Abstract:
A flexible device includes a flexible body and a plurality of piezoelectric materials arranged on the flexible body that deform in response to drive signals causing deformation of the flexible body of the flexible device.
Abstract:
A portable terminal provides a fingerprint-based shortcut key to realize both security and one touch convenience. The portable terminal includes a fingerprint sensor for recognizing user's fingerprint, a memory for storing fingerprint data, and a controller for mapping and storing first fingerprint data inputted through the fingerprint sensor and a function of the portable terminal in the memory. Upon input of second fingerprint data through the fingerprint sensor, there is a comparison of the first fingerprint data with the second fingerprint data, and performing the function mapped to the first fingerprint data when the first fingerprint data is identical to the second fingerprint data. The portable terminal may perform the authentication and provide the result to another portable terminal, or an authentication server can perform the comparison.
Abstract:
An operation method of an electronic device that is operable with a dummy device is provided. The method includes operating the dummy device through a physical coupling to the electronic device, establishing, by the electronic device, a wireless connection with the dummy device if a call is received by the electronic device, and operating the electronic device with the dummy device through the wireless connection.

Abstract:
A rinse solution includes a surfactant and deionized water. The surfactant includes a compound having a branched structure, the compound having a branched structure including a hydrophobic group-containing main chain and a plurality of side chains that are branched from the main chain and have at least one hydrophilic functional group. A method of fabricating an integrated circuit device includes forming a photoresist pattern, followed by applying the rinse solution onto the photoresist pattern.
Abstract:
A photoresist polymer comprising a first repeating unit including a halogen donor group and a second repeating unit including a protecting group connected by a sulfide bond.
Abstract:
A method and apparatus for controlling an operation mode in a mobile terminal provides the mobile terminal to determine whether a predetermined time has elapsed, after a lapse of which it enters a first power-saving mode, and drive a camera module if the predetermined time has elapsed. Meanwhile, the mobile terminal determines whether a predetermined subject is recognized by the camera module, and then delays changing to the first power-saving mode if the predetermined subject is recognized, and enters the first power-saving mode if the predetermined subject is not recognized.
Abstract:
A method for providing a graphic keyboard in a touch-screen terminal is provided. In the method, a keyboard is divided into a plurality of key group regions. A key display aspect of each key group region is determined. Shapes or layouts of keys of each key group region are controlled depending on the key display aspect. Another method involves determining a characteristic of a contact area of at least one touch on at least one graphic key of a displayed keyboard. Shape or layout of the at least one key is controlled based on the determined characteristic.
