  • Publication number: 20090212736
    Abstract: An inductive power supply system to wirelessly charge a remote device based on detected battery characteristics. The system includes an inductive power supply with a primary coil capable of inductively providing power to a secondary coil in a remote device. The inductive power supply and remote device include communication means for wirelessly communicating. The system further includes a remote device, having a battery with detectable battery characteristics. In operation, the remote device is capable of detecting the battery characteristics by applying a qualification charge to the battery. The inductive power supply system is capable of identifying the battery installed in the remote device by analyzing the detected battery characteristics. The inductive power supply system selects an appropriate charging algorithm based on the analyzed characteristics.

  • Patent number: 7560867
    Abstract: A starter for a gas discharge light source is configured to measure an initial resistance of one or more filaments of the gas discharge light source, such as a fluorescent light, each time the gas discharge light source is initially powered via a ballast. The starter may initiate a preheat cycle to heat the one or more filaments. The duration of the preheat cycle may be automatically customized by the starter based on the initial resistance and a target hot resistance that is calculated by the starter based on the initial resistance. The duration of the preheat cycle may be automatically customized by the starter to optimize reliability and the life of the gas discharge light source.

  • Publication number: 20090177908
    Abstract: A wireless power adapter that mounts to the docking station port of a portable computer, such as a laptop computer, notebook computer or tablet computer. The wireless power adapter includes a docking port electrical connector selected to interface with the pre-existing docking port electrical connector on the portable computer. The adapter docking port electrical connector includes power pins to connect with the pre-existing power pins of the portable computer docking port electrical connector. The wireless power adapter may include an inductive secondary to wirelessly receive power from an inductive primary. The wireless power adapter may include a mechanical connector that interfaces with the pre-existing docking station mechanical connector on the portable computer. The present invention may also include a remote inductive power supply having a base adapted to support the laptop and adapter combination.

  • Publication number: 20090174263
    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: 20090120851
    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.

  • Publication number: 20090085706
    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: 20080231211
    Abstract: A power supply to provide electrical power to one or more loads. The power supply may include a resonant air core transformer to provide an adjustable and adaptable source of power to electronic devices. The power supply may include isolated primary-side circuitry and secondary-side circuitry. The primary-side circuitry may include control circuitry that, among other things, provides drive waveforms for the primary-side switching circuitry. In embodiments configured to produce AC output, the secondary-side circuitry may also include switching circuitry. The primary-side control circuitry may provide drive waveforms for the secondary-side switching circuitry. The secondary-side circuitry may include measurement circuitry that measures the current and/or voltage of the output and provides those measurements to the control circuitry through isolation circuitry. The control circuitry may adjust the drive waveforms for the primary-side and/or secondary-side switching circuitry as a function of the measured values.

  • Publication number: 20080164817
    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.
