  • Methods and implantable medical systems that implement exposure modes of therapy that allow for continued operation during exposure to a magnetic disturbance
    Patent number: 11938326
    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.

  • SLIDE AND PIVOT FENESTRATION UNIT
    Publication number: 20240093546
    Abstract: A fenestration unit is disclosed. In various examples, the fenestration unit includes a plurality of panels, including first and second panels. In some examples, one or more of the plurality of panels is configured to slide relative to a frame of the fenestration unit to provide an opening in the fenestration unit. In various examples, each of the first and second panels are also configured to be pivoted relative to the frame such that the first and second panels can be hinged or otherwise pivoted open to increase the size of the opening in the fenestration unit.

  • CONTRA-ROTATING OPEN FAN PROPULSION SYSTEM
    Publication number: 20150078888
    Abstract: In one aspect a propulsion system comprises an engine and a drive assembly coupled to the engine, comprising a first driveshaft rotatable in a first direction about a first axis, a first fan coupled to the first driveshaft to rotate in the first direction, and a clutch assembly to selectively disengage the first fan from the first driveshaft. Other aspects may be described.
