A nose-to-brain drug delivery device is provided. The nose-to-brain drug delivery device includes a freeze-dried drug container for storing a freeze-dried drug, a restoring solvent container for storing a solvent for thawing the freeze-dried drug, a membrane for preventing the freeze-dried drug from being mixed with the solvent, and a compressor for providing a driving force. The membrane is opened by the driving force of the compressor to mix the freeze-dried drug with the solvent, thereby thawing the freeze-dried drug, and the thawed drug is sprayed by the driving force of the compressor.

An aerial paint spraying vehicle includes a body and a paint reservoir removably coupled to the body and configured to store paint. The aerial paint spraying vehicle includes a pressure vessel removably coupled to the body and configured to pressurize the paint from the paint reservoir. The aerial paint spraying vehicle includes a paint applicator assembly configured to receive the pressurized paint and expel the pressurized paint through a spray nozzle towards a target surface.

A liquid dispensing system includes at least one container for storing the liquid to be dispensed, the at least one container having a neck defining a fill opening for the liquid. The system includes a liquid dispensing device releasably connectable to the at least one container, an exchangeable cartridge for an additive to be mixed with the stored liquid, where the cartridge is accommodated in the neck, and a piercing member for opening the cartridge. The cartridge includes a one-piece hollow body filled with the additive and with a pressurized gas, and the piercing member is arranged to pierce a wall of the hollow body. A method of dispensing a liquid by using the liquid dispensing system, and a cartridge for use in the liquid dispensing system and/or method.

This application relates to a cooling device that sprays a coolant received from a coolant reservoir toward a target region to cool the target region. In one aspect, the cooling device includes a spraying unit from which the coolant is sprayed, a valve configured to regulate a flow of the coolant, and a control unit configured to control opening and closing of the valve, wherein, when cooling starts. The control unit controls a first cooling mode in which a temperature of the target region is decreased and a second cooling mode in which the temperature of the target region is maintained in a predetermined temperature range to be sequentially performed.

A handheld portable spraying system includes a fluid source having a plurality of different fluids and a fluid container configured to separately contain the plurality of different fluids. The handheld portable spraying system also includes a fluid pathway configured to carry the plurality of different fluids from the fluid source through an outlet of the handheld portable spraying system, and a fluid conveyance system configured to cause the plurality of different fluids to flow along the fluid pathway. The handheld portable spraying system further includes a controller configured to generate a control signal to control the flow of the plurality of different fluids along the fluid pathway.

A fluid dispensing gun for 1K-polyurethane foam includes a dispensing tube with a dosing nozzle at its outlet, a spring-loaded needle co-axially moveable in the dispensing tube for opening and closing the dosing nozzle, a trigger actuating the needle to open the nozzle and to dispense the fluid, a regulator regulating the degree of opening of the nozzle outlet and a coupler coupling a pressurized can to the gun. It also concerns a method for dispensing 1K-polyurethane foam. The fluid dispensing gun includes a delivery device delivering a curing fluid essentially parallel to the nozzle outlet that includes a curing fluid reservoir, a curing fluid outlet situated near the nozzle and a curing fluid line connecting the curing fluid reservoir and the curing fluid outlet, the trigger activating the delivery device. The curing fluid delivered in the same direction as the 1K-polyurethane foam and separately therefrom makes the foam cure more rapidly.

The invention comprises an apparatus and/or a method of use thereof for dispensing whipped cream, comprising: a profi including a pressure containment housing, a first receiving port integrated into the pressure containment housing, a dispensing port integrated into the pressure containment housing, and at least a first pressure cartridge containing at least a liquid form of nitrous oxide, where the pressure cartridge includes a pressure gas delivery port and where a connection between the receiving port and the pressure gas delivery port form: (1) a section of a pressure containment unit encompassing contents of the pressure containment housing and the pressure cartridge and (2) an open path between the pressure containment housing and the pressure cartridge.

Provided is smart glasses including a spectacle frame having a lens frame to which a pair of lenses or a display is coupled and a pair of spectacle temples which extends from both ends of the lens frame in one direction; a cartridge detachably mounted on the spectacle frame and in which a functional material contained; a spray nozzle which is provided at a nose pad portion of the lens frame and discharges the functional material contained in the cartridge to an outside; and a supply path formed inside the spectacle frame to supply the functional material from the cartridge to the spray nozzle.

The invention comprises an apparatus and/or a method of use thereof for dispensing whipped cream, comprising: a profi including a pressure containment housing, a first receiving port integrated into the pressure containment housing, a dispensing port integrated into the pressure containment housing, and at least a first pressure cartridge containing at least a liquid form of nitrous oxide, where the pressure cartridge includes a pressure gas delivery port and where a connection between the receiving port and the pressure gas delivery port form: (1) a section of a pressure containment unit encompassing contents of the pressure containment housing and the pressure cartridge and (2) an open path between the pressure containment housing and the pressure cartridge.

A timber marking system includes a portable back pack mounted user, the pack carrying a paint storage tank and a pressurized gas tank. The storage tank is pressurized and coupled with a manually operated trigger to allow filed operated timber marking. A method to mark timber includes preparing the tank system with pressurized gas, selectively marking a preidentified tree at the trunk and stump.
