Embodiment Construction

[0020]As used herein, spatial or directional terms such as "inner," "outer," "left," "right," "upper," "lower," "horizontal," "vertical," etc. situation in the attached figure. It should be understood, however, that the invention is capable of various alternative orientations, and thus, such terms should not be viewed as limiting. Furthermore, all numbers expressing dimensions, physical properties, etc., used in the specification and claims, are to be understood as being modified in all instances by the term "about". Accordingly, unless indicated to the contrary, the numerical values ​​set forth in the following specification and claims can vary depending upon the properties desired and / or sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by app...

Abstract

An electrical system responsive to overheating and / or electric arcing of an electrically conductive member, e.g. a heating member of an aircraft windshield, includes a first switch in a first current path, and a second switch in a second current path. The first current path is from an electrical power supply through the first switch, through an arc sensor to the heating member to the power supply. The second current path is from a temperature sensor monitoring the temperature of the heating member through the second switch to a temperature controller. When the temperature of the heating member is at or above a predetermined value, the temperature controller causes the first switch to open. When there is arcing, the second switch is moved to the open position. The temperature controller senses that the second switch is open and causes the first switch to open.
