Abstract: The present disclosure relates generally to systems and method for testing and determining corrective lens prescription for a patient. In an example embodiment, a system includes a hand-portable first electronic device, a second electronic device with a computerized screen, and a server to conduct a vision test for a person. The vision test includes determining, an axis prescription, a cylinder prescription, and a sphere prescription for each eye of the person. A corrective lens prescription is provided for the person based, at least in part, on the determined axis, cylinder, and sphere prescription for each eye of the person.

Abstract: A support assembly for a computer input device includes a generally C-shaped slide member mountable to the underside of a desk surface for slidingly receiving a vertical column member. Notches formed in the column member are engaged by teeth of a collar portion of a support arm. The arm is thereby adjustable to various vertical positions on the column. A computer keyboard or mouse pad may thereby by supported on the arm with both height adjustability and the ability to be retractable beneath the desk surface. Where the assembly is used to support a keyboard, a slide arm supporting the keyboard may be provided with ribs engaging slots of the support arm. By configuring the support arm with an S-shaped side elevation, movement of the slide arm on the support will allow the keyboard to tilt through a negative angle permitting the keyboard operator to adjust the angle of tilt to a comfortable neutral tilt position.

Abstract: A paper guiding system for an acoustic printer enclosure which includes universally adjustable paper guides which slidably extend into the interior of the printer enclosure to direct printer paper across the gap formed between the paper transport system of a printer housed in the enclosure and the paper opening in a panel of the acoustic printer enclosure.

Abstract: A printer stand comprising spaced right and left supports. Each support is a unitary plastic molding which includes an elongated wide support member having a flat upper support surface. Central and rear paper passageway notches are open at the inner edge of the member and a reinforcing rib extends along the underside of the member and across the notches. Leg means support the member above a base surface on which the stand rests, for storage of paper beneath the printer and feeding of that paper into the printer through one or more of the notches in the support members. Pads are provided on the support surfaces to cushion the printer.
