A Mac Beth color checker chart automatic detection method is also provided.a testing unit that tests the flood-filled image to provide a modified flood-fill image, wherein a set of heuristic tests are employed to automatically determine quantity and location of Mac Beth color checker charts.
Some patent numbers, as displayed in the table, are 7 characters with the numeric portion padded with leading zeroes. Therefore, the number of patents granted during a year cannot be determined by simply subtracting the number of the first patent issued in one year from the number of the first patent issued in the next year.
The user should note that while the data in this table have been checked, it still is possible that inadvertent errors remain.
The following table displays the calendar year along with the first corresponding document number issued in each year for selected patent document types (utility, design, plant, and reissue patents and statutory invention registrations) (*) The current patent numbering system began with a patent issued on July 13, 1836.
Prior to that date, an estimated 9,957 patents had been issued.
I’m the current contact for information about historical Ball jars on the Ball Corporation web site.
One of the most common emails I receive comes with a description of a jar—e.g., Blue pint Perfect Mason with the number 5 on the bottom—and the question, “How old is my jar?This invention provides novel methods for the determining the birth dates or synthesis dates of biomolecules, organisms, cells, tissues and organs.Methods for determining the birth date of an organism by determining the birth date of a biomolecule of the organism are also provided....wherein the set of heuristic tests includes accepting a partition area in the flood-filled image that has a ratio of its partition area to the number of pixels contained therein that exceeds a selected minimum ratio.wherein the set of heuristic tests includes accepting partition areas in the flood-filled image that are clustered together and have substantially equal aspect ratios containing about a same number of pixels.Rejoice if you find one of those; Buffalo jars are pretty rare.
