US Patent:

49438514, Jul 24, 1990

Filed:

Mar 7, 1989

Appl. No.:

7/320289

Inventors:

Paul W. Lang - Orange CA
Franklin C. Gribshaw - Orange CA

Assignee:

Gold Stake - Pasadena CA

International Classification:

H04N 916

US Classification:

358 87

Abstract:

A viewing system is provided for presenting a projected image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the viewing system, can view the projected image simultaneously. The 360. degree. viewing system features an optical system which rotates with respect to a cathode ray tube about the vertical axis in synchronization with the rotation of the projection screen. A liquid crystal display (LCD) screen is utilized to define a viewing window which is continuously redefined at sequential intervals to remain continually aligned with the projection screen.

International Classification:

H04N 916

US Classification:

358 64

Abstract:

A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates a black and white image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A liquid crystal display (LCD) screen is utilized to define a filtered viewing window which is continuously redefined at sequential intervals to remain continually aligned with the rotating real image in space. The LCD screen includes normally opaque red, green and blue filter panels which operate to give color to the real image in space.

Appl. No.:

6/832168

Inventors:

Paul W. Lang - Orange CA
Franklin C. Gribshaw - Orange CA

International Classification:

A24D 102
A24D 112

US Classification:

131365

Abstract:

A cigarette made of cut tobacco rolled in a paper having a refractory layer with a predetermined pattern bonded to or imprinted upon the interior surface of the paper. The pattern is formed outside of rows and columns of what eventually become elongated slots when the paper burns away. The slots are arranged in lengthwise rows and also are arranged in columns. Each row has a slot midpoint which lies midway between slots in each adjacent row.

International Classification:

H04M 954
H04M 100

US Classification:

178791

Abstract:

A picture in the form of a print or projected image onto a rear view screen in a suitable mounting is positioned in a vertical plane and the mounting then rotated extremely rapidly about a vertical axis exactly bisecting the picture in the plane. With this arrangement, each person in an audience surrounding the mounting over 360. degree. can view the picture each time the viewer's line of sight is normal to the plane of the picture so that, in effect, the entire audience regardless of their position over 360. degree. can view the single picture simultaneously.

Appl. No.:

6/185144

Inventors:

Paul W. Lang - Long Beach CA

International Classification:

G02B 2717

US Classification:

350 69

Abstract:

A laser beam is scanned in a circular pattern so that it will successively impinge upon light entrance ends of a plurality of optical fibers arranged in a similar circular array. Successive fibers differ in path lengths in such a manner that the light from the scanning laser beam exits substantially simultaneously from the exit ends of the fibers so that a relatively high intensity or amplitude light pulse results.

Appl. No.:

6/104186

Inventors:

Paul W. Lang - Orange CA

International Classification:

G02B 2714

US Classification:

350174

Abstract:

The assembly includes a plurality of individual pulse lasers arranged to be successively triggered at predetermined time intervals. A single light transmissive body receives the output pulses from the lasers at different input angles so that the respective pulses follow different path lengths in the body. The sequence of firing of the lasers and the respective angles are such that pulses exiting from the body will all exit substantially simultaneously. The result is a high energy concentration of output light.

International Classification:

US Classification:

Abstract:

An image rotating apparatus presents a projected video image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the apparatus, can view the projected video image simultaneously. The video image rotating apparatus utilizes light valve technology to create red, green and blue images from an analog composite video signal, and a Phillips prism that aligns the images produced by the light valves for projection through an optical system. The image produced by the light valves is rotated, either mechanically or electronically, in synchronization with rotation of the projection screen. The projection screen itself eliminates the need for a separate shutter by both expanding the projected image generally parallel to the screen's axis of rotation, and constricting the width of the projected image generally perpendicularly to the screen's axis of rotation.
