An apparatus including a touch screen is provided. The apparatus includes the touch screen to display a first window for executing a first application and a second window for executing a second application, and a controller to detect whether a display change event for changing a screen display occurs in at least one of the first window and the second window, and to analyze the display change event in order to rotate a display direction of the at least one of the first window and the second window in which the display change event occurs.

A method and an apparatus for transmitting data in a wireless communication network are provided. A base station having information of an idle mode user equipment transmits a connecting operation mode to the user equipment when the idle mode user equipment is connected to the base station. The user equipment transmits a small amount of data together with a connection request completion message to the base station. The base station transmits, over a network, the data received from the user equipment, without being interlinked with a mobility management entity, and the user equipment returns back to an idle operation mode after data transmission. Thus, the overhead required to support signaling of the base station for acquiring context information of the user equipment can be reduced in order to provide the user equipment with an efficient data transmission environment.

The preferred embodiment of the invention includes a casing that encloses an extension cord system. The casing has slots that allow access to retractable electrical power cords. The cord system comprises a plurality of spring-loaded and ratcheted spools containing electrical power cords. The preferred embodiment of the method includes steps for preventing the entanglement of power cords and maintaining a clutter-free and efficient work environment.

According to this invention, bookbinding data containing pages created by respective applications can be constructed regardless of the type of application. Even when one or more desired pages contained in bookbinding data are selected, image editing is designated, but a non-image page exists in the selected pages, the non-image page can be excluded from editing targets, and the process can shift to image editing. For this purpose, when a plurality of pages are selected and image editing is designated, whether each selected page is an editable image page is determined. An editable page is temporarily stored. After all the selected pages are determined, an image editing application is activated to edit stored editable image pages.

This invention presents a noise cancellation device for improved personal face-to-face and radio communications in high noise environments. The device comprises speech acquisition components, an audio signal processing module, a loudspeaker, and a radio interface. With the noise cancellation device, the signal-to-noise ratio can be improved by as much as 30 dB.

Electrostatic system is for optimal charging of aerosols and particulates. In order to improve their collection, the system uses a combination of DC field and AC fields produced by multiple AC electrodes. The system minimizes the size and power consumption of the device, as well as increasing the collection efficiency.

A multiply thin paper sheet having a press-to-bond structure is disclosed, including a first thin paper layer having a first stacking surface and at least one second thin paper layer having a second stacking surface. The first and second stacking surfaces are partially overlapped with each other to define a stacking zone provided between the first thin paper layer and the second thin paper layer. After the stacking zone is subjected to a rolling operation by a rolling pressure, a plurality of first pressed sections are formed on the first thin paper layer, having a predetermined height extended according to a given direction, and a plurality of second pressed sections are formed on the second thin paper layer according to the given direction and respectively corresponding to the first pressed sections of the first thin paper layer. At least one portion of each first pressed section and the respective corresponding second pressed section are bonded and formed as a pressed and bonded site, such that the first thin paper layer and second thin paper layer can be pressed, bonded and patterned simultaneously.
