  • Publication number: 20140103870
    Abstract: The present invention provides wireless power supply systems that wirelessly supply power to a remote device for rapidly charging a charge storage capacitor, which charges a battery with the power stored in the charge storage capacitor. This allows the remote device to be positioned near the inductive power supply for rapid charging of the charge storage capacitor and allows battery charging to continue even after the remote device is removed from the inductive power supply.

  • Patent number: 8692639
    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.

  • Publication number: 20130039395
    Abstract: A communication system that uses keyed modulation to encode fixed frequency communications on a variable frequency power transmission signal in which a single communication bit is represented by a plurality of modulations. To provide a fixed communication rate, the number of modulations associated with each bit is dynamic varying as a function of the ratio of the communication frequency to the carrier signal frequency. In one embodiment, the present invention provides dynamic phase-shift-keyed modulation in which communications are generated by toggling a load at a rate that is a fraction of the power transfer frequency. In another embodiment, the present invention provides communication by toggling a load in the communication transmitter at a rate that is phase locked and at a harmonic of the power transfer frequency. In yet another embodiment, the present invention provides frequency-shift-keyed modulation, including, for example, modulation at one of two different frequencies.

    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.

  • Publication number: 20120119588
    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: 20120112552
    Abstract: A selectively controllable electromagnetic shield having an electromagnetic shielding material and a mechanism for selectively generating an aperture in the shield. The mechanism for selectively generating an aperture may be a magnetic field source that generates a magnetic field of sufficient strength to substantially saturate all or a portion of the shielding material. For example, a permanent magnet or DC electromagnet may be used to selectively saturate the shield. In its un-saturated state, the magnetic shield has a high permeability and functions as a flux path for the magnetic field. Once saturated, the permeability of the shield is substantially reduced so that the magnetic field lines are no longer drawn into the shield to the same degree. As a result, once saturated, a substantially greater amount of the electromagnetic field may flow through or around the shield in the saturated region.
