An electronic device is provided. The electronic device includes a frame and a display member exposed through an opening of the frame. The display member includes a first glass exposed through the opening to an outside and a second glass disposed on a surface of the first glass. The second glass includes an area formed to project beyond an edge of the first glass such that the area is positioned inside the frame.

Electronic device

The present invention discloses a universal dock having a universal cradle for cradling a portable terminal having various sizes and types or accessory thereon, and a connector dummy receiving a connector for electrically connecting to the portable terminal and moving upward and downward on the universal cradle.

Universal dock for portable phone

A docking station for an electronic device is provided. The docking station includes a housing having an inner space, a rotator disposed in a rotatable manner inside the housing, and partially exposed outwardly to the housing when completely open, a movable member coupled to the rotator, and exposed together with a device mounting groove for mounting an electronic device thereon when the rotator is completely open, and a stopper coupled to the movable member to selectively control the movable member so that a position of the movable member is fixed when the rotator is completely open and so that the movable member moves in a closing direction together when the rotator is closed.

Docking station

A stylus pen for inputting data of an electronic device includes a cavity type cylinder housing, a head, a moving body, and at least one grip. The cavity type cylinder housing has a tip for engaging with a touch screen at one end and the head is retractably installed at the other end of the cylinder housing. A moving body disposed within the cylinder housing and coupled to the head slidably moves depending on a retraction operation of the head. At least one grip is installed such that a portion of the grip is protudes outwardly from the cylinder housing depending on a movement direction of the moving body.

A portable communication device and a sliding and rotating hinge apparatus are provided. The device includes a first housing; a second housing, facing the first housing when the device is in a folded state; and a hinge unit. The hinge unit has a first portion attached to the second housing and is configured to slide, together with the second housing, with respect to the first housing to reach a disengaged position. A second portion of the hinge unit automatically rotates once the disengaged position is reached, thereby automatically rotating the second housing around a hinge axis of the hinge unit to open the device to an unfolded state.

Portable communication device and sliding and rotating hinge apparatus thereof

Disclosed is a contact terminal closing device for a portable storage device. The disclosed contact terminal closing device includes: a contact terminal received in a housing; a guide frame; a push sliding knob coupled to the guide frame in such a manner that depending on whether the push sliding knob is manually pushed or not, the push sliding knob locks the contact terminal or releases the contact terminal from the locked state, the push sliding knob being moved in the longitudinal direction of the guide frame to manually retract the contact terminal into the housing or to manually extract the contact terminal from the housing; and one or more shielding members provided on the guide frame to be cooperatively moved depending on the movement of the push sliding knob, the shielding members being adapted to completely shield the contact terminal from the outside.

Contact terminal covering device

A receiver for use in a cellular communication system includes a first amplifying circuit for amplifying a received signal, an attenuating circuit for selectively attenuating the amplified signal in response to a control signal, a first converting circuit for converting the attenuated signal into an intermediate frequency signal, a second amplifying circuit for amplifying the intermediate frequency signal, a limiter for limiting the amplitude of the amplified intermediate frequency signal, a second converting circuit for converting the current of the amplified intermediate frequency signal or the amplitude-limited intermediate frequency signal into a first direct voltage, a determiner for outputting the control signal for attenuating a received signal strength indicator (RSSI) of the amplified signal by a predetermined strength if the first direct voltage is greater than a predetermined reference voltage and for adding a predetermined voltage with the first direct voltage and then for outputting the added voltage as a second direct voltage, and a detector for detecting the RSSI from the second direct voltage.

Receiver for extending the dynamic range of a received signal strength

A frequency-modulation modulator in a cellular wireless telephone for modulating frequency after uniformly and linearly compensating for frequency characteristics to be suitable for each engaged channel in a cellular wireless telephone. Since frequency modulation characteristics are compensated uniformly and linearly according to each one of a plurality of channels, an error due to the frequency distorted modulation can be prevented and the cellular wireless telephone becomes more reliable. The frequency-modulation modulator includes a controller for providing data to assign the channel by sensing a transmitting/receiving channel, and for generating a switch control signal corresponding to each channel, and of a frequency compensator for compensating for frequency characteristics according to each channel by regulating a gain of an input channel by means of the switch control signal from the controller, and of a capacitance converter for converting a given voltage value from the frequency compensator into a capacitance value, and of a resonator for generating a given resonance frequency with the capacitance value of the capacitance converter, and of a voltage controlled oscillator for generating an oscillation frequency to modulate the corresponding frequency based on the resonance frequency.
