A device for improving children's attention to urination includes a streamlined shell; a light module including a liquid sensor and a control unit and a plurality of light sources, the liquid sensor and the control unit and the plurality of light sources are connected one-by-one, the liquid sensor and the light sources are mounted on the surface of the streamlined shell, the control unit is mounted inside the streamlined shell; a power supply module mounted in the streamlined shell and used for supplying power to the light module. It can effectively increase children's attention to urination, keep children focusing on urinating in the liquid draining tray for lighting up more light sources or making sound. It can effectively prevent children from spilling urine out of the potty.

An automatic door handle/panel sanitizer dispensing assembly comprising a frame, a control unit including a processor, an actuator assembly controlled by the processor, the actuator assembly includes one of a pump and a valve, a first sensor operatively connected to the processor, a power storage unit powering the control unit, the actuator assembly, and the first sensor, a first nozzle and a second nozzle, both fluidly connected to the actuator assembly, a container coupled to the frame, for storing disinfectant, a threaded hook to hang the assembly onto the door handle, a tray having an arcuate shape and being arranged abutting a roof of the frame and being supported by the frame, a plurality of threaded tray holes extending through the tray arranged proximate to a rear end of the tray.

A system for systematically disinfecting shopping carts and other items includes an arch through which shopping carts or other items may be passed and disinfected. For disinfecting, carts are pushed through a passageway defined by the arch while nozzles positioned in the arch are actuated to dispense a disinfecting fluid. A fine mist of disinfecting fluid envelopes all surfaces of the cart as it passes through the passageway, thereby sanitizing the entire surface area of the cart with a reduction or elimination of residue accumulation. When spraying is deactivated, at least one solenoid is controlled to depressurize the tubing connected to the nozzles.

An array of non-thermal plasma emitters is controlled to emit plasma based on application of an electric current at desired frequencies and a controlled power level. A power supply for an array controller includes a transformer that operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user. The controller monitors reflected power characteristics, such as harmonics of the alternating current, to determine initiation voltage of the plasma and/or resonant frequency plasma emitters. The array of non-thermal plasma emitters may be used in therapeutic, diagnostic, and/or medical sanitization applications, including where a non-thermal plasma treatment regimen is prescribed.

A portable sanitizing arrangement is disclosed comprising essentially a protective case for a mobile productivity device such as a smartphone together with an ultraviolet light source for convenient disinfecting of high-touch objects and surfaces. The arrangement further comprises user controls and interfaces to enable the ultraviolet light source to safely emit light at wavelengths known to kill and destroy bacterial and viral species among other potentially harmful microorganisms. The sanitizing arrangement may irradiate the mobile productivity device itself as well as commonly encountered objects and surfaces in work, travel, entertainment and home environments with substantially greater ease and convenience and at potentially lower cost than with known sanitizing devices and methods.

The present disclosure includes, systems, devices, and methods for sterilizing objects, such as gaming equipment or gaming pieces. Some aspects include a sterilization device configured to be integrate with, or coupled to, gaming equipment to sterilize a plurality of gaming pieces. The device may include a housing defining a chamber configured to receive a plurality of gaming pieces and one or more light source(s) coupled to the housing and configured to emit ultraviolet (UV) light toward the gaming pieces.

A method for removing or preventing a microbial growth, biofilm, biomass and/or mineral deposit on a hard surface inside an SO.sub.2 scrubber is disclosed. In particular, biocide compositions may be dosed in pulse or continuously for the reduction and prevention of biofilms on the hard surfaces inside an SO.sub.2 scrubber. A biocide composition disclosed here uses one or more non-oxidizing biocides, especially a mixture of one or more quaternary ammonium compounds and one or more other biocides.

In some examples, a sanitization device includes an elongated member, a plurality of sanitizing sources located on a surface of the elongated member, and an attachment mechanism coupled to the elongated member, where the attachment mechanism is to couple the elongated member to an electronic device including a display.

A system and method for safe decontamination of a vehicle cabin while passengers can be present are disclosed that uses and/or has at least one data storage, at least one processor, at least one infrared (“IR”) sensor, and at least one ultraviolet (“UV”) emitter having a beam steering module. At least one contaminated area in the vehicle cabin is tracked using IR sensor data from the IR sensor. It is determined if there's a direct line of sight between the UV emitter and the at least one contaminated area. If so, UV emitter is activated to target the at least one contaminated area and blocking UV illumination on non-contaminated areas of the vehicle cabin and areas temporarily covered by a passenger.

A sterilization device includes: a reservoir, a supply port, an output port and a light source. The reservoir part includes a first half reservoir part having a substantially hemispherical shape and located on an upstream side in a flow direction of the fluid at the supply port, and a second half reservoir part having a substantially hemispherical shape and located on a downstream side in the flow direction. The supply port opens to the first half reservoir part. The output port opens to the second half reservoir part. When the supply port and the output port are projected on a virtual plane orthogonal to an extending direction of an inner surface of a supply channel connected to the reservoir part at the supply port, a center of gravity of the supply port and a center of gravity of the output port are separated from each other.
