    • An apparatus comprises an implantable cardiac signal sensing circuit configured to produce a sensed cardiac signal representative of cardiac activity of a subject and a controller communicatively coupled to the cardiac signal sensing circuit. The controller includes a sensing module configured to detect a cardiac depolarization using the sensed cardiac signal and an arrhythmia detection module. The arrhythmia detection module is configured to detect a depolarization rate or interval that satisfies a first tachyarrhythmia detection rate zone threshold, adjust a specified detection duration threshold for the tachyarrhythmia detection zone according to the detected depolarization rate, declare that the detected depolarization rate is an episode of tachyarrhythmia when the detected depolarization rate is sustained for the adjusted detection duration threshold, and provide an indication of the tachyarrhythmia to a user or process.

    • The present invention provides a system and method for fail-safe call survival by detecting failure of an active call serving component and switching the service over to a standby component. The system and method will prevent an existing call, whether established or to be established, from being dropped due to a single point of failure within a Voice over Internet Protocol system. The continuation of the call is based on the failed component as opposed to relying on communication endpoints to re-initiate or re-route the failed call. Call recovery is initiated independent from the call path of a call. The detection of a condition or need for call recovery and the determination to initiate call recovery procedures are made without involving endpoints or intermediate points of the call. The availability and sanity of all components are continuously monitored and are tailored specifically for the duties of each component.
    • 本发明通过检测主动呼叫服务组件的故障并将业务切换到备用组件来提供用于故障安全呼叫生存的系统和方法。 该系统和方法将阻止由于因特网协议系统中的单一故障点而导致的已建立或未建立的呼叫被丢弃。 呼叫的继续是基于故障组件,而不是依靠通信端点重新启动或重新路由失败的呼叫。 呼叫恢复与呼叫的呼叫路径无关。 在不涉及呼叫的端点或中间点的情况下进行呼叫恢复的状况或需要的检测以及发起呼叫恢复过程的确定。 所有组件的可用性和完整性都将不断监控,并针对每个组件的职责量身定做。
