Patents by Inventor Ulrich M. Fritzler

Ulrich M. Fritzler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4126386
    Abstract: An optical scanner system such as a projector for the continuous transmission of images to provide image immobilization is provided. The optical scanner system includes an illumination system, a scanner mechanism, and a projection lens system. The scanner mechanism is capable of creating virtual images of successive film frames with at least one virtual image point of each film frame positioned on a stationary locus point and at least another virtual image point offset from the stationary image locus point and relatively movable during a scanning movement. The scanner mechanism can, for example, be of a reflective or refractive polygon geometry. The specific parameters of the projection lens system and illumination system recognizes the inherent limitations of the dynamic keystoning aberration in scanner assemblies and seeks to nullify its effect in the projected real image. The projection means is of a telecentric design.

  • Patent number: 4113367
    Abstract: The present invention provides a multifaceted reflecting polygon scanner system that is suitable for incorporation into a projector, camera, or other optical scanning or image immobilizing apparatus. The rotating reflecting optical system of the present invention, is capable of being combined with a continuous film transport to produce an overlap frame dissolve of sequential frames for optical immobilization of a projected image. The present invention includes a primary roof reflecting polygon, a secondary reflecting polygon, and an image surface. By proper choice of the polygon parameters and their juxtaposition relative to the image surface, the present invention uniquely provides a significantly higher relative aperture with minimal kinetic aberrations such as dynamic keystone distortion and minimal static aberrations. In one embodiment, a pair of roof reflectors of a 60.degree. and 90.degree.
