    Abstract: Ein Träger zum Übertragen von Hochfrequenzsignalen und eine entsprechende Träger-Layoutmethode. Der Träger besteht aus einem Substrat, Leitungsdrähten und Bezugsebenen auf dem Substrat. Bei der Träger-Layoutmethode werden die Impedanz und die Dicke des Trägers entsprechend des Hochfrequenzsignals und die Layoutparameter entsprechend der Impedanz und Dicke festgelegt. Zu den Layoutparametern gehört eine Leitungsschicht, die auf die Leitungsdrähte aufgetragen wird, ein koplanarer Wellenleiter zwischen den Bezugsebenen und die Leitungsdrähte, wobei sich auf den Leitungsdrähten raue und abgesetzte Bereiche befinden. Das Substrat hat einen hohen dielektrischen Verlustfaktor. Das Layout wird entsprechend den oben festgelegten Layoutparametern ausgeführt, um die Verluste der Hochfrequenzsignale bei der Übertragung zu erhöhen.

    Abstract: Apparatus and method for assembling an isolation cover to a main body of a circuit board using a press-fit device having mechanism (13) attached to a drive mechanism (15 — see figs 3, 5). Preferably comprising handle (155). The cover 30 has positioning portions 301 pass through respective holes in the board 50. The press-fit device base has a supporting portion 113 receiving first (fig 6a) the cover 30 and then the board (fig 6b) 50 on top so that the positioning portions 1331 extending past the underside of the board to face the press-fit means (13 figs 3, 5). The driving mechanism presses the press-fit means onto the board and cover so as to bend and fasten ends of the positioning portions 301, preferably via a central portion continuing to move downwards (see figures 6e, 6f) relative to sprung guiding and bending elements 133.

    Abstract: The hand-held electronic device includes a central processing unit, a memory unit, a state-detecting unit, a state-determining unit, a main power supply unit, a standby power supply unit, and a power supply switching unit. After determining the presence of a fall state, the state-determining unit will output a fall instruction and which causes the central processing unit to enter a low current mode; meanwhile, the power supply switching unit monitors power output and continues to supply low-potential power. In case of a fall of the hand-held electronic device, the device and method protect operation data and reduce the otherwise power-consuming current. The less power-consuming current is conducive to the reduction of capacitance required for a backup battery. The low current mode is effective in reducing the time taken to recover the operation mode of the electronic device.

    Abstract: A modular keyboard includes an upper casing, a lower casing corresponding to the upper casing, an electric conduction element and a circuit board. The upper casing includes a first side and a second side opposite to each other, and a plurality of press keys disposed on the first side. The lower casing is set for sealing the second side, and an enclosure space is formed between the upper casing and the lower casing. The electric conduction element is installed on the second side in the enclosure space, and the circuit board is installed between the electric conduction element and the lower casing. With a supersonic welding technique, the upper casing and the lower casing are engaged with each other to seal the enclosure space and isolate the electric conduction element in the enclosure space and the circuit board from the exterior.

    Abstract: An assembly device includes a base having a supporting portion upon which an isolation cover and a main body are disposed. A press-fitting mechanism is movably connected to the base, and includes a press-fitting portion facing the supporting portion and disposed corresponding in position to the supporting portion, and further portions for guiding and bending second positioning portions. The further portions are movably disposed on external side faces of the press-fitting portion. The press-fitting mechanism also has first portions for holding the further portions to the external side faces of the press-fitting portion, and has second portions passing through upper ends of the further portions. A drive mechanism is disposed at the base and has a drive portion connected to the press-fitting mechanism, for driving the press-fitting mechanism to move towards the supporting portion via the drive portion, so as to bend and fasten ends of second positioning portions.

    Abstract: Eine Hybridschaltung für eine sehr schnelle digitale Teilnehmerleitung (VDSL) blockiert Rauschen und weist eine Transceiver-Einheit, ein Spannungstransformationsmodul, einen Gleichstrom-(DC)-Sperrkondensator, eine Empfangseinheit und eine Übertragungseinheit auf. Das Spannungstransformationsmodul blockiert das Rauschen, welches als Ergebnis der Übertragung eines Upstream-Signals und eines Downstream-Signals an der Transceiver-Einheit erzeugt wurde, und weist eine erste Spannungstransformationseinheit und eine zweite Spannungstransformationseinheit auf. Der DC-Sperrkondensator ist zwischen Primformationseinheit in Reihe geschaltet, um zu verhindern, dass der Direktstrom in der VDSL die Übertragung des Upstream-Signals und des Downstream-Signals beeinflusst. Dementsprechend vereinfacht die Hybridschaltung den Schaltungsentwurf der VDSL, senkt Kosten, die auf die elektronischen Komponenten zurückzuführen sind, und verringert die für das Schaltungslayout erforderliche Fläche.
