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 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.

A method of making personal protective equipment, such as a push-in earplug, is disclosed. The method includes the steps of covering a substrate with an outer layer that includes an unactivated foaming agent, positioning at least a portion of the outer layer in a mold, and activating the foaming agent such that a portion of the outer layer expands.

An armor production tool including a housing having at least two housing portions that form a substantially air-tight chamber when closed. The tool can include a lower thermal diaphragm forming at least a portion of a mold, and an upper thermal diaphragm forming at least a portion of the mold and capable of engaging the lower flexible membrane. The thermal diaphragms may comprise a thermal transfer membrane, a pressure bearing membrane and a fluid dispersion layer between the thermal transfer membrane and the pressure bearing member. A heating or cooling fluid can be circulated through the fluid dispersion layer to apply heat or to cool the armor part during the molding process. The tool can include a pressure port for pressurizing the chamber and to move the thermal diaphragm towards each other to apply compression on the molded armor part, and a locking mechanism for locking the two housing portions.

A polymeric glazing of a vehicle includes a polycarbonate glazing substrate having interior and exterior vehicle sides, a hardcoat layer applied directly to the interior vehicle side, and a co-extruded film, having polycarbonate and polymethylmethacrylate portions, in direct contact with the exterior vehicle side such that the polymeric glazing lacks a hardcoat layer outside the exterior vehicle side and the polymethylmethacrylate portion forms an outer-most layer of the polymer glazing.

A ballistic shielding material element is provided formed of molecularly oriented layers of material, such a polyethylene or HDPE that is modified using the application of continuous mechanical tension in combination with alternating heating and cooling cycles. The molecularly oriented planar material may then be used in the creation of ballistic resistant material panels through bias lay-up of subsequent layers. Further, the final multilayer composite may be additionally cured to form a final shape, such as a sheet material for construction or three dimensional shapes such as helmets, shields or custom shapes as needed by the end user. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

A method is provided for forming a glass fiber product, by forming a first mixture including dry melt-resistant filiform glass fibers, a fire-retarding solution, and a thickening agent; forming a second mixture including the first mixture and a binding agent, wherein the first mixture and the binding agent being configured to form an expanding foam; and applying the second mixture to a surface prior to the second mixture forming the expanding foam. A method is also provided for forming a glass fiber product, by adding a thickening agent to a fire-retarding solution to form a first mixture; adding a hardening agent to the first mixture to form a second mixture; and adding dry melt-resistant filiform glass fibers to the second mixture to form a paste mixture. Associated apparatuses are also provided.
