With respect to claims 10, 20, HWANG in view of Lim disclose the method of one of the claims, further comprising: in response to determining that the measured frequency of the digital pings is not in the frequency range, conveying a second wireless charging protocol identification number, different than the first wireless charging protocol identification number, to the wireless power transmitting device. Paragraphs 0045-0049 discloses that if the frequency is mismatched/low frequency the Qi protocol is selected.
With respect to claim 12, HWANG in view of Lim disclose the method of claim 11, wherein transmitting the protocol identification packet comprises transmitting the protocol identification packet using amplitude-shift keying (ASK) modulation. Lim discloses communicating using an amplitude shift keying (ASK), paragraph 0103.
With respect to claim 13, HWANG in view of Lim disclose the method of claim 11, further comprising: after transmitting the protocol identification packet, beginning to receive wireless power from the wireless power transmitting device for charging a battery in the electronic device. HWANG and Lim disclose a charging system for charging batteries of electronic devices, once the protocol is selected.
With respect to claim 14, HWANG in view of Lim disclose the method of claim 10, wherein the first and second wireless charging protocol identification numbers comprise different versions of a wireless charging standard. Lim discloses a wireless power transmission device and transmitting a control signal with information of wireless charging standard version during authentication, paragraphs 0331-0034.
With respect to claim 17, HWANG in view of Lim disclose the method of claim 10, wherein the frequency range comprises a single frequency value selected from 128 kHz, 326 kHz, 360 kHz, 1.78 MHz, and 13.56 MHz. Lim discloses that the frequency may be defined as 87 to 205 kHz or 87 to 145 kHz.
With respect to claim 18, HWANG in view of Lim disclose the method of claim 10, wherein the frequency range comprises multiple discrete frequency values selected from 128 kHz, 326 kHz, 360 kHz, 1.78 MHz, and 13.56 MHz. Lim discloses that the frequency may be defined as 87 to 205 kHz or 87 to 145 kHz, paragraph 0103 discloses using a specific frequency.
With respect to claim 19, HWANG in view of Lim discloses the apparatus necessary to complete the recited method steps, as discussed above in the rejection of claim 1.
With respect to claim 21, HWANG in view of Lim disclose the method of claim 20, further comprising: in response to determining that the measured frequency of the ping signals is outside the first and second frequency ranges, conveying a third wireless charging standard version number, different than the first and second wireless charging standard version numbers, to the wireless power transmitting device. HWANG discloses in paragraphs 0008-0011 selecting based on the detected frequencies different wireless charging standard versions.
With respect to claim 22, HWANG in view of Lim disclose the method of claim 21, further comprising: conveying the first wireless charging standard version number, the second wireless charging standard version number, or the third wireless charging standard version number to the wireless power transmitting device by transmitting a protocol identification packet via the coil.
