A complete wireless charger.
The process starts with a device such as a phone advertising wireless its availability power charging requirements.
The charger device pans and tilts to maximize this signal. The charging millimeter or microwave charging wave is heavily directional to limit charging beam spread. The beam is also kept time adapt-ably low duty cycle enough to not cause serious burns in case of human skin contact except slight warming to move away from zone.
The radar beam spread is larger to detect humans or animals approaching the charge area. Noise is also monitored to detect nearby activity to change charging duty cycle.
