    • A process for detecting and terminating a fault in a photovoltaic device is provided that operates in the millisecond or faster timescale. A process includes measuring a current or voltage in each of a plurality of strings relative to a common rail. When the voltage or current from a string is outside a predetermined threshold, a flag is generated indicating the presence of a fault in the string. A control unit will detect the flag and disconnect the faulty string from the system through a switch. The use of continuously rolling averages of baseline currents and voltages as well as a series of measurements averaged to measure the difference of current or voltage at each step provides a process and a fault detection system that does not suffer from false fault detections thereby providing a reliable and efficient system for detecting and terminating faults in photovoltaic devices.

    • This disclosure is directed toward techniques for classifying a tachycardia as supraventricular tachycardia or ventricular tachycardia. A method comprises detecting a tachycardia based on at least one value of a cardiac interval, delivering vagal stimulation in response to the detection of the tachycardia, sensing a physiological parameter other than the cardiac interval during or subsequent to delivering the vagal stimulation, and classifying the tachycardia as supraventricular or ventricular based on the sensed physiological parameter. In some examples, the method includes sensing a response of a physiological parameter other than cardiac rate to the vagal stimulation, such as pressure or a morphological characteristic of the cardiac electrical waveform. The method may include providing an indication to a user based on the classification of supraventricular tachycardia, or delivery of appropriate electrical therapy based on the classification of ventricular tachycardia or ventricular fibrillation.
    • 本公开涉及将心动过速分类为室上性心动过速或室性心动过速的技术。 一种方法包括基于心脏间隔的至少一个值检测心动过速,响应于心动过速的检测传递迷走神经刺激,感测在输送迷走神经刺激期间或之后的心脏间隔以外的生理参数,并分类 基于感觉到的生理参数,作为室上性或室性心动过速。 在一些示例中,该方法包括感测除了心率之外的生理参数对迷走神经刺激的响应,例如心电波形的压力或形态特征。 该方法可以包括基于室上性心动过速的分类或基于室性心动过速或心室纤维性颤动的分类递送适当的电疗法来向使用者提供指示。
