Abstract: The invention provides a dispensing composition for the controlled release of semiochemicals, such as pheromones, wherein the semiochemical is enclosed in a network of a crosslinked polymer which is substantially free of radical initiator residues. The dispensing composition can be prepared by mixing a prepolymer with the semiochemical and optional additives and crosslinking the mixture by means of gamma radiation or electron beam treatment, or by UV radiation or heat in the presence of a radical initiator, the residues of which are subsequently extracted. The prepolymer is preferably an acrylate or methacrylate terminated prepolymer. The rate of release of the semiochemical can be varied by modifying the network density, the type of prepolymers, the degree of loading and the shape of the dispenser. Vulnerable semiochemicals can be stabilized by adding stabilizers, such as UV absorbers and antioxidants. The predetermined release rate can be sustained for several months. The composition can be shaped or applied as a coating.

Abstract: An articulating hand stamp mechanism is disclosed which is capable of being articulated between closed and open positions. In the closed position, a pair of pivotally connected split housings (12,14) enclose the stamp pad (21) and its housing (16) completely. The mechanism may be articulated open by causing the housings to rotate about the pivot point which in turn results in the stamp pad housing to rotate to a horizontal position so that the pad can be brought against an article to be marked. Each of the split housings has had grasping portions (18,20) with one of the hand grasping portions having a pressure bearing surface (20) canted at an angle with respect to the other portion when the mechanism is closed. Because the pressure surfaces are canted and positioned a distance away from the pivot point, increased torque is provided, allowing the mechanism to be easily opened when desired while simultaneously minimizing opening caused by unintentionally applied forces.

Abstract: Methods of forming a numerical control program for a machine tool, computer animation, animal training, human skill development, robot programming and sport motion development. 
     The methods involve constructing a human/animal body model, applying actual human/animal movements to it and analysing the input movements using inverse dynamics. Further desired movements are then calculated using dynamics on the various segments of the body independently of one another, then applying known constraints governing the actual possible motion of each segment, and then analysing the corrected motion again using inverse dynamics.
