Abstract: A linear compressor for producing a driving force by magnetic induction and naturally modulating a cooling capacity according to a load includes a fixed member provided with a compression space, a movable member which linearly reciprocates inside the fixed member to compress refrigerant, a plurality of springs installed to elastically support the movable member in a motion direction, a first stator through which a current flows, a conductor member magnetically induced by the first stator to make the movable member linearly reciprocate, and a control unit which controls supply of a current with respect to the first stator.

Abstract: A linear compressor includes a fixed member provided with a compression space, a movable member which linearly reciprocates inside the fixed member to compress refrigerant, one or more springs installed to elastically support the movable member in a motion direction, a first stator applied with a current to produce a magnetic field, a second stator spaced apart from the first stator at a certain interval, a conductor member electromagnetically induced by the magnetic field produced by the first stator and the second stator to make the movable member linearly reciprocate, and a control unit which controls supply of the current with respect to the first stator.

Abstract: The present invention relates to a linear compressor, and more particularly to, a linear compressor which employs a conductor member in a linear motor instead of a magnet to produce a driving force by electromagnetic induction. The linear compressor of the present invention includes a fixed member provided with a compression space, a movable member which linearly reciprocates inside the fixed member to compress refrigerant, one or more springs installed to elastically support the movable member in a motion direction, a stator composed of a first stator supplied with a current, and a second stator spaced apart from the first stator at a certain interval, a conductor member electromagnetically induced by a magnetic field produced by the stator to make the movable member linearly reciprocate, and a control unit which controls supply of the current with respect to the first stator.

Abstract: A method of controlling an image data output of a portable device, a portable device having a signal detection unit and image processing unit are provided. The signal detection unit generates a photographing-disabled mode signal in response to a restricted area signal. The image processing unit has a photographing-disabled mode decision unit, an authentication decision unit and a control unit. The photographing-disabled mode decision unit determines whether the portable device is in the photographing-disabled mode or not based on the photographing-disabled mode signal. The authentication decision unit determines whether the portable device is authenticated or not when the portable device is in the photographing-disabled mode. The control unit outputs first photographed image data when the portable device is authenticated, and prohibits an output of the first photographed image data when the portable device is not authenticated.
