    • A frangible panel having an electrically-energizable layer carried in an area thereof for heating the panel and main circuit means for supplying electrical power to the layer is provided with circuit breaker means operable to interrupt electrical power to the layer upon breakage of the panel. The circuit breaker means includes a fusible link connected in series with the layer and a solid-state control device connected in the main circuit in parallel with the layer. The solid-state device has a control gate which is connected to a sensing circuit surrounding the electrically-energizable layer and which is connected in the main circuit to render the solid-state control device non-conductive as long as the sensing strip is continuous and to render the solid-state control device conductive when the sensing circuit is broken. Thus, the solid-state control device connects the fusible link to ground and causes the link to blow, thereby interrupting power to the electrically-energized layer.
    • 具有在其区域中承载用于加热面板的可电激励层的易碎面板和用于向层提供电力的主电路装置设置有可在面板断裂时中断电层的电力的断路器装置。 断路器装置包括与该层串联连接的熔断链路和与主电路并联连接的固态控制装置。 固态器件具有控制栅极,其连接到围绕电可激励层的感测电路,并且其连接在主电路中以使固态控制器件不导电,只要感测条带是连续的, 当感测电路断开时使固态控制装置导通。 因此,固态控制装置将可熔接头连接到地,并使连杆发生吹气,从而中断通电层的电力。
