Patent number: 7156597Abstract: A dual bar code for detecting contamination. When no contamination is present, a first bar code identifies the product. When contamination is present a second bar code identifies the presence of contaminants.Type: GrantFiled: February 11, 2003Date of Patent: January 2, 2007Assignee: SIRA Technologies, Inc.Inventors: Robert M. Goldsmith, Catherine H. Goldsmith, James G. Woodaman

Patent number: 7157048Abstract: The present invention relates to a contamination detector associated with a double bar code that includes coded indicia used to identify the presence of conditions indicative of microbial contamination, including toxic contaminants, bacterial metabolites, and other microbial secretions. Of the two bar code symbols associated with the contamination detector, the first identifies the product or container, while the second bar code symbol is designed to identify the presence of contaminants. When contamination is not detected, the first bar code symbol is scanner readable, whereas the second bar code symbol is not. Once contamination is detected, bars in both bar code symbols can appear or disappear causing the first bar code symbol to become scanner unreadable and the second bar code symbol to become scanner readable.Type: GrantFiled: February 11, 2003Date of Patent: January 2, 2007Assignee: Sira Technologies, Inc.Inventors: Robert M. Goldsmith, Catherine H. Goldsmith, James G. Woodaman

Publication number: 20020072079Abstract: The present invention relates to a food contamination detector associated with a double bar code, given the trademark GILBAR™ by the owner of the present invention, that includes coded indicia used to identify the presence of conditions indicative of microbial contamination in food, including toxic contaminants, bacterial metabolites, and other microbial secretions. Of the two bar code symbols associated with the food contamination detector, the first identifies the food product in terms of the type of food, the quantity, the price and the like, while the second bar code symbol is designed to identify the presence of contaminants. When contamination is not detected, the first bar code symbol is scanner readable, whereas the second bar code symbol is not. Once contamination is detected, bars in both bar code symbols can appear or disappear causing the first bar code symbol to become scanner unreadable and the second bar code symbol to become scanner readable.Type: ApplicationFiled: August 10, 2001Publication date: June 13, 2002Applicant: Sira Technologies, Inc.Inventor: James G.

Patent number: 6190610Abstract: A food contamination detector. The food contamination detector comprises a first bar code symbol coded to identify a food product by a bar code reader, a second bar code symbol coded to identify contaminated food by a bar code reader, and an indicator printed onto a substrate which changes color when food is contaminated and causes the first bar code symbol to be unreadable by a bar code reader and causes the second bar code symbol to become readable by a bar code reader.Type: GrantFiled: July 12, 1999Date of Patent: February 20, 2001Assignee: California South Pacific InvestorsInventors: Robert M.
