Title: Application of multi-media technology to psychological and educational assessment tools
Inventor: HERSH MICHAEL
IPC: A61B5/16
Filed: 1997-03-27
Abstract: Multi-media technology is applied to the testing of children, brain damaged adults and the general population using standard psychological and educational assessment tools. To avoid the inherent bias occurring when a tester (5) speaks in a language or dialect not fully comprehended by the student or other human subject (4), the multi-media computer (17) has a linguistic adaptation means, such as a sound card and data associated therewith, which can produce sounds, such as test instructions, in the most appropriate language and dialect of the test taker, such as a student, so that the human tester can provide the human subject with instructions for responding to the psychological evaluation. The human subject is exposed to computer-generated multi-media psychological evaluation probing, so that the human subject can respond to the computer-generated psychological evaluation probing. The computer tallies and records the student's responses and analyzes the human subject's recorded responses. Afterward the computer automatically prepares a report based upon the human subject's recorded responses, and transfers its report, such as transfer to a computer-readable diskette or by printing to a printer.

Title: Nanocomposites of dendritic polymers
Inventor: TOMALIA DONALD A
IPC: C08K3/00
Filed: 1998-01-13
Abstract: In the present invention, an inorganic reactant is, or reactants are, localized with respect to a dendritic polymer by physical constraint within or by a non-covalent conjugation to the dendritic polymer. The localized inorganic reactant or reactants is/are subsequently transformed to form a reaction product which is immobilized with respect to the dendritic polymer. This immobilization occurs on a nanoscopic scale as a consequence of the combined effects of structural, chemical and physical changes without having covalent bonds between the product(s) and the dendritic container and results in new compositions of matter called dendritic nanocomposites. The resulting nanocomposite material can be used to produce revolutionary products such as water soluble elemental metals, with specific applications including magnetic resonance imaging, catalytic, magnetic, optical, photolytic and electroactive applications.
