  • Patent number: 8129864
    Abstract: An inductive power supply that maintains resonance and adjusts duty cycle based on feedback from a secondary circuit. A controller, driver circuit and switching circuit cooperate to generate an AC signal at a selected operating frequency and duty cycle. The AC signal is applied to the tank circuit to create an inductive field for powering the secondary. The secondary communicates feedback about the received power back to the primary controller. The power transfer efficiency may be optimized by maintaining the operating frequency substantially at resonance, and the amount of power transferred may be controlled by adjusting the duty cycle.

  • Publication number: 20120001644
    Abstract: The specification discloses a simple and effective system for tracking position and rotation of an object or portable device located within an electromagnetic field. The electromagnetic field may be produced by a primary coil, which inductively couples with one or more secondary coils located within a portable device. The relative strength of this inductive coupling may be used to determine the position, rotation, or both of the portable device relative to the primary coil.

    Abstract: A dielectric barrier discharge lamp assembly for a fluid treatment system. The lamp assembly can include an inductive secondary, first and second electrodes coupled to the inductive secondary, and a lamp including a dielectric barrier interposed between the first and second electrodes. The dielectric barrier can define a discharge chamber including a discharge gas, and one of the first and second electrodes can extend within the discharge chamber. The inductive secondary can be adapted to receive power from a nearby inductive primary to promote a dielectric barrier discharge in the discharge chamber. The resulting dielectric barrier discharge can generate ultraviolet light for the treatment of air or water, or for other applications.

  • Patent number: 7973635
    Abstract: A multilayer printed circuit board (“PCB”) coil that simulates a coil formed from litz wire. The PCB includes a plurality of alternating conductor and insulating layers interconnected to cooperatively form the coil. Each conductor layer includes a trace that follows the desired coil shape and is divided into a plurality of discrete conductor segments. The segments are electrically connected across layers to provide a plurality of current flow paths (or filaments) that undulate between the layers in a regular, repeating pattern. The coil may be configured so that each filament spends a substantially equal amount of time in proximity to the paired coil and therefore contributes substantially equally to the self or mutual inductance of the coil. Each conductor layer may include a plurality of associated traces and intralayer connector that interconnected so that each filament undulates not only upwardly/downwardly, but also inwardly/outwardly in a regular, repeating pattern.

  • Publication number: 20110050382
    Abstract: A flux concentrator and method for manufacturing a flux concentrator is provided. The method can include combining powdered soft magnetic material, a binder, a solvent, a internal lubricant; mixing the materials to create a mixture, evaporating the solvent from the mixture, molding the mixture to form a flux concentrator, and curing the flux concentrator. The flux concentrator may be laminated and broken into multiple pieces, which makes the flux concentrator more flexible. Breaking the flux concentrator does not significantly affect the magnetic properties. Since the permeability of the binder is very similar to that of air, adding tiny air gaps between the fractions is not significantly different than adding more binder.

  • Patent number: 7883619
    Abstract: A water treatment system including a UV bulb, a moisture detector, and a control circuit responsive to the moisture detector to terminate power to the bulb when moisture is detected. The moisture detector includes a nonconductive substrate and a pair of conductors on the substrate. When moisture is not present, the detector is nonconductive. However, when moisture accumulates on the detector, the moisture provides a conductive path between the conductors so that the detector becomes conductive. When moisture is detected, the control circuit terminates power to the bulb and/or provides an appropriate indication to the system user.

  • Patent number: 7821208
    Abstract: An inductively powered gas discharge lamp assembly having a secondary circuit with starter circuitry that provides pre-heating when power is supplied to the secondary circuit at a pre-heat frequency and that provides normal operation when power is supplied to the secondary circuit at an operating frequency. In one embodiment, the starter circuitry includes a pre-heat capacitor connected between the lamp electrodes and an operating capacitor located between the secondary coil and the lamp. The pre-heat capacitor is selected so that the electrical flow path through the pre-heat capacitor has a lesser impedance than the electrical flow path through the gas of the lamp when power is applied to the secondary circuit at the pre-heat frequency, and so that the electrical flow path through the pre-heat capacitor has a greater impedance than the electrical flow path through the gas when power is applied the operating frequency.
