Patent number: 7673820Abstract: A dispenser for dispensing a liquid includes a chamber holding a supply of liquid, an annular conduit substantially filled with liquid from the chamber, and a thermoelectric transducer near one end of the annular conduit. Upon application of electrical current to the thermoelectric transducer, the transducer operates to cause boiling of a quantity of liquid in the annular conduit. Expansion of a resulting bubble forces liquid out the end of the annular conduit. The dispenser may include battery powered electronic control circuit that includes a supercapacitor. The liquid may be dispensed in periodic bursts. In one application, the dispenser is especially suited to automatically and unobtrusively dispense a fragrance, perfume, or other personal care liquid worn by a person. In some applications, the dispenser may be worn on or under an article of clothing, or attached to an article of jewelry.Type: GrantFiled: November 12, 2007Date of Patent: March 9, 2010Inventors: Yehuda Ivri, George Fellingham, Sam Ciuni

Publication number: 20090134235Abstract: In one or more embodiments, a vibration system comprises a vibratable plate, a support member surrounding the vibratable plate, and a vibration-inducing member surrounding the support member, wherein the vibration-inducing member is configured to radially expand and contract against the support member so as to produce axial vibration of the vibratable plate. In one embodiment, the vibratable plate has an outer circumference; a tubular member is concentrically disposed about the outer circumference of the plate, and an annular vibration-inducing member is concentrically disposed about the outer circumference of the tubular member. The vibration-inducing member is preferably a piezoelectric ring that is radially expandable and contractable against the wall of the tubular member to cause the plate to vibrate in the axial direction.Type: ApplicationFiled: April 17, 2006Publication date: May 28, 2009Applicant: Aerogen, Inc.Inventor: Yehuda Ivri

Publication number: 20090108094Abstract: An air freshening device comprises a housing defining a chamber. The chamber contains air and a supply of fragrance material that scents the air inside the chamber. A mechanical oscillator is in fluid communication with the air in the chamber and is configured to transmit acoustic waves in the chamber. A narrow conduit provides a passage from an interior of the chamber to the atmosphere outside the chamber. The conduit is dimensionally configured such that a synthetic jet from the narrow conduit is generated upon activation of the mechanical oscillator, the synthetic jet ejecting scented air from the chamber interior to the atmosphere outside the chamber. The mechanical oscillator may be driven intermittently, resulting in a consistent intensity and character of the emitted scent over the life of the product.Type: ApplicationFiled: October 21, 2008Publication date: April 30, 2009Applicant: Yehuda IvriInventor: Yehuda Ivri

Publication number: 20070209659Abstract: The invention provides methods and apparatus for nebulizing liquids. In one exemplary embodiment, an apparatus is provided which comprises a thin shell member having a front surface, a rear surface, and a plurality of apertures extending therebetween. The apertures are tapered to narrow from the rear surface to the front surface. A liquid supplier is further provided which delivers a predetermined unit volume of liquid to the rear surface. A vibrator vibrates the thin shell member to eject liquid droplets from the front surface of the thin shell member.Type: ApplicationFiled: February 12, 2007Publication date: September 13, 2007Applicant: Aerogen, Inc.Inventors: Yehuda Ivri, Cheng Wu

Patent number: 7201167Abstract: A method of treating a disease involving surfactant deficiency or dysfunction in a patient's lungs is disclosed comprising the steps of providing a liquid lung surfactant composition; aerosolizing the lung surfactant composition with a vibrating aperture-type aerosol generator to form a surfactant aerosol; and introducing the surfactant aerosol into the gas flow within a circuit of a pressure-assisted breathing system coupled to the patient's respiratory system, whereby a therapeutically effective amount of said surfactant is delivered to the patient's lungs. Apparatus is also disclosed that increases the efficiency of delivery of aerosolized medicaments such as aerosolized lung surfactant.Type: GrantFiled: March 14, 2005Date of Patent: April 10, 2007Assignee: Aerogen, Inc.Inventors: James Fink, Yehuda Ivri

Publication number: 20070075161Abstract: A fluid injection device for ejecting fluid droplets in response to electrical signals comprises an oscillating surface that has one or more tapered apertures, each aperture having a first and second opening. The first opening of each aperture is larger than the second opening. The first opening is in surface tension contact with the fluid to be ejected. The fluid interaction with the tapered aperture wall creates cycles of fluid compression and decompression inside the aperture, causing fluid to be drawn from the large opening and ejected out the small opening of the aperture. The device includes a fluid supply nozzle that transports fluid to the oscillating surface at the large opening of the apertures. A discharge valve controls the fluid supply. An electronic wave generator induces oscillation in the tapered aperture containing surface. The device is used to great advantage for fluid atomization and fluid spray.Type: ApplicationFiled: September 18, 2006Publication date: April 5, 2007Applicant: Aerogen, Inc.Inventor: Yehuda Ivri

Patent number: 7083112Abstract: The invention provides exemplary methods and apparatus for dispensing liquids as an atomized spray. In one particularly preferably method, a liquid is dispensed as an atomized spray from a vibratable member having a front surface and a rear surface, with the member having at least one tapered hole between the surfaces for dispensing the liquid. The tapered hole has a larger cross-sectional area at the rear surface than at the front surface. The liquid is delivered from a supply container to the rear surface of the vibratable member in an amount sufficient to cover the hole with liquid. The vibratable member is then vibrated to dispense at least a portion of the liquid through the hole and from the front surface. Additional liquid is delivered from the supply container and to the rear surface in volumes that are substantially equal to the volumes dispensed.Type: GrantFiled: June 6, 2005Date of Patent: August 1, 2006Assignee: Aerogen, Inc.Inventor: Yehuda Ivri
