Abstract: The present invention provides an orthodontic appliance including a unitary appliance body positionable about a portion of a single dental arch, where the appliance body may define a lingual portion, a labial-buccal portion, and a contoured portion therebetween. The appliance body may further define an anterior portion and a posterior portion, as well as a first wire coupled to the appliance body, with the first wire extending from the lingual portion of the appliance body to the labial-buccal portion of the appliance body. In addition, a first portion of the first wire may be embedded in the appliance body while a second portion of the first wire extends from the posterior portion of the appliance body. The appliance may further include a second wire disposed about the appliance body between the first wire and the anterior portion of the appliance body. A series of appliances may be used to shift a patient's bite to proper bite orientation.

Abstract: A clothing strap tensioning device has an elastic member having a geometry generally defined by middle, left end, and right end portions, and bounded by upper, lower, left and right edges, and includes mechanical snaps or other releasable attachment mechanisms integrated into the left end and right end portions for enabling releasable attachment of the end portions to each other to form the elastic member into a loop. The tensioning device is looped around a pair of spaced vertical straps of a brassiere, such that the straps are drawn toward each other medially to prevent the straps from slipping down the shoulders of a wearer and to impart an upward lift to the wearer's breasts. The geometry of the elastic member also prevents twisting of the straps.

Abstract: A fin retention and deployment mechanism that has the advantage of providing for the deployment of aerodynamic control surfaces on command without the need for an additional actuation device or control circuitry separate from the actuator that controls the angle of the fins during flight. The actuator that is already required for operation of the control surfaces after deployment initiates the deployment of the fins, as well. A latch mechanism comprises a retaining member and a lath, which engages the retaining member enabling a biasing mechanism to force the fins from a stowed position to a fully deployed position.

Abstract: The invention relates generally to a roll damping apparatus for a spinning projectile having a first section and a second section rotatably attached about a roll axis. The roll damping apparatus comprises a first portion attached to the front section, and a second portion attached to the rear section. The first portion is adapted to cause a braking frictional force to act on the second portion, the braking force being effective to control the spin rate of the front section relative to the rear section. The invention further relates to a spinning projectile having a roll damping apparatus.
