The invention relates to a fluid reservoir (2) for an aerosol generator (50), the fluid reservoir (2) comprising a fluid chamber (4) for receiving a fluid (6), an opening (8) for guiding the fluid (6) received in the fluid chamber (4) outside the fluid chamber (4), and a collar portion (10) surrounding the opening (8) and extending into the fluid chamber (4). A first portion (12) of the fluid chamber (4) extends along the length of the collar portion (10) in a height direction (H) of the fluid chamber (4), A second portion (14) of the fluid chamber (4) is arranged adjacent to the first portion (12) in the height direction (H) of the fluid chamber (4). A lateral extension of the first portion (12) in the directions perpendicular to the height direction (H) of the fluid chamber (4) is smaller than a lateral extension of the second portion (14) in the directions perpendicular to the height direction (H) of the fluid chamber (4). Further, the invention relates to a fluid reservoir (2′) for an aerosol generator (50), the fluid reservoir (2′) comprising a fluid chamber (4′) for receiving a fluid (6′), an opening (8′) for guiding the fluid (6′) received in the fluid chamber (4′) outside the fluid chamber (4′), a recess (9) arranged at least partly below the opening (8!) in a height direction (H) of the fluid chamber (4′), and a cover member (30′) which releasably or permanently seals the recess (9). Moreover, the invention relates to an aerosol generator (50) comprising the fluid reservoir (2, 2′).

A motorized misting hair dye applicator for dispersing a dye mist throughout the hair of a user employs a comb body having a plurality of teeth which each include an ultrasonic atomizer nozzle integral therewith. The comb body additionally includes a dye distribution system which allows stored liquid dye to be directed from a reservoir to each of the nozzles where the dye can be atomized into a mist. A momentary actuating button provides a manual switching interface which allows a user to selectively operate the dye distribution system so as to control the dispersal of dye mist from the nozzles. When a user combines this misting activity with the simple act of combing the teeth through their hair, the dye mist is dispersed throughout the portion of their hair being combed.

An electrodischarge apparatus has a nozzle that includes a discharge chamber that has an inlet for receiving a liquid and an outlet. The apparatus has a first electrode extending into the discharge chamber that is electrically connected to one or more high-voltage capacitors. A second electrode is proximate to the first electrode to define a gap between the first and second electrodes. A switch causes the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes from the nozzle ahead of the plasma bubble.

A fluid ejection device is a fluid ejection device adapted to eject a fluent material including an actuator, and a drive signal supply section adapted to output a signal used to drive the actuator, wherein the actuator includes a first piezoelectric element and a second piezoelectric element connected in series to each other. The drive signal supply section is capable of outputting a first drive waveform and a second drive waveform having a voltage change part steeper than that of the first drive waveform to the first piezoelectric element and the second piezoelectric element, outputs the second drive waveform to the second piezoelectric element in a case of outputting the first drive waveform to the first piezoelectric element, and outputs the first drive waveform to the second piezoelectric element in a case of outputting the second drive waveform to the first piezoelectric element.

A fluid ejection device is a fluid ejection device adapted to eject a fluent material, including a fluent material chamber supplied with the fluent material, a moving object, which can reciprocate in the fluent material chamber, a nozzle part having a discharge port communicating with the fluent material chamber, and an inner wall on a periphery of the discharge port on which a tip part of the moving object can contact from the fluent material chamber side, and an actuator having contact with a back end part of the moving object to reciprocate the moving object to thereby discharge the fluent material from the discharge port. The actuator has a plurality of solid-state displacement elements connected in series to each other, and one end of one of the plurality of solid-state displacement elements has contact with the back end part of the moving object.

A surface acoustic wave (SAW) atomizer system for use in providing a nebulized medicament to a patient is described. The system may include a SAW atomization engine with an atomization region on a substrate that is separated from the interdigitated transducers (IDTs) on the substrate by a fluid barrier that seals off liquid fed into the atomization region from the adjacent IDTs and electrical contacts driving the IDTs.

The present invention includes and provides a method of delivering a medicament to an eye of a subject in need thereof a solution, the method comprising: (a) providing droplets containing the medicament with a specified average size and average initial ejecting velocity; and (b) delivering the medicament to the eye, where the droplets deliver a percentage of the ejected mass of the droplets to the eye.
