Abstract: A set of headphones has an audio system, a control system with a graphical user interface (GUI) and a digital content management system including a database of digital content, a user authentication system, a processor, and a memory storing executable instructions. The processor is configured to validate a user, download and store digital content upon user authentication, and decrypt and decode the digital content for output via the audio system to an authenticated user. A set of headphones enable one or more users to engage with story content with one or more biometric sensors to capture physiological and emotional responses, such as heart rate, skin conductivity, and/or motion, which are analyzed in real time by one or more of the processors. This adaptive system dynamically modifies the narrative path and content delivery based on the user's responses, creating personalized and immersive storytelling experiences.

Abstract: A system for sharing copyrighted digital content, including a first device configured to be worn by a user, the first device comprising an index system to manage digital content stored on, streamed to, or transmitted to the first device. At least one mechanism is included for sensory playback of the digital content. At least one mechanism is included for forming a wireless local network with at least one second device. In embodiments, an active RFID reader is also included, for use with an object containing a passive RFID tag. The RFID tag functions to perform at least one of: authorize use of the digital content by the first device; act as an index decision node input; authorize the first device and the at least one second device to form the wireless local network; and authorize use of mechanical and software features and functions of the first device.

Abstract: A polymeric material process includes increasing a mobility within a polymer to enables specific alignment of polymer chains.

Abstract: In a featured embodiment, a fan rotor includes a platform. Clevises extend radially inwardly of the platform. Each clevis has an aperture. A hub has hub lugs positioned intermediate spaced ends of the clevises, and apertures. A pin extends through the apertures in the hub and the clevises to connect the platform to the hub. The apertures in the clevises are formed to have an inner surface for supporting the pin. A method of forming a fan blade platform is also disclosed.

Abstract: A composite article lay up comprising a first layer of resin impregnated fiber material and a second layer of resin impregnated fiber material. An open cell material is layered between the first layer and the second layer. The open cell material has no resin during a first stage of a resin cure cycle. The open cell material has passages configured to flow volatiles formed during the first stage of the resin cure cycle. The open cell material is configured to fill with the resin during a second stage of the resin cure cycle. The open cell material is configured to form an integral structure with the first layer and the second layer as part of the composite article at the completion of the resin cure cycle.

Abstract: A composite component and a plated polymer component are disclosed. The composite component may comprise a body portion formed from an organic matrix composite, a first metal coating applied to a surface of the body portion, and an outer metal layer on the first metal coating that is erosion-resistant. The plated polymer component may comprise a polymer substrate, a metal plating layer applied to a surface of the polymer substrate, and at least one selectively thickened region in the metal plating layer. The at least one selectively thickened region may assist in protecting the plated polymer component against wear and/or erosion.

Abstract: An investment mold includes a mold cavity and a refractory investment wall that bounds at least a portion of the mold cavity. At least a portion of the refractory investment wall includes a plurality of fugitive beads. The fugitive beads can be sacrificed to provide voids that control the strength of the refractory investment wall such that the wall fractures at the voids during investment casting to alleviate stress on a solidified metal cast in the mold cavity.
