Claim Text:
1. An apparatus to receive power wirelessly from a transmitter, comprising: a power transfer component configured to receive power wirelessly from the transmitter; a circuit coupled to the power transfer component, the circuit configured to reduce a received voltage when activated; a controller configured to provide a control signal to activate the circuit when the received voltage reaches a first threshold value and to deactivate the circuit when the received voltage reaches a second threshold value, wherein the control signal further includes a pulse that is inverted if the received voltage reaches the first threshold value and that is non-inverted if the received voltage falls to the second threshold value; and an antenna configured to transmit the pulse to the transmitter, wherein the pulse indicates to the transmitter that the received voltage reached the first threshold value.
