The hinge unit is slidable on the main body together with the folder. The mode-switching of the portable being provided according to the sliding position of the hinge unit.
Abstract:
In a method of wirelessly transmitting an audio and/or video input signal having a standard definition (SD), the input signal is converted to a signal having a high definition (HD) and noise is removed from the converted signal. High definition encoding is performed to the noise-free signal and the encoded signal is wirelessly transmitted. Accordingly, image deterioration can be reduced by eliminating the noise before encoding the input signal. In addition, the HD encoding is performed instead of the SD encoding to reduce image degradation.
Abstract:
An image forming apparatus is configured to reduce a velocity fluctuation of a rotating body by reducing the AC velocity component of the rotating body. The image forming apparatus may include an image bearing body with a surface on which a toner image is formed; a driving motor configured to drive the image bearing body according to an input signal; and a controller configured to control the driving motor to output a motor output velocity at a period equal to that of an AC velocity component of the image bearing body. A velocity control method for the rotating body includes sampling a continuous motor input signal at a period equal to that of an AC velocity component of a rotating velocity of the rotating body. The sampled signal is transmitted to a driving motor that drives the rotating body, which is driven based upon the discrete motor input signal.
Abstract:
Disclosed are an electrochemical biosensor which comprises a production lot information identification portion, on which information is recorded in a magnetization mark, and a measuring device which can automatically identify the production lot information of the biosensor with the insertion of the electrochemical biosensor into the measuring device. The electrochemical biosensor and the measuring device thereof can record production lot information in the form of magnetization marks on an electrochemical biosensor strip and read the information as digital signals through a magnetoresistance sensor device, which can be mounted on the surface of a circuit board using Surface Mounted Technology (SMT). Without the need for a high-priced filter or a complicated calculation system, the magnetic detector system has a simple construction and realizes economic efficiency in the construction of the measuring device. Also, the measuring device automatically identifies the production lot information recorded on the biosensor, so that inconvenience and the frequency of errors, which occur when a user personally inputs the production lot information, can be reduced, with the result that the measured values can be conveniently and accurately acquired.

A method of matching game users for a game in an electronic device, the method including: displaying a user interface screen to receive, from a user, a selection of an option for starting the game; and creating a match by searching a network and/or a subnet for one or more game participants in response to receiving a selection of an option, via the user interface screen, to match a plurality of users to play the game. Accordingly, it is possible to more rapidly create a match between a plurality of game participants.
Abstract:
The present invention describes a semiconductor device that generates internal voltages having different levels using an external voltage. The semiconductor device includes a plurality of asynchronous internal voltage generating circuits that share an external voltage source and generate internal voltages having different levels from one another. The plurality of asynchronous internal voltage generating circuits maintain the levels of the internal voltages at target levels by using the external voltage at different time points, respectively. The semiconductor device minimizes noise in the external voltage according to the use of the internal voltages.
