Patent number: 8485182Abstract: A ventilation device for non-invasive positive pressure ventilation (NIPPV) or continuous positive airway pressure (CPAP) treatment of a patient has a gas flow generator, a gas delivery circuit optionally including a humidifier, a controller and sensors monitoring values of operational parameters of the device. The device further includes one or more relationships stored in data storage of the controller relating combinations of parameter values as being indicative of fault conditions of the device operation, the sensors and/or the fault detection process.Type: GrantFiled: December 5, 2011Date of Patent: July 16, 2013Assignee: ResMed LimitedInventors: Gregory A. Colla, Barton J. Kenyon

Patent number: 8129872Abstract: An impeller and at least a portion of a cooperating peripheral volute may be integrated are integrally injection molded with, concentric outer rotor and inner stator assemblies, respectively, to achieve a low profile precision impeller mechanism based on an improved brushless D.C. motor with low length to diameter ratio and suitable for use in a variety of other applications. A rotating cap has an inner circumference which is molded about an outer ferromagnetic back ring that in turn supports a rotor magnet having a number of poles of alternating polarity and separated by a relatively small cylindrical air gap from a fixed stator assembly. The fixed stator assembly is integrally molded into a base housing having a bearing support that extends upwardly through the center of the stator assembly and that is rotatably coupled to a rotating shaft that extends downwardly from the center of the rotating cap.Type: GrantFiled: September 27, 2010Date of Patent: March 6, 2012Assignee: Resmed Motor Technologies Inc.Inventors: Leslie C. Hoffman, Barton J. Kenyon, David B. Sears

Patent number: 7804213Abstract: An impeller and at least a portion of a cooperating peripheral volute may be integrated into, and preferably are integrally injection molded with, concentric outer rotor and inner stator assemblies, respectively, to achieve a low profile precision impeller mechanism based on an improved brushless d.c. motor with low length (L) to diameter (D) ratio and suitable for use in a variety of other applications. In one practical embodiment of such a motor, a rotating cap has an inner circumference which is molded about an outer ferromagnetic back ring that in turn supports a permanently magnetized ring shaped rotor magnet having a number of poles of alternating polarity defined about its inner circumference and separated by a relatively small cylindrical air gap from the outwardly projecting radially oriented selectively magnetized poles of a fixed stator assembly. In one exemplary embodiment, the rotor may have 8 poles and the stator may have 9 poles.Type: GrantFiled: February 27, 2006Date of Patent: September 28, 2010Assignee: Resmed Motor Technologies Inc.Inventors: Leslie C.
