Abstract: An elastic electrical contact device and a contact conductor are introduced. The elastic electrical contact device includes two contact conductors. Each contact conductor includes a head and an electrical contact portion integrally connected with each other. The electrical contact portion has a cross section shaped as a curved bend and has a guide groove formed thereon. The electrical contact portion is bilaterally symmetrical along a second central axis, wherein a first central axis and the second central axis are parallel to each other and non-coaxial. The electrical contact portions of the two contact conductors are disposed to have openings thereof face each other and are mutually connected in respective guide grooves, are mutually slidable to extend and retract relative to each other, and are sleeved by an elastic reset member to enable the two contact conductors to be elastically reset when extending and retracting relative to each other.

Abstract: In an authority management method for providing interoperability across different locations and networks, an identity information database and an authority information database are established. Biological image information is obtained from users and registered in the database or an associated database. Biometric image information and an access request of a user are obtained. If there is certain identity information matching the biometric image information of the user in the identity information database, information as to authority and extent of authority are certain identity information queried from the authority information database. The access request is determined to be allowed or not allowed according to the certain authority information. If the access request is to be granted, and allowed in respect of a desired activity, an operation instruction is generated accordingly. A system for administering such method and device applying method are also disclosed.

Abstract: A case structure for card-type electronic product includes an intermediate frame having insertion slots spaced thereon; a lower cover connected to a lower side of the intermediate frame by lower hooking members upward inserted into the insertion slots, and each of the lower hooking members including two spaced latch legs; and an upper cover connected to an upper side of the intermediate frame by upper hooking members downward inserted into the insertion slots corresponding to the lower hooking members, and each of the upper hooking members including two laterally outward extended latch hooks. When the upper and lower covers are assembled to the upper and lower sides of the intermediate frame, the latch hooks of the upper hooking members are abutted on lower edges of the latch legs of the lower hooking members to firmly hold the lower cover to the upper cover in three directions.

Abstract: A method of producing workpiece having irregular cross section by stamping thin plate into thick plate is provided. In the method, a thin plate having a uniform thickness corresponding to that of a thinner area to be formed on the workpiece is used. Multiple stamping heads having different and gradually increased bevel angles are used one by one to stamp one or two sides of the thin plate at a predetermined scrap area, so that a part of the scrap area is gradually compressed and pushed toward a specific area that is to have larger thickness on said workpiece. When the specific area bumps to a predetermined height, a stamping mold is used to downward stamp the bumped area into a predetermined shape. Thereafter, the remained scrap area on the thin plate is removed to obtain the desired workpiece. The method enables largely reduced scrap and manufacturing time and cost in forming a workpiece having irregular cross section.

Abstract: A connector socket includes a main body having a card slot and a guide hole communicable with the card slot, a metal cover having a guide channel at one side opposite to the guide hole and a downward extended stopper opposite to the card slot, a control bar movably received in the guide channel, and a metal lever located between the metal cover and the main body and held to the metal cover with a hooking plate upwardly projecting from a hole in the metal cover. The metal lever has a first downwardly bent end engaged with an inner end of the control bar to move along with the latter, and a second downwardly bent end engaged with the guide hole on the main body. A rear edge of the metal lever has at least one supporting point in contact with the stopper of the metal cover.
