DEFINITION

Classification: 117/29

Passing non-induced electric current through a crystal-liquid interface (e.g., Peltier):

(under subclass 13) Subject matter in which the crystal and the liquid are connected to an electric potential and current is caused to flow therebetween.

(1) Note. RF induction, per se, is not proper for placement here.
