METHOD FOR DETECTING FOREIGN MATERIAL, AND APPARATUS AND SYSTEM THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18223457 titled 'METHOD FOR DETECTING FOREIGN MATERIAL, AND APPARATUS AND SYSTEM THEREFOR
Simplified Explanation
The abstract describes a wireless power reception method that involves transmitting status packets to a wireless power transmitter and receiving detection indicators in response.
- The method includes transmitting a first and second foreign object status packet to the wireless power transmitter.
- The wireless power transmitter sends back a first and second foreign object detection indicator, which can be a positive or negative response signal.
- If both detection indicators are positive, the method proceeds with a first power transmission procedure.
- If at least one detection indicator is negative, the method either requests termination of power transmission or performs a third power transmission procedure different from termination.
Original Abstract Submitted
A wireless power reception method including transmitting a first foreign object status packet and a second foreign object status packet to a wireless power transmitter; receiving, from the wireless power transmitter, a first foreign object detection indicator including a positive response signal or a negative response signal for the first foreign object status packet and a second foreign object detection indicator including a positive response signal or a negative response signal for the second foreign object status packet; power receiving of performing a first power transmission procedure when both the first foreign object detection indicator and the second foreign object detection indicator include the positive response signal, or performing to a second power transmission procedure of requesting termination of power transmission or performing to a third power transmission procedure different from the termination of the power transmission when at least one of the first foreign object detection indicator and the second foreign object detection indicator includes the negative response signal.
