Wireless power for chargeable and charging devices

This invention describes a chargeable device that can receive wireless power. It works by detecting several different wireless chargers that might use various communication methods or frequencies. The device then samples these chargers to find one that can provide power, specifically mentioning near-field resonance or inductive coupling technologies.

Why it matters: Filed before wireless charging was common. The widespread adoption of various wireless power standards and the maturation of flexible RF electronics since 2010 make multi-protocol detection more feasible and desirable.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedRF electronics, protocol switching logic
