Magnetic field-compatible components of a medical diagnostic and/or therapeutic system

A medical device assembly comprises a medical device comprising a shaft having proximal and distal end portions. The device further comprises a sensor at the distal end portion of the shaft that comprises first and second leads extending therefrom to the proximal end portion of the shaft. The device further comprises an electromechanical connector having a plurality of pins at a first end thereof. First and second of the pins are electrically connected to the first and second sensor leads, respectively, thereby forming a first partial magnetic loop between the first and second pins. The connector further comprises first and second jumpers electrically connecting the first pin and third pins, and second and fourth pins, respectively, thereby forming a second partial magnetic loop. The partial magnetic loops are configured to combine with partial magnetic loops of another connector to form a pair of magnetic noise cancellation loops.

Electrical connectors and printed circuits having broadside-coupling regions

An electrical connector that includes a circuit board having a board substrate that has opposite board surfaces and a thickness measured along an orientation axis that extends between the opposite board surfaces. The circuit board has associated pairs of input and output terminals and signal traces that electrically connect the associated pairs of input and output terminals. The input and output terminals being configured to communicatively coupled to mating and cable conductors, respectively. Each associated pair of input and output terminals is electrically connected through a corresponding signal trace that has a conductive path extending along the board substrate between the corresponding input and output terminals. At least two signal traces form a broadside-coupling region in which the conductive paths of the at least two signal traces are stacked along the orientation axis and spaced apart through the thickness and extend parallel to each other for a crosstalk-reducing distance.

Communication Jack Having a Dielectric Film Between Plug Interface Contacts

Embodiments of the present invention relate to designs for network jacks which can be used for cable connectivity. In an embodiment, the present invention is an RJ45 jack that utilizes a thin dielectric film between two layers of PICs that provide crosstalk compensation by way of their geometry. Compensation is achieved by way of capacitor plates which sandwich a thin dielectric film. This allows for the layers of PICs to be in close proximity and achieve higher coupling where desired, allowing a greater amount of compensation to occur close to the plug/jack contact point. This can have the effect of moving compensation closer to the plug/jack contact point, which in turn may reduce the amount of compensation needed further along the data path.
