    Abstract: An Ethernet cable used with an Ethernet test-set allows a single connection to an Ethernet port of a network element while maintaining individual connections to separate ports on the test-set. The far-end of the signal path is a single Ethernet cable port having its transmit and receive pins interconnected. The far-end port interconnections cause a test signal which has traveled to the far-end port to be returned to the test-set and to be receive in a test-set port other than the originating port Two signal paths can be simultaneously tested with the same test-kit. Interconnections between the test-set ports by way of the cable maintain a “no-signal”alarm disabled, which otherwise would be energized because there is no signal being received in the port from which the test signal originated.

    Abstract: A flat high definition multimedia interface (HDMI) cable. The flat cable that is less visible in comparison to a round HDMI cable for wall mounted television setup. An HDMI connector is coupled to the flat cable. An active circuit isolates physical characteristics of the HDMI connector. The active circuit causes the flat cable to appear shorter than its actual length during HDMI compliance testing using impedance testing. Moreover, the active circuit causes a consumer electronic control (CEC) line, a display data channel (DDC) line and transition minimized differential signal (TMDS) line to actively terminate for reducing parasitic capacitance from the length of the flat cable during HDMI compliance testing. Thus, the isolation allows the flat cable to satisfy HDMI compliant testing.

  • Patent number: 6894231
    Abstract: The present invention relates to a system and method for equalizing the capacitance between at least two lines of a bus running in parallel for a portion of their length. The system and method include determining a twisting pattern for the lines using an algorithm. After determining the twisting pattern, the lines are twisted according to the pattern so that each of the lines runs along every other line for a same distance across the length of the bus.

  • Publication number: 20040238194
    Abstract: A device and method are provided for reducing impedance, impedance discontinuities, and signal-loop area in flex cables used for a signal path. In one embodiment of the invention, a flex cable is provided for reducing the impedance and length of a return-signal path. The flex cable includes a signal conductor, and a return-signal conductor not connected to ground. The flex cable may also include a ground conductor. Such a flex cable provides a shorter- and lower-impedance return-signal path between a signal source and receiver than do conventional flex cables. In another embodiment of the invention, a method is provided that includes the steps of delivering a signal from a signal source to a signal receiver with a flexible conductor, and returning the signal from the signal receiver to the signal source with another flexible conductor other than ground.

  • Patent number: 6365827
    Abstract: A conductor arrangement for a lumped element circulator in which the mutual inductive or capacitive coupling between conductors is different at different points of coupling between conductors. The conductors (11L, 11R, 12L, 12R, 13L, 13R) may taper from one end to another. The conductors (31L, 31R, 32L, 32R, 33L, 33R) may include tabs (34, 35, 36) at conductor cross overs. The conductors (41L, 41R, 42L, 42R, 43L, 43R) may include notches (44, 45, 46) at conductor cross overs. The conductors may include transitions (55) in the centrelines (54) of conductors (51L, 51R, 52L, 52R, 53L, 53R). The conductors (61L, 61R, 62L, 62R, 63L, 63R) may curvilinear.

  • Patent number: 6300846
    Abstract: A flexible circuit member includes first and second pseudo-twisted flexible conductors on a flexible dielectric substrate. The first pseudo-twisted conductor is on a first side of the substrate and the second pseudo-twisted conductor is on a second side of the substrate. Each pseudo-twisted conductor includes a periodic pattern with the first pseudo-twisted conductor being shifted longitudinally relative to the second pseudo-twisted conductor by one half of a period of the periodic pattern. A set of first and second additional conductors are also provided on the dielectric substrate. The first additional conductor is on the first side of the substrate and is spaced from and generally follows the shape of the first pseudo-twisted conductor. The second additional conductor is on the second side of the substrate and is spaced from and generally follows the shape of the second pseudo-twisted conductor.

  • Patent number: 6201333
    Abstract: A conductor bar and a method for producing a conductor bar of a stator winding for an electric machine, in particular a generator, having a stator as well as a rotor disposed rotatably therein. Each conductor bar is formed of component conductors which are made from conductive material, are situated one above another in pairs, traverse a stack from a top layer obliquely to a bottom layer and each have uniform cranks in the vicinity of the top layer and in a bottom region. The cranks of each two component conductors placed one above another and assigned to one another in pairs are disposed offset in the longitudinal direction at a spacing relative to cranks of a succeeding or preceding pair of component conductor bars. The component conductors are disposed in two stacks located next to one another and laterally adjoining one another. The component conductors are each situated one above another in pairs and are each mutually interlocked through the use of the laterally neighboring component conductors.
