Abstract: A system and method for permitting user access to a computer controlled device. A display device displays a group of items to the user. Some of the items are known to the user and some are unknown to the user. An input device receives user input from the user. The user input indicates the presence or absence of the known items within the group of items without specifically identifying which items are known and which items are unknown. A computer is programmed to automatically compare the user input to a predetermined answer. If the user input is correct an access device allows access. In one preferred embodiment the user input includes a count of the number of known items within the group of items. In another preferred embodiment the group of items includes subgroups. The user input includes an identification of which subgroup has the largest number of known items. In another preferred embodiment the group of items is displayed in a grid. The known items are displayed in a pattern within the grid.

Abstract: This invention is directed to a system and method for selecting composition components or composition formulations for manufacturing plastics or other articles according to desirable selection criteria. This invention includes a computer readable medium containing a set of computer readable instructions and a components database where the set of computer readable instructions allows for receiving selection criteria, comparing the selection criteria with the database information, selecting composition components or composition formulations within a predetermined range of the selection criteria and displaying the selected components or formulations on a color correct monitor so that the user can view the search results without having to view actual physical samples.
