Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

Abstract: An arrangement and a method for implosion mitigation, and in particular a structural arrangement of a water vessel and a method thereof for mitigating implosion loads. The water vessel includes first and second end portions connected by a middle portion, with one portion structurally weaker than the others so that when the vessel experiences an overmatching load, only the structurally weaker portion of the vessel fails. The vessel may further include energy absorbing structures.

Abstract: Systems and methods configured to alert a portfolio manager (or other asset manager, investor, or proxy) as to the presence of a trade opportunity, such as an order, acceptance of which would improve a portfolio managed by the portfolio manager. The systems and methods may facilitate trading in securities that are illiquid, and additionally may increase anonymity in placing orders.

Abstract: The underwater exterior surface of a watercraft is covered by a deformable protective covering formed from compartmental sections that are dimensionally sized, shaped and mechanically connected to each other for effective attachment of the assembled covering to and removal from the hull of the watercraft. The protective covering is of a cross-sectional construction arranged to provide protection against the damaging effects of underwater explosions by minimizing related adverse physical effects on the entire hull of the watercraft as well as mechanical and electrical components associated therewith.
