WIRELESS CHARGING DEVICE DETECTION WITH PHOTOSENSORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18555684 titled 'WIRELESS CHARGING DEVICE DETECTION WITH PHOTOSENSORS
Simplified Explanation: The patent application describes a device that wirelessly charges a portable electronic device using a wireless charging circuit. The device includes two photosensors, one within the charging range and one outside. A control circuit detects the presence of the electronic device within the charging range based on the signals from the photosensors and activates or deactivates the charging circuit accordingly.
- The device wirelessly charges a portable electronic device.
- Includes two photosensors - one within the charging range and one outside.
- Control circuit detects the presence of the electronic device within the charging range.
- Activates or deactivates the charging circuit based on the signals from the photosensors.
Potential Applications: 1. Consumer electronics for convenient wireless charging. 2. Smart home devices for automated charging processes. 3. Industrial applications for efficient charging of electronic equipment.
Problems Solved: 1. Eliminates the need for physical connection for charging. 2. Provides a more convenient and automated charging process. 3. Ensures efficient use of energy by activating charging only when needed.
Benefits: 1. Simplifies the charging process for users. 2. Reduces wear and tear on charging ports of electronic devices. 3. Improves energy efficiency by activating charging only when necessary.
Commercial Applications: Wireless charging devices can be marketed to consumers as convenient charging solutions for their electronic devices. Additionally, industries can implement this technology for efficient charging of equipment in various settings.
Questions about Wireless Charging Technology: 1. How does wireless charging technology work?
- Wireless charging technology uses electromagnetic fields to transfer energy between a charging pad and a device, eliminating the need for physical cables.

- Wireless charging offers convenience, eliminates the wear and tear on charging ports, and provides a more streamlined charging process.
Original Abstract Submitted
An example device includes a wireless charging circuit to wirelessly charge a portable electronic device. The device further includes a first photosensor positioned within an effective charging range of the wireless charging circuit, the first photosensor to output a first signal, and a second photosensor positioned outside the effective charging range, the second photosensor to output a second signal. The device further includes a control circuit connected to the wireless charging circuit, the first photosensor, and the second photosensor. The control circuit detects the portable electronic device positioned within the effective charging range of the wireless charging circuit by detecting a difference between the first signal and the second signal. The control circuit turns on the wireless charging circuit in response to detecting the difference. The control circuit turns off the wireless charging circuit in response to detecting that the first signal matches the second signal.
