International Classification:

A61K009/14

US Classification:

424/489000, 424/400000

Abstract:

A composition including (a) about 2 to about 25 wt % of L-ascorbic acid, (b) about 0.1 to about 10 wt % of at least one selected form the group consisting of cationic polymers and cationic surfactants, and (c) about 0.1 to about 70 wt % of at least one selected from the group consisting of humectants, polymers with humectant properties, and inorganic driers. The ratio of ingredient (a) to ingredient (b) is about 1:1 to about 50:1. The composition is stable when stored at room temperature for a period of at least ten weeks.

International Classification:

G06K 9/00

US Classification:

382117

Abstract:

Various systems, processes, and techniques may be used to achieve biometric identification via retina scanning. In some implementations, systems, processes, and techniques may include the ability to scan a retina using a scanning laser ophthalmoscope to acquire at least one retina image, analyze the image to identify retina blood vessels, and identify a plurality of branch points of the retina blood vessels. The systems processes, and techniques may also include the ability to calculate a data set that represents the identified branch points, compare the calculated data set representing the branch points against at least one pre-stored data set representing retina branch points, and determine whether the calculated data set corresponds to the pre-stored data set.
