Abstract: A hinge assembly includes a positioning module, a connecting module and a rotating module. The positioning module includes a sleeve. The connecting module includes a pivot tube and an shaft. The pivot tube is rotatably attached to the sleeve. The shaft is slidably and rotatably received in the pivot tube. The rotating module is rotatably attached to one end of the shaft.

Abstract: An exemplary chip card holder (100) used in a portable electronic device for holding a chip card (50) is provided. The chip card holder includes a housing member (10), a holding member (20), and a driving member (30). The holding member is fixed to the housing member for receiving and holding the chip card. The driving member is movable relative to the housing member and the holding member for moving the chip card from either of a released position and a holding position to the other of the holding position and released position.

Abstract: A service library framework that provides a common software interface for low-level system management software modules that provides system administration processing and interfaces with remote computers that execute various types of operating systems. Service library modules are created for each operating system to be managed by a system administration management system. High-level system management applications are only required to have interfaces to a common, generic system request and response interface provided by the service library. The operating system specific service library modules translate requests into operating system specific requests and translate operating system responses into generic messages to be returned to the high-level system.
