    Abstract: A system is described for use with a magnetometer sensor to provide automatic cancellation of comparatively large steady state ambient magnetic field effects in order to sense the very small magnitude, very low frequency signal information. The system which is effective at the emplacement and initial actuation of the sensor as well as upon the subsequent occurrence of a gross ambient field change, causes a nulling voltage, electrically controlled in predetermined increments, to eliminate the ambient field effects. The resultant magnetometer sensor output responds to input information with full sensitivity and without the direct passband constraints introduced by other ambient nulling techniques.

    Abstract: Threshold and over-the-peak detector circuits are disclosed which in a system configuration provide an interface between input low amplitude analog signals and digital decision logic. The circuits provide threshold information to the decision logic for initiating signal analysis processing at a suitable time prior to the occurrence of the signal peak. Over-the-peak output signals are generated by the system only when predetermined characteristics of the analog signals have been validated.

    CPC classification number: G01R33/02

    Abstract: A circuit technique is described for use with a mangetometer employing a thin magnetic film sensor in an inductance-variation mode, to provide an accurate determination of the absolute value of an external applied field. The technique includes the use of switching means coupled to the thin magnetic film for periodically reversing the state or sense of the film. In the absence of an external field, that is, with zero applied field, the magnetometer output remains at a constant reference level. In the presence of an external field, the magnetometer output is an alternating current signal having an amplitude proportional to the field magnitude and a phase corresponding to the polarity or direction of the field.

    Abstract: A signal peak detection system is disclosed which in a preferred embodiment utilizes the initial actuation of one of a pair of regenerative threshold detectors by an input analog signal, the actuated detector providing threshold information to decision logic for initiating signal analysis processing at a suitable time prior to the occurrence of the signal peak. The system also includes storage units responsive to the respective states of the detectors, and gating circuits for providing an indication of the occurrence of an over-the-peak condition. Depending upon the nature of the input signal, such indication results either from the recovery of the detector initially actuated, or by the concurrent actuation of both detectors as reflected by the presence of output signals from the associated storage units. An over-the-peak output signal is generated by the system only when predetermined characteristics of the input signal have been validated by the decision logic.
