Patent number: 11883591Abstract: An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user.Type: GrantFiled: October 1, 2020Date of Patent: January 30, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Gregory James Olsen, Peter David Alexander Bearne, Leon Edward Evans, Matthew Roger Stephenson, Craig Robert Prentice, Bernard Tsz Lun Ip, Tony William Spear, Mark Arvind McLaren, Roheet Patel, Brad Michael Howarth, Jonathan David Harwood

Patent number: 8366895Abstract: A differential pH probe design uses a container having an outer surface and an inner volume, where the inner volume is divided into a first chamber and a second chamber. A first pH-sensitive area is located on the outer surface of the first chamber where the first pH-sensitive area is configured to be exposed to a sample. A second pH-sensitive area is located on the outer surface of the second chamber where the second pH-sensitive area is shielded from the sample and is exposed to a buffer solution. A first electrode is configured to detect a first voltage in the first chamber and a second electrode is configured to detect a second voltage in the second chamber. Circuitry is coupled to the first and second electrodes and configured to process the first voltage and the second voltage to determine a pH of the sample.Type: GrantFiled: September 6, 2006Date of Patent: February 5, 2013Assignee: Hach CompanyInventors: John Robert Woodward, Leon Edward Moore, Kevin James West

Patent number: 7721975Abstract: My invention is different in that it uses high temperature water to dissolve either evaporated granular salt, evaporated salt blocks, evaporated salt buttons, solar salt blocks, bulk or bagged solar salt crystals, or halite rock salt crystals to create a highly saturated, highly concentrated salt brine with or without adjuncts such as waste beet juice, molasses, calcium chloride, magnesium chloride to deice streets, roads, bridges, highways, sidewalks, curb cuts, building entrance steps, and airport runways and airplane taxi ways leading to airport runways. The use of the heated salt brine and adjuncts such as waste beet juice or molasses will prevent the solution from being diluted by holding it place with the sucrose or fructose based molasses used to bind the brine to the surface requiring deicing. The use of calcium chloride and magnesium chloride as adjuncts will increase the heated salt brine's effectiveness at lower temperatures.Type: GrantFiled: May 17, 2006Date of Patent: May 25, 2010Inventor: Leon Edward Zaharis
