A volatile composition dispenser and methods of detecting the replacement of a cartridge of volatile composition are provided. The cartridge of the volatile composition dispenser includes one or more reservoirs, with each reservoir containing a volatile composition. A method of volatilizing the volatile composition includes operating the evaporative assistance elements with varying energy over a total emission program. Replacement of the cartridge by a user when the volatile composition dispenser is disconnected from an external power source is detected in order to reset the total emission program when reconnected to the external power source.

A diffuser includes an adjustable heater having a temperature control knob providing indicia coordinated with like indicia on packets of vaporizable materials of different tendencies to vaporize. By manipulating the temperature control knob to the indicia corresponding to the indicia on the packet, a suitable quantity of energy is delivered to the diffuser resulting in suitable vaporization. One indicia is color coded packets and similarly color coded markings adjacent the temperature control knob.

Disclosed are methods and apparatus for disinfecting an interior space in a vehicle such as an aircraft. A method includes determining critical levels of heated air in the interior space of the vehicle required to neutralize effects of at least one predetermined pathogen, providing an apparatus for supplying heated air and positioning the apparatus in the interior space, activating the apparatus to supply the heated air to achieve the determined critical levels of the heated air in the interior space of the vehicle, maintaining the achieved critical levels of the heated air in the interior space for a determined critical time period, and optionally cooling the interior space following completion of the disinfecting process. A disinfecting apparatus may include a heated air generator, blower, controller and optional humidity generator, and may be implemented as a cart for traversing an aisle.

A venting apparatus for a heat source is disclosed. The venting apparatus includes a venting housing structure comprising a plurality of exhaust apertures proximate to a heat collector, wherein the exhaust apertures vent into a chamber defined, in part, by a circumferential surface having a radial extent from the apertures, and a thermoelectric device in thermal communication to the heat collector on a second surface thereof.

An apparatus and method for reducing scent emanating from a substantially enclosed structure such as a hunting blind. A fan in a fluid conduit draws odor-laden air from the internal environment and passes it through an ozone-rich vicinity provided for example by one or more ozone generators, then exhausts the treated deodorized air to the external environment. Fresh air is introduced into the negative-pressure enclosure from the external environment through one or more gaps or cervices in the structure.

Provided are an indoor unit of an air conditioner and a method for controlling the same, the air conditioner includes a humidification module to generate steam, mix the generated steam with filtered air to generate humidified air, and spray the humidified air at a discharge outlet through an independent flow path to provide the humidified air to an indoor space, in a smart care mode, performs a humidification operation during a heating operation to discharge the humidified air together with heat-exchanged air, automatically switches a mode between a high speed mode and a comfortable mode to prevent frequent on and off, thereby saving energy, and automatically switches an operation mode thereof according to a temperature and humidity to control discharged air and the humidified air, thereby effectively supplying air with adjusted temperature and humidity.

A ventilator system includes a gas flow chamber configured to receive ventilation gas circulating in a ventilation gas pathway of the ventilator and at least one UVC lamp. The UVC lamp is configured to radiate UVC spectrum light into the gas flow chamber to inactivate pathogens in the ventilation gas. A flow sensor is configured to measure a gas flow rate of the ventilation gas and a controller is configured to receive the gas flow rate, determine an intensity based on the gas flow rate, and control power to the UVC lamp based on the intensity.

A microfluidic delivery device is provided. The microfluidic delivery device includes a housing electrically connectable with a power source. A cartridge is releasably connectable with the housing. The cartridge has a reservoir for containing a fluid composition and microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in an upward direction relative to horizontal. The microfluidic delivery device also includes a fan that is connected with the housing. The fan is configured to generate air flow that converges with and redirects the fluid composition dispensed from the microfluidic die in a first direction to a second direction that is different from the first direction.

The smart electric incense and perfume burner is a remotely controllable, electrical incense burner controllable via a smart system using Wi-Fi or Bluetooth. The burner is in the form of an orb or spherical shell, which may be placed on top of a pedestal having a battery charging circuit. The orb functions separately as a portable, battery-operated, smart electric incense and perfume burner. The orb includes an upper chamber, centrally located at the top of the orb for liquid incense or perfume. The orb also includes a lower chamber with a solid incense heater. The outer surface of the orb has a plurality of vent openings for allowing smoke from the upper and lower chambers to exit the interior of the orb. The vent openings are surrounded by multicolor LEDs and are adapted to receive elongated decorations for display.

An electronic scented candle is described that includes a movable flame-shaped component, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber and a scent chamber. An electric fan is positioned within the shell to drive the air into the scent chamber and a scent outlet coupled to the scent chamber to allow the fragrance material to leave the scent chamber and to reach an external environment of the electronic scented candle. The electronic candle also includes a receptacle for connecting a power cord on a bottom surface of the electronic candle. The bottom surface includes a plurality of protruding stands that provide a space to allow the power cord to be connected to the receptacle and be routed below the bottom surface.
