Abstract: A patient interface comprises a frame, a headgear, a manifold and two nasal prongs. The frame may be recessed from the face of the patient, and preferably from the manifold so that the manifold may deform or move with respect to the face of the patient. The manifold may be further configured to be compliant in the direction of engagement with the patient's face, such as in the anterior direction. These features may allow the manifold to engage with the face of the patient, such as the upper lip, without exerting a significant pressure which may lead to patient discomfort. The manifold may also be configured to be rotatable with respect to the frame, for example by a grip feature which may be configured to be held in one hand for rotation.

Abstract: A respiratory apparatus for treating a patient with a respiratory disorder includes a blower configured to generate a supply of pressurized breathable gas. The blower includes a gas inlet and a gas outlet. The gas outlet is configured to deliver the generated supply of pressurized breathable gas to an outlet of the respiratory apparatus for delivery to the patient. The blower also includes an impeller configured to rotate to generate the supply of pressurized gas. The impeller has a single shroud with a plurality of blades extending from a surface of the shroud in an upstream direction relative to the direction of flow of the pressurized breathable gas. Each of the plurality of blades radiate outwards from a hub in the shroud. The hub is configured to receive a motor shaft. In addition, the outer diameter of the shroud varies between maximum portions with a maximum outer diameter and minimum portions with a minimum outer diameter.

Abstract: A positioning apparatus for positioning a tactile or optical roughness sensor, a probe or some other measuring instrument with respect to a workpiece can be secured to a movement device of a coordinate measuring machine. The positioning apparatus has a drive that produces a relative movement between two parts of the positioning apparatus, and an inhibiting device, which inhibits the relative movement between the two parts. For this purpose, the inhibiting device has a first friction element and a second friction element each having unlubricated friction surfaces. The friction surfaces are pressed against one another with a normal force that is not variable during the operation of the positioning apparatus. A coefficient of sliding friction that is less than 0.15 acts between the friction surfaces in the case of dryness and without lubrication. Typically, the inhibiting device is arranged in a flexspline of a strain wave gearing.
