Abstract
A signal generating means comprising a bistable magnetic device which alters its magnetic state when the density of magnetic flux to which it is subject passes through a predetermined value, and detecting means providing an output signal responsive to a change in magnetic state of said bistable device. A conducting means comprising first and second portions conducts magnetic flux in first and second paths and subjects the bistable magnetic device which is connected between the first and second portions to the conducted magnetic flux. The second portion provides the second path with an alterable permeance for varying the reluctance of the second path of the conducting means, and an energizing means provides magnetic flux to the conducting means having a sense along the first path through the bistable device which is opposite to its sense in the second path. The density and sense of magnetic flux to which the bistable device is subject to changes with the variation of reluctance of the second path of the conducting means to alter its state.
