US Patent:

40079791, Feb 15, 1977

Filed:

Apr 18, 1975

Appl. No.:

5/569480

Inventors:

David B. Coblitz - Hazelwood MO

Assignee:

McDonnell Douglas Corporation - St. Louis MO

International Classification:

G02B 2710

US Classification:

350156

Abstract:

A device which eliminates unwanted light rays and permits passage of desired light rays. For the purposes of this specification, the desired light rays are those which originate on a first side of a material capable of effecting light passage, and which pass through the material to a second side. Undesirable light rays are those originating on the second side of the material, which pass through the material to the second side of the material. The material, in the embodiment illustrated, is a beam splitter intended to present a desired scene to an observer. The preferred embodiment includes a linear polarizer and a quarter wave retarder which impart an elliptical polarization to the undesired light rays. The polarizer and the retarder are arranged with respect to one another and to the beam splitter so that undesired light passing through the polarizer, retarder, and the beam splitter, and which is reflected back through the beam splitter to the polarizer will return, after reflection, with the same ellipticity but with orthogonal orientation. A method for determining the ratio components of light polarization when light is transmitted through a material, reflected and returned through the same material.

US Patent:

48336343, May 23, 1989

Filed:

Apr 2, 1986

Appl. No.:

6/847222

Inventors:

David B. Coblitz - Burke VA

International Classification:

G06F 1531

US Classification:

36472419

Abstract:

This rate dependent filter has a two-portion continuous filter function which optimizes noise filtering and minimizes detrimental lag or degradation characteristics. A first portion of the filter provides high filtering for low signal inputs below a first signal value. A second portion of the filter provides for a monotonically changing filter characteristic above the first signal values. The filter is especially useful in non-continuous transmissions, as radio, telephone, musical or other acoustical communication. It may also readily be applied to digital data transmission.
