METHOD FOR DETECTING FOREIGN MATERIAL, AND APPARATUS AND SYSTEM THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18223969 titled 'METHOD FOR DETECTING FOREIGN MATERIAL, AND APPARATUS AND SYSTEM THEREFOR
Simplified Explanation
- The patent application describes a wireless power transmitter that can transmit power to a wireless power receiver. - The wireless power transmitter includes a wireless communication unit that can communicate with the wireless power receiver. - The transmitter also includes a controller that can determine if there is a foreign object present in the charging area of the transmitter based on a foreign object detection (FOD) status packet received from the receiver. - The wireless communication unit can then transmit a foreign object detection indicator to the receiver, indicating whether a foreign object is present in the charging area. - The FOD status packet includes information on a reference quality factor or a reference peak frequency. - 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 wireless power transmitter that transmits power to a wireless power receiver, the wireless power transmitter including a wireless communication unit configured to communicate with the wireless power receiver; and a controller, wherein the wireless communication unit receives a foreign object detection (FOD) status packet from the wireless power receiver, wherein the controller determines whether a foreign object is present in a charging area of the wireless power transmitter on the basis of the FOD status packet, wherein the wireless communication unit transmits, to the wireless power receiver, a foreign object detection indicator indicating whether the foreign object is present in the charging area of the wireless power transmitter on the basis of a result of the determination, wherein the FOD status packet includes information on a reference quality factor or a reference peak frequency, 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.
