Abstract: A torsion beam type suspension and a forming method of a torsion beam are disclosed. In the torsion beam type suspension comprising a pair of left and right trailing arms connected to each other through a torsion beam, front ends of the trailing arms being used to mount a vehicle body by using joints, the torsion beam is obtained by forming an overall length of a pipe having a certain wall thickness by using a pressure forming process. In this case, end sections defined at both end portions of the torsion beam have a cross-sectional shape of a hollow oval, a center section defined at a center portion of the torsion beam has a cross-sectional shape of a hollow open loop, and middle sections defined between the center portion and both the end portions of the torsion beam have a cross-sectional shape of a hollow open loop. The loop of the middle sections defines an inner space larger than that defined by the loop of the center section.

Abstract: A method, a system and a mobile terminal for providing data services, whereby specific data services according to a zone of a precinct wireless network are conveniently provided to mobile terminal subscribers in the precinct wireless network, while preventing the maintenance of an unnecessary connection of the terminal to the precinct wireless network. When a mobile terminal enters the precinct wireless network, at least one application program corresponding to a predetermined data service function of the mobile terminal is automatically executed, and thereafter when the terminal exits the precinct wireless network, the application program is automatically terminated. In addition, the terminal opens a data channel connection with the precinct wireless network only when the data service is currently executed in it.

Abstract: A method and apparatus to manage call control in a Computer Telephone Interface (CTI) system includes: a computer terminal to generate a call control message including call control identification information using a CTI application program in response to a call control command from a user, and transmitting the generated call control message; wireless terminals to perform call control upon receipt of the call control message; and an exchange to receive the call control message from the computer terminal, and to maintain the call control message generated by the computer terminal unchanged and to interface it to a corresponding one of the wireless terminals in response to the call control identification information being detected from the received call control message.

Abstract: A toy type learning device and a method of controlling the toy type learning device are disclosed. A toy type input unit outputs a contents request signal in response to a user's key operation. A remote control unit converts the contents request signal into a wireless signal and outputs the wireless signal to a processing unit having a plurality of contents to request a corresponding content. Thus, the toy type learning device and a controlling method of the toy type learning device may extract the corresponding contents in response to the user's key operation and control an output of a multimedia, so that the toy type learning device may be used as a learning assistant for infants or children.

Abstract: A flat panel display apparatus includes a main plate, an organic light emitting element, a protecting layer and an attachable-detachable layer. The organic light emitting element includes a first electrode, a second electrode corresponding to the first electrode, and an organic light emitting layer disposed between the first and second electrodes to generate a light based on a current that flows between the first and second electrodes through the organic light emitting layer. The organic light emitting element is on the main plate. The protecting layer is on the organic light emitting element to protect the orgnaic light emitting element. The attachable-detachable layer is on the protecting layer. Therefore, an image display quality is improved, and a manufacturing cost is decreased.

Abstract: The present invention provides ?-hydroxy benzeneacetic acid derivatives of the formula as defined in the specification which is a precursor indispensable for synthesis of compounds having two 5-membered lactone rings fused to central cyclohexa-1,4-diene nucleus, and a process of easily preparing the same. According to the preparation process of the present invention, the ?-hydroxy benzeneacetic acid derivative can be readily prepared at high purity and yield without using toxic materials or producing toxic by-products. Some novel compounds, synthesized by using such a x-hydroxy benzeneacetic acid derivative, have excellent fastness properties, dye fixing rate and leveling property to general synthetic fiber materials such as polyester fibers and their blends with other fibers, especially to micro fibers, and also can be used as a coloring agent for plastic resins, color tonors, color filters, etc.

Abstract: A method and a system of managing conflicts between context-aware applications by use of semantics of abstract service for group context information management. The method includes detecting and resolving a conflict between context-aware applications; upon receiving a service request from an application, analyzing a semantic of the requested service; and registering the semantic into a data structure. A determination is made whether a conflict between service actions occurs in the data structure and when the conflict occurs, removing the semantics of the conflicting service actions from the data structure. The conflict between the service actions arises when actions of the valid applications according to the user policies contradict the same context information in the data structure. After removing the semantics of the service actions from the data structure, a resolution policy for the conflict is generated, and a new service is requested according to the resolution policy.

The loop of the middle sections defines an inner space larger than that defined by the loop of the center section.
