Abstract: A patient interface includes a frame assembly including connectors operatively attachable to headgear, a cushion assembly provided to the frame assembly and including a seal-forming structure structured to form a seal with the patient's nose and/or mouth, and an air delivery connector provided to the frame assembly and operatively connected to an air delivery tube for supplying the air at positive pressure along an air flow path. The cushion assembly is structured to releasably connect to the frame assembly independently of the air delivery connector. The air delivery connector is structured to releasably connect to the frame assembly independently of the cushion assembly.

Abstract: A semiconductor device has a substrate having a plurality of metal traces. A die is electrically attached to a first surface of the substrate. A first plurality of segmented metal traces is formed around a perimeter of the first surface of the substrate, wherein an end section of the first plurality of segmented metal traces is exposed. A mold compound is used for encapsulating the semiconductor device. A first metal plating is formed on a top terminal end section of the first plurality of segmented metal traces. The first metal plating is spread to at least one of the mold compound or the exposed end sections of the first plurality of segmented metal traces. A conductive coating is applied to the mold compound, the exposed end sections of the first plurality of segmented metal traces and to the first metal plating.

Abstract: A seal inspector and a method of inspecting a seal are described. A seal inspector includes an eddy current sensor for detecting changes in an eddy current within a lid seal of a can. The eddy current sensor includes a signal line for creating a magnetic field, which induces the eddy current. The induced eddy current generates a magnetic field that acts on the alternating current and as a consequence produces an eddy current response. A signal processing control unit receives the eddy current response and determines whether a value associated with the eddy current has surpassed a threshold value. If the associated value has surpassed the threshold value, the can may be ejected from a can conveyor system.

Abstract: In a pumping system, a PEEK composite material may be applied to wear areas on internal components. Typically, the internal component provides a metallic substrate which is prepared with a metallic bonding layer arc sprayed onto its surface, at least at the wear area. A powderized PEEK composite material is heated and propelled against the substrate and bonding layer by a high velocity oxy fuel technique. This uniformly coats the substrate providing a durable wear surface for prolonging component life.

Abstract: An electric submergible pumping system having a submergible electric motor with a unique rotor bearing system to promote longevity of the motor. The system includes an electric motor having a housing and a stator mounted within the housing. A shaft is rotatably mounted within the housing for rotation within an interior, axial passage through the stator. A rotor bearing assembly is disposed intermediate the stator and the shaft. The assembly includes a bearing sleeve mounted adjacent the shaft, and a main body portion disposed in sliding engagement with the bearing sleeve. A spring mechanism, such as a wave spring, is engaged with the main body portion. A bracelet is located between the spring mechanism and an interior surface of the stator. The spring mechanism biases the bracelet against the stator to prevent the body portion from rotating during rotation of the shaft.
