If the bubbles are below the threshold it is displayed to the user as microbubble activity. When a bubble equal to or greater than the threshold is detected an audio and visual alarm is generated and the arterial pump is stopped, this effectively terminates the cardiopulmonary bypass. The operator must identify and remove the bubble before ...
A sample of air is collected from a target volume, which may be the interior truck, pallet, box, or other container, using a vacuum aspiration system. The device that collects this sample is typically known as a "sampler". In portable instruments, the collected air sample is directly injected into the detector.
Gargamelle was a heavy liquid bubble chamber detector in operation at CERN between 1970 and 1979. It was designed to detect neutrinos and antineutrinos, which were produced with a beam from the Proton Synchrotron (PS) between 1970 and 1976, before the detector was moved to the Super Proton Synchrotron (SPS).

An air bubbler level sensor uses a tube with an opening below the surface of the liquid level. A fixed flow of air is passed through the tube. Pressure in the tube is proportional to the depth (and density) of the liquid over the outlet of the tube. [3]
In an ionisation type smoke detector, ambient air is allowed to freely enter the ionization chamber. The chamber contains a small amount of americium-241, which is an emitter of alpha particles which produce a constant ion current. If smoke enters the detector, it disrupts this current because ions strike smoke particles and are neutralized ...
An aspirating smoke detector (ASD) is a system used in active fire protection, consisting of a central detection unit which draws air through a network of pipes to detect smoke. [1] The sampling chamber is based on a nephelometer that detects the presence of smoke particles suspended in air by detecting the light scattered by them in the chamber.

For the moving-filter CPAMs, the above expression is a starting point, but the models are considerably more complicated, due to (1) the loss of material as the filter medium moves away from the detector's field of view and (2) the differing lengths of time that parts of the filter medium have been exposed to the sampled air.
