Publication number: 20150374944Abstract: A mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, may have a substantially under the nose configuration or over the nose configuration. The mask may have a common plenum chamber for both nose and mouth. The cushion may further define a centrally open lip superior region. The cushion may be adapted to couple with the frame directly or to the frame in conjunction with a cushion support clip. Various features of the cushion may further promote sealing and comfort for the under the nose design.Type: ApplicationFiled: February 4, 2014Publication date: December 31, 2015Applicant: RESMED LIMITEDInventors: Craig David Edwards, Lachlan Richard Goldspink, Robert Edward Henry, Andrew Hung, Paul Jan Klasek, Kam Man Law, Grant Milton Ovzinsky, Stuart Norris Plascott, Rupert Christian Scheiner, James Sung, Lance Ian Swift, Matthew Robin Wells

Publication number: 20150315714Abstract: A method of stripping, prepping and coating a surface includes first stripping the exiting coating from a surface, using continuous or pulsed fluid jet, followed by prepping the surface by the same fluid jet. The method also provides entraining particles into a fluid stream, if desired to generate a particle-entrained fluid stream that is directed at the surface to be stripped and prepped. The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to coat the surface. The particles form both mechanical and electronic bonds with the surface.Type: ApplicationFiled: November 10, 2014Publication date: November 5, 2015Inventors: Mohan M. Vijay, Meisheng M. Xu, Emilio Panarella, Wenzhuo Yan, Andrew Hung Tieu, Bruce R. Daniels

Publication number: 20140252107Abstract: A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.Type: ApplicationFiled: May 22, 2014Publication date: September 11, 2014Applicant: VLN Advanced Technologies Inc.Inventors: Mohan M.

Patent number: 8550873Abstract: A method of prepping a surface using a high-frequency forced pulsed waterjet entails generating a high-frequency signal having a frequency f using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip of the transducer to vibrate to thereby generate a forced pulsed waterjet through an exit orifice of a nozzle having an exit orifice diameter d and a length L. The forced pulsed waterjet prepares the surface to within a predetermined range of surface roughness. The surface roughness is determined by selecting operating parameters comprising a standoff distance (SD), a traverse velocity VTR of the nozzle, a water pressure P, a water flow rate Q, a length-to-diameter (L/d) ratio, a microtip-to-orifice distance (a), the frequency f, and an amplitude A of the high-frequency signal.Type: GrantFiled: July 16, 2009Date of Patent: October 8, 2013Assignee: VLN Advanced Technologies Inc.Inventors: Mohan M.

Publication number: 20120204879Abstract: An interfacing structure for a mask system includes a cushion component adapted to contact the patient's face in use and a cushion-to-frame component provided to the cushion component. The cushion-to-frame component is structured to secure the cushion component to a mask frame of the mask system. The cushion-to-frame component includes a cushion side adapted to interface with the cushion component and a frame side adapted to interface with the mask frame. The cushion side includes a platform to engage and support the cushion component. The platform provides an engagement surface to engage the cushion component and inner and outer flanges provided to opposing ends of the platform to guide, support and/or retain the cushion component on the platform.Type: ApplicationFiled: February 14, 2012Publication date: August 16, 2012Applicant: ResMed LimitedInventors: Melanie Lucia CARIOLA, Andrew HUNG, Alicia Kristianne WELLS, Thomas KIRBY, Memduh GUNEY, Craig David EDWARDS, Lee James VELISS

Publication number: 20120080035Abstract: An adjustable mask system (100) includes a cushion with a seal (130) having the ability to change size and/or shape. The seal is preferably a one-piece, continuous member without interruptions. To effect adjustment of the size and/or shape of the seal, an actuator may be provided, which may take the form of a dial (190).Type: ApplicationFiled: June 24, 2010Publication date: April 5, 2012Applicant: ResMed LimitedInventors: Memduh Guney, David Anthony Pidcock, Joel Edward Gibson, Gerard Michael Rummery, Lachlan Richard Goldspink, Craig David Edwards, Andrew Hung, Renee Frances Flower, Rupert Christian Scheiner

Patent number: 7635273Abstract: The present invention provides power supply devices having illuminated receptacles. Some or all of the receptacles are encircled or otherwise circumscribed by a lighting member. The lighting member may be a continuous strip of material, such as an electroluminescent laminate. The lighting member may illuminate the receptacles regardless of whether the receptacles themselves are currently powered. Thus, although the power supply device is in a no or low light environment, or when the device is plugged in but is turned off, a user may easily identify where the receptacles are, which ones are available, and which equipment is plugged into which receptacles. The lighting member may be color coded according to a surge protection rating for the power supply device. In this case, the user can immediately identify which power supply devices have a given surge protection, and can therefore distinguish among different power supply devices having similar physical configurations.Type: GrantFiled: May 22, 2008Date of Patent: December 22, 2009Assignee: Trans USA Products, Inc.Inventors: Elliot Buzil, Andrew Hung, Ken Ku
