Patent number: 11945945Abstract: A resin including up to 99.99 weight percent (wt. %) of a first polyolefin grafted with a functional group selected from an ethylenically unsaturated carboxylic acid, a carboxylic acid anhydride, an ester functional group or a combination thereof; and 0.01 to 3.0 wt. % of a tin oxide-based catalyst, where the resin includes 0.2 wt. % to 1.5 wt. % of the functional group from the first polyolefin, the wt. % based on a total weight of the resin. The first polyolefin can be selected from a polyethylene, a polypropylene, an ethylene/alpha-olefin copolymer, a propylene/alpha-olefin copolymer and combinations thereof. The tin oxide-based catalyst can be selected from dibutyltin oxide, dioctyltin oxide and combinations thereof. The resin can be used in a multilayer structure, where a Layer A comprises the resin and a Layer B comprises a polyester, where a first major surface of Layer A is in adhering contact with the second major surface of Layer B.Type: GrantFiled: May 22, 2019Date of Patent: April 2, 2024Assignees: Dow Global Technologies LLC, Regents of The University of MinnesotaInventors: Kunwei Liu, Alex Michael Jordan, Christopher John Ellison, Christopher Ward Macosko, Christopher M.

Publication number: 20240006822Abstract: Electrical connectors for very high speed signals, including signals at or above 112 Gbps. Effectiveness of shielding along the signal paths through the mating electrical connectors may be enhanced through the use of one or more techniques, including enabling two-sided shielding, connections between shield members and between shield members and grounded structures of printed circuit boards to which the connectors are mounted, and selective positioning of lossy material. Such techniques may be simply and reliably implemented in high density connector using one or more techniques. An electrical connector may include core members held by a housing together with leadframe assemblies attached to the core members. The core members may include features that would be difficult to mold in a housing and may include both shields and lossy materials in locations that would be difficult to incorporate in a leadframe assembly.Type: ApplicationFiled: September 12, 2023Publication date: January 4, 2024Applicant: FCI USA LLCInventors: Douglas M. Johnescu, Gregory A. Hull, Mark E. Lauermann, Scott Martin, Jason John Ellison, Jan De Geest, Charles Cooper, Mark R. Gray, William Tanis, Steven E. Minich

Patent number: 11817657Abstract: A direct mate orthogonal connector for a high density of high speed signals. The connector may include right angle leadframe assemblies with signal conductive elements and ground shields held by a leadframe housing. High frequency performance may be achieved with members on the leadframe that transfer force between a connector housing, holding the leadframe assemblies, and a portion of the leadframe housing holding the signal conductive elements and the shields near their mounting ends. Core members may be inserted into the housing and mating ends of the conductive elements of ground shields may be adjacent the core members, enabling electrical and mechanical performance of the mating interface to be defined by the core members. The core members may incorporate insulative and lossy features that may be complex to form as part of the connector housing but may be readily formed as part of a separate core member.Type: GrantFiled: August 24, 2022Date of Patent: November 14, 2023Assignee: FCI USA LLCInventors: Jason John Ellison, Douglas M.

Patent number: 11791585Abstract: Electrical connectors for very high speed signals, including signals at frequencies at or above 112 GHz, with high density. Such connectors may be formed with fine features molded into portions of the connector housing to support closely spaced signal conductors. The signal conducts may nonetheless be accurately positioned, which leads to uniform impedance and other electrical characteristics that enable high frequency operation through the use of skeletal members that restrain bowing and twisting of housing components that position, directly or indirectly, the signal conductors. The skeletal members may be simply incorporated into the housing components by stamping a metal skeleton from a metal sheet in conjunction with one or more carrier strips. The housing component may be overmolded around the skeleton and then severed from the carrier strips.Type: GrantFiled: January 27, 2021Date of Patent: October 17, 2023Assignee: FCI USA LLCInventors: James J.

Publication number: 20230257179Abstract: A resealable flap device in the form of a sheet, for applying to or incorporating in packaging, comprises: a lower layer of flexible material, and an upper layer of stiff material. The sheet is cut through both layers to outline a flap portion, the cut leaving an edge in a hinge region, the upper layer being removed behind the line of the hinge region. In this way the flexible lower layer forms a hinge that is easy to handle and does not spring back, while the stiff upper layer maintains the shape of the flap.Type: ApplicationFiled: April 27, 2023Publication date: August 17, 2023Inventors: Ian David Michael BELL, Christopher John ELLISON

Patent number: 10932076Abstract: A local device of an auditory device system is configured to perform a process that switches between operating modes. As part of the process, the local device may determine a wireless quality parameter indicative of a current environment for wireless communication with the contra device. Additionally, based on the one or more local input audio signals and the wireless quality parameter, the local device may determine whether to change a local active operating mode of the local device from a bilateral mode to a binaural mode or from the binaural mode to the bilateral mode. The local device may generate a local output audio signal based on the one or more local input audio signals in accordance with the local active operating mode and may produce sound based on the local output audio signal.Type: GrantFiled: July 31, 2019Date of Patent: February 23, 2021Assignee: Starkey Laboratories, Inc.Inventors: Ivo Merks, John Ellison, Ke Zhou
