Patent ID: 7786622

Claim:
A juvenile product comprising: a structural assembly having a foot that supports a child occupant area above a rest surface; a power adapter comprising a first AC-to-DC converter to generate a DC transmission voltage from a line power source; a power cable coupled to the power adapter and configured to carry the DC transmission voltage; a power transmitter coupled to the power cable and comprising a transmitter coil and a DC-to-AC converter coupled to the transmitter coil such that an AC current flows through the transmitter coil based on the DC transmission voltage; a power supply comprising a receiver coil disposed in the foot and configured for generation of induced current in the receiver coil via inductive coupling with the transmitter coil when the foot rests upon the power transmitter, and further comprising a second AC-to-DC converter coupled to the receiver coil to generate DC power based on the induced current; and an electrical load coupled to the power supply and configured for operation via the DC power.
