror, and a bias unit connected between the first current mirror and the second mirror. Nodes in the first and second amplifying blocks are selectively connected to source/drain terminals of transistors in the first and second amplifying blocks in response to a control signal.

Abstract: The present invention generally relates to an Internet value-added service system and method for providing a conventional value-added service which has been provided in a web site with a message transmission medium of the Internet. More specifically, when an advertiser puts an advertisement through the message transmission medium of the Internet, the value-added service is also provided with the advertisement to improve advertising effects of the advertiser. Instead, SMS (short message service) is provided together in transmission of email to solve inconvenience of email reception, which results in replacement of email reception with the SMS.
