Abstract: In some embodiments, the present disclosure relates an integrated chip including a substrate. A conductive interconnect feature is arranged over the substrate. The conductive interconnect feature has a base feature portion with a base feature width and an upper feature portion with an upper feature width. The upper feature width is narrower than the base feature width such that the conductive interconnect feature has tapered outer feature sidewalls. An interconnect via is arranged over the conductive interconnect feature. The interconnect via has a base via portion with a base via width and an upper via portion with an upper via width. The upper via width is wider than the base via width such that the interconnect via has tapered outer via sidewalls.

Abstract: A hybrid permanent magnet motor rotor rotates around a central axis, and includes: a rotor core provided with a plurality of magnet installation slots; and a plurality of magnet parts embedded inside a plurality of magnet installation slots respectively, wherein the rotor is provided with a plurality of first magnetic pole parts and a plurality of second magnetic pole parts, the magnetic poles of the first magnetic pole part and the second magnetic pole part are arranged in opposite and alternately in the circumferential direction, and the magnetic placement of the first magnetic pole part is different from that of the second magnetic pole part, the amount of magnets used in the second magnetic pole part is greater than that used in the first magnetic pole part.

Abstract: A MRI array coil includes a plurality of first coils in a receive coil array and a plurality of second coils in a transmit coil array. The receive coil array and the transmit coil array are electrically disjoint.

Abstract: A magnetic resonance imaging (MRI) array coil system and method for breast imaging are provided. The MRI array coil system includes a top coil portion with two openings configured to receive therethrough objects to be imaged. The MRI array coil system further includes a bottom coil portion having two openings configured to access from sides of the bottom coil portion the objects to be imaged. The top coil portion and bottom coil portion each have a plurality of coil elements configured to provide parallel imaging.
