A magnetic anomaly detector (MAD) is an instrument used to detect minute variations in the Earth's magnetic field. [1] The term typically refers to magnetometers used by military forces to detect submarines (a mass of ferromagnetic material creates a detectable disturbance in the magnetic field ).
An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, [1] typically as an indicator of fire. [2] They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical [ 3 ] or restricted for use by the height of the building.

A transition-edge sensor (TES) is a type of cryogenic energy sensor or cryogenic particle detector that exploits the strongly temperature-dependent resistance of the superconducting phase transition.
The Mine detector (Polish) Mark I (Polish: wykrywacz min) was a metal detector for landmines developed during World War II. Initial work on the design had started in Poland but after the invasion of Poland by the Germans in 1939, and then the Fall of France in mid-1940, it was not until the winter of 1941–1942 that work was completed by ...
