Abstract: According to the embodiment, a toilet seat device includes a toilet seat and a biological sensor. The toilet seat that is formed of a resin material and includes a seating part on which a user is seated, and a bottom surface part facing the seating part. The biological sensor that is of an optical type, is positioned inside the toilet seat, and detects biological information of the user seated on the seating part. The seating part includes a thick portion and a thin portion. The thin portion is thinner than the thick portion. The biological sensor is located at a back surface side of the thin portion. The thick portion and the thin portion are formed as a continuous body. The thin portion has a thickness that can transmit irradiated light irradiated from the biological sensor and reflected light reflected from the user seated on the seating part.

Abstract: A toilet system includes: a toilet seat having a seat surface on which a user is to sit; a sensor provided in or on the toilet seat, configured to measure a physical quantity which reflects blood flow conditions of the user; a health index calculator configured to calculate a health index of the user based on measurement results of the sensor; a health index output part configured to output the health index of the user which has been calculated by the health index calculator; a temperature determining part configured to determine whether a temperature state of the seat surface satisfies a predetermined condition or not, and an operation change instruction part configured to change an operation of the health index calculator and/or an operation of the health index output part when the temperature determining part determines that the temperature state of the seat surface satisfies the predetermined condition.

Abstract: There is provided a water area equipment that can inhibit water scale formation and further can very easily remove formed water scale. In the water area equipment, silicic acid polymerization can be inhibited to reduce water scale formation, and, further, formed water scale can very easily be removed, for example, by lightly wiping off the water scale. The water area equipment on which water from a water supply source can be poured comprises a unit configured to add an inhibitor for silicic acid polymerization to water deposited as water residual on the surface of the water area equipment and can inhibit water scale formation and can allow formed water scale to be easily removed. A specific unit that inhibits the polymerization of silicic acid is configured to enhance the acidity of water and, for example, to adjust pH of residual water to 1.5 to 5.5.
