Appl. No.:

10/730083

Inventors:

David M. Sanders - Austin TX, US

International Classification:

A61B013/00

Abstract:

The infant eye trainer is a device that is mountable on a baby bottle for strengthening and developing infant eyesight. The device utilizes interchangeable media producing an image on a display, which may be viewed by the infant while drinking from the bottle. A variety of images designed to improve, strengthen, and facilitate infant eyesight development, both physically and cognitively are selected for display. The device mounts onto the end of a baby bottle, thus placing it within an infant's focal range. The device may also utilize audiovisual stimuli to further develop infant eyesight and cognition.

Abstract:

The present invention includes a polymer formed by the thermal rearrangement of an ortho-functional polyimide synthesized via chemical imidization with permeation properties for gas separation membranes higher than those synthesized via thermal imidization and a method for forming that polymer having tailored transport properties and different chemical resistance. The present invention also includes a polymer formed by the thermal rearrangement of an ortho-functional polyimide in which a portion of the ortho-position functional group is lost during thermal rearrangement to yield a thermally rearranged polymer with higher permeability than would be seen without the ortho-position group. This ortho-position group can be the result of chemical imidization, or the result of a post-imidization modification reaction.
