    摘要: The present invention discloses a rotor of wind energy conversion system (WECS) with the Venturi-tube effect. All the blades mounted on the blade-mounting seat envelop together to form a revolving-body cage turbine, which can be divided from structure into a head portion at the windward end, a tail portion at the wind exhaust end, and an airstream compression portion between the head portion and the tail portion and constituted by the enveloping blades. The revolution diameter of the airstream compression portion is gradually substantially increased from the head portion to the tail portion. The cage turbine forms a dynamic Venturi tube during the revolving process, with which the blade revolves to constitute its outline tube wall with the air permeability. The airstream passes through a window between the blades, and the incoming wind does work towards the blade during the process of permeating from the external space to the internal space of this outline tube wall, thus realizing the energy transfer.

    摘要: An implantable medical device senses a plurality of electrograms from substantially different atrial locations, detects regional depolarizations from the electrograms, and analyzes timing relationships among the regional depolarizations. The timing relationships provide a basis for effective therapy control and/or prognosis of certain cardiac disorders. In one embodiment, an atrial activation sequence is mapped to show the order of occurrences of the regional depolarizations during an atrial depolarization for classifying a detected tachyarrhythmia by its origin. In another embodiment, conduction time between two atrial locations is measured for monitoring the development of an abnormal atrial conditions and/or the effect of a therapy.

    摘要: An implantable medical device controls an anti-tachyarrhythmia therapy by detecting a tachyarrhythmia episode from a cardiac signal and analyzing the detected tachyarrhythmia episode in a tachyarrhythmia detection and analysis process to determine whether the anti-tachyarrhythmia therapy needs to be delivered. The tachyarrhythmia detection and classification process includes detection of inhibitory events each indicating that the tachyarrhythmia episode is of a type not to be treated by the anti-tachyarrhythmia therapy or that the tachyarrhythmia episode is not sustaining. The detection of each of the inhibitory events causes the tachyarrhythmia detection and classification process to be restarted or extended, or the delivery of the anti-tachyarrhythmia therapy to be withheld.
