Publication number: 20210152916Abstract: A wireless earbud system includes a neckband having a first end and a second end defining a curved member configured to contour to a neck of a wearer. A first earbud includes a first speaker and a first ear tip. A second earbud includes a second speaker and a second ear tip. A first opening disposed in the first end of the neckband defines a first compartment configured to receive and store the first ear tip of the first earbud. A second opening disposed in the second end of the neckband defining a second compartment configured to receive and store the second ear tip of the second earbud. The neckband, first earbud, and second earbud are in wireless communication with an external device, such that a user can receive incoming communications from the external device.Type: ApplicationFiled: November 19, 2020Publication date: May 20, 2021Inventor: Allen Kohler

Patent number: 7981349Abstract: UHMWPE panels of large width may be ram extruded from a slit die in a stable process, by restraining a panel which exits the die below the crystalline melt temperature against movement away from the die by a back pressure device, so as to exert a back pressure between the back pressure device and the die, the back pressure device preferably constructed of a plurality of differentially adjustable elements so as to be able to compensate for changes in processing characteristics over time. Vertically restraining UHMWPE panels as they further cool also greatly improves product characteristics.Type: GrantFiled: June 11, 2010Date of Patent: July 19, 2011Assignee: Quadrant EPP AGInventors: Joseph V. Gregg, Wesley Allen Kohler

Patent number: 7980839Abstract: Wide panels of UHMWPE having exceptional flatness and surface quality are ram extruded through a slit die equipped with a plurality of individually adjustable cooling zones proximate the panel exit slit and transverse to the machine direction, which cool the panel while the panel is restrained by a back pressure device and preferably a vertical movement restraint. The process is robust and can be run for long product campaigns.Type: GrantFiled: March 23, 2010Date of Patent: July 19, 2011Assignee: Quadrant EPP AGInventors: Joseph V. Gregg, Wesley Allen Kohler, Lyle D. Berning

Patent number: 7803450Abstract: UHMWPE panels of large width may be prepared by a continuous ram extrusion process by employing a slit die which preferably narrows from both sides in a direction transverse to the machine direction, and/or which employs a plurality of transversely positioned cooling zones located on the top and the bottom of the die, proximate the exit thereof. The panel exits the die at a temperature lower than the crystalline melt temperature.Type: GrantFiled: July 21, 2006Date of Patent: September 28, 2010Assignee: Quadrant EPP AGInventors: Joseph V. Gregg, Wesley Allen Kohler
