Patent number: 11764614Abstract: An electrically conductive material configured having at least one opening of various unlimited geometries extending through its thickness is provided. The opening is designed to modify eddy currents that form within the surface of the material from interaction with magnetic fields that allow for wireless energy transfer therethrough. The opening may be configured as a cut-out, a slit or combination thereof that extends through the thickness of the electrically conductive material. The electrically conductive material is configured with the cut-out and/or slit pattern positioned adjacent to an antenna configured to receive or transmit electrical energy wirelessly through near-field magnetic coupling (NFMC). A magnetic field shielding material, such as a ferrite, may also be positioned adjacent to the antenna. Such magnetic shielding materials may be used to strategically block eddy currents from electrical components and circuitry located within a device.Type: GrantFiled: August 15, 2022Date of Patent: September 19, 2023Assignee: NuCurrent, Inc.Inventors: Alberto Peralta, Md. Nazmul Alam, Vinit Singh, Sina Haji Alizad

Patent number: 11366141Abstract: A current sensor includes a lead frame having a plurality of leads, at least two of which form a current conductor configured to carry a current that generates a magnetic field and a substrate having first and second opposing surfaces, the first surface proximate to said current conductor and the second surface distal from the current conductor. A first magnetic field transducer is disposed on the substrate and a first coil is disposed on the substrate adjacent to the first magnetic field transducer, wherein the first magnetic field transducer and the first coil are positioned on a first side of the current conductor. A second magnetic field transducer is disposed on the substrate and a second coil is disposed on the substrate adjacent to the second magnetic field transducer, wherein the second magnetic field transducer and the second coil are positioned on a second side of the current conductor.Type: GrantFiled: January 28, 2021Date of Patent: June 21, 2022Assignee: Allegro MicroSystems, LLCInventors: Steven Daubert, Sina Haji Alizad, Srujan Shivanakere, Maxwell McNally, Alexander Latham
