An in-line gas ionizer has a gas inlet, an ionizing chamber, and a gas outlet, wherein at least one of the gas outlet and the ionizing chamber comprises static dissipative material which may be connected to ground.

In-line gas ionizer with static dissipative material and counterelectrode

An apparatus for detecting a static field includes two surfaces of conductive material that are: (i) electrically coupled to each other, and (ii) adjacent to each other. The two surfaces repel each other in the presence of a static field. A rupturable indicator bridging and coupled between the two surfaces ruptures upon repulsion of the two surfaces from each other by at least a predetermined distance.

Foil-leaf electrometer for static field detection with triggered indicator

An apparatus for detecting a static field includes a microelectromechanical systems (MEMS) device having two cantilevered beams of conductive material that are adjacent and substantially parallel to each other. The two beams repel each other in the presence of a static field. At least one sensor detects a respective amount of displacement of the two cantilevered beams from a rest position and determines an amount of repulsion of the two cantilevered beams from each other.

MEMS electrometer that measures amount of repulsion of adjacent beams from each other for static field detection

An apparatus for detecting a static field includes two surfaces of conductive material that are (i) electrically coupled to each other, and adjacent to each other. The two surfaces repel each other in the presence of a static field. The conductive material has a deformation property such that stress caused by repulsion of the two surfaces from each other by at least a predetermined distance causes at least one of the surfaces to permanently deform.
