Abstract: A traffic sign cover including a planar member having a first and second side and shaped to be place on a side of an existing sign. Holding members project from the sides of the planar member and optionally along a portion of the outer edges. The holding member and first side form a first slot therebetween for receiving and retaining the existing sign. The second holding member and second side form a second slot therebetween for receiving and retaining a temporary sign. The planar member is slideable upon the existing sign until a top receiving feature contacts a top edge of the existing sign, overlaying a side of the existing sign with the planar member. The temporary sign is slideable upon the planar member until a bottom edge contacts a bottom receiving feature of the planar member, overlaying and covering a side of the planar member with a temporary sign.

Abstract: A test method that helps identify foods that may be causing a reaction in an individual involves the individual entering into a computer a daily log of all the foods they routinely eat and any reactions that they may experience. The reactions may be headaches, fatigue, physical pain, depression, etc. The test method can be done without the individual having to follow any prescribed diet. After recording several weeks or months of data, the computer analyzes the data to determine if any significant mathematical correlations exist between a reaction and any of the foods, whereby a high positive correlation may suggest that the food is perhaps related to the reaction. In addition to food items, the method can analyze the correlation of other influencing agents such as environmental exposures, inhalants, menses, and stress.
