  • Patent number: 8571671
    Abstract: A critical element of a retinal prosthesis is the stimulating electrode array, which is placed in close proximity to the retina. It is via this interface that a retinal prosthesis electrically stimulates nerve cells to produce the perception of light. The impedance load seen by the current driver consists of the tissue resistance and the complex electrode impedance. The results show that the tissue resistance of the retina is significantly greater than that of the vitreous humor in the eye. Circuit models of the electrode-retina interface are used to parameterize the different contributors to the overall impedance.

  • Patent number: 4932871
    Abstract: A method for preparing chromogenic .alpha.-amylase substrate compounds at substantially high preparative yields in a relatively short period of time by the transglucosylation of a chromogenic glucoside compound to a maltooligosaccharide chain. The concentration of the maltooligosaccharide compound is greater than about 3 times the concentration of the chromogenic glucoside compound to result in at least about 50% of the chromogenic glucoside compound being converted to the desired chromogenic .alpha.-amylase substrate compound.
