Abstract: An adaptor for engagement to an air duct. The adaptor includes a back portion with an aperture within the back portion, a bellow adjacent the back portion with an opening positioned in a corresponding relationship with the aperture of the back portion, a top portion adjacent the bellow and spaced-apart from the back portion. A ring member is rotationally engaged to the back portion and disposed within the aperture of the back portion and the opening of the bellow. The ring member receives an ion generation device configured to engaged the ring member and containing a cleaning device for periodically cleaning a pair of electrodes.

Abstract: Fluid pumping systems and methods therefor are disclosed herein. A fluid pumping system includes a diaphragm pump and a strain measurement device. The diaphragm pump is configured to displace fluid provided to an inlet thereof so that the displaced fluid is discharged via an outlet thereof. The strain measurement device is coupled to the diaphragm pump and configured to detect a load applied to one or more components of the diaphragm pump by fluid pressure of the displaced fluid.
