    • Described are selectable notch filter circuits comprising at least two different notch filter capabilities, each of which is capable of filtering interference of a designated fundamental frequency and a second harmonic of the designated fundamental frequency from an electrical signal. Each of the notch filters of the circuit is specific for real time filtering of a different designated fundamental frequency and a second harmonic thereof from digitized signal data input into the circuit. The filtering capability of each filter is dictated by control logic, which uses a coefficient set specific for the designated fundamental frequency and harmonics thereof. By using different coefficient sets, different designated fundamental frequencies and at least their second harmonic frequencies can be filtered from digitized signal data input into the circuit. Because the control logic can utilize at a given time any one (or, if desired, none) of the coefficient sets available to it, different interfering fundamental frequencies can be filtered, if and as necessary, from digitized input signal data collected over time at a substantially equivalent sampling rate. Also described are devices including one or more such selectable notch filter circuits, including implantable medical devices such as implantable cardioverter/defibrillators, as well as methods of using such devices.
    • 描述的是可选择的陷波滤波器电路,其包括至少两个不同的陷波滤波器能力,每个陷波滤波器能够从电信号滤除指定的基频的指定基频和二次谐波的干扰。 电路的每个陷波滤波器专用于从输入到电路中的数字化信号数据实时滤波不同的指定基频和二次谐波。 每个滤波器的滤波能力由控制逻辑决定,控制逻辑使用专用于指定基频及其谐波的系数组。 通过使用不同的系数组,可以从输入到电路的数字化信号数据滤除不同的指定基频和至少其二次谐波频率。 由于控制逻辑可以在给定时间利用系统集可用的任何一个(或如果需要的话),可以根据需要随时间收集的数字化输入信号数据滤波不同的干扰基频 基本相当的采样率。 还描述了包括一个或多个这样的可选择的陷波滤波器电路的装置,包括可植入医疗装置,例如可植入的心律转复器/除颤器,以及使用这种装置的方法。

    • An electronic device, like a mobile telephone, has a first section and a second section. The first section and second section are coupled together by a mechanical connection, for example a hinge, swivel or sliding connector. Electronic components in the first section are coupled to electronic components in the second section by conductors capable of transferring power between the first and second sections. A current detector is capable of detecting currents, like surface currents, while a controller is responsive to the current detector. A plurality of reactive elements, like capacitors for example, are coupled to a plurality of switches such that the controller may selectively couple any of the plurality of reactive elements to the conductors by actuating a corresponding switch. When the current detector detects a current in excess of a predetermined threshold, the controller alters the complex impedance between the first and second sections by actuating one or more of the switches, thereby coupling one or more of the reactive elements to the conductors.
    • 诸如移动电话的电子设备具有第一部分和第二部分。 第一部分和第二部分通过机械连接(例如铰链,旋转或滑动连接器)联接在一起。 第一部分中的电子部件通过能够在第一和第二部分之间传递动力的导体与第二部分中的电子部件耦合。 当控制器响应于电流检测器时,电流检测器能够检测电流,如表面电流。 诸如电容器的多个无功元件耦合到多个开关,使得控制器可以通过致动相应的开关来选择性地将多个无功元件中的任何元件耦合到导体。 当电流检测器检测到超过预定阈值的电流时,控制器通过致动一个或多个开关来改变第一和第二部分之间的复阻抗,从而将一个或多个无功元件耦合到导体。

    • A remote control for learning a macro routine of optical signals is provided. An optical receiver is arranged to receive optical signals from one or more original equipment remote controls. The optical receiver outputs electrical signals. A microprocessor receives the electrical signals from the optical receiver. A memory device stores the electrical signals from the optical receiver. An operator interface is electrically coupled to the microprocessor. The operator interface receives operator input to designate a macro routine of operator-selectable optical signals from the original equipment remote control. The microprocessor causes the electrical signals from the optical receiver that correspond to the operator-selectable optical signals from the original equipment remote control to be associated with the designated macro routine and stored in the memory device. Electrical signals associated with a macro designation are retrieved from the memory device and electrically coupled to an optical transmitter.
