20100032409 | FABRICATING A GRAPHENE NANO-DEVICE - Nanoscale graphene structure fabrication techniques are provided. An oxide nanowire useful as a mask is formed on a graphene layer and then ion beam etching is performed. A nanoscale graphene structure is fabricated by removing a remaining oxide nanowire after the ion beam etching. | 02-11-2010 |
20100060428 | RFID DEVICE AND METHODS FOR CONTROLLING POWER SUPPLY ACCORDING TO CONNECTION WITH HOST AND OPERATION MODE - A radio frequency identification (RFID) device and method for controlling power supply are provided. The RFID device controls power supply to its elements based on its connection with a host and its operation mode, thereby reducing power consumption. | 03-11-2010 |
20150033165 | DEVICE AND METHOD FOR CONTROLLING OBJECT ON SCREEN - A method for controlling an object on an electronic device having a touch screen is provided. The method includes displaying at least one object on the touch screen, receiving a first input on the touch screen, selecting an object from the at least one object, based on the first input, receiving a second input on an area other than the object in the touch screen, and modifying the selected object, based on the second input. An electronic device having a touch screen includes a touch screen configured to display at least one object on the touch screen, and a controller configured to receive a first input on the touch screen, select an object from the at least one object, based on the first input, receive a second input on an area other than the object in the touch screen, and control the selected object, based on the second input. | 01-29-2015 |
20160042723 | ELECTRONIC DEVICE AND METHOD OF CONTROLLING DISPLAY THEREOF - An electronic device and a method of controlling a display of the electronic device are provided. The method includes arranging a first image and a second image vertically on different layers; measuring a tilt of the electronic device; and displaying at least one of the first image and second image by controlling transparency of the first image based on the measured tilt. | 02-11-2016 |
