This abstract first appeared for US patent application 18224379 titled 'METHOD FOR DETECTING FOREIGN MATERIAL, AND APPARATUS AND SYSTEM THEREFOR
Simplified Explanation
- The patent application describes a method for receiving power wirelessly using a wireless power receiver. - The method involves storing information about a reference quality factor and a reference peak frequency. - A foreign object detection (FOD) status packet is generated, which includes the information about the reference quality factor and reference peak frequency. - The FOD status packet is then transmitted to a wireless power transmitter. - The wireless power receiver receives a foreign object detection indicator from the wireless power transmitter, indicating whether there is a foreign object present in the charging area. - The FOD status packet has a length of two bytes, with one byte containing a 6-bit reservation field and a 2-bit mode field. - All bits of the reservation field are recorded as zero.
Original Abstract Submitted
A power reception method for a wireless power receiver, the power reception method including storing information on a reference quality factor and a reference peak frequency; generating a foreign object detection (FOD) status packet including the information on the reference quality factor and the reference peak frequency; transmitting the FOD status packet to a wireless power transmitter; and receiving a foreign object detection indicator indicating whether a foreign object is present in a charging area of the wireless power transmitter in response to the FOD status packet, wherein the FOD status packet has a length of two bytes, wherein one byte of the FOD status packet includes a 6-bit reservation field and a 2-bit mode field, and wherein all bits of the reservation field are recorded as zero.
