ABSTRACT:
An alcoholic concentration indicator comprising three superposed circular discs adapted to rotate about a common axis. The lower disc displays on its margin a scale of alcohol concentration indicia and over its central surface a multiplicity of numbers representing the number of drinks consumed. The middle disc has a series of aperture across a diameter to provide usual access to the numbers appearing on the central portion of the first disc. Each aperture is identified by a weight of a human body. A scale of consecutive numbers also appears to represent the number of hours elapsed since the first drink. The top disc is transparent and displays two pointers: one pointer for the alcoholic indicia and the other pointer for the time elapsed since the first drink. The desired results are obtained by visualizing the number corresponding to the number of drinks through the aperture corresponding to the weight of the user. Then one pointer of the transparent disc is aligned with the number corresponding to the number of hours elapsed since the first drink. The other pointer become automatically aligned with the estimated alcoholic concentration in the user's blood.
