Abstract: A task scheduling method and apparatus are provided to execute periodic tasks together with an aperiodic real-time task in a single system, to perform scheduling while satisfying a precedence relation between periodic tasks, and to perform scheduling so that an aperiodic real-time task may be efficiently executed for a residual time left after scheduling of the periodic tasks. Additionally, a component scheduling method and apparatus in robot software are provided.

Abstract: The present invention is directed to an automatic hinge module for a cellular phone, which is capable of automatically opening the cellular phone in a one-touch manner. The automatic hinge module of the present invention automatically opens a cellular phone by simply pressing a button. When the button is pressed, a housing coupled to a folder portion of the cellular phone is rotated by an elastic restoring force of a compressed torsion spring, thereby opening the cellular phone.

Abstract: Provided is an apparatus and method for automated testing of a software program. More particularly, provided is an apparatus and method for automated testing of a software program of which a source code is frequently changed. An aspect of the present invention provides an apparatus and method for automated testing of a software program that may automatically perform testing with respect to a source code file changed within a software program based on a correlation between a plurality of test objects for testing of the software program.

Abstract: A testing tool for verifying a reliability of robot software components is provided, and more particularly, a simulation-based interface testing automation system and method that may automatically perform a test for functions and performance of an interface with respect to robot software components are provided. Thus, it is possible to efficiently perform a test for an interface of robot software components. In particular, it is possible to automatically generate test cases required for testing, to perform a test in various languages, and to perform a test suitable for a robot.

Abstract: Disclosed herein is an apparatus for opening and closing a portable terminal. The apparatus includes a second cam, which has an upper rib to be latched with the upper portion of the housing and a lower rib to be latched with the bottom of the housing, thereby providing structural stability. In addition, frictional wear and noise can be suppressed while the second cam moves, thereby improving the service life and reliability of the device.

Abstract: Disclosed herein is a slide-up opening and closing apparatus for a communications terminal. The apparatus includes a slider unit, a slider assembly and an angular positioning member in order to open a slider body with respect to a main body. With the apparatus, the slider body can be opened with a desired inclination against the main body and after a certain degree of opening, automatically complete its opening operation without any further force or action, thereby providing a convenient use. In addition, the slider body can be opened with freedom without interference by the main body. Further, when the slider body is opened, most of the top face of the main body can be exposed, thereby providing a convenience of use.

Abstract: Disclosed is a display tilting mechanism for a communication terminal, in which a display is rotatably connected to a supporter hingedly pivoting on a main body of the communication terminal. The mechanism includes a fixing unit fixedly installed in the supporter. A rotating unit is connected with the display and rotatably installed relative to the fixing unit. A supporting unit is connected with the fixing unit in such a way that the rotating unit is not released when it rotates on the fixing unit. A retaining unit is provided for holding the rotating unit in place at the initial state and rotated state thereof when rotated on the fixing unit. Thus, when watching a movie or the like, the image can be display in a normal orientation.

Abstract: Disclosed is a slider mechanism for slidably opening and closing a portable communication terminal. The slider mechanism includes a first plate and a second plate slidably combined with the first plate. The second plate has a cam profile formed along siding direction. A resilience unit is mounted on the first plate to exert resilient force perpendicularly to moving direction of the second plate. A roller is rotatably attached to an end of the resilience unit. The roller runs along the cam profile while the portable terminal opens or closes. Formed at a desired position of the cam profile is a depression on which the roller rests to hold the terminal in place at closed or opened state, or at any other desired position.

Abstract: Disclosed is a hinge mechanism of portable phone having an advanced configuration, which can perform the opening operation and the rotating operation of a phone cover. The hinge mechanism comprises a housing to connect a phone body and a phone cover, which has a rotary chamber and a hinge chamber, a hinge part to open and to close he phone cover, which is disposed in the hinge chamber, and a rotary part to rotate the phone cover, which is disposed in the rotary chamber. A user can play a game or watch a motion picture using the portable phone while looking at the liquid crystal display of the phone cover, because the phone cover can be rotated.

Abstract: Disclosed hinge assemblies and portable terminals having the same. According to a first embodiment of the present invention, a hinge assembly, a first member is fixed to a side of one article so as to support the one article to horizontally rotate with respect to the other article. A second member is fixed to a side of the other article and engaged with the first member in order to support the other article so that the one article can rotate with respect to the other article. A third member provides the second member with elasticity in order for the first member is tightly engaged with the second member.

Abstract: Disclosed is a hinge device of a portable wireless terminal. The portable wireless terminal includes a first housing, a second housing rotatably coupled to the first housing in such a manner that the second housing moves away from the first housing or approaches the first housing according to a rotational movement thereof, a first hinge axis extending parallel to an upper surface of the first housing, and a second hinge axis extending perpendicular to the upper surface of the first housing and providing a rotational center for the first hinge axis. The first and second hinge axes act as rotational axes of the second housing when the second housing rotates with respect to the first housing.
