Unidirectional transparent projectile penetration resistant panels and bidirectional opaque projectile penetration resistant assemblies and systems and methods of forming and mounting the same relative to underlying support structures.

[Problem] To suppress changes in the recess depth and shape of a three-dimensional molded shape, and to form a uniform protective layer or ornamental layer along the surface of the molded shape. Also, to provide uniform application to the entire irregularly-formed surface and to suppress air pockets and partial defects of bonding. [Solution] In an adherend W having a three-dimensional molded portion in which a plurality of concavities and/or convexities are molded in a regular arrangement, a thermoplastic coating film larger than the area of an adhesion region is integrally adhered by a three dimensional decorative molding procedure in a predetermined adhesion region that includes the three-dimensional molded portion. The predetermined adhesion region includes all of the three-dimensional molded portion and covers more than half the perimeter of the adherend W incenter cross-sectional view.

A method and apparatus for protecting a structure. The method comprises identifying an exterior shape of the structure; generating a model of a mask based on the exterior shape of the structure; and forming the mask using a three dimensional printer based on the model.

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having enhanced a dynamic storage modulus, which correlates to low composite backface signature.

The invention relates to a method for producing a foam-backed molded component, the method comprising the following steps: a) introducing a cover material in a mold (100), the mold (100) having a negative-profiled surface (310); and b) generating and maintaining a vacuum and/or negative pressure on the side of the cover material facing the mold (100); and c) pouring a foam material in the mold (100); and d) closing the mold (100); and e) molding the foam material; and f) opening the mold (100) and removing a foam-backed molded component, the foam-backed molded component having a profiled surface.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A push-in earplug including an elongate core and outer layer is disclosed. The outer layer includes a sound attenuating portion having a first average density and a stem portion having a second average density, and the second average density is greater than the first average density.

A method and apparatus is presented. A portion is cut from a thermoplastic sheet of a first thermoplastic material based on a three dimensional model. The portion is secured to a mold. The portion and the mold are heated under vacuum to form a structure. The structure may take the form of a protective covering. In some illustrative examples, the mold may be formed of a second thermoplastic material based on the three dimensional model using additive manufacturing.
