Title: Method for preventing eutrophication
Inventor: HORIUCHI ISAO
IPC: C02F1/54
Filed: 2002-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent eutrophication of stagnant water eutrophied by accumulation of nutritive salts. SOLUTION: In a method for preventing eutrophication of stagnant water, tannin or tannin acid is put in eutrophied stagnant water in which planktons grow to reduce the number of the planktons as well as to lower the concentrations of total phosphorus and ammoniacal nitrogen or nitrite nitrogen in the stagnant water or the COD of the stagnant water. By this simple operation, eutrophication of the stagnant water is prevented without adversely affecting nature, and the environment can be improved.

Title: Interpolation method for optical navigation system
Inventor: DIETZ ZACHARY
IPC: G06K9/64
Filed: 2002-07-25
Abstract: PROBLEM TO BE SOLVED: To reduce the size and complexity of an interpolation mechanism. SOLUTION: Interpolation along an axis is performed on a correlation surface array that is created by counting the instances of difference (XOR) between corresponding pixels of single bit resolution images having trial displacements. The interpolation is performed by finding the intersection of two straight line segments that are identified by the shape of the cross section of the correlation surface along the axis of interest. In nine trial shifts, there are three values in such a cross section. Their abscissas are the pixel shift amounts minus one, no shift and plus one and their ordinates are the corresponding correlation values. In situations where navigation (and interpolation) is possible, these three points have certain properties.  The usual case is that two of the points determine one line having a slope (m) and the other point determines the other line assumed to have slope -m. The intersection of the two lines is found and its abscissa is the interpolated value for motion along the axis of interest.
