The methods of precisely performing the plurality of operations on a composite part include detecting a corresponding imprinted feature of a plurality of imprinted features, aligning an operating assembly of an end effector relative to the corresponding imprinted feature, and performing a corresponding operation of the plurality of operations on the composite part.

A breath actuated metered dose inhaler may comprise a canister fire system configured to fire a medicament containing canister in response to patient inhalation. The canister fire system may comprise a pneumatic force holding unit and having a rest configuration in which a metering valve of the canister is in a refill configuration; a prepared configuration in which a canister actuation force is retained by the pneumatic force holding unit and the canister fire system is actuatable by patient inhalation induced airflow; and a fire configuration in which the metering valve is in a dose delivery position. When in the prepared configuration, the force retained by the pneumatic force holding unit may be reduced by less than about 6% over a period of 5 minutes, preferably less than about 3% over a period of 5 minutes.

The invention provides a molded article having excellent mechanical strength, heat resistance, surface roughness, and ferroelectricity. The molded article contains a crystal of a vinylidene fluoride/tetrafluoroethylene copolymer. The crystal is a crystal and is a nano-oriented crystal that has a size of 100 nm or smaller. The molded article has an arithmetic average roughness of 3.0 m or lower.

A method of forming a reusable, non-adhesive protective cover is disclosed which includes extruding first and second layers of a thermoplastic film onto a rotatable cast roll. The first layer has an interior surface and an exterior surface. The second layer is extruded onto the interior surface of the first layer to form a co-extruded laminate. The second layer has an exterior surface exhibiting attachment and release capabilities such that a joint tape can be used to join adjacent sheets of the protective cover together. The co-extruded laminate is then advanced between a nip formed by an embossing roll and a rubber roll whereby the exterior surface of the first layer contacts the embossing roll to form a co-extruded embossed laminate. Lastly, the co-extruded embossed laminate is passed around at least a portion of a chill roll to cool the laminate and form the reusable, co-extruded embossed non-adhesive protective cover.

Devices and methods are provided for making a variable textured breast implant when used in conjunction with a breast implant mandrel having a molding surface and a stem depending therefrom.

Systems and methods for creating a grip surface (104) of a protectant glove (100). The method may comprise dipping a glove mold into a coagulant material (206); dipping the glove mold into a nitrile coating formulation to form an outer surface of the glove (208), wherein a biodegradable material is distributed throughout the nitrile coating formulation; vulcanizing at least the outer surface of the glove to form a protectant outer surface (212); washing at least the outer surface of the glove with an enzyme solution; decomposing, by the enzyme solution, the biodegradable material that is distributed throughout the outer surface of the glove, thereby forming a grip surface of the glove comprising an open-cell structure within the outer surface (216); and drying the glove to form a final glove comprising the grip surface (218).

An optical component is configured to optically connect a light-emitting element and an optical fiber, and includes an optical surface arranged in a middle of an optical path of a light to be emitted from the light-emitting element to the optical fiber to reflect the light. The optical surface includes an optical path area configured to reflect the light and a non-optical path area other than the optical path area, and the optical path area and the non-optical path area are coplanar. The optical path area has a smooth surface, and at least a part of the non-optical path area has a rough surface which is rougher than the optical path area.

Provided herein is a polyurethane tube having a small bending repulsive stress and superior inner-pressure creep characteristics in a flexible polyurethane tube. The present polyurethane tube has a bending repulsive stress of 0.035 N/mm.sup.2 or less, wherein the polyurethane tube is formed so that the difference between the storage elastic modulus E.sub.30 at 30 C. and the storage elastic modulus E.sub.80 at 80 C. is 15% or less of E.sub.30.
