The present invention relates to automatic odor treatment spray dispensers.

The present invention provides a discharge system for an aircraft, in which a remaining amount of an aerosol container can be displayed so that an exchange timing can be managed systematically. A discharge device for an aircraft, having an aerosol container and a discharge device for discharging contents from the aerosol container, wherein the discharge system discharges the contents of the aerosol container while the aerosol container is attached to the aircraft, includes remaining amount acquiring means for acquiring information indicating a remaining amount of the contents of the aerosol container, and display means for displaying the remaining amount in accordance with the remaining amount information acquired by the remaining amount acquiring means.

A device and method for diffusing volatile substances which obtains the energy required for the autonomous operation thereof from one or more photovoltaic cells. The activation periods and switch-on frequency of the emission means are determined adaptively by an electronic controller depending on the light conditions, thereby maximizing the time in which the device diffuses the volatile substance without compromising its autonomy.

The present invention provides an agent dispenser for use in introducing an agent into a fluid where the agent is miscible with such fluid. The agent dispenser comprises a hollow casing constructed of a material having a coefficient of cubical expansion that differs from the coefficient of cubical expansion of the fluid. At least one opening is provided in the hollow casing for permitting the flow of the fluid to and from the interior of the hollow casing. The opening is provided with a tube sealed in the opening, one end of the tube being contained within the hollow casing and the second end of the tube being exterior to the hollow casing for communication with the surrounding fluid. The second end of the tube is provided with a filter membrane having a defined pore size to prevent any debris which may be present in the fluid from blocking the second end or entering the hollow casing. The dispenser contains the agent and the agent is introduced into the fluid through fluid drawn into and expelled from said dispenser as a result of variations in the internal pressure of the dispenser resulting from thermal expansion and contraction of the dispenser and its contents caused by variations in the temperature of the fluid surrounding the dispenser.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

An animal behavior modification device is provided. The device includes a sound, vibration or motion sensor that is configured to generate electrical signals in response to an occurrence. The device may include a filter, which is tuned to recognize a dog barking event, and generate an electrical signal in response to recognizing an input signal indicative of a dog's bark. The device further includes a canister that holds a deterrent fluid under pressure. The device additionally comprises a motor module configured to rotate a shaft in response to the electrical signal from the filter. The canister has a spray nozzle for releasing fluid that affects the dog's senses. In response to rotating the shaft, the spray nozzle is depressed. A method of modifying the behavior of an animal using the device is also provided herein.

The disclosure concerns a device for dispensing an atomized spray of a cosmetic composition. The device is capable of individual or commercial use, and provides yaw and pitch actuation of an operational head, along with the atomized spray to deliver the cosmetic composition to the body of a user. Electronics are configured to acquire data from a disposable spray bottle assembly, and approximate remaining volume or spray time according to the data. A linear laser provides guidance to the user for standing in order to receive optimal spray coverage.
