An adult scale three-wheeled device facilitates movement for mobility challenged persons. The device is foot propelled while seated either through walking while seated or pedaling. The device is provided with a limited footprint for navigating confined areas while the individual is seated in a substantially standing position, with the pedals being repositionable so as to allow unobstructed walking while remaining seated. A lockable braking system prevents one or more wheels from turning. The device is collapsible for storage.

Orthopedic mobility device

An image-receiving element adapted to the provision of a diffusion transfer photograph and having a preprinted security pattern between contiguous layers thereof is disclosed. The pattern comprises a patterning agent and a binder therefor preferentially adhesive to the contiguous layer closest in proximity to the image-receiving layer of such element. Diffusion transfer photographs prepared from the image-receiving element carrying the preprinted security pattern are useful in the production of an information-bearing document such as an ID card.

Preprinted image-receiving elements for laminated documents

Laminar structures comprising a color diffusion transfer photographic print bonded to a vinyl sheet using an adhesive mixture of a vinyl acetate-ethylene copolymer and a hydroxylated polymer, and a method for preparation thereof using an adhesive-supporting carrier sheet.

ID Card laminar structures and a method for preparation thereof using a

A process for heat-stabilizing polymeric supports for diffusion transfer photographic image-receiving elements. Such treatment eliminates distortion effects in these image-receiving elements when they are exposed to high temperatures, such as encountered in ID card lamination devices.

Irradiation treatment of polymeric photographic film supports

Laminated documents such as I.D. cards using a light-transmissive pigment material as a verification or validation pattern.

Novel I.D. cards

Laminated documents such as I.D. cards using a phosphorescent material as a verification or validation pattern.
