Abstract: An adaptive training system for use with an adaptive testing tool includes a user interface receptive of a field of application selection from a user. A plurality of task items are stored in a data store. The plurality of task items are organized by field of application and ranked by difficulty level. An adaptive item selector selects unfamiliar task items as training items based on the selected field of application and a user ability. These training items range in order of difficulty from items slightly below a user's ability to items sufficiently far above that level to allow for learning effects. The user ability is a function of previous user performance on an adaptive test in the selected field of application. The main purpose of the adaptive item selector is to ensure that training items are neither too easy nor too difficult for a person.

Abstract: A top-loaded dusting bag for dispensing powdered insecticide upon contact with the bag. The bag includes an inner porous sack made of burlap or other loose weave material and an outer skirt made of a non-porous material which covers the top and sides of the inner bag and extends below the bottom of the inner bag, leaving the bottom of the inner bag exposed only from underneath. In a first embodiment, a rigid support member secured to one side of the opening and a cantilevered U-shaped member secured to an opposing side of the opening form an assembly which in a first position exposes and separates the opening sides to form a funnel and in a second position, wherein the U-shaped member is rotated around the support member, folds the opposing side over the one side of the opening to close the opening.

Abstract: Apparatus and methods for thin film formation from which structures may be constructed for use in space. An elastic expandable torus is rolled upon itself about its circular axis as a bubble is formed so that the bubble attachment line may be repositioned to maintain an optimal ratio of attachment diameter to bubble diameter and to maintain an appropriate bubble contact angle and to provide a pre-wetted surface for the bubble at the bubble attachment line. Also included is a frame composed of memory metal which is compacted for immersion in thin film forming fluid and heated to its transition temperature for self erecting to a predetermined thin film shape whereby the need for pressurized gas for formation of the thin film is eliminated.
