A modular antiviral air filter assembly for filtering displaced air in a toilet has a ventilated filter housing having a bottom sealing surface, a peripheral side wall, and a top lid, the filter housing fixed to or formed contiguously to the underside of the top lid of the toilet, at least one antiviral filter disposed within the filter housing having contact with the displaced air from the bowl of the waste collection utility. The antiviral filter assembly closes and seals against the donut rim seat after use and remains sealed during flush operation of the waste collection utility wherein the displaced air from water filling the collection bowl is filtered through the one or more antiviral filters before egress out of the ventilated portion or portions of the filter housing.

A solution for cleaning and/or sterilizing one or more surfaces in a bathroom is provided. The sterilization can be performed using ultraviolet sources, which can emit ultraviolet radiation directed onto the surface(s). The cleaning can be performed using a fluid, such as water, that is flowed over the surface(s). The surface(s) can include at least a seat of a toilet and/or other surfaces associated with the toilet.

The ventilated toilet seat is a toilet seat with built in ventilation holes and channels. Gases accumulating within a toilet basin are collected within the ventilation holes and channels and are routed to an exhaust duct. Ideally, the exhaust duct is vacated using a fan. The ventilated toilet seat comprises a toilet seat, a plurality of ventilation holes and channels, a first seat hinge, a second seat hinge, a first lid hinge, a second lid hinge, a main seat exhaust, a first exhaust tube, a second exhaust tube, an end cap, and an elbow joint.

Disclosed is a bioinstrumentation apparatus including a main unit, a detection portion, a light source, and an optics sensor. The bioinstrumentation apparatus is a kind of home health care device for testing Triglycerides automatically without requiring any chemical reagent or blood specimen.

A system for suppling water to a toilet through a hole located in the toilet. The hole may be the hole provided for securing the toilet seat to the toilet. The hole may be provided with a hollow fastener for both securing the toilet seat to the toilet and for supplying water to the toilet. The system may supply water from a source to a component of the toilet, such as a bidet seat or a toilet bowl cleaning seat.

A toilet that includes a tank configured to hold water from a water supply; a reservoir fluidly connected to the tank and configured to hold a cleaning compound comprising a chemical compound and water from the water supply; and an actuator configured to control a flush cycle of the toilet upon a first activation, the actuator including at least one nozzle fluidly connected to the reservoir and configured to discharge an amount of the cleaning compound external to the tank upon at least one of the first activation or a second activation.

A protective enhanced-maintenance antiviral coating for interior components of a passenger cabin is disclosed. In embodiments, the enhanced-maintenance antiviral coating incorporates into the antiviral coating indicating agents, e.g., reflective or fluorescent compounds that combine with the antiviral coating without otherwise impeding its antiviral and/or antibacterial properties. The enhanced-maintenance antiviral coating is applied to external surfaces of the interior components of an aircraft cabin or other mobile platform especially prone to frequent physical contact by multiple individuals. The indicating agent reacts via reflectivity and/or fluorescence when ultraviolet (UV) band or otherwise specialized lighting is applied to the external surfaces. A lack of reflectivity or fluorescence may be interpreted as significant wear or damage to the antiviral coating, for which corrective actions may be taken.

A toilet seat apparatus according to an embodiment includes: a toilet seat on which a user sits; a light emitting unit including a light emitting element that emits light; a light receiving unit including a light receiving element that receives light; and a control unit that controls energization of the light emitting element and application of voltage to the light receiving element, in which the control unit performs light reception control including transmitting a control instruction to open an electronic shutter to the light receiving element and energizing the light emitting element so as to permit reception of the reflected light from feces, and performs control of setting an interval from a start of execution of one light reception control to execution of light reception control subsequent to the one light reception control, to 0.2 milliseconds or more.

Toilet seat cleaning devices, methods and systems are described. Toilet seat cleaning systems may include a toilet, a toilet seat, a sensor, and a fluid dispenser. Toilet seats may include a flow way, at least one opening and at least one surface whereon fluids from a fluid dispenser may be communicated. Fluid dispensers may include a fluid container and a dispenser mechanism. Methods of using toilet seat cleaning systems may include a user influencing the activation of a dispenser mechanism; the dispenser mechanism influencing the communication of fluid from a fluid container to a flow way; the fluid being communicated through the flow way and out of at least one opening and onto at least one surface of a toilet seat; and the fluid on the at least one surface of the toilet seat being engaged by the user in order to clean the toilet seat.

A toilet that includes a tank configured to hold water from a water supply; a reservoir fluidly connected to the tank and configured to hold a cleaning compound comprising a chemical compound and water from the water supply; and an actuator configured to control a flush cycle of the toilet upon a first activation, the actuator including at least one nozzle fluidly connected to the reservoir and configured to discharge an amount of the cleaning compound external to the tank upon at least one of the first activation or a second activation.
