A method for operating a fragrancing device, wherein a blower device is provided which sucks air through an air inlet opening into the first air duct and conveys it to an air outlet opening. At second air duct is provided, which branches off from the first air duct at a first duct branch and rejoins the first air duct at a second duct branch. A first fragrance container is provided in the second air duct between the first duct branch and the second duct branch, which can be flowed through by the air flow in the second air duct. A first valve device is provided upstream and/or downstream and controls the flow through the first fragrance container. The blower is controlled in such a manner that a defined, substantially constant, air flow is generated as a sum through the first air duct and the second air duct.

An energized air freshening apparatuses comprising perfume mixtures having an olfactive index and vapor pressure distribution for improved diffusion into a space methods thereof are provided. The energized air freshening apparatus may include a delivery engine containing the volatile perfume mixture, a fluid transport member, and an evaporation assistance element such as a fan that is configured to move a volume of air over the fluid transport member to facilitate evaporation of the perfume mixture into the atmosphere.

Systems and methods for detecting presence of a thing, the thing treated with a descenter, one method including in an area in which it is possible that a thing treated with a descenter is present, using a detector to detect a descenter level in the area, producing a detected descenter level, comparing the detected descenter level to a normal descenter level for the area, determining that the detected descenter level is different from the normal descenter level, said determining indicating the possible presence of a thing treated with a descenter; and using a trained service animal to facilitate such a method.

Technologies are generally described for apparatuses and methods relating to a mobile device holder and air freshener. The mobile device holder and air freshener may include a body, a fastening component, a removable cap, a flexible arm, and a mount. The fastening component may secure a mobile electronic device to the apparatus. The removable cap may allow scented material to be installed within the body. The fastening component may secure a mobile electronic device to the apparatus. The flexible arm may be coupled to the body at a first side and the mount on a second side. The mount and the flexible arm may support the mobile electronic device. The body may allow air that has entered the apparatus through a first vent of the apparatus to become scented and flow out of the apparatus through a second vent of the apparatus.

A sanitizing device for a vehicle (20) which, when in use, is adapted to deliver chemical agents and/or gases for sanitizing the interior of a vehicle (10). Additionally, the sanitizing device (20) integrally comprises a pressure sensor (30) adapted to monitor the pressure inside the vehicle (10) when the sanitizing device (20) is in use. In particular, when the door (11) is opened, the sensor (30) detects a pressure gradient, thus interrupting the delivery of the chemical agents and/or gases inside the vehicle (10).

An airflow fan accessory comprising an accessory having a scented fabric and a fastening mechanism located along the outer edge of the scented fabric. In a preferred embodiment, the accessory may be easily attached to and detached from the fan blade enclosure of any typical airflow fan. Upon air flow through the fan and airflow fan accessory, a pleasant scent may be imparted to the room via release of scent from the scented fabric component.

A ventilation system for removal of aerosols including bacteria and viruses such as the COVID-19 Coronavirus, and airborne debris from dental/medical operatories is provided. This ventilation system is comprised of (1) a stationary hood, secured at a specific distance above a patient that pulls contaminated air from the operatory, (2) ducting that carries the contaminated air away from the operatory, (3) a UV Ozonator that treats the air and cleans it of viral and bacterial aerosols and airborne debris before (4) expelling it to the outside through a specified length of terminal duct. The combination of certain embodiments in this invention create an effective means of aerosol and airborne debris removal in dental/medical operatories or other indoor spaces.

The present invention is directed to a digital aroma system that provides a scented air on demand to various devices in various forms and user held devices including: remote controls, video game controllers and mobile computing devices. Dry fragrance infused substrates are contained in fragrance cartridges that are removably mounted in a cassette that is connected to a manifold that has airway passages that are connected to fans or pumps that are controlled by a computer processor. In response to a fragrance control signal or a fragrance trigger, the processor can selectively direct scented air having a specified fragrance to a system user.

An air disinfection device includes: a housing that includes an inlet port for taking air therethrough and a disinfection chamber that has a shell in a shape of a truncated ellipsoid. The device also includes: a disinfection head that is disposed in the inlet port and includes a light source for generating disinfection light that disinfects the air in the disinfection chamber, where the light source is located substantially on a plane where a first focal point of the truncated ellipsoid is located. The disinfection head further includes a fan for taking the air through the inlet port to the disinfection chamber and a filter for filtering the air. The device further includes a power source electrically coupled to the disinfection head and configured to provide electrical power for the disinfection head.

An orientation independent delivery device. The delivery device includes a gas chamber, a delivery chamber, a gas cell, and a delivery aperture. The gas chamber includes a gas-side rigid portion and a gas-side flexible barrier. The gas-side flexible barrier is sealed to the gas-side rigid portion. The delivery chamber includes a delivery-side rigid portion and a delivery-side flexible barrier. The delivery-side flexible barrier is sealed to the delivery-side rigid portion and is oriented adjacent to the gas-side flexible barrier. The gas cell is coupled to the gas-side rigid portion of the gas chamber. The gas cell increases a gas pressure within the gas chamber to expand the gas-side flexible barrier. Expansion of the gas-side flexible barrier applies a compressive force to the delivery-side flexible barrier allowing a delivery material to escape from the delivery chamber.
