Filed:

May 8, 1987

Appl. No.:

7/048100

Inventors:

James L. Faulkerson - Woodside CA
Raymond L. Picard - Scotts Valley CA
Edward J. Menard - Sunnyvale CA
Sanford M. Bennett - Mountain View CA
Timothy J. McCarthy - San Jose CA

Assignee:

Everex Ti Corporation - Fremont CA

International Classification:

G06K 936

US Classification:

382 56

Abstract:

An adaptive image acquisition system employing a hand-held optical scanner or camera is disclosed. The system includes an adaptive camera exposure control system to adjust the camera exposure time to the media's reflectivity characteristics. The system assembles a "filmstrip" of images from compressed video data, wherein redundant image data appearing in successive image frames has been removed. The system employs a correlation process between successive frames to identify the redundant frame information and determined the camera velocity. By adapting the correlation process to the velocity of the camera, the effects of variations in the velocity may be substantially eliminated.

Appl. No.:

6/317802

Timothy W. McCarthy - Walnut Creek CA

Assignee:

Allied Corporation - Morris Township, Morris County NJ

International Classification:

C02F 158

US Classification:

210719

Abstract:

Trihalomethanes (THM's) in water, particularly in drinking water, are substantially reduced by treatment of the water with small amounts, i. e. , below about 50 ppm, of sulfite ion supplied by sodium metabisulfite or sulfur dioxide. The addition to the water of the sodium metabisulfite alters the structure of the THM's precursor and lowering the chlorine demand. The sulfite ion may be introduced prior to chlorination, or at an intermediate stage of the chlorination, or in adjunct with the chlorination which permits the use of substantially reduced amounts of chlorination.
