    摘要: In one embodiment there is a toy vehicle having a low inductance motor powered by a high frequency switched voltage at a frequency high enough to create continuous conduction. The vehicle further includes an H-bridge circuit configured to control a direction of the motor and an adjustable high frequency DC-DC switch configured to convert a supply voltage to an output voltage, lower than the supply voltage, for use by the H-bridge circuit to power the low inductance motor in a forward or reverse direction. In addition, a processor is included and has instructions configured to change the output voltage from the DC-DC switch from a first voltage to a second voltage.

    摘要: In one embodiment there is a toy vehicle having a motor configured to cause a motion of an element of the toy. The motion of the element further accessible for manipulation by a human to in turn rotate the motor. The toy vehicle further having a processor configured to detect a back electromotive force ("EMF") voltage generated by the rotation of the motor due to the manipulation by a human, and the processor being further configured to include at least a sleep state and a wake state. The processor have a function configured to transition between the sleep state and the wake state when the detected back EMF voltage reaches a predetermined value.
