Patent application number | Description | Published |
20110003568 | APPARATUS AND METHOD FOR SEARCHING RADIO CHANNEL IN A PORTABLE TERMINAL - An apparatus and method for searching for an improved radio broadcast in a portable terminal are provided. The apparatus includes a radio function performance unit. If an input for a radio broadcast channel search is detected while listening to a radio broadcast, the radio function performance unit changes from an original previously listened radio broadcast to a radio broadcast corresponding to the detected input. If the input for the radio broadcast channel search is released, the radio broadcast channel is restored to the original previously listened radio broadcast channel. | 01-06-2011 |
20120109779 | METHOD AND SYSTEM FOR SHARING DIGITAL CONTENT - A method and system for sharing digital content are provided. The method includes creating, by a first user, a purchase request message containing a content ID of digital content to be purchased, and transmitting the purchase request message to a content providing server, transmitting, by the content providing server, requested content to the first user, and transmitting content meta data containing a user ID of the first user and the content ID to an integrated management server, storing, the first user, the received content, and examining, by the integrated management server that manages content lists for individual users, the content meta data, adding the purchased content to an integrated content list of the first user, and displaying the integrated content list. | 05-03-2012 |
20120176230 | METHOD OF TURNING AN ALARM OFF AND MOBILE DEVICE ADAPTED THERETO - An alarm turning off method and a mobile device adapted to the method are provided. The method includes reproducing a preset alarm audio sound and outputting a preset beat at a preset alarm time, determining whether the mobile device receives an input beat, when the mobile device has received the input beat, muting the reproduced alarm audio sound, determining whether the preset beat is identical to the input beat in a state where the alarm audio sound is muted, and turning off the alarm when the number of occurrences where the preset beat matches the input beat is a preset number in a state where the alarm audio sound is muted. | 07-12-2012 |
20120316873 | METHOD OF PROVIDING INFORMATION AND MOBILE TELECOMMUNICATION TERMINAL THEREOF - A method of providing information of a mobile communication terminal, and a mobile communication terminal for performing the method, are provided. The method includes determining whether a search command event has been generated during a call with a counterpart terminal, converting a voice signal received from a microphone into a text when the generation of search command event is determined to have been generated, identifying information matching the text in a memory, and sending the information to the counterpart terminal. | 12-13-2012 |
20130013932 | SECURITY MANAGEMENT SYSTEM AND METHOD FOR LOCATION-BASED MOBILE DEVICE - A method and a system of managing information security for a mobile device in a restricted area based on location information regarding the mobile device are provided. The method includes receiving, by the mobile device, a request for the execution of an application program in a restricted area from a server managing the restricted area, executing, by the mobile device, the application program requested for execution when the program was set to be executable according to a security policy set to the restricted area, encrypting, by the mobile device, a file, created according to the execution of the application program, based on location information regarding the mobile device, and storing the encrypted file. | 01-10-2013 |
20140139173 | IMAGE FORMING APPARATUS, CONTROL METHOD FOR THE SAME, AND MOTOR STATE DETECTOR - An image forming apparatus, a control method for the same, and a motor state detector are provided. An aspect is to detect out-of-step of a motor using only an electric circuit configuration without additional mechanical devices, such as an encoder, a light-emitting device, and a light-receiving device, and to predict and prevent out-of-step of the motor. To this end, the image forming apparatus includes a motor state detector that acquires a current detection signal by detecting phase current of a motor and that generates an output signal in which a duty ratio in a current chopping section of the current detection signal is involved, and a controller that judges a normal state, out-of-step entry, and an out-of-step state of the motor based on the output signal of the motor state detector. | 05-22-2014 |
20140333250 | IMAGE FORMING APPARATUS, MOTOR CONTROL APPARATUS, AND METHOD OF CONTROLLING A MOTOR - An image forming apparatus may include an engine portion used to perform an image forming job, a step motor configured to start the engine portion, a driver including a resistor that measures current that flows to a coil of the step motor and is configured to provide a predetermined constant current to the step motor, and a drive controller configured to measure a load level of the step motor based on a voltage value of the resistor and to control the driver to provide the constant current that corresponds to the measured load level. | 11-13-2014 |
20150097503 | IMAGE FORMING APPARATUS, MOTOR CONTROL APPARATUS, AND METHOD OF CONTROLLING MOTOR - An image forming apparatus includes an engine portion configured to perform image forming, a direct current (DC) motor configured to mechanically operate the engine portion, a driver including a resistor to measure current that flows to the DC motor according to the measured current and configured to provide a predetermined voltage to the DC motor, and a drive controller configured to measure a driving speed of the DC motor based on a voltage value of the resistor and to control the driver to provide a voltage that corresponds to the measured driving speed to the driver. | 04-09-2015 |
