Class Information
Number: 250/227.14
Name: Radiant energy > Photocells; circuits and apparatus > Optical or pre-photocell system > Light conductor > Condition responsive light guide (e.g., light guide is physically affected by parameter sensed which results in light conveyed to the photocell)
Description: 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.
