The release assembly is disposed between the sheath and the inner shaft, and includes a retraction member, a release member, and a retention member. The retraction member can self-retract in length from an extended condition to a retracted condition. The release member can self-expand from a compressed condition to an expanded condition. The retention member is distal the release member. In a delivery state, the sheath end is distal the retention member, the release member is in the compressed condition and the retraction member in the extended condition to retain the prosthesis. In a deployment state, the sheath end is positioned to permit the release member to self-transition to the expanded condition, allowing the retraction member to self-transition to the retracted condition and release the prosthesis.

The present invention is a controlled delivery system that can be incorporated in hair, skin, and fabric care products such as shampoos, conditioners, hair styling products, lotions, creams, liquid laundry detergents, fabric softener, and other hair, skin, and fabric care products to effectively deliver a broad range of active agents and sensory markers onto the hair, skin, and fabric. The system also prolongs the release rate of the active agents or sensory markers over an extended period of time, or provides heat triggered release of the active agents and yields a high impact fragrance “burst” upon blow drying the hair, ironing the fabric, or other types of heat treatment. The controlled delivery system of the present invention is a nano-sphere, having an average sphere diameter of from about 0.01 microns to about 10 microns. The nano-sphere comprises hydrophobic materials, cationic conditioning agent or, cationic conditioning agent in conjunction with a cationic charge booster to assist in adhering the spheres onto hair, skin, and fabric. The invention further relates to a controlled delivery system where the release rate of the active ingredients is synchronized with that of a sensory marker to convey to the consumer the product performance.

One embodiment of a trigger system with an integral selector for semi-automatic firearms. A selector allows the user to choose between two modes and rates of fire. A trigger (1) is made to allow passage of the lower portion of a selector cam (5) to the exterior of the firearm. A selector lever (6) is affixed to the lower end of the selector cam (5) on the exterior of the firearms action. Turning the selector lever (6) rotates the selector cam (5) which tilts a pivotal disconnector (3) on its axis, varying the amount of disconnector (3) engagement with a hammer (2). The variance in the disconnector (3) engagement causes the firearm to fire in one of two modes, firing one round with a trigger pull and resetting with trigger release, or firing one round with trigger pull, and firing another round with trigger release. Other embodiments are described.

Disclosed are methods and related compositions for altering the physical and chemical properties of a substrate used in hydrocarbon exploitation, such as in downhole drilling operations. In a preferred embodiment a method involves formulating a fluid, tailored to the specific drilling conditions, that contains one or more inactivated enzymes. Preferably the enzyme is inactivated by encapsulation in a pH responsive material. After the fluid has been introduced into the well bore, one or more triggering signals, such as a change in pH, is applied to the fluid that will activate or reactivate the inactivated enzyme, preferably by causing it to be released by the encapsulation material. The reactivated enzyme is capable of selectively acting upon a substrate located downhole to bring about the desired change in the chemical or physical properties of the substrate.

A preloadable trigger-release-clip that may be ceiling triggered for lighting module installation is described, including systems and methods of use. The trigger-release-clip may include a base-plate, a trigger, a clip, and a stop. The base-plate may be a structural member that attaches to a lighting module. The trigger may be in communication with the base-plate. The clip, with a torsion-spring, may be in communication with the base-plate. The stop may be in communication with the trigger.

A device for the rapid injection of a biological into the skin of a person. The device comprisies a hand-held applicator and a tape cassette adapted to be inserted into the applicator prior to use. The cassette houses a transportable tape having multiple doses of a biological disposed on a plurality of discrete clusters of microneedles affixed to the tape. In operation, a cassette is inserted into the applicator and a discrete cluster of microneedles advanced to a position adjacent a delivery opening in the applicator. A trigger advances the microneedle cluster to project outwardly through the delivery opening. The applicator is then pressed against the skin to force the cluster of microneedles into the skin. The applicator further includes means for applying an electric field between the microneedles and the skin to electrophoretically assist penetation of the biological into the skin. When the device is retracted from the skin and the trigger released, the next discrete cluster of biological-laden microneedles is advanced to underlie the delivery opening via a stepping tape transport means. The device may be used by relatively unskilled personnel to rapidly and painlessly vaccinate a large number of people.

A method for the encapsulation and triggered-release of water-soluble or water-dispersible materials.

An archery release aid for drawing the string of a bow using a substantially rigid cuff mounted on an archer's upper arm above the elbow comprising a substantially rigid cuff, a strap to transmit pulling force, and a means for attaching said archery release aid to known bow-string arrow trigger release devices. This archery release aid increases pull-force by relying on strength from the archer's upper arm and back instead of the lower arm and hand, and increases stability and shot accuracy by freeing the archer's hand and wrist from tension during release. Moving the point of pull above the elbow provides better leverage to the archer that allows him to pull a bow more easily or to pull a stronger bow than he would otherwise be able to pull. As the wrist is freed from tension the archer is better able to control release of the trigger, resulting in better consistency and accuracy of arrow placement.
