    摘要： A device for gathering data has first and second electrodes. The first electrode is coupled to a surface of interest, and the second electrode is coupled to “everything else” or “the air”. The first electrode is shielded from the second, and from most sources of parasitic capacitance, by a shield that is driven by an active driver that drives the shield to track, and ideally to match, the instantaneous potential of the electrode. The second electrode is likewise shielded in a similar way from most sources of parasitic capacitance. These shields likewise help to limit the extent to which RFI from the device electronics couples with either of the electrodes. In this way the sensing device achieves a markedly better signal-to-noise ratio at frequency bands of interest.

    摘要： Various aspects of the present invention enable robust, reliable control functionality for effectors present on intraluminal, e.g., vascular leads, as well as other types of implantable devices. Aspects of the invention include implantable integrated circuits that have self-referencing and self-clocking signal encoding, and are capable of bidirectional communication. Also provided by the invention are effector assemblies that include the integrated circuits, as well as implantable medical devices, e.g., pulse generators that include the same, as well as systems and kits thereof and methods of using the same, e.g., in pacing applications, including cardiac resynchronization therapy (CRT) applications.
