  • Patent number: 7465299
    Abstract: In a laser eye treatment apparatus, a probe light source generates a secondary emitted light emanating from a treatment area of retinal tissue that is irradiated by a treatment light source. An optical detector detects the secondary emitted light. A processor statistically analyzes the secondary emitted light to determine a temperature of the treatment area of retinal tissue.

  • Patent number: 6704588
    Abstract: An apparatus (10) for determining a diagnostic glucose level in a human subject includes a light source (30) that produces collimated light at a selected wavelength. The collimated light is arranged such that it passes through a portion of an eye (12) of the subject and reflects off an eye lens (16) at a selected angle (&thgr;B) as reflected light. A polarization analyzer (70) measures a polarization of the reflected light that exits the eye (12). A path length processor (68) determines an optical path length (L&lgr;) of the reflected light within an aqueous humor (22) of the eye (12). A glucose level processor (90) computes a glucose concentration based on the measured polarization and the determined optical path length (L&lgr;).

  • Patent number: 6156335
    Abstract: The invention is represented by a transdermal medicated patch for the extended release of 17.beta.-estradiol to the skin. The transdermal patch is formed by an outer covering, a matrix containing from 1% to 5% (w/w) 17.beta.-estradiol, and a protective liner which is removed before use. The matrix is formed of pressure-sensitive adhesive acrylic copolymers, in which the active ingredient is dissolved or dispersed. The acrylic copolymers are obtained by radical copolymerization of 2-ethylhexyl acrylate, methyl acrylate, acrylic acid, vinyl acetate, hydroxyethyl acrylate or a mixture thereof. Optionally quantities of less than 0.5% (w/w) of other substances may be added.
