METHOD FOR DETECTING FOREIGN MATERIAL, AND APPARATUS AND SYSTEM THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18223967 titled 'METHOD FOR DETECTING FOREIGN MATERIAL, AND APPARATUS AND SYSTEM THEREFOR
Simplified Explanation
The abstract describes a power transmission method for a wireless power transmitter.
- The method involves receiving a packet from a wireless power receiver that contains information about a reference quality factor or a reference peak frequency.
- Based on this packet, the method determines whether a foreign object is present in the charging area of the wireless power transmitter.
- A foreign object detection indicator is generated based on the determination and transmitted back to the wireless power receiver.
- The FOD status packet has a length of two bytes, with one byte containing a reservation field and a mode field.
- The reservation field is recorded as zero in all bits.
Original Abstract Submitted
A power transmission method for a wireless power transmitter, the power transmission method including receiving, from a wireless power receiver, a foreign object detection (FOD) status packet including information on a reference quality factor or a reference peak frequency; determining whether a foreign object is present in a charging area of the wireless power transmitter based on the FOD status packet; and generating a foreign object detection indicator indicating whether the foreign object is present in the charging area of the wireless power transmitter based on a result of the determination and transmitting the generated foreign object detection indicator to the wireless power receiver, wherein the FOD status packet has a length of two bytes, wherein one byte of the FOD status packet includes a six-bit reservation field and a two-bit mode field, and wherein all bits of the reservation field are recorded as zero.
