An oral appliance may include a generally u-shaped base portion having a tray and labial flange, where the labial flange has a plurality of pockets adapted to receive corresponding circuitry components. The oral appliance may also include circuitry arranged on the labial flange and having components arranged in respective pockets of the plurality of pockets and a cover portion sealingly arranged on the labial flange and covering the circuitry.

A light, durable, and user friendly cover for a laptop computer that integrates the protective qualities of hard shell cases with the aesthetics of soft cut-and-sew covers is disclosed. The cover includes top and bottom panels configured to cover the display and keyboard portions, respectively. Each panel is independent and separate from the other and each is formed as a unitary component of a molded resilient polymer material, such as polycarbonate, that is configured to reversibly and retentively snap-fit over the outer surface of the laptop computer. Each panel includes a raised lip along its perimeter edge region that defines an internally extending recessed region on the panel's outer surface. Fabric and/or leather overlays are positioned, sized and adhesively coupled atop the recessed regions and are protected from delaminating, fraying, and/or peeling by the raised perimeter lip.

A screen protector installation tray can include an alignment tray and a screen protector retained within the alignment tray. Also, a method for applying a mobile device screen protector to a mobile device, including retaining a screen protector within an alignment tray, applying the alignment tray to the mobile device, interfacing the screen protector with a screen of the mobile device, transferring the glass screen protector from the alignment tray to the mobile device, and removing the alignment tray. Additionally, a mobile device screen protector installation kit, including an alignment tray, a screen protector, and instructions for applying a screen protector to a screen of a mobile device.

An armor plate is provided having a lamination of an embedded reinforcement basalt fiber mesh within a laminated cast metal alloy; and at least two layers of an aramid fiber. A process to make the armor plate can include suspending a basalt weave within a mold; heating aluminum 6061 or 7075 alloy to a molten state; pouring the molten aluminum into the mold; cooling the resultant matrixed aluminum to ambient temperature; and laminating at least two layers of ballistic fiber to the matrixed aluminum.

A modular armor system configured to be readily attached and detached from a frame surrounding a window in a vehicle or other structure, such as a building. The modular armor system may be configured to provide any desired ballistics protection rating. In one embodiment, the modular armor system includes a ballistics-grade armor panel having an outer strike face and an inner surface opposite the outer strike face. The modular armor system also includes a fastener coupled to the ballistics-grade armor panel. The fastener is configured to detachably couple the ballistics-grade armor panel to the frame surrounding the window in the vehicle or other structure.

Ballistic resistant composite materials having high positive buoyancy in water are provided. More particularly, provided are foam-free, buoyant composite materials fabricated using dry processing techniques. The materials comprise fibrous plies that are partially coated with a particulate binder that is thermopressed to transform a portion of the binder into raised, discontinuous patches bonded to fiber/tape surfaces, while another portion of the particulate binder remains on the fibers/tapes as unmelted particles. The presence of the unmelted binder particles maintains empty spaces within the composite materials which increases the positive buoyancy of the composites in water.

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.

In a process for the production of pore-free polyurethane elastomer moldings with Shore D hardness of at least 60 in accordance with DIN 53505, (a) polyesterdiol with OH number from 20 to 100 mg KOH/g and (b) a chain extender composed of diol with molar mass below 300 g/mol, is mixed with (c) isocyanate prepolymers obtainable via reaction of diisocyanate with polyesterols with functionality from 1.95 to 2.2 and with OH number from 20 to 200 mg KOH/g to form a reaction mixture. The reaction mixture is charged to a mold and hardened to form the polyurethane elastomer. Polyurethane elastomer moldings are thus obtainable by this process, and these polyurethane moldings may be used as cladding component for commercial vehicles, bodywork component in vehicle construction, or a cladding component of a machine installation.

A ballistic resistant article includes a first layer that has first unidirectional fibers disposed in a first polymer matrix. The first polymer matrix is composed of a thermoset polyurethane. A second layer is laminated to the first layer. The second layer includes second unidirectional fibers disposed in a second polymer matrix. The second unidirectional fibers are cross-oriented with respect to the first unidirectional fibers.

A method of making and deploying a bullet proof vest that can be used to protect students at points of education. The method involves a process of combining/bonding fifteen fiberglass sheets with fiberglass resin in a time specific manner and then pressing the fiberglass sheets together thereby forming a fiberglass plate. A pair of fiberglass plates formed using the present method are thereafter inserted within a vest that has a front and a back receiving pocket. The vest has a strap that is used to tighten the vest on a user wearing the vest. The bullet proof vest of the present invention is inexpensive, lightweight and may also include a tracking device that will inform the authorities of the deployment of the vest. The tracking device of the bullet proof vest will connect to a central monitoring system and will be stored/deployed within an educational desk.
