Abstract:
Die Erfindung betrifft eine Planar-Positioniervorrichtung, mit einem Stator, der eine Spulenanordnung aus Flachspulen umfasst, einem in Betriebslage der Positioniervorrichtung dem Stator gegenüberliegend angeordneten Läufer, der eine planare Magnetanordnung aus mehreren Magnetreihen aufweist, wobei die durch die planare Magnetanordnung aufgespannte Ebene parallel zur Ebene der Spulenariordnung angeordnet ist, einer Positionserfassungseinrichtung zur Erfassung der Lage des Läufers relativ zum Stator, und einer Auswertungs- und Steuereinrichtung zur Auswertung von Positionssignalen der Positionserfassungseinrichtung und zur Steuerung einer Bestromung der Spulenanordnung zur Positionssteuerung des Läufers bezüglich des Stators, wobei die Spulenanordnung je n x 3 ( n ≥ 1) miteinander verschachtelte, langgestreckte Flachspulen in einer ersten und zweiten Ausrichtung der Spulenanordnung umfasst, die im größten Teil ihres Verlaufes als Leiterzüge einer ersten Ebene einer Mehrebenen-Leiterplatte ausgeführt sind, und die Leiterzüge der drei zusammengehörenden Flachspulen Überkreuzungsbereiche einschließen, die in einer zweiten Ebene der Mehrebenen-Leiterplatte verlaufen.
Abstract:
A rigid-flex PCB includes an array of rigid PCB "islands" interconnected by a flexible PCB formed into flexible connectors. The conductive and insulating layers of the flexible PCB extend into the rigid PCBs, giving the electrical connections to the rigid PCBs added resistance to breakage as the rigid-flex PCB is repeatedly stressed by bending and twisting forces. In addition, the durability of the rigid-flex PCB is enhanced by making the power and signal lines driving the rigid PCBs redundant so that a breakage of a line will not necessarily affect the operation of the rigid PC B to which it is attached. The rigid-flex PCB is particularly applicable to light, pads used in phototherapy, wherein LEDs mounted on the rigid-PCBs are powered and controlled through the redundant lines in the flexible PCB.
Abstract:
Embodiments of the present invention relate to circuit layouts that arc compatible with printing electronic inks, printed circuits formed by printing an electronic ink or a combination of printing and conventional blanket deposition and photolithography, and methods of forming circuits by printing electronic inks onto structures having print-compatible shapes. The layouts include features having (i) a print-compatible shape and (ii) an orientation that is either orthogonal or parallel to the orientation of every other feature in the layout.
Abstract:
The present invention involves chip-to-chip communication systems for reducing Far-End Crosstalk (FEXT) through the use of novel polarity swapping to negate the cumulative effect of FEXT. Skew adjustment is used to improve the FEXT cancellation from polarity swapping. The polarity reversal location or locations among FEXT sources are optimized to achieve maximum FEXT cancellation. The novelty polarity swapping technique can be applied to a wide variety of systems that can benefit from FEXT reduction.
Abstract:
The present disclosure relates to a telecommunications jack including a housing having a port for receiving a plug. The jack also includes a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing, and a plurality of wire termination contacts for terminating wires to the jack. The jack further includes a circuit board that electrically connects the contact springs to the wire termination contacts. The circuit board includes first and second conductive layers separated by a relatively thin dielectric layer. The first and second conductive layers include a crosstalk compensation arrangement having spaced-apart capacitor members. The relatively thin dielectric layer allows a high level of capacitance to be generated between the capacitor members.

Abstract:
A communications connector (200) includes: a dielectric mounting substrate (220); a plurality of conductors (222a-228b) mounted in the mounting substrate; and a wiring board (259). Each of the conductors includes a fixed end portion mounted in the mounting substrate and a free end portion, each of the free end portions being positioned in side-by-side and generally parallel relationship, and each of the fixed end portions being positioned in side-by-side and generally parallel relationship. The wiring board is positioned between the fixed and free end portions of the conductors, the wiring board being generally perpendicular to the conductors, the wiring board including first (276a) and second (276b) conductive traces that are electrically insulate from each other. First and second conductors are electrically connected with the first and second traces, the first and second conductive traces are arranged on the wiring board to create a crossover between the first and second conductors.
