    • 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.
    • 一种感应动力玩具车和一个带有感应充电段的相关轨道。 车辆可以包括次级线圈,驱动电动机,连接在所述次级线圈和所述驱动电动机之间的电力存储装置,以及无线通信单元。 充电段可以包括初级线圈,感测电路,其可操作以基于检测到的初级线圈的阻抗的变化来检测车辆的存在;以及功率控制单元,其可操作以向初级线圈提供时变电流 当车辆穿过充电段时。 初级线圈位于轨道上表面附近的跑道内。 车辆驱动电动机可以在第一和第二速度设置下操作,并且遥控设备可以向车辆无线通信单元提供操作指令。
