Abstract: An aid for teaching mathematical concepts looks like a multiplication table but has separable rows of numbers. In the first row, cardinal numbers 1-n are displayed and second-N rows have cardinal numbers 2-n displayed along side one edge on the face. The remainder of the rows have the multiplication products of the cardinal numbers on the first row and the cardinal numbers of the rest of the rows arranged at the intersections of the cardinal numbers at the top and along side the edge. The rows are separable so they may be arranged in a multiplicity of pairs of fractional equivalents.

Abstract: Medical training kits and methods include a simulated liquid blood which simulates mammalian whole blood and a simulated hemostatic component. The simulated liquid blood includes a gellable component, and a simulated hemostatic component includes a gelling agent. The gelling agent causes the gellable component in the simulated liquid blood to form a mass of semi-solid or solid material in response the simulated blood being brought into contact therewith to thereby simulate blood clotting. In certain embodiments, the gellable component is chitosan and/or an alginate compound and the gelling agent is at least one compound which causes the gellable component to desolubulize, polymerize, complex, precipitate, cross-link and the like so as to form a semi-solid or solid mass of chitosan in response to physical contact between the simulated blood and the simulated hemostatic agent.

Abstract: A system and method of communication based on the Reverse Multiple-Choice Method of teaching and testing is disclosed where at least one communicant is a machine. The method is applicable for training a machine for knowledge engineering and artificial intelligence oriented applications, as well as for a trained machine to assist a human being engaged in the activity of teaching or testing.

Abstract: A multi-layer user-selectable electronic testing (MUSET) system provides a cascaded set of alternative testing formats for test-takers to select a testing format that best accommodates their level of ability. Test-takers can answer fill-in-the-blank (FITB) items on a computer or other input device. If the test-taker is less confident of their understanding, they can select multiple-choice (MC) or true/false (T/F) testing formats. The MUSET system measures, tracks, and stores the amount of time it takes to answer test items, to switch testing formats, and to change answers. Test-takers indicate a confidence level that they have in the correctness of their answer. The MUSET system determines confidence characteristics, latency characteristics, and hesitancy characteristics of the test-taker and gathers additional parameters to build a performance profile of the test-taker's skills/traits/abilities.

Abstract: A synthetic tissue model using one or more semi-flexible polymers or resin with at least one embedded mesh material is provided herein. The model provides suitable simulation of animal tissue designed to mimic tissue stiffness through varying the polymerization to simulate tissue stiffness level. Multiple polymers or multiple layers of polymer possessing different polymerization levels can be used to simulate tissues with different layers, such as skin. A mesh incorporated in the model provides durability, and can simulate layers of tissue through selection of the mesh material. A skin model using silicone-like material with a nylon tulle mesh was used to simulate skin for surgical procedures. The nylon tulle mesh increased resistance to tearing over time, due to insertion of surgical tools, thereby increasing usable life of the model and enhancing training as the model simulated skin for longer periods of time.

Abstract: A process for dry flower craft includes cutting craft media (dry botanicals with stencils) and mounting the same on any surface or product in combination with other botanical elements like bamboo, grass, weeds, seed, stem, tendrils, fiber, sola wood in any desired manner including an artistic manner. The process includes reducing color loss while drying and storage of vegetation and also during crafting of the vegetation, making stencils of cheapest materials such as cardboard and paper, cutting out motifs, shaping petals in any desired shape, and pasting the same with known adhesives. The botanicals are dried prior to floral collage decoupage by drying while using a mixture of desiccant of silica gel+silversand+non iodized salts (1:1:1 ratio). Finally obtaining floral decoupage or only floral collage or a combination of both in design processing as application of the craft, by making the floral resin laminates by reducing the peroxide harder by 1%.

Abstract: A device for visual and tactile learning in mathematics. A set is comprised of twenty-two individual clear, square counters; eleven male (11) and eleven female (12), each set numbered respectively zero through ten. Raised numbers, and dots provide a learning platform for number recognition and counting. Raised addition and equals symbols provide a platform for learning addition and subtraction. Addition can be achieved by drawing the two counters together in a locking process. Subtraction can be achieved by stacking and locking the female counter (12) over the male counter (11).

Abstract: A training door for breaching tools has a frame on which the door is hung by hinges at a hinge edge, while at an opposite edge being retained to a jamb by one or more non-shearing bolts. When the door is forced by a breaching tool at the bolt location, the jamb is forced laterally away from the door edge, against rubber mounts that allow limited jamb movement. As the door is forced in (or out, depending on its swing direction), with the jamb spread away somewhat the bolt will bend and fail pulling out of its socket. Replaceable sleeves are secured to the door edge, in several sections of the door to avoid breach tool damage on the door itself.
