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: There is provided a commitment tracking system that allows for interactive input and output from multiple users including vendors and customers. The commitment tracking system allows the parties to a project to view with transparency the development of the project, its negotiation, finalization, and implementation. The commitment tracking system allows a party to identify individual commitments from multiple commitment sources. Another party can likewise populate a work breakdown structure that includes projects, deliverables, and artifacts. The parties can link individual artifacts with commitments so as to define the agreement and monitor progress and/or changes to the agreement.
