Latest Patents

One of his latest inventions is the "Alpha-wave amplitude selector with window slicer." This device quickly selects and detects a time domain in which the amplitude of alpha components in brain waves exceeds or falls below given threshold levels for use in biofeedback. The combination of a window slicer that receives alpha waves as input and an RS flip-flop connected to the window slicer significantly reduces the time delay between the point at which the amplitude of the alpha wave exceeds or falls below a preset level and the point at which a feedback stimulus is given. The window slicer outputs a high pulse when the alpha wave exceeds a high threshold slice level and a window pulse when the alpha wave enters an intermediate region.

Another notable patent is the "Phosphate optical glass." This optical glass comprises P₂O₅ of 40-55 weight percent, R₂O of 20-40 weight percent, TiO₂ of 8-20 weight percent, and various other components. The specific composition allows for unique optical properties that can be utilized in various applications.
