A Selected-area Ultraviolet Disinfection (SUD) system which enables increased frequency of ultraviolet light treatment of spaces by improving the convenience, cost, safety, and/or efficacy. The core utility of the SUD system is to frequently and safely disinfect spaces where occupants are conducting their normal activities, enabled by a system constructed with a disinfecting light source that can direct and irradiate only selected areas (and corresponding volumes) that sensing and control components have determined are safe to disinfect, i.e. are not currently occupied.

A system includes one or more occupancy sensors, one or more environmental sensors and one or more controllable building components. A controller is configured to receive occupancy signals from the one or more occupancy sensors over a building network and to receive indoor air quality parameter signals from the one or more environmental sensors over the building network and to process the received signals to determine whether action is needed to improve one or more environmental conditions within at least some of the plurality of building spaces to reduce the likelihood of disease transmission among occupants of the building. Responsive to determining that action is needed, the controller is configured to provide control signals to one or more of the controllable building components over the building network to improve one or more environmental conditions within at least some of the plurality of building spaces.

An air fed mycoplasma device includes an array of elongate microchannels formed in a plastic or ceramic having tolerance to ozone and other radicals formed when plasma is generated from air in the microchannels. The microchannels include inlets configured to accept an air feed, and outlets configured to direct plasma jets toward a surface (which may be flat or internal to a pipe, for example) or object. An array of electrodes within the plastic/ceramic housing is configured to ignite and maintain plasma in the microchannels and is isolated by the dielectric from the microchannels. A supply intake for is configured to providing a plasma medium into the microchannels.

The present invention relates to a water-soluble effervescent solid perfume comprising a high content of fragrance which does not include organic solvents such as surfactants, preservatives, and alcohols. In addition, additional components may be carried for cleaning and sterilizing effects, and the effects of fragrance, cleaning, sterilization, and the like may be increased by impartation of an effervescent property. Furthermore, there is no generation of residual by-products after effervescent, and may be processed into a solid formulation, thereby improving stability and improving portability and convenience of use.

The invention relates to a disinfection method to be used for cleaning. The invention is characterized in that hydrogen peroxide (H.sub.2O.sub.2) is drained/transferred from one or more tanks (16) by a liquid pressure created by one or more pumps or gravity, through one or more draining pipes (6) to one or more draining devices (5), which draining device (5) drains hydrogen peroxide to one or more onto one or more evaporation top surfaces (4ea) of an evaporation member (4e) of a warming/heating device (4), the evaporation top surface (4ea) is at an evaporation angle (4ej) of 1 to 30 degrees in relation to the horizontal plane so that the end on the draining device (5) side draining end (4c) is higher than a gas discharge end (4d) at the opposite end of the draining device (5) of the warming/heating device (4), whereby hydrogen peroxide spreads by gravity on the evaporation

Embodiments of the present invention provide a method, system and assembly each adapted for enabling an imaging element cleaning apparatus to be placed through an abdominal wall of the patient without the use of a trocar or cannula. By eliminating the need for and use of a cannular or trocar, such embodiments advantageously overcome dimensional compatibility issues exhibited between the inside diameter of the central passage of commercially-available trocars and cannulas and the outside diameter of the sheath of an imaging element cleaning apparatus comprising such a sheath. Such dimensional compatibility issues are overcome by enabling an imaging element cleaning apparatus of the present disclosures to be placed through the abdominal wall of a patient without the use of a trocar or cannula. As a result, the sheath of the aforementioned imaging element cleaning apparatus can be in direct contact with the abdominal wall tissue.

An apparatus includes a conical body defining a chamber configured to contain a liquid and having a nozzle located a front end of the conical body and configured to discharge a stream of the liquid, a rear wall positioned at a rear of the conical body and at least partially defining the chamber, an inlet in communication with the chamber for introducing the liquid into the chamber, an acoustic transducer positioned at the rear wall, the acoustic transducer configured to generate acoustic energy and to introduce the acoustic energy into the liquid contained in the chamber, and an exhaust system including a vent in communication with the chamber to remove a mixture of liquid and gas bubbles from the chamber, an exhaust leading away from the vent, and an outlet in communication with the exhaust and configured to discharge the liquid and gas bubbles into or adjacent to the stream.

A hand-held personal hygiene device includes a main body having an upper end, a lower end, and a pump therein. The pump is configured to pump water or another fluid from an inlet port at the upper end to an outlet port at the lower end. A reservoir has a lower base configured to removably seat in the upper end of the main body to engage and open a self-closing valve with the inlet port of the main body. A tubular nozzle member has a lower end comprising one or more nozzle outlets and an upper end configured to be removably secured to the outlet port of the main body causing liquid pumped by the pump to flow through the tubular nozzle member to the one or more nozzle outlets. The reservoir and the main body may be aligned to form a liquid flow path that may be held vertically to allow gravity flow from the reservoir to the pump.

A furniture cleaning management system (FCMS) for a furniture affordance includes an indicator for indicating a state of the furniture affordance, a sensor option generating a signal indicating that the furniture affordance has been cleaned, and a processor receiving the trigger signal from the sensor option and causing the indicator to indicate that the furniture affordance is a cleaned state. The state of the furniture affordance indicated by the indicator may be selected from the cleaned state and a needs cleaning state. The processor may cause the indicator to indicate that the furniture affordance is in the needs cleaning state according to a schedule of furniture affordance occupancy, a schedule of furniture affordance cleaning, or as a consequence of sensing a user occupancy state at the furniture affordance.

A disinfectant and sanitizer canister system is disclosed. The system may include a pre-pressurized canister being pre-filled with one or more liquid cleaners and one or more propellants. The system may further include a valve sub-system including a dispensing valve and a valve control mechanism. The control mechanism may be configured to regulate the pressure of the pre-pressurized canister to cause the pre-pressurized canister to release the one or more liquid cleaners. The system may further include a dispensing sub-system configured to fluidically couple the pre-pressurized canister to the valve sub-system. The dispensing sub-system may include a dispensing member configured to dispense the one or more liquid cleaners contained within the pressurized canister. The system may further include a metering device, the metering device configured to provide a predetermined amount of pressure to dispense a predetermined metered dose of the one or more liquid cleaners.
