Abstract: In one aspect, the disclosure relates to self-healing systems including at least a structural polymer, a plurality of optical fibers or polymer waveguides embedded in the structural polymer, and a plurality of micro-channels through the structural polymer, wherein the micro-channels are configured to deliver a curing composition to at least one site of damage in the system. In another aspect, the curing composition can include a photo-polymerizable liquid monomer, and, optionally, a sensitizer, a photo-initiator, and/or a toughening agent, articles comprising the same, and methods of in situ self-healing of damage including Mode-I fractures using visible irradiation from the optical fibers or polymer waveguides to photo-polymerize the liquid monomer.

Abstract: Disclosed herein is an intrinsically self-healing composite based upon in situ thermal remendability of an embedded polymeric interphase. The fiber-reinforced composite (FRC) material may incorporate a thermoset polymer with a defined glass transition temperature (Tg) and/or a thermoplastic material of amorphous or semi-crystalline nature. The polymeric interphase can be incorporated as a plurality of particles, fibers, meshes, films, or 3D-printed structures. The self-healing composite includes a resistive heating component as a structural element that minimizes electrical energy demand and impact on mechanical integrity. Healing occurs in situ via resistive heating and can be enabled below, at, or above the glass-transition temperature of the FRC matrix, demonstrating viability for in-service repair under sustained loads. In addition to providing rapid healing functionality, the polymeric interphase increases inherent resistance to interlaminar fracture.

Abstract: Some embodiments disclosed herein relate to an auxiliary optical device having one or more optical components, such as lenses, attached to a retainer portion. The retainer portion is configured to removably attach to mobile electronic devices such as mobile phones, tablet computers, media players, and the like. The retainer portion may include a movable mounting portion that achieves or maintains a substantially parallel orientation with respect to a face of a mobile electronic device even when a sidewall of the retainer portion is not parallel with respect to the face. An optical component may be mounted to the mounting portion, and movement of the mounting portion can facilitate a parallel orientation of the optical axis of the optical component with respect to an optical axis of an onboard camera of the mobile device.

Abstract: An auxiliary lens assembly for releasably connecting one or more auxiliary lenses to an electronic device with an on-board camera, such as a mobile smartphone or a tablet computer. The lens assembly includes a first bracket, a second bracket movable coupled to the first bracket, and a release assembly coupled to the first and second brackets. When actuated by a user force, the release assembly moves the second bracket in a first direction away from the first bracket to increase a separation gap between the two brackets from an initial to an expanded position and when the user force is removed, the release assembly moves the second bracket in a second direction towards the first bracket to decrease the separation gap back to the initial position.

Abstract: A multi-lens system can be configured to be selectively attachable to a mobile electronic device having a user-facing onboard camera lens and an outward-facing onboard camera lens. The multi-lens system can attach to the mobile electronic device in at least a first position and a second position. The first lens component in the first position is configured to be in optical alignment with the user-facing onboard camera lens and simultaneously the second lens component is configured to be in optical alignment with the outward-facing onboard camera lens. The first lens component in the second position is configured to be in optical alignment with the outward-facing onboard camera lens and simultaneously the second lens component is configured to be in optical alignment with the user-facing onboard camera lens. A portable attachment accessory can be configured to be selectively attachable to a lens system that is configured to receive a portion of a mobile electronic device.
