A capacitor housing includes an electrically conductive cup having a wall and a bottom, and an electrically insulating envelope which substantially covers an exterior of the cup and which includes an opening at a bottom of the cup. The opening is smaller than the bottom of the cup. The capacitor housing also includes a fill element which is substantially heat-conductive and disposed inside the opening and a cover element which is substantially electrically insulating, that covers at least part of the bottom of the cup and overlaps at least part of the envelope.

A modular stackable USB hub system including a stackable USB. The stackable USB hub having an upstream power port for mounting to other upstream components in the stackable component system. The upstream power port includes an upstream power port connector, a voltage conductor and ground conductor for receiving voltage and ground from the upstream component to supply the high current requirements of the USB hub in high power applications. The stackable USB hub further includes a downstream power port for mounting to other downstream components in the modular stackable component system. The downstream power port includes a downstream power port connector, a voltage conductor and a ground conductor. The voltage and ground conductors are connected to the respective voltage and ground conductors of the USB upstream power port connector for passing voltage and ground to the downstream component connected to the downstream power port. The modular stackable USB hub system includes other components such as a base unit having a suitable power port for releasably mounting to the stackable USB hub.

An enclosure for a data storage system comprises at least first and second cast magnesium parts joined by rivets, each of which is made of a suitable material that provides compressive strength superior to that of the cast magnesium. Each rivet is of a height or thickness equal to the sum of the thickness of the parts to be riveted. Each such rivet has flat end surfaces and its body is peripherally concave between its ends. The rivet is embedded in the two parts, and the parts flow radially against the concave body of the rivet. No drilling is required, and the parts are held in carefully defined position while being joined, so that the assembled enclosure satisfies strict dimensional tolerances.

A base enables the elevation of a panel to be selectively adjusted. The base includes a fixed flap, a supporting flap assembly and a hinge. The fixed flap is attached to the backside of the panel. The supporting flap assembly supports the panel. The hinge connects the fixed flap and the supporting flap assembly. The supporting flap assembly includes a top flap and a fan-wheel. The top flap has a protrusion on a surface thereof, and the fan-wheel has a plurality of recesses that are positioned to selectively engage the protrusion. The fan-wheel is connected to the top flap by a pivot that enables the fan-wheel to turn with respect to the top flap. The hinge enables the fixed flap and the supporting flap assembly to turn around the shaft of the hinge to position the supporting flap assembly with respect to the fixed flap. The elevation of the base can be adjusted by changing the extent to which the fan-wheel is turned with respect to the top flap.

A structure and a circuit of an input/output (I/O) port bar to connect between a computer and a computer peripheral. The structure of the I/O port bar has a laminate, a loop and a sliding member (with a pushing portion, a first protrusion portion and a second protrusion portion). Thus constructed, the connecting cable can be restored to the inside of the I/O port bar. In the circuit of the I/O port bar, a power switching circuit is formed to control whether the power of the main circuit is supplied by an external computer via the connecting cable or directly by an external DC power source.

A laptop computer has a base and a cover with a display monitor that are connected together by a hinge. The base and cover have congruent trapezoidal shapes that give the laptop a unique appearance. A pair of segregated right and left keyboards are mounted to the base. Each keyboard is rotated by a small angle from the center of the base to align with the natural position of the arms of the user. The keyboards are further articulated such that their front ends are elevated relative to their rearward ends. Alternate embodiments of the invention utilize various mechanisms for articulating the keyboards. In addition, the keys on each keyboard may be arranged in a curvilinear formation. The laptop has a wedge that is slidably mounted to the rearward end of the base for varying the angle of inclination of the keyboards. The wedge can raise or lower the angle of the keyboards to suit the preference of the user. The laptop also has a pair of touch pads with different sensitivities, as well as a track point or track ball for moving the screen cursor.
摘要:
The present invention relates to a cover structure for a wireless communication device arranged at least partly as a standard expansion card, and the cover structure (3) being provided with at least one cover surface (3a, 3b). The cover surface (3a, 3b) is provided with at least one elongated bracing groove (G1 to G3) for increasing the dimensional stability of the cover surface (3a, 3b, 4a, 4b, 4c). In an advantageous embodiment of the cover structure (3), the thickness of the cover structure (3) at the bracing groove corresponds substantially to the thickness of the cover structure (3) at the cover surface (3a, 3b), and the bracing groove (G1 to G3) extends substantially over the cover surface (3a, 3b) and the depth of the bracing groove (G1 to G3) is smaller than the thickness of the cover structure (3) at the cover surface (3a, 3b). The present invention relates also to a method in the manufacture of the cover structure for a wireless communication device. The present invention relates further to a wireless communication device which is arranged at least partly as a standard expansion card and comprises at least one cover structure (3) provided with at least one cover surface (3a, 3b). In an advantageous embodiment of the wireless communication device, the bracing groove (G1 to G3) is arranged transverse to the longitudinal axis of the wireless communication device.
摘要:
A computer system including a chassis having a wall with a raised mounting portion protruding therefrom and a mounting flange attached adjacent to the wall. A peripheral device is pivotally mounted on the mounting flange. A resilient damping member is positioned adjacent the wall for being engaged by the peripheral device. The resilient damping member is compressed from a first height to a second height in response to the peripheral device being pivoted from a first position to a second position for reducing impact loadings associated with installing the peripheral device in the computer system. The resilient damping member controls the impact imposed on the peripheral device.
