Abstract: A surface contact card holder includes a main body defining an entrance, a tray for receiving a surface contact card, and a cover attached to an end of the tray and releasably received in the entrance. The tray is slidably received in the main body through the entrance. The cover includes an operation board comprising elastic material. The tray has a supporting portion protruding from the end with the cover attached. When the operation board is pressed towards the tray, a portion of the operation board deforms to elastically resist the supporting portion, thus a free end of the operation board is raised up around the supporting portion to pivot away from the entrance.

Abstract: A portable electronic device includes a housing defining an opening, a string of a pendant, and a pendant attachment device. The pendant attachment device includes a fixing block, an attachment element rotatably and movably fixed in the compartment, a fixing plate fixed to the housing and an elastic element. The fixing block defines a compartment. The attachment element includes a main body defining a fixing hole, the string is threaded through the fixing hole. In a first state, the elastic element exerts an elastic force on the attachment element, causing the attachment element being latched with the latching block with the fixing hole is located in the opening. In a second state, the elastic element drives the attachment element to move away from the fixing plate, thereby making the fixing hole stick out of the opening.

Abstract: A surface contact card holder includes a housing, a tray and two elastic members positioned between the tray and the housing. The housing includes a support plate and defines an opening. The support plate defines a through hole. The tray is slidable and receivable in the housing from the opening and the tray is configured for carrying a surface contact card therein. The tray includes a tray body and a cantilever arm extending from the tray body. The cantilever arm includes a protruding portion releasbly latched in the through hole. When the protruding portion is pressed to release the tray, the tray is automatically slid out of the opening under the elastic force of the elastic members to allow insertion and removal of the surface contact card from the housing.

Abstract: A fastening assembly includes a fastening block, a release element, and at least one elastic element. The fastening block includes a sliding groove and a stopper portion defined on the sliding groove. The release element includes a pressing portion defining a rope hole formed therein and a stopper column protruding from the pressing portion towards the stopper portion of the fastening block. The end of the stopper column is releasably locked to the stopper portion. The elastic element resists against the fastening block and the pressing portion. When the pressing portion is pressed towards the fastening block, the end of the stopper column moves and gets around of the stopper portion; when the pressing of the pressing portion is released, the elastic element releases elastic expansion to push the pressing portion away from the fastening block.

Abstract: A sliding key module includes a main body, two opposite hooks projecting from the main body and a sliding key. Each hook includes a latch and a guiding portion connecting the latch and the main body. The latches, the guiding portions and the main body cooperatively define a sliding channel. The sliding key includes a first sliding track slidably mounted in the sliding channel. The first sliding track is pressed to mount in the sliding channel through the gap between the latches.

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 a 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: A rotatable connecting mechanism (100) includes a cover (10), a base (30), a toothed element (20) and an elastic element (24). The cover is rotatably mounted on the base (30). The toothed element (20) on a surface of the cover (10) facing to the base (30). The toothed element (20) defining a plurality of toothed grooves (222) around a peripheral wall thereof. The elastic element (24) having an engaging portion (2422) formed thereon and configured on a surface of the base (30) facing to the cover (10). The engaging portion (2422) rotatably engages 5 the plurality of toothed grooves (222).

Abstract: An improved MiniPCI connector structure includes a mini area bus connector and a set of plate type antenna connector. The bus connector comprises an upper unit and a lower unit buckling to each other. The upper unit has a plurality of contacting terminals within, and the adjacent sides of contacting terminals protrude out of the opening of the upper unit to form adapting slot and plug; the flange of the upper unit has two buckling portions, and the lower unit has corresponding adapting slot and corresponding buckling portion corresponding to the contacting terminals and the buckling portions at the flange of the upper unit. Thus, the interne card can be adapted into the adapting slot of the upper unit and the buckling of the buckling portion and the corresponding buckling portion enables the upper unit joining with the lower unit as a mini area bus connector and a set of plate type antenna connector positioning on the circuit board.

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.
