Size-specific electrical connector apparatus optimized for e. g. , biomedical applications, and which prevents mating to the wrong sized terminals. In one embodiment, the connector apparatus comprises a device having a two piece assembly adapted to pivotally engage and lock a sensor such as those used in impedance cardiography (ICG). The conductor is shaped so as to provide a high degree of specificity in sensor connection as well as signal stability and reliability. In one variant, the pivot comprises a spring-loaded pivot having no external stops and the shape of a sensor engaging aperture is defined by a metal insert associated with one element of the assembly and the pivot is permanently formed within the connector. Thus, a user is obstructed from changing the properties of the connector to accept smaller or larger sensors. Methods of manufacturing and operating the connector are also disclosed.

Methods and apparatus for utilizing multiple sources of physiologic data to enhance measurement robustness and accuracy. In one embodiment, phonocardiography or “heart sounds” data is used in combination with one or more other techniques (for example, impedance cardiography or ICG waveforms, and/or electrocardiography or ECG waveforms) to provide more accurate and robust physiological and/or hemodynamic assessment of living subjects. In one variant, the aforementioned methods and apparatus are used to improve ICG fiducial point (e. g. , B, C and X point) detection and identification accuracy. Moreover, the new ICG fiducial points that may be clinically important may be identified using the disclosed methods and apparatus. In a further aspect, the invention discloses methods and apparatus for utilization of ICG and/or ECG waveform information to improve the identification and characterization of heart sounds (such as e. g. , S, S, S, or S heart sounds), murmurs, and other such artifacts or phenomena.
