ELECTRONIC DEVICE FOR WIRELESSLY TRANSMITTING POWER AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17969283 titled 'ELECTRONIC DEVICE FOR WIRELESSLY TRANSMITTING POWER AND METHOD OF OPERATING THE SAME
Simplified Explanation
The abstract describes a first electronic device that wirelessly transmits power to a second electronic device. Here are the key points:
- The first electronic device includes a power transmission circuit, memory, pulse generator, foreign object detection circuit, and control circuit.
- The control circuit wirelessly transmits power to the second electronic device based on an AC input voltage applied to the power transmission circuit.
- A trigger signal is generated by the pulse generator, synchronized with a specified voltage of the input voltage.
- The output value of the foreign object detection circuit is stored in the memory at a specific time identified by the trigger signal.
- The control circuit continuously obtains the output value stored in the memory during a specified time until the next trigger signal is received.
- The presence of a foreign object in the path of power transmission is detected based on the output value obtained during the specified time.

Original Abstract Submitted
A first electronic device for wirelessly transmitting power may include a power transmission circuit, memory, a pulse generator, a foreign object detection circuit configured to detect a foreign object located in a path in which power is wirelessly transmitted through the power transmission circuit, and a control circuit. The control circuit may be configured to wirelessly transmit power to a second electronic device, based on an alternating current (AC) input voltage applied to the power transmission circuit, generate a trigger signal synchronized with a first time corresponding to a specified voltage of the input voltage through the pulse generator, store an output value of the foreign object detection circuit in the memory based on the trigger signal, the output value being identified at the first time, continuously obtain the output value stored in the memory from the memory during a specified time until before the trigger signal of a next period is received at the memory from the pulse generator, and detect the foreign object based on the output value obtained during the specified time.
