AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 1 and 15 is confirmed.
Claims 2-14 and 16-26 were not reexamined.
1. A base system for inductive charging of an electronic device comprising an inductive charging receiver and a battery electrically coupled to the inductive charging receiver, the base system comprising:
an inductive charging coil;
a coil drive circuit electrically coupled to the inductive charging coil, wherein the coil drive circuit provides power to the inductive charging coil by switching a voltage input to the inductive charging coil at an operating frequency;
a current detection circuit electrically coupled to the inductive charging coil; and
a microcontroller, wherein the microcontroller is configured for:
operating in a first mode of operation using a first protocol, wherein the first protocol is an inductive charging communication-and-control protocol that comprises uni-directional messaging, wherein the first mode of operation comprises:
receiving, using the current detection circuit, a first communication from the inductive charging receiver of the electronic device, wherein the first communication is based on the first protocol; and
regulating power delivered to the battery of the electronic device in response to the received first communication; and
operating in a second mode of operation using a second protocol, wherein the second protocol is an inductive charging communication-and-control protocol that defines bi-directional messaging, wherein the second mode of operation comprises:
receiving, using the current detection circuit, a second communication from the inductive charging receiver of the electronic device, wherein the second communication is based on the second protocol;
transmitting, by modulating the operating frequency with the coil drive circuit, a frequency-modulated third communication to the inductive charging receiver of the electronic device, wherein the frequency-modulated third communication is based on the second protocol; and
regulating power delivered to the battery of the electronic device in response to the received second communication;
wherein the first mode of operation is associated with a first power level and the second mode of operation is associated with a second power level, and
wherein and the first power level and the second power level are different.
