  • Cross coupled amplifier
    Patent number: 4476440
    Abstract: An improved differential amplifier includes two Darlington transistor pairs (44-45, 46-47) connected to form a Darlington differential amplifier having complementary sides. Two cross-coupling transistors (50, 52) connect thereto for providing complementary positive feedback of gain less than one between the sides. The cross-coupling transistors significantly improve the differential gain and differential input resistance of the Darlington amplifier.

  • System for detecting heart pacemaker pulses
    Patent number: 4226245
    Abstract: A system is disclosed for accurately providing a signal or signals indicative of the relatively sharp leading edge and the relatively attenuated trailing edge of a pulse and in particular of a pulse applied by a heart pacemaker to a patient's heart. The system of this invention functions to distinctly detect each of the relatively fast rising leading edge and the relatively slow rising trailing edge, while preventing a premature detection of the trailing upon the attenuated or drooping portion of the pacing pulse therebetween.
