A dispensing device, comprising a plurality of microfluidic pumps, microfluidic valves, and a microfluidic mixer chip, for receiving and mixing microfluidic amounts of a plurality of fluids having differing viscosities, is disclosed. The device includes a plurality of pathways for moving fluids from associated reservoirs to the microfluidic mixer chip. A mix controller controls the microfluidic pumps and valves so that the fluids, having different viscosities, can be accurately mixed at specified microfluidic amounts or volumes according to a specified microfluidic recipe, and the microfluidic mixture dispensed from the device. The device can be in communication with a software application implemented on a mobile compute device, such as a smartphone, and receive instructions for implementing the specified microfluidic recipe from the software application such that the operation of device components is at the direction of the software application executed on the mobile compute device.

An immiscible droplet generation system may include a chip, a microfluidic channel integrated into the chip, an input to the microfluidic channel through which the microfluidic channel is to be filled with a first fluid that is to be moved through the microfluidic channel and a droplet generator. The droplet generator is integrated into the chip to generate a droplet of a second fluid, immiscible within the first fluid, and to inject the droplet into the first fluid in the microfluidic channel.

The present invention relates to a spraying assembly comprising an injection device, a first hydraulic circuit for conveying carrier liquid to a spray nozzle, the first hydraulic circuit comprising, upstream of the spray nozzle, an injection section, a second hydraulic circuit for conveying the active substance to the injection device, under an injection pressure greater than the carrier liquid circulation pressure, the injection device comprising a direct dosing interface comprising a plurality of through-holes in the injection section of the first hydraulic circuit, and the injection device further comprising at least one corresponding actuator configured to open or close each through-hole so as to allow a determined dosing of active substance to pass through at least one open hole to be injected into the carrier liquid stream.

The personal water enhancement device disclosed herein is designed for removing particulates and impurities from a volume of water and then adding a preferred combination of vitamins and minerals to such volume of water. In a preferred embodiment, the device may comprise a water purifier and filter, a user interface, a database of water formulations, a container for storing salts, and a mechanism for dispensing salts into water. Such a device may allow a user to add a pre-set or customized concentration of various salts and minerals to said volume of water as per their unique needs, and may further reduce both the environmental burden of plastic bottle production and the financial burden of bottled water consumption.
