  • Patent number: 8716950
    Abstract: Data may be encoded onto a direct current power line by modulating the current on that direct current power line. One method of modulating the current is by placing an inductor on the power line and then using a controlled transistor that turns on and turns off. The inductor will ensure that current keeps flowing but the transistor will induce changes in the current pattern. The excess current from when transistor is turned off must be diverted. Furthermore, to create symmetrical current changes, the inductor should be reverse biased. Thus, a circuit is created that sinks the excess current from when the transistor is turned off and used to reverse bias the inductor.

  • Patent number: 8089291
    Abstract: A junction-current probe is provided which can measure a current flowing in a junction port adapted to connect a circuit board or an electronic apparatus to a chassis under the condition that the circuit board or electronic apparatus is packaged to the chassis. Structurally, the current probe has a circular or rectangular insulator having a hole in the center, a coiled conductor wire for converting linkage flux into voltage, an insulating member for preventing the insulator from making electrical contact with surroundings, an extraction lead for connecting opposite ends of the conductor wire to a cable and the cable for connection to a measurement unit. The current probe is reduced in thickness within in a range in which the condition of packaging to the chassis can remain unchanged.

  • Patent number: 8072308
    Abstract: A high voltage split core transformer and method of assembling same is provided by which the coupling factor is improved. A split core assembly is surrounded by a secondary winding that is precisely located in a burner assembly housing. Conductive members are encased within the housing and, in conjunction with traces provided on a printed circuit board enclosing the housing cavity, define first and second primary windings about the core secondary winding. This arrangement reduces the number of turns in the secondary winding and allows the use of larger cross-sectional wire which increases the current carrying capability thereof, making the transformer suitable for D1-D5 automotive headlamp applications.

  • Publication number: 20110221560
    Abstract: An integrated circuit inductor may have upper and lower loop-shaped line portions that are connected in series. The upper and lower portions may have 45° bends that form hexagonal or octagonal loops. Each loop portion may have one or more turns. Intervening metal-free regions of metal routing layers may be formed between the two layers to reduce capacitive coupling. Each loop portion may have sets of two or more metal lines shorted in parallel by vias. The upper and lower loops may be laterally offset or nested to reduce capacitive coupling.

  • Publication number: 20110128110
    Abstract: A configuration of a pair of inductor coils within a local measuring range which can comprise a position range or an angle range. For the coil configuration, a nominal distance to a damping part is predefined which comprises an eddy current damping part which covers the coils, to a certain degree. In the evaluation circuit, the coils are connected to a capacitor, forming an oscillator part, whose inductance and capacitance determine a resonant frequency. The characteristic curve, oscillator frequency as a function of the position or the angle is linear. The rectangular inductors of the pair of coils overlap within the measuring range. The linear characteristic curves have a common point of rotation, outside of the measuring range, which is independent from interferences by the measuring configuration.

  • Publication number: 20110109413
    Abstract: Instead of being made from one continuous piece of material, a coil includes multiple flat coil segments that are stacked together and electrically coupled in series. In many embodiments, the coil segments are U-shaped segments, and the segments are arranged so that each segment is rotated (e.g., by 270 degrees) with respect the segment it follows. The stacked coils may then be fastened together using, for example, bolts through the corners of the coil segments. The combined coil segments form a continuous coil.

  • Publication number: 20110080249
    Abstract: The present invention relates to a new layout for inductive loops of the electromagnetic-induction system, and particularly relates to a new layout for inductive loops of the electromagnetic-induction system which can be integrated with another type of input system. The inductive loop structure of the layout for inductive loops of the electromagnetic-induction system comprises a plurality of -shaped regions, a plurality of switches, a plurality of grounding lines, a grounding switch, and a plurality of signal ports. The -shaped regions are connected with each other to form a fence-shaped inductive loop structure, but the -shaped regions are not interlaced with each other. By this way, the difficulties and the complication for layout for inductive loops of the electromagnetic-induction system are decreased. Therefore, it helps the layout for inductive loops of the electromagnetic-induction system to be integrated with another type of input system into one system.

  • Publication number: 20110076979
    Abstract: A shielded differential inductor forms a high quality factor (high-Q) inductor that is configured to attenuate frequency spurs and/or noise from magnetic coupling generated by electrical structures on or off of a substrate as well as interference received by other components from magnetic coupling generated by the inductor. The shielded differential inductor includes a differential inductor and a shield that substantially isolates the electrical field between the inductor and the substrate to reduce substrate current loss. The shield includes sets of finger structures that extend beyond the width of the inductor and a hub and spoke configuration of ground conductors that connect the sets of finger structures to ground.
