  • Patent number: 7507893
    Abstract: One embodiment of the present invention relates to a method for teaching music to one or more students. The instructor's manual operation of a musical instrument controls in real-time the illumination of guide lamps on each student's musical instrument. This allows the students to visually connect the note to be played with the instructor's verbal instruction and then play the visually indicated note without having to look up at the instructor or a distant display. In another embodiment, the instructor's manual operation of his musical instrument provides a score display of the played note on each student's musical instrument. The students can visually connect the played note with the musical notation on the score display. Remote teaching over a communication network is also described as well as a removable interface for the musical instrument to assist in teaching and use of the instrument.

  • Patent number: 7353693
    Abstract: In the evaluation apparatus of the present invention, there are formed a plurality of minute channels having a cross-sectional area of not more than 1 mm2, one end of each of these channels joins in at a single meeting point and, when liquids are put into one or more of the liquid reservoirs in a higher position over any other liquid reservoir, the liquids flow down in the channels by gravity. Therefore, a scientific phenomenon, such as the diffusion of molecules, can be qualitatively observed. Furthermore, the apparatus provides a sufficient level of accuracy to enable the user to watch various phenomena involved in advanced technology, and uses no large quantity of chemicals or the like, which means little load on the environment.

  • Patent number: 5197883
    Abstract: A sound-coded system for teaching beginning reading using four sound descriptors which allows one letter or digraph to represent each sound without altering the traditional orthography, or correct American English spelling, of the original words. The sound descriptors correspond to the long vowel sounds, the single-sound digraphs, the silent or misleading letters, and the sounds made with a slight throat utterance. The simplicity and reliability of sound-coding makes decoding of unfamiliar words a game for beginning readers. A particularly preferred method of use is in the context of a book wherein the opaque text pages are interleaved between transparent pages.
