A tamper resistant enclosure for protecting an electronic device containing sensitive information (e.g. an electronic cryptographic card), is provided. The enclosure includes an external cover and an internal cover. Four screws (one at each corner) secure the internal cover to the device and the external cover by means of standoffs. A washer is interposed between the device and the standoff. The device has a dielectric substrate with a metal pad around each hole for ensuring the electrical conne...

An electric resonance element includes an electric resonator comprising a coil wound around magnetic materials and a capacitor. The electric resonance element is housed in a vessel made of non-magnetic materials. A detection apparatus for detecting the electric resonance element comprises a transmitter for transmitting an electromagnetic wave and a receiver for detecting the echo wave transmitted from the electric resonance element. A moving vehicle is controlled using a system which comprises t...

A device for indicating a multi-position state and having one or more sensors, one or more bi-stable, magnetic switches, and a control unit. The switches are provided with an electromagnet arranged in connection with each individual switch thereby enabling the switches to be switched between two or more indicating positions by sending an electric pulse through the electromagnet. The sensors are connected to the control unit, which is in turn connected to the switches. The sensors are arranged to...

A printed circuit board connector engagement apparatus includes a four-bar linkage capable of coupling to an electronics system housing and is configured to accept and enable a printed circuit board to travel in a first direction until a connector on the printed circuit board and a corresponding connector coupled to the housing are aligned. The four-bar linkage further enables the printed circuit board to travel essentially orthogonal to the first direction to engage the printed circuit board an...

A packaging structure of an electronic card includes a metal cover, a plastic frame and a printed circuit board. The metal cover is produced by providing a metal plate having a central portion and an edge portion and performing a draft operation on the metal plate such that the edge portion is vertical to the central portion. The plastic frame has a first surface combined with the metal cover. The printed circuit board is combined with a second surface of the plastic frame.

A universal serial bus hub (100, 700) includes a housing (110) having a top portion (111), a bottom portion (211) opposite the top portion, a first side (112) between the top portion and the bottom portion, and a second side (113) between the top portion and the bottom portion. The universal serial bus hub further includes a first universal serial bus port (120) at the top portion and a second universal serial bus port (210) at the second side.

An information-processing device comprises at least one crossbar-board; a plurality of back panels detachably connected electrically and mechanically to different sides of the crossbar-board; and at least one motherboard detachably connected electrically and mechanically to each of the back panels. The crossbar-board has a switching element mounted thereon. The motherboard has an information-processing semiconductor element mounted thereon.

A printed circuit assembly carrier comprises a carrier frame configured to hold a selected printed circuit assembly of at least two different printed circuit assemblies in at least two different orientations, a first toolless retention feature coupled to a first surface of the carrier frame and configured to retain the selected printed circuit assembly, and a second toolless retention feature coupled to a second surface of the carrier frame and configured to secure the carrier frame in at least ...

A circuit board clamping device is applied to at least two spaced and stacked circuit boards, wherein the two circuit boards are spaced apart and fixed by a plurality of spacing posts. The circuit board clamping device includes a securing member, a pressing member and a forcing member. The securing member can be disposed on one of the circuit boards and adjacent to the spacing posts. The pressing member can be disposed on the securing member and is used to press the spacing posts. The forcing me...

A self powered monitoring device for monitoring an animal's temperature and other vital signs. The device may be mounted in the animal's ear, under the animals skin, or in any location which can be used to generate a reliable indication of the animals temperature and other vital signs. The temperature probe for the device is inserted subcutaneously and thermally and/or electrically connected to the housing of the device. Power for the device is provided by a miniature array of solar cells, the p...
