Title: Means and method for demonstrating the effects of low cyclinder astigmatism correction
Inventor: HAWKE RYAN
IPC: A61B3/036
Filed: 2014-03-13
Granted: 2023-08-29
Abstract: A method for demonstrating the benefits of correcting blurred vision involves presenting an image to a patient, the image comprising a scene composed of one or more of textual and non-textual elements having one or more of the following properties, including facial recognition and expressions, high frequency detail, gratings and text, rotating gratings, array of gratings, text in motion, text in perspective, text with distraction and high contrast patterns. The elements are designed so as to provide an improved assessment of vision correction. Individuals may be comfortable with a certain amount of blur caused by astigmatism as the brain adapts to this blur making it more difficult to have an eye chart that leverages the perceptual aspects of vision. Each of the elements provide a significant change when viewed with and without vision correction to the extent that the difference may be binary (i.e. elements are invisible without correction).

Abstract: Hydrogels that degrade under appropriate conditions of pH and temperature by virtue of crosslinking compounds that cleave through an elimination reaction are described. The hydrogels may be used for delivery of various agents, such as pharmaceuticals. This invention provides hydrogels that degrade to smaller, soluble components in a non-enzymatic process upon exposure to physiological conditions and to methods to prepare them. The hydrogels are prepared from crosslinking agents that undergo elimination reactions under physiological conditions, thus cleaving the crosslinking agent from the backbone of the hydrogel. The invention also relates to the crosslinking agents themselves and intermediates in forming the hydro gels of the invention. The biodegradable hydro gels prepared according to the methods of the invention may be of use in diverse fields, including biomedical engineering, absorbent materials, and as carriers for drug delivery.

Inventor: DIXIT SURJIT B
IPC: G16B15/00
Filed: 2013-08-16
Granted: 2021-06-29
Abstract: Systems and methods for searching conformation space of a polymer to determine a three-dimensional conformation of the polymer that satisfies a performance metric is provided. The polymer comprises a plurality of domains and at least a first hinge. Initial three-dimensional coordinates of the polymer are altered by pivoting the first domain with respect to the second domain about the first hinge thereby obtaining an altered set of three-dimensional coordinates for the polymer. In this altering, atoms within the first domain are held fixed with respect to each other and atoms within the second domain are also held fixed with respect to each other. The altered set of coordinates is scored against a performance metric. Additional instances of the altering and scoring are performed, if necessary, until the altered set of three-dimensional coordinates satisfy the performance metric.
