Patent number: 11817075Abstract: Disclosed herein are implementations of acoustic metamaterial structures and geometric configurations of acoustic metamaterial structures which produce sound amplification or cancellation. An acoustic metamaterial device for using with a sound source includes a plurality of fins, where each fin is made from a very dense material with respect to air which creates the anisotropic properties of the acoustic metamaterial device, where each fin has a length dimension, a width dimension, and a thickness dimension, the width and length dimension being equal and substantially perpendicular to the direction of sound wave propagation from the sound source, where each fin is sized different from other fins along the width and length dimension, and where the plurality of fins are interconnected such that planes formed by the width and length dimension of each fin faces perpendicular to the sound wave propagation direction from the sound source.Type: GrantFiled: November 29, 2022Date of Patent: November 14, 2023Assignee: Jabil Inc.Inventors: David Donald Logan, Katelyn Christensen, Andrew Thomas Ferguson, Arthur Ray Junior Cruz Paquia, Calvin Saechao

Publication number: 20210265099Abstract: The disclosure provides at least an apparatus, system and method for providing a flexible planar inductive coil, such as may be embedded in a product. The apparatus, system and method may include at least one conformable substrate, and a matched function ink set, printed onto at least one substantially planar face of the at least one substrate. This printing may form at least one layer of additive conductive traces capable of receiving current flow from at least one source and layered into successive ones of the conductive traces about a center axis within a plane of the at least one conformable substrate.Type: ApplicationFiled: May 3, 2021Publication date: August 26, 2021Applicant: JABIL INC.Inventors: Sai Guruva AVUTHU, Mark Edward SUSSMAN, David Donald LOGAN, Mary Alice GILL, Nabel M.

Publication number: 20210113132Abstract: A disposable vital signs monitor patch includes hydrogel based conductive adhesives which contacts skin. A medical tape bonds to the skin and has printed silver-silver chloride electrodes. The hydrogel based conductive adhesives interact between the skin and the printed silver-silver chloride electrodes. A double-sided medical tape bonds to the medical tape. A printed circuit board assembly (PCBA) includes a vital signs sensor, a flexible battery, a light emitting device (LED), connects to the printed silver-silver chloride electrodes, and bonds to the double-sided medical tape. A polyethylene foam includes a cut-out for the flexible the LED. The PCBA bonds to the polyethylene foam layer. A plunger operates within a cut-out on the polyethylene foam layer. An acrylic adhesive transfer tape bonds to the acrylic adhesive transfer tape. The medical tape, the double-sided medical tape, the polyethylene foam, and the acrylic adhesive transfer tape bond to seal against environmental exposure.Type: ApplicationFiled: June 20, 2019Publication date: April 22, 2021Applicant: Nypro Inc.Inventors: Yusuf Abu Tayeb Bhagat, Patrick John Verdon, Daniel Robert Parsons, Ralph Hugeneck, Mark Edward Sussman, David Donald Logan, Sai Guruva Reddy Avuthu, Girish Satish Wable

Publication number: 20200328495Abstract: Disclosed herein are implementations of devices and methods for side mounting of microelectromechanical systems (MEMS) transducers on tapered horn antennae. A hole may be made in a sidewall of a tapered horn antenna, where the hole may be substantially cylindrical, tapered and the like. In an implementation, an internal port opening of a MEMS microphone may be aligned with the hole and attached to the sidewall of the tapered horn antenna. In an implementation, the hole may be tapered with a diameter at one end the same or slightly larger than the diameter of the port opening of the MEMS microphone and a larger diameter at another end of the hole. In an implementation, a tube may be used to connect the internal port opening of the MEMS antenna to the hole in the tapered horn antenna. In an implementation, the tapered horn antenna may have multiple holes, each having its respective MEMS transducer.Type: ApplicationFiled: April 10, 2019Publication date: October 15, 2020Applicant: Jabil Inc.Inventors: David Donald Logan, Katelyn Christensen
