  • Publication number: 20230023459
    Abstract: A hearing protection device is presented. The device has a first earmuff connected to a second earmuff by a connector. Each of the first and second earmuffs are configured to receive an ambient sound and provide a dampened ambient sound to a wearer. The device also has a cable, with a cable length, that extends from the first earmuff to the second earmuff. The cable is coupled to the connector by a connection assembly. The connection assembly comprises a plurality of connection mechanisms arranged in a connection plan. Such a hearing protection device gives more freedom of placing the cable in a compact arrangement.

  • Patent number: 10687588
    Abstract: The present invention relates to printed hook components for hook and loop mechanical fasteners, and other components such as on diaper chassis and other personal hygiene articles, and methods for making the same. The hook component comprises an organic polymer, a laser-sensitive agent, and a laser-induced print on the hook component created by the interaction of electromagnetic radiation with the laser-sensitive agent. The hook component can be used in a variety of applications, including mechanical fastening devices for personal hygiene articles such as diapers, adult incontinence pads, and medical gowns.

  • Patent number: 8777473
    Abstract: The present invention provides in one aspect a light device having a light guide. The light guide (20) has at least one major side defining a light extraction side (26). The light device further has at least one fibrous layer (30), typically a non-woven or woven fibrous layer, disposed on the major side of said light guide defining said light extraction side. At the light extraction side, the light device has a plurality of discrete bonding areas (40) at which the at least one fibrous layer is bonded to the major side of said light guide. In a particular aspect, the bonding areas define light extraction elements on the light extraction side. Such an arrangement typically provides for an easy, reliable and cost-effective light device useful for a variety of applications including, for example, illuminating the interior of a vehicle.
