Patent application numberDescriptionPublished
20090185437CLOCK-BASED DATA STORAGE DEVICE, DUAL PULSE GENERATION DEVICE, AND DATA STORAGE DEVICE - Disclosed is a clock-based data storage device, which includes a dual pulse generating device and a data starge device having two dynamic nodes for prior chargement/dischargement. The clock-based data storage device includes a dual pulse generating unit which delays a clock signal and then outputs a first clock signal corresponding to inversion of a clock signal and a second clock signal corresponding to the clock signal by using the delayed clock signal when the clock signal shifts, a pull-up wait for outputting a pull-up output signal to an output port, based on the first clock signal outputted from the dual pulse generating unit and an input data signal which has beeb inputted, a pull-down unit for outputting a pull-down output signal to the output port, based on the second clock signal outputted from the dual pulse generating unit and the input data signal inputted which has been inputted, and a latch unit which is disposed between the pull-up and pull-down units, and the output port so as to store at least one output signal outputted f roars the pull-down unit as well as the pull-down unit.07-23-2009

20100035671MOBILE COMMUNICATION TERMINAL CASE AND METHOD OF MANUFACTURING THE SAME - There is provided a mobile communication terminal case including: a case body of a mobile communication terminal having a first surface and a second surface opposite to the first surface, and a via hole formed through the first surface and the second surface; a conductive pattern provided on the first surface of the case body; a carrier film provided on the first surface of the case body to cover the conductive pattern; and conductive epoxy filling the via hole and having one end thereof in contact with the conductive pattern.02-11-2010
20100220028ANTENNA-EMBEDED CASE FOR MOBILE COMMUNICATIONS TERMINAL, METHOD OF MANUFACTURING THE SAME, AND MOBILE COMMUNICATIONS TERMINAL - A method of manufacturing an antenna-embedded case for a mobile communications terminal includes providing an antenna pattern, forming a first injection-molded member covering one surface of the antenna pattern, and disposing the first injection-molded member, provided with the antenna pattern on one surface thereof, in a second mold with the antenna pattern disposed in a space inside the second mold, and injection-molding a second injection-molded member covering the other surface of the antenna pattern to embed the antenna pattern between the first injection-molded member and the second injection-molded member.09-02-2010
20100271272ANTENNA PATTERN FRAME, METHOD AND MOLD FOR MANUFACTURING THE SAME, AND ELECTRONIC DEVICE - An antenna pattern frame according to an aspect of the invention may include: a radiator having an antenna pattern portion transmitting and receiving a signal; a ground portion extending from the antenna pattern portion; a connection portion connecting the antenna pattern portion and the ground portion to be arranged in different planes; and a radiator frame manufactured by injection molding on the radiator so that the antenna pattern portion may be provided on one side of the radiator frame and the connection terminal portion may be provided on the other side thereof, the radiator frame allowing the antenna pattern portion to be embedded in the electronic device case.10-28-2010
20100271283ANTENNA PATTERN FRAME AND METHOD OF MANUFACTURING THE SAME - An antenna pattern frame according to an aspect of the invention may include: a radiator having an antenna pattern portion transmitting and receiving a signal and a connection terminal portion allowing the signal to be transmitted to and received from a circuit board of an electronic device; a connection portion partially forming the radiator and connecting the antenna pattern portion and the connection terminal portion to be arranged in different planes; a radiator frame manufactured by injection molding on the radiator so that the antenna pattern portion may be provided on one side of the radiator frame and the connection terminal portion may be provided on the other side thereof, while the antenna pattern portion is embedded in the electronic device case; and a contact surface extension provided on the radiator to prevent the radiator from being loosened from the radiator frame during injection molding of the radiator frame, and increasing a contact area with respect to the radiator frame.10-28-2010

20100322456Speaker device for mobile terminal - A speaker device for a mobile terminal enlarges resonance space of a speaker while decreasing a size of the mobile terminal. The speaker device for a mobile terminal includes at least one speaker installed within a main body of the mobile terminal and a speaker bracket installed at one surface of an electronic circuit board mounted within the main body. In addition, the speaker bracket fixes the at least one speaker in place and has housing space to enclose the at least one speaker therein. At least one resonance groove is formed in a portion enclosed by the speaker bracket in one surface of the electronic circuit board. Because resonance space can be enlarged without increasing a size of the speaker bracket, an entire thickness of the mobile terminal can be reduced and thus a size and thickness of the mobile terminal can be decreased.12-23-2010
20110085015Apparatus and method for operating plural cameras embedded in mobile device - A mobile device includes an apparatus for operating two or more cameras embedded in a mobile device. When one of the cameras is enabled, the apparatus controls the flow of signals by preventing a signal in connection with the enabled camera from flowing toward other disabled cameras. This can minimize EMI that may be caused by such a signal.04-14-2011
