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: A process is disclosed for anodically bonding an array of spacer columns to one of the inner major faces on one of the generally planar plates of an evacuated, flat-panel video display. The process also includes an evacuated flat-panel display having spacer structures which are anodically bonded to an internal major face of the display, as well as a face plate assembly manufactured by the aforestated process.
