Problems solved by technology

However, weight alone does not discriminate the relative amounts of urine and feces.
Liquid level meters or divided bowls which separately collect urine and feces and which are supported by independent strain gauges could work, but these require a total redesign of the toilet system and are not compatible with a retrofitted toilet.
The addition of feces to the bowl typically causes a rapid rise in the bowl liquid level or decrease in user weight.
However, some feces are small and not as easily distinguished.

Abstract

An in-toilet apparatus for discrimination of urine and feces is disclosed. An optical sensor is provided for the analysis of urination and defecation events within a toilet bowl. Additionally, strain gauges are provided to make possible the quantification of urine and feces that a user releases. The combination of data from the optical sensors and strain gauges makes it possible for a user to readily know the mass of their bodily excrements, characterized by excrement type. In several embodiments the optical sensor is a thermal camera mounted on the toilet seat or in the toilet bowl. In other embodiments the optical sensor is a water level sensor. In varying embodiments, strain gauges are located in the toilet seat or in an attached footscale or both.

Description

BACKGROUNDField of the Invention[0001]The present invention relates to the measurement and characterization of human excrement.Background of the Invention[0002]For management of various health conditions, it is useful to track the amount of urine and feces a user passes. It is possible to track the sum of urine and feces using change in weight. However, weight alone does not discriminate the relative amounts of urine and feces. Methods such as flammable gas sensing can detect the presence of flatus or feces but not the quantity. Flammable gas sensing is also somewhat slower. Liquid level meters or divided bowls which separately collect urine and feces and which are supported by independent strain gauges could work, but these require a total redesign of the toilet system and are not compatible with a retrofitted toilet.[0003]The addition of feces to the bowl typically causes a rapid rise in the bowl liquid level or decrease in user weight. On the other hand, the addition of urine add...
