Abstract
Official abstract text for this publication.
Various embodiments of the present technology relate generally to wireless power systems. More specifically, some embodiments relate to the use of time reversal techniques utilizing time diversity (e.g., different multipath arrivals at the same antenna) to achieve coherency from the same transmission node. For example, instead of initiating outgoing transmissions (e.g., power signals) at the same time, various embodiments can initiate the outgoing signals from the various antennas in a staggered timing that is a reversal of the arrival times of an incoming signal. As a result of staggering the start of the outgoing signals, the signals will arrive at the destination at approximately the same time even though they have traveled different paths having different propagation delays.
First claim
Opening claim text (preview).
What is claimed is: 1. A circuit comprising control circuitry configured to: generate an arrival profile including two or more times of arrival at the circuit for a wireless signal transmitted by a device over multiple paths; and based on the arrival profile, determine: a first time for a first response signal to be transmitted to the device over a first path of the multiple paths; and at least a second time after the first time for at least a second response signal to be tra…
