摘要：<p>An ice detector, for detecting the presence of ice and other contaminants formed on a surface, includes a pair of electrodes connected by a pair of leads (42,44) to a control unit (40) which measures the total impedance between the leads (42,44), thereby to sense and to detect the presence of the ice and the other contaminants, using a comparator circuit. The electrodes may be integrated into a patch which can be placed at different locations on an aircraft. <IMAGE></p>
