US Patent Issued to Northeastern University on July 7 for "Ultra-low power beamforming wireless power transfer system" (Massachusetts Inventor)

ALEXANDRIA, Va., July 7 -- United States Patent no. 12,676,511, issued on July 7, was assigned to Northeastern University (Boston).

"Ultra-low power beamforming wireless power transfer system" was invented by Aatmesh Shrivastava (Weston, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Wireless power transfer (WPT) efficiency is enhanced using an ultra-low power (ULP) distributed beamforming technique. A phase and frequency offset correction technique is used for beam-forming optimization, a backscattering communication technique is used to reduce power over-head, and a new rectifier and MPT method is used for high efficiency RF-to-DC conversion."
