A method and an electronic device thereof for controlling a user input includes detection of a connection of the electronic device and an external display device. An application selected by a user control is executed and an execute image is provided to the external display device. Whether an event for controlling a user input occurs is detected. When the event for controlling the user input occurs, the user input is processed as an input for the selected application being displayed on the external display device.

Method for controlling user input and electronic device thereof

A polypropylene resin composition, particularly, an olefin-based polypropylene resin composition includes: about 50 to 70% by weight of a high crystalline polypropylene; about 10 to 20% by weight of a reactor made thermoplastic polyolefin (RTPO) polypropylene; about 5 to 20% by weight of an inorganic filler; about 10 to 20% by weight of a rubber elastomer; and about 3% by weight or less of a slip agent, based on the total weight of the composition. The composition provides excellent physical properties such as high strength and impact resistance, and thus superior resistance to damage, and shows low gloss characteristics and excellent fluidity. The polypropylene resin composition is used as interior and exterior materials for vehicles.

A charge relay enhancer used in relaying a charge produced in a solar cell to a charger, and a solar cell system including the charge relay enhancer. The charge relay enhancer includes: a charge induction and pumping device inducing a charge by using a power voltage from among two power voltages of different polarities selected in response to a control signal, and pumping the induced charge; and a charge pathway selecting device relaying the charge input to an input terminal via two input/output terminals, to the charge induction and pumping device, receiving the charge pumped by the charge induction and pumping device via the two input/output terminals, and outputting the charge to an output terminal. Accordingly, as charges produced in a solar cell may be relayed to a charging device as much as possible, efficiency of relaying charges produced in the solar cell to the charging device may be maximized.

Electrical charge relay enhancer and solar cell system including the enhancer

Disclosed are a polyolefin-based resin composition having excellent scratch resistance and low glossiness, a preparation method thereof, and automobile interior and exterior materials fabricated therefrom. The polyolefin-based resin composition comprises about 56 to 97% by weight of a polypropylene block copolymer resin, about 1 to 9% by weight of a thermoplastic elastomer rubber, about 1 to 30% by weight of an inorganic filler, and about 1 to 5% by weight of a fluoroacrylamide-based copolymer based on a total weight of the composition.

A method of changing a display mode in a car navigation system, the method including: acquiring distance information from a current vehicle location to a guide point; and gradually changing the display mode into any one of a two-dimensional display mode and a three-dimensional display mode based on the distance information.

Method for changing dynamic display mode and apparatus thereof in car navigation system

A method of controlling signal power level and a Bluetooth device for performing the same are provided. The method for controlling a power level of a signal to be transmitted to a remote Bluetooth device via a Bluetooth link, comprises: a local Bluetooth device for receiving a first signal from a remote Bluetooth device for determining if the remote Bluetooth device is providing a request to control a power level of the first signal to be transmitted; determining if a power level of a second signal is to be controlled based on a condition of a wireless link when the remote Bluetooth device does not provide the request to control the power level of the first signal; and controlling the power level of the second signal to be transmitted to the remote Bluetooth device.

Method of controlling signal power level and a Bluetooth device for performing the same

A method for compensating a motion of a moving image after estimating said motion is provided. In the method, a triangle-patch wireframe model is formed on a present frame of the moving image, and the triangle-patch wireframe model contains apexes. The motion vectors between the apexes of the triangle-patch wireframe model and corresponding points on a previous frame of the moving image is determined. The triangle-patch wireframe model on the present frame is transformed to form a transformed triangle-patch wireframe model on the previous frame by using the motion vectors such that the corresponding points respectively relate to secondary apexes of the transformed triangle-patch wireframe model. A first pixel value of a first pixel located at a predetermined position within the triangle-patch wireframe model of the present frame is replaced with a replacement pixel value of a second pixel located at a corresponding position within the triangle-patch wireframe model in the previous frame. Then, a new image is reconstructed using the replacement pixel value.
