Exchanging Data Charger TRIZ Cases
- Wireless Power Transmitter Slot Signaling for Foreign Object Detection
Slot-count and slot-length packets let a wireless charger coordinate foreign object detection during power transfer with lower loss and less receiver risk.
- Wireless Power Slot Control for Stable Received Power
Periodic slot extension based on estimated received power helps wireless loads avoid power shortages in changing radio environments.
- Wireless Power Coil Selection via Magnetic Coupling Coefficient
Control circuitry selects transmit coils based on magnetic coupling coefficients to optimize power transfer.
