  • Patent number: 8545284
    Abstract: An inductively powered toy vehicle and an associated track with inductive charging segment. The vehicle may include a secondary coil, a drive motor, an electrical power storage device connected between said secondary coil and said drive motor, and a wireless communications unit. The charging segment may include a primary coil, a sense circuit operable to detect the presence of the vehicle based on a change in the detected impedance of the primary coil, and a power control unit operable to provide a time-varying current to the primary coil when the vehicle traverses the charging segment. The primary coil is positioned within the race track adjacent the track upper surface. The vehicle drive motor may be operable at first and second speed settings, and a remote control device can provide operating instructions to the vehicle wireless communications unit.

  • Patent number: 8531153
    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.

  • Publication number: 20120133324
    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: 7815149
    Abstract: A mechanism uses a magnetic field to dock a satellite to a host vehicle. A docking component of the mechanism residing on the host vehicle has a magnet that is used to induce a coupled magnetic field with a docking component of the mechanism residing on the satellite. An alignment guide axially aligns the docking component of the satellite with the docking component of the host device dependent on the coupled magnetic field. Rotational alignment guides are used to rotationally align the docking component of the satellite with the docking component of the host device. A ball-lock mechanism is used to mechanically secure the docking component of the host vehicle and the docking component of the satellite.
