DEFINITION

Classification: 374/159

Nonelectrical, nonmagnetic, or nonmechanical temperature responsive property:

(under subclass 100) Subject matter wherein the temperature is determined by a change in a property of a sensing element and which property is other than magnetic, electrical, or mechanical.

(1) Note. The term "mechanical" refers specifically to temperature dependent expansion or contraction.

(2) Note. Such a property could include an optical property, luminescence, sorbtion, or a change of state.
