Communication Between Devices During Wireless Power Transfer - A simplified explanation of the abstract

  • This abstract for appeared for US patent application number 18341538 Titled 'Communication Between Devices During Wireless Power Transfer'

Simplified Explanation

This abstract describes a wireless power system that consists of a transmitting device and a receiving device. These devices can communicate with each other using in-band communication. The transmitting device uses frequency-shift keying (FSK) modulation to send data to the receiving device, while the receiving device uses amplitude-shift keying (ASK) modulation to send data back to the transmitting device.

During the data transmission from the transmitting device to the receiving device using FSK modulation, the transmitting device constantly checks for any ASK modulation signals from the receiving device. If it detects ASK modulation, it immediately stops the FSK data transmission and processes the ASK modulation to receive data from the receiving device.


Original Abstract Submitted

A wireless power system has a wireless power transmitting device and a wireless power receiving device. The devices in the wireless power system may communicate using in-band communication. The wireless power transmitting device may transmit data to the wireless power receiving device using frequency-shift keying (FSK) modulation. The wireless power receiving device may transmit data to the wireless power transmitting device using amplitude-shift keying (ASK) modulation. While transmitting data to the wireless power receiving device using FSK modulation, the wireless power transmitting device may monitor for ASK modulation from the wireless power receiving device. In response to detecting the ASK modulation from the wireless power receiving device, the wireless power transmitting device may abort the FSK data transmission and process the detected ASK modulation to receive data from the wireless power receiving device.
