Anode Gate Thyristors and High Current AC Applications:  MicroNote 603 from Microsem  (Circuit / schematic design added 6/06)
Breath Alcohol Tester:  Controls the cars ignition system (Electronic circuit added 5/02)
Catalytic Comustible Gas Sensor:  discussion (Electronic circuit design added 02/05)
Pellistors:  Pellistors employ catalytic combustion to measure combustible gases or vapours in air up to the Lower Explosive Limit (LEL)* of the gas.The standard sensor consists of a matched pair of elements, typically referred to as a detector and compensator (reference element). The detector comprises a platinum wire coil embedded within a bead of catalytic material. The compensator is similar except that the bead does not contain catalytic material and as a consequence is inert.(Electronic circuit design added 02/05)
