Abstract:

Disclosed herein are system, method, and computer program product embodiments for inductively charging a sport ball. An embodiment operates by transmitting from a resonant circuit a calibration signal in response to detecting a charging base, and transmitting from the resonant circuit a charging state in response to receiving power at the resonant circuit. Another embodiment operates by transmitting from a resonant circuit a presence signal, receiving at the resonant circuit a calibration signal from a second resonant circuit in response to transmitting the presence signal, and transmitting from the resonant circuit power to the second resonant circuit in response to receiving the calibration signal
