Abstract: A stabilizing mouthpiece includes features that reduce or prevent displacement of the mouthpiece either laterally or forward and backward when the mouthpiece is in use. In one implementation, the stabilizing mouthpiece may include one or more lateral shift guards that rest adjacent to inner or outer surfaces of a user's molars, incisors, or cuspids. In another implementation, the stabilizing mouthpiece may include elongated ridges or biased grips that resist posterior-to-anterior movement of the mouthpiece.

Abstract: An arc fault protection circuit and method, provides arc fault protection in a multiphase power system by actuating a plurality of disconnect switches to disconnect the source from the load in response to detecting arcing proximate the load. As well, in response to detecting the arc, a plurality of impedances are introduced into the current path between said source and said load, with each of the impedances increasing the impedance between the source and the load along one phase, prior to the plurality of disconnect switches disconnecting the source from the load.

Abstract: A mouthguard has a flexible frame, and has bite tabs extending from the rear surface of the frame for engaging the wearer's teeth. The bite tabs extending from the rear surface of the frame for engaging the wearer's teeth. A narrow split may be provided between the anterior bite tabs that allows the bite tabs to maintain their flexibility. The flexible frame lays against the outer surface of the teeth and extends into the buccal folds superiorly and interiorly of the cheek where the muscles hold it in place. Grooves may be positioned lengthwise along the frame above and below the bite tabs for purposes of flexibility and to allow the muscles of the cheek to press the upper and lower extensions of the frame close to the bone for better retention and comfort. The teeth engage the bite tabs, thus preventing the teeth from clashing together and protecting the temporomanibular joint (TMJ). One or more air holes may be provided in the front portion of the mouthguard permitting easy breathing.

Abstract: A resilient composition including a thermoplastic material and gas pockets dispersed therein, where the pockets being formed by a blowing agent. A mouthpiece including a resilient thermoplastic material having a quantity of gas pockets dispersed therein. A method of making a mouthpiece achieved by first mixing a predetermined quantity of blowing agent with a resilient thermoplastic material. The mixture is then heated to a predetermined temperature forming gas pockets therein from the decomposition of the blowing agent. The mixture is then ejection molded in a mold to form the mouthpiece. A mouthpiece including a U-shaped base having a U-shaped cross-section. The base including a lower, horizontal floor with upwardly extending inner lingual and outer labial walls and having a posterior section proximate the user's molar teeth and an anterior section proximate the user's canine and incisor teeth.

Abstract: A custom fit body part guard or shield is disclosed which includes a thin shell formed from an ionomer resin which has a softening temperature within the range of 60.degree.-80.degree. C. The shell material of approximately 1-6 millimeters thickness is partially molded to fit the area of the body where the device is intended to be used. A layer of perforated foam material can be adhered to the inside surface of the guard to further protect the user's skin and absorb or distribute impact energy during use. By holding the guard under ordinary hot tap water it can be softened to a moldable consistency. By firmly applying and holding the guard on the surface of the area of the body where it is intended to be used and allowing the guard to cool to ambient temperature the guard will take a permanent set to a custom shape which follows the exact shape and contour of the body part.

Abstract: A protective device for protecting the information on magnetically encoded areas of plastic cards comprising strips of a ferro-magnetic amorphous composition having a metal-glass characteristic situated adjacent and covering the magnetically encoded areas on either side so as to redirect any corrupting electromagnetic and statomagnetic fields. In a preferred embodiment, the protective strips are incorporated in a card holding unit.

Abstract: Ampules may be cleaned and quality controlled by submerging frangible, sealed, partly filled, floatable ampules in a container in an ultrasonic cleaning tank bath in such manner as to not only clean all the ampules but also break a large portion of any flawed ampules, thereafter separating the intact ampules from the shattered ampules, collecting, washing, drying and packaging the former.
