Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
125 words
IN A SYSTEM FOR DETECTING THE PRESENCE THEREIN OF ICE FORMED DURING RELATIVE MOTION BETWEEN THE SYSTEM AND THE ATMOSPHERE, A FIRST SENSOR ELEMENT, A SECOND SENSOR ELEMENT, SAID FIRST AND SECOND SENSOR ELEMENTS EACH HAVING AT LEAST ONE HOLLOW EXTENSION PROJECTING INTO SAID ATMOSPHERE, EACH SAID HOLLOW EXTENSION CONVERGES TO A PARTICULARLY MINUTE OPENING WHICH PRESENTS A MINUMUM FRONTAL AREA INTO THE DIRECTION OF SAID RELATIVELY MOVING ATMOSPHERE, MEANS TO MAINTAIN SAID FIRST SENSOR ELEMENT AT A TEMPERATURE SUFFICIENT TO PREVENT ICE FROM FORMING THEREIN, MEANS SENSITIVE TO THE PRESSURE DIFFERENCES BETWEEN SAID FIRST AND SAID SECOND SENSOR ELEMENTS DUE TO THE FORMATION AND ACCUMULATION OF ICE IN SAID SECOND SENSOR ELEMENT, AND MEANS RESPONSIVE TO SAID SENSITIVE MEANS TO MELT SAID ACCUMULATED ICE.
Claim 2
Dependent Claim
125 words
