A method of and device for updating a navigation device through communication with a User Equipment (UE). The method includes recognizing at least one of a location and an object as a Point of Interest (POI), based on a user preference set in advance or a user's input; transmitting, to the UE, a request for additional data associated with the location or the object; receiving, from the UE, the additional data associated with the location or the object through the communication; and updating the navigation device using the additional data.
Abstract:
A method and an apparatus for recognizing characters using an image are provided. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.

Abstract:
A method and apparatus are provided for transmitting wireless power to at least one wireless power receiver. The apparatus includes a communication unit that receives power management information from the at least one wireless power receiver, wherein the power management information includes a power capacity of each of the at least one wireless power receiver; and a controller that analyzes the power management information and determines whether an output capacity of the wireless power transmitter is greater than a total sum of the power capacities of the at least one wireless power receiver.
Abstract:
Methods and apparatuses are provided for controlling power transmission in a power transmitter. Voltage information including a minimum voltage, a maximum voltage, and a first voltage, is received from each of a plurality of power receivers. Power is transmitted to the plurality of power receivers based on the voltage information. A respective report about a power reception condition is received from each of the plurality of power receivers while transmitting the power. Each respective report includes a measured voltage at a corresponding power receiver of the plurality of power receivers. A power receiver is selected from among the plurality of power receivers based on the received reports. An amount of the power is adjusted by reducing a difference between a first voltage of the selected power receiver and a measured voltage of the selected power receiver.
Abstract:
A method for providing interaction information, such as, for example, settlement information, by which a device provides the settlement information to a counterpart device, includes displaying an image which relates to an item to be used for performing the interaction, such as, for example, a credit card image of a credit card of a user of the device, on a lock screen of the device, and receiving a touch input from the user with respect to the credit card image. In the method, settlement information which corresponds to the touched credit card image is used for performing a settlement via the device.
Abstract:
A control method of a wireless power transmitter and a wireless power transmitter. The method includes transmitting a first power with a first cycle; transmitting a second power with a second cycle, wherein the second cycle is greater than the first cycle; when a wireless power receiver is placed within a charging area and is detected by the first power, upon detecting the wireless power receiver by the first power, transmitting a third power to drive the wireless power receiver to transmit a search signal to the wireless power transmitter; and when the wireless power receiver is placed within the charging area and is not detected by the first power, using the second power to detect the wireless power receiver and drive the wireless power receiver to transmit the search signal to the wireless power transmitter.
Abstract:
