Title: Application of multi-media technology to psychological and educational assessment tools
Inventor: HERSH MICHAEL
IPC: G09B7/02
Filed: 1997-03-27
Granted: 2010-07-27
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.

Granted: 2002-01-08
Abstract: A generator 101 produces randomly an integer A, which satisfies 0~ A<(P1-1)(P2-1)~~~(Pm-1), in synchronism with a clock pulse applied via an input terminal 180, where each of P1, P2, ~~~Pm is a prime number equal to or more than 2. First calculating means 4 calculates an integer X, whose probability of being a prime number is high, using the integer A based on equation X= a1(P1P2 Pm/P1)B1 + a2(P1P2~~~Pm/P2)B2 + ~~~ + am(P1P2~~~Pm/Pm)Bm(mod P1P2~~~Pm). In this case, a k (k=1, 2, ...,m) is an integer which satisfies congruence equation a k(P1P2~~~ P m/P k)=1 (mod P k), while B k represents {A mod (P k-1)} + 1. An adder 107 outputs the integer X as an integer with a predetermined number of bits.

Abstract: Methods and compositions are provided for the treatment and repair of defects in the cartilage or bone of humans and other animals as in full-thickness defects in joints. To induce cartilage formation, a defect in cartilage is filled with a matrix having pores sufficiently large to allow cartilage repair cells to populate the matrix. The matrix contains an anti-angiogenic agent that serves as a functional barrier to prevent vascularization and bone growth into the cartilage area. The matrix filling the defect in cartilage may also contain a proliferation agent and a chemotactic agent, and a transforming factor in an appropriate delivery system. A functional barrier between the bone and cartilage areas of a full-thickness defect may also be created by heat-treating the areas of bleeding to form a transient tissue barrier which prevents blood vessels and associated cells from penetrating from the bone area into the cartilage area. If desired, the bone portion of the full-thickness defect may be filled with a matrix having pores large enough to allow cells to populate the matrix and to form blood vessels. The matrix filling the bone defect may contain an angiogenic factor and an osteogenic factor in an appropriate delivery system. Methods and compositions are also provided for assisted bone and connective tissue regeneration for dental and other applications.
