Abstract: An electrical connector assembly includes a female connector, which includes a female connector housing defining a cavity having an hourglass shape and a first array of electrically-conductive pins disposed within the cavity. The electrical connector assembly further includes a male connector that includes a male connector housing having an hourglass-shaped protrusion dimensioned to be inserted into and fit tightly within the cavity and a second array of electrically-conductive sockets, which are contained within the protrusion and are dimensioned and aligned so that upon insertion of the protrusion into the cavity, each of the pins is introduced into and makes electrical contact with a respective one of the sockets.

Abstract: A power line interference (PLI) suppression method includes receiving an input analog signal superimposed with PLI, and digitally estimating one or more harmonics of the PLI in real-time. Responsively to the one or more digitally estimated harmonics, one or more analog harmonic waveforms are outputted, that match the respective one or more harmonics of the PLI. The input analog signal and the one or more analog harmonic waveforms are received, and the superimposed PLI in the input analog signal is suppressed using the one or more analog harmonic waveforms. An analog output signal is outputted, that corresponds to the input analog signal having the suppressed PLI.

Abstract: An ablation system includes multiple electrodes configured to contact body tissue of a patient, including two or more ablation electrodes for contacting respective locations in a target organ and a return electrode. A signal-generating unit includes multiple signal generators, which are configured to apply respective composite signals to respective ones of the ablation electrodes. The composite signals include multiple, respective signal components, including respective ablation signals, having different, respective ablation-signal amplitudes and phases at a common ablation-signal frequency, and respective probe signals having respective probe-signal amplitudes and different respective probe-signal frequencies. A processor is coupled to measure the probe signals received by each of the multiple electrodes, and responsively to the measured probe signals, to control the ablation-signal amplitudes and phases.

Abstract: A wiring assembly includes a differential input port, a differential output port, and first and second pairs of electrical conductors. The differential input port is configured to receive a differential signal from a sensor at a first end of the wiring assembly. The differential output port is configured to output the differential signal at a second end of the wiring assembly. The first and second pairs of electrical conductors are laid out in a three-dimensional (3D) crossover configuration relative to one another and configured to conduct the differential signal from the first end to the second end, and to cancel pickup of a magnetic field by the wiring assembly. The electrical conductors of each pair are connected to one another at the first end and at the second end.

Abstract: An apparatus includes a controllable signal source and a processor. The controllable signal source is configured to apply an Alternating Current (AC) signal to multiple electrodes of a multi-electrode catheter immersed in an aquatic solution. The processor is configured to, responsively to the applied AC signal, estimate a respective surface impedance or a respective electrical noise level of each of the electrodes. The processor is further configured to disconnect each electrode, independently of other electrodes, when the estimated surface impedance or electrical noise level of the electrode drops below a preset value.
