摘要： A toilet comprising a rinsing seat, a rimless bowl, and a helical loop trapway is disclosed. An annular cavity for the purpose of storing and dispensing rinse water from the rinsing seat is disclosed. Outlet nozzles arranged about the circumference of the rinsing seat and designed to dispense rinse water at the rimless bowl are disclosed. Rinsing seat supports, hinge assemblies, and seat sensors which offer additional functionality to the rinsing seat are also disclosed. The toilet includes a steep interior surface with a titanium dioxide coating and actuatable ultraviolet light sources. The titanium dioxide has antimicrobial properties in the presence of ultraviolet light to sanitize the toilet. The ultraviolet light source is actuatable to control when the antimicrobial properties of the titanium dioxide coating are activated. The exterior of the toilet is coated with doped titanium dioxide which is antimicrobial in the presence of visible light.

摘要： The antimicrobial toilet includes one or more pairs of electrodes positioned below a water line when the hydraulic circuit is at equilibrium. The pairs of electrodes may be connected to a power source by electrical wires. In some embodiments, the electrodes are positioned on the inner wall of the toilet bowl and in some embodiments, the electrodes are positioned within the siphon tube. In some embodiments, the electrodes are metal strips and in others they are circular. When actuated, an electrical current passes through the toilet water between the electrode pairs resulting in disinfected water. Some embodiments include a pump and water conduit which transfers disinfected water to areas above the water line and emits the water to wash areas of the toilet.

摘要： We disclose a method of tagging pharmaceutical and nutritional products with nanoparticles which include noble metals. The disclosure describes a plurality of nanoparticles each with either a different size and/or shape. The nanoparticles of different sizes and shapes are distinguishable using spectroscopic techniques because each is associated with different optical properties and have a different spectral signature. The different optical properties are at least due to the unique size or shape of the nanoparticles. Each of the plurality of nanoparticles may be associated with a different characteristic of the tagged pharmaceutical or nutritional product. The method includes mixing the nanoparticles with or adhering the nanoparticles to the tagged pharmaceutical or nutritional product. Two or more of the plurality of nanoparticles may be mixed with or adhered to the tagged pharmaceutical or nutritional product in a ratio and the ratio may be associated with a characteristic of the product.
