Illustrative processes remove ice buildup in containers or other locations by melting the ice using a de-ice component. Waste fluid may be removed using a vacuum component. The de-ice component causes discharge of pressurized fluid to melt ice. The de-ice component may include a base with guide features configured to engage an opening of the container. The de-ice component may direct a spray of the pressurized fluid into the container to melt the ice. The de-ice component may include a pressure regulator valve to selectively regulate a resulting force of the fluid sprayed into the container, which may enable a user to avoid damaging internal components located within the container. The vacuum component may cause the pressurized fluid to flow through a high pressure nozzle to create a vacuum effect at a suction inlet, which can extract waste fluid and/or other debris from the container.

Methods, devices and systems are described for digitally creating new scents or digitally dispensing gas, vapor, or liquid substances. A device includes a container or replaceable cartridge including one or more chambers containing one or more scented substances; a housing structured to include a compartment to hold the cartridge, an opening to allow the one or more scented or unscented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to deliver a scented substance from the corresponding chamber to the opening for delivering a scent from the one or more scented substances; and an actuator switch arranged in a corresponding transporting channel and rapidly operable to move between an open position and closed position based on an applied signal to selectively allow passage of the scented or unscented substance from the corresponding transporting path.

A compact hot air gun comprising a body, an air blowing pump, an air outlet tube, and a heating coil. The air blowing pump is disposed in the body. The air outlet tube has an end connected to the air blowing pump and another end extending beyond the body. The heating coil is disposed in the another end of the air outlet tube opposite to the air blowing pump. The compact hot air gun can generate an ignition effect by using hot air through the above structure.

Various examples are provided related to low pressure delivery, e.g., less than 250 psi at the point of application, of plural component system from unpressurized parts A and B material supplies. In one example, a system includes a polyurethane spray foam (“SPF”) raw material supply including parts A and B and a fluid handling system that can deliver the SPF raw material at low pressure to a metal spray gun in metered amounts through separate material fluid paths/conduits via a heated hose length and a whip hose. The fluid handling system can also deliver air at low pressure to the spray gun through separate air stream paths so that the air is communicated to the part A and B material conduits forward of the part A and B material input locations, where they are supplied separately to a mixing nozzle that is engaged at an end of the spray gun.

The manufacturing of footwear includes the joining of components. The joining may be accomplished with adhesive. The adhesive, such as a polyurethane, is applied as a single-sided adhesive to a footwear component. The application of the adhesive can contaminate the system that is applying the adhesive with intentional over spray of the footwear component. The over spray ensures adequate coverage of the footwear component to allow a sufficient bond. A masking platform of the system masks portions of the system to limit the contamination caused by the over spray. Additionally, material brushes and scrapers may engage with components of the system to remove or limit adhesive contamination on those components. A vision system maps a surface of the footwear component to ensure the adhesive is applied for the specific article.

A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.

A multi-axis mechanism device includes: a base module, a first moving module, a second moving module, a third moving module, a reaction module, a tilting module and a rotating module. The first moving module performs a first axial movement relative to the movable bearing platform to drive the reaction module to be displaced relative to the movable bearing platform. The second moving module performs a second axial movement relative to the first moving module to drive the reaction module to be displaced relative to the first moving module. The third moving module drives the movable bearing platform to perform a third axial movement relative to the module body to drive the reaction module to be displaced relative to the module body. The reaction module is driven by the tilting module to perform titling action and by the rotating module to perform rotating operation relative to the central axis.
