Abstract: A magnet assembly primarily for use in MRI Interventional applications having an array of four mam permanent magnets that are spaced-apart and arranged into a ring-like geometry with six easy-access openings The magnetization direction in each permanent magnet is anti-parallel to any other adjacent permanent magnet in the ?ng assembly while it is parallel to any other permanent magnet in the array that is oppositely located just as in a quadrupolar system Such an arrangement has the advantage of concentrating the magnetic field inside the nng enclosure while minimizing magnetic field generated outside Together, these four spatially spaced-apart permanent magnets create a very homogeneous and strong magnetic field in the central enclosure with two orthogonal access paths and one parallel access path to the enclosure Through one access pathway a patient can be inserted while through the other pathways a doctor can fully access the patient.

Abstract: An automated torsion driven sports goal practice backstop which appends to any size of sports goal and may remain in place, if desired, at the conclusion of practice and during games. The sports goal practice backstop utilizes a torsioning system and flexible net mechanism in order to provide for easy installation and subsequent tension thereof. During practice, the sports goal backstop of the present invention provides a suitable backstop to stop most balls from traveling beyond the goal. At the conclusion of practice, the sports goal backstop of the present invention is mechanically foldable via automation of rotating handles and thus, the instant system need not be removed at the conclusion of practice. Rather, the sports goal backstop of the present invention may remain in position, out of sight, in its folded configuration during a game without interfering with normal play.
