DEFINITION

Classification: 250/227.14

Condition responsive light guide (e.g., light guide is physically affected by parameter sensed which results in light conveyed to the photocell):

(under subclass 227.11) Subject matter in which the light which photocell senses is affected by some property of the light conductor itself which is, in turn, acted upon by the condition or parameter being sensed and the photocell generates an electric signal in response thereto.

(1) Note. The light conductor itself transduces a quantity or parameter which is sought to be measured quantitatively or qualitatively by the photodetector.
