    摘要: A capacitive sensor for detecting an electrical field generated by a live conductor comprises a source electrode (10), a screen element (20) and an electrical field sensor (30). Said source electrode (10) has a proximal portion (11) connected to the conductor (A) and a distal portion (12) placed inside the screen element (20). The electrical field sensor (30) is placed inside said screen element (20), and faces and is spaced apart from the distal portion (12) of said source electrode (10), in order to detect the electrical field emitted by said source electrode (10).

    摘要: Methods and apparatus for noninvasively estimating a blood pressure are provided. A bandpass filter is applied to a second heart sound (S2) component to generate a filtered S2 component. The bandpass filter has a lower cutoff frequency greater than a maximum frequency of the S2 component. The maximum frequency of the S2 component is estimated using the filtered S2 component, a predetermined relationship is applied between the estimated maximum frequency and blood pressure to generate a blood pressure estimate and the blood pressure estimate is displayed.
