    Abstract: A multi-layer micro-printed circuit board (PCB) is disclosed, which defines a magnetic component (500), such as a transformer, using planar technology. Instead of using the traditional twelve-layer PCB incorporating both a primary and a secondary winding, this invention stacks multiple PCBs (525, 530, 535), each having four or six layers and each including a single winding (either the primary or the secondary). The PCBs are stacked in an offset arrangement such that the pins (501-504A) penetrating the PCB or PCBs including the primary winding or windings do not penetrate the PCB or PCBs including the secondary winding or windings. Additionally, this offset arrangement prevents the pins penetrating the secondary PCBs from penetrating the primary PCBs in the same manner. This offset configuration thereby avoids significant flashover problems associated with current planar components. Moreover, the invention describes an arrangement whereby a jumper or other connection can be used to connect the windings in a series or in a parallel configuration allowing the user to configure the component according to user-required parameters.

    Abstract: A multiple supply voltage peripheral component interconnect (PCI) connector 50 is disclosed which replaces connectors that are keyed for a specific signaling voltage. A single connector receives all current types of PCI keyed card edge connectors and supplies the correct signaling voltage thereto. The type of PCI card is identified and the appropriate signaling voltage is switched to the signaling power input (Vio) using industry standard conditions at selected pin locations rather than using unique keying of cards and connectors to assure a match between the signaling voltage required by the card and the signaling voltage supplied at the connector. Detection and control circuitry 57 senses the presence of grounded or open conditions at selected pin locations indicative of the type card present in the connector and switches the signaling power supply to the correct voltage source. Also, the connector may be buffered to enable connection to a single logical PCI bus 55 irrespective of the signaling voltage supplied to the card 58. Further, the buffered connectors can be replicated to enable numerous cards, with any mix of signaling voltages, to be attached to the single logical bus.

    Abstract: A high power slide tuning capacitor (200) integrated into a circuit board adapted to function at RF and microwave frequencies. The capacitor (200) is comprised of a dielectric substrate (26) with a cavity (28) cut into a side of the substrate (26); a ground plane (24) mounted on a bottom surface of the dielectric substrate (26); a microstrip patch (22) mounted on a top surface of the dielectric substrate (26) and positioned above the cavity (28); and a movable dielectric stub (30) which engages the cavity (28) such that a variable length of the stub (30) is positioned beneath the microstrip patch (22). The microstrip patch (22) can be coupled to a desired circuit trace (20), effectively forming a shunt capacitor to ground.

    Abstract: Platine mit mehreren integrierten Schaltungen 2, die mit einem zuführbaren ersten Versorgungspotential V1 arbeiten. Die Platine 1 weist eine Potential-Anpassungsanordnung 3 auf, deren Ausgangspotential das erste Versorgungspotential V1 ist und deren Eingangspotential ein der Platine 1 zuführbares zweites Versorgungspotential V2 ist. Die Potential-Anpassungsanordnung kann beispielsweise eine Diode oder ein Spannungsregler sein.

    Abstract: The present invention provides an apparatus for altering an electrical signal between a first device and a second device. The apparatus includes a support structure or interconnection member having at least two surfaces with a plurality of contacts on each surface. The contacts are arranged in a predesignated pattern to mate with the conductors of each of the devices. In a typical application, the apparatus will be used to connect a microprocessor powered by approximately 3.3V to a printed circuit board of a system using a power supply of approximately 5.0V.
