FOCUSING PULSED SIGNAL TRANSMISSIONS IN MULTIPATH WIRELESS POWER DELIVERY ENVIRONMENTS
First Claim
1. A method of focusing pulsed signal transmissions in a multipath wireless power delivery environment, the method comprising:
- transmitting, from a single transmitting antenna, a pulsed training signal over a plurality of paths to a receiving antenna in the multipath wireless power delivery environment,wherein the pulsed training signal includes at least one signal pulse;
identifying timing and phase information corresponding to the pulsed training signal as received by the receiving antenna over each of the plurality of paths;
configuring transmission settings associated with the transmitting antenna based on the timing and phase information,wherein the transmission settings focus a pulsed wireless power transmission signal for reception by the receiving antenna; and
transmitting the pulsed wireless power transmission signal to the receiving antenna.
