A method and system for integrity testing of sachets. The method comprises the steps of disposing at least a portion of the sachet relative to an electrode structure; applying an AC bias voltage to the electrode structure; measuring an electrical property of the portion of the sachet over a frequency range, and determining the integrity based on the measured electrical property over the frequency range.

An apparatus for the continuous monitoring of a pipeline or a pipeline network carrying flowing media that can not only detect the presence of a leak but also locate the source of the leak through the use of rarefaction wave detection and a method of using the same is disclosed within. The apparatus and method are specifically configured to locate the leak source within less than 36 inches using a calibration means and a noise cancellation means.

Embodiments disclosed herein relate to a base plate and/or a sensor assembly part of an ostomy appliance. In embodiments, the base plate and/or the sensor assembly part comprises a first adhesive layer, a masking element, and a plurality of electrodes. The first adhesive layer includes a stomal opening with a center point and a proximal surface configured to be attached to a skin surface of a user. The masking element is arranged on a distal surface of the first adhesive layer, and is more insulative than the first adhesive layer. Further, the plurality of electrodes are arranged on a distal side of the first adhesive layer. Each electrode includes a sensing part and a conductor part and the masking element is arranged between the conductor parts and the first adhesive layer.

The present invention relates to a phase separation sensor which can easily change its direction due to its flexible feature without using a corner connector even at a position limited in space or at a narrow space, and can separate and sense water and chemical solution so as to be easily used in outdoor environment exposed to rain, snow, hail or others. The phase separation sensor includes: a detection part (100) having a pair of detection lines (110, 120) spaced apart from each other in a width direction to be arranged side by side; and an insulation part (200) having insulation films (210, 220), which have detection holes (210a, 220a) formed at equal intervals in a longitudinal direction to be opposed to the detection part (100) and adhesive layers (211, 221) formed at areas of the insulation films (210, 220), which touch the detection lines (110, 120).

Systems and methods for locating an obstruction or leak in a conveyance. The systems include an emitter operable to emit a signal or signals through the conveyance. The systems further include a receiver operable to receive a reflected signal or signals from the obstruction or leak. The systems further include a processor programmed to analyze the received reflected signal and determine the location of the obstruction or leak in the conveyance. The methods include emitting a signal or signals from an emitter through the conveyance, receiving a reflected signal or signals reflected from the obstruction or leak with a receiver, and analyzing the received reflected signal or signals using a processor to determine the location of the obstruction or leak in the conveyance.

Methods and apparatus for detecting moisture that includes at least three conductors. One of the conductors has a different resistance than the other conductors. A liquid extends between the conductors. The difference between the impedance through a pair of conductors and the liquid and the impedance of through another pair of conductors and the liquid may be used to determine the position of the liquid along a length of the conductors. Similar methods may be used to determine an area of a liquid with respect to the conductors.
