A method of atomizing a fluid composition is provided that includes dynamically measuring the minimum-required actuation energy for the fluid composition. The method includes the steps of: connecting a microfluidic cartridge with a housing of a microfluidic device, the microfluidic cartridge comprising a reservoir containing the fluid composition and a microfluidic die in fluid communication with the reservoir; the microfluidic device comprising a controller; measuring the minimum-required actuation energy for the fluid composition at a first time; atomizing the fluid composition in a first atomization period; measuring the minimum-required actuation energy for a fluid composition at a second time that is after the first time; and atomizing the fluid composition in a second atomization period.

A microfluidic delivery device and method of dispensing a fluid composition from a microfluidic die are provided. The method includes generating air flow from a fan; directing a first portion of the air flow through a first air outlet in a housing; directing a second portion of the air flow through a second air outlet in the housing; jetting a fluid composition from a microfluidic die through a fluid orifice in the housing; directing the second portion of air flow adjacent to the microfluidic die and out the fluid outlet, wherein the first portion of the air flow directs the fluid composition jetted out of the fluid outlet into the air.

Apparatuses and methods are disclosed for deodorizing exhaled smoke or vapor. A tube may be provided for receiving a stream of exhaled air. An emitter coupled to the tube may be operable to emit a deodorizer chemical into the stream of exhaled air in the tube. A deodorizer chemical source may be coupled to the emitter for delivering the deodorizer chemical to the emitter.

A disinfecting unit and method of operating the same includes a cabinet having a vertical axis, a first lamp coupled to the cabinet directing light in a generally radial direction relative to the vertical axis, a second lamp coupled to the cabinet directing light in at least a partially axial direction relative to the vertical axis and a nebulizer that dispenses disinfecting fluid therethrough.

A microfluidic delivery device and method of dispensing a fluid composition from a microfluidic die are provided. The method includes generating air flow from a fan; directing a first portion of the air flow through a first air outlet in a housing; directing a second portion of the air flow through a second air outlet in the housing; jetting a fluid composition from a microfluidic die through a fluid orifice in the housing; directing the second portion of air flow adjacent to the microfluidic die and out the fluid outlet, wherein the first portion of the air flow directs the fluid composition jetted out of the fluid outlet into the air.

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.

The present invention relates generally developed safety portable incense heater and more particularly to a self-contained incense heater shaped a reversed (L) letter for safely holding, igniting and heating incense (bukhoor wood bricks). The developed safety portable incense heater shaped a reversed (L) letter is going to heat the incense (bukhoor wood bricks) with a certain temperature in order to help the user to direct the smoke flow in the exact direction of the nozzle using the fan thrust. The self-contained developed safety incense heater shaped a reversed (L) letter has a small as pocket size and is portable without any wires to enhance the mobility of the users and the way of using incense or bukhoor wood bricks.

A mosquito repeller includes a casing, a mosquito repellent liquid bottle, and a first heating element installed in the casing. The first heating element includes a first heat-generating body and a cotton swab. The first heat-generating body is inserted into the cotton swab, and an end of the cotton swab away from the first heat-generating body extends into the mosquito repellent liquid bottle. Since the first heat-generating body is inserted into the cotton swab, heat is concentrated at the center of the cotton swab, and the cotton swab is heated uniformly, and the vaporization of the mosquito repellent liquid is stable to improve the mosquito repelling effect of the mosquito repeller, while reducing the power consumption of the mosquito repeller, saving energy, avoiding a temperature rise of components near the heat-generating components, retarding the ageing of components, and extending the service life of the mosquito repeller.

A scent dispenser may comprise a vial retaining mechanism, a heating element, vial sensor, and a controller. The vial retaining mechanism includes a vial coupling that removeably retains a vial containing a scented solution. The includes a wick extending from a cavity of the vial through an opening of a neck of the vial. The heating element is shaped to receive and heat the wick of the vial. The vial sensor includes an array of sensor pads that are arranged in alignment with the vial retained by the vial coupling. The controller is electrically coupled to the heating element and electrically coupled to the array of sensor pads. The controller regulates a temperature level of the heating element, and receives signals from the array of sensor pads and processing the signals to determine a fluid level of the vial.
