G09F 1902

US Classification:

362260, 362 84, 362322, 362282, 362806

Abstract:

A black light display device is provided which utilizes a black light source in combination with fluorescent/phosphorescent display elements which can be thread, strings, monofilaments, disks or sculptured material. The display elements are formed about a spindle which is secure by fixed in a housing which houses the black light source and the fluorescent/phosphorescent elements. One form of housing comprises selectively removable transparent barrier which is transparent to the visible light radiating from the fluorescent display elements but opaque to the ultraviolet light radiating from the black light illumination source.

Appl. No.:

10/874060

Inventors:

Peter Stephens - San Francisco CA, US

International Classification:

A63B069/00

US Classification:

473613000

Abstract:

A levitated finned ball device includes a ball made of a lightweight material and a base that generates laminar air flow to levitate the ball in mid-air. The ball has at least one generally semi-circular shaped fin extending therefrom. When the laminar air flow strikes the fin, it imparts motion to the ball.

Appl. No.:

6/245306

Inventors:

Peter H. Stephens - San Francisco CA

International Classification:

B43L 1300

US Classification:

33 18R

Abstract:

A drawing tool comprises a pair of transparent screens each defining a drawing surface on the underside thereof. A powderized etching composition is contained in a closed and sealed chamber beneath each drawing surface to fully coat the surface upon shaking of the drawing tool. An operator-controlled joy stick can be manipulated universally to simultaneously move drawing points along the drawing surfaces to scribe nearly identical two-dimensional designs thereon. An optical viewer mounted upon the screens enables the operator to stereoscopically view the individual images created by the designs as a three-dimensional image.

Inventors:

Peter H. Stephens - San Francisco CA

International Classification:

B43L 1300

US Classification:

33 18R

Abstract:

A drawing tool comprises a pair of light transmitting screens, a ground beneath each screen, and a former or tip under each screen adapted to either add material to the ground or subtract material from the ground to create a design thereon. The designs are viewed as a composite three-dimensional image and can be permanently fixed on a removable plate.
