摘要： A method and apparatus for monitoring an electrocardiograph waveform, and for returning an electrocardiograph trace to the middle of a display, such as a chart recorder strip. The monitoring circuit includes an amplifier and a switch for switching the frequency response curve of the monitoring circuit. In a first position, the switch causes the monitoring circuit to have a slow frequency response curve, which allows for accurate monitoring of ECG waveforms. In a second position, the switch causes the monitoring circuit to have a fast frequency response curve, which allows the amplifier of the monitoring circuit to quickly be brought out of saturation. The amplifier of the monitoring circuit becomes saturated when a defibrillation or pace pulse has been applied to a patient who is being monitored. The switch is controlled by a pulse waveform control signal that is provided by a microprocessor. By varying the duty cycle of the control signal, the frequency response curve of the monitoring circuit can be shifted. By changing the duty cycle of the pulse waveform in incremental steps, certain problems can be avoided, such as erroneous QRS detect marks that are otherwise produced. The incremental steps in which the duty cycle of the pulse waveform is changed may be predetermined, or they may be adjusted according to feedback from the amplifier.
摘要翻译：一种用于监测心电图波形并将心电图仪轨迹返回到诸如图表记录器条的显示器中间的方法和装置。监视电路包括用于切换监视电路的频率响应曲线的放大器和开关。在第一位置，开关使得监测电路具有缓慢的频率响应曲线，这允许精确地监测ECG波形。在第二位置，开关使监视电路具有快速的频率响应曲线，这使得监视电路的放大器能够快速地脱离饱和。当除颤或起搏脉冲被施加到被监视的患者时，监视电路的放大器变得饱和。开关由微处理器提供的脉冲波形控制信号控制。通过改变控制信号的占空比，可以改变监视电路的频率响应曲线。通过以递增的步长改变脉冲波形的占空比，可以避免某些问题，例如否则产生的错误的QRS检测标记。脉冲波形的占空比改变的增量步骤可以是预定的，或者可以根据来自放大器的反馈来调整。

摘要： A technique for recognizing and rejecting false activation events related to a capacitance sense interface includes measuring a capacitance value of a capacitance sense element. The measured capacitance value is analyzed to determine a baseline capacitance value for the capacitance sensor. The capacitance sense interface monitors a rate of change of the measured capacitance values and rejects an activation of the capacitance sense element as a non-touch event when the rate of change of the measured capacitance values have a magnitude greater than a threshold level, indicative of a maximum rate of change of a touch event.

摘要： A technique for recognizing and rejecting false activation events related to a capacitance sense interface includes measuring a capacitance value of a capacitance sensor within the capacitance sense interface to generate a measured capacitance value. The measured capacitance value is analyzed to determine a baseline capacitance value for the capacitance sensor. The baseline capacitance value may be updated based at least in part upon a weighted moving average of the measured capacitance value. The measured capacitance value may also be analyzed to determine whether the capacitance sensor was activated during a startup phase and to adjust the baseline capacitance value in response to determining that the capacitance sensor was activated during the startup phase.

摘要： An infusion system for infusing a fluid into a patient comprising an infusion device for delivering the fluid in both a normal delivery pattern and a test pulse and a conduit for conducting the fluid from the infusion device to the patient. The test pulse creates a pressure wave response in the conduit. Abnormal infusion can be detected by determining the area between a baseline and at least a portion of a pressure versus time curve representing the pressure wave response.

摘要： An infusion system includes fluid-delivery components for delivering a fluid from a separate source of the fluid into a patient, transducer components for producing a signal related to the pressure of the fluid in the fluid-delivery components, and identification components responsive to the signal for identifying pressure artifacts characteristic of patient activity. Gravity-fed infusion may be employed as well as infusion with a flow control device, and identification may be accomplished with a microprocessor for examining the waveform of the signal and identifying pressure artifacts characteristic of patient activity amidst pressure changes caused by fluid-delivery components so that site checking can be conducted during quiet periods, i.e., times of little patient acitivity. A method of detecting an abnormal infusion condition includes infusing a fluid into a patient through a conduit, with the pressure of the fluid in the conduit being subject to influence by patient activity, monitoring the fluid pressure in the conduit in order to detect pressure artifacts characteristic of patient activity, and performing a site check for abnormal infusion conditions at a time when no such pressure artifacts are detected.

摘要： A baseline wander filter (BWF) with linear phase response for an ECG signal measuring system includes two cascaded box car FIR filters to estimate the baseline wander. The cascaded box car filters form, in effect, a triangular FIR filter that generates a weighted sliding window average of the input samples to serve as the estimated baseline wander. The estimated baseline wander samples generated by the BWF are then subtracted from the corresponding input ECG samples. The boxcar filters can be designed to avoid multiplication by adding the samples and dividing the resulting sum by the number of coefficients. By choosing the number of coefficients as a power of two, binary division can be performed by shifting the bits of the resulting sum to the right. Accordingly, the present invention avoids the relatively large computational load of conventional FIR filter-based systems. The BWF can be implemented in software in which each boxcar filter uses an accumulator data structure that generates the sum of the previous N samples. When adding the next sample to the sum, it subtracts the Nth previous sample. The output sample of the BWF is equal to the value in the sum buffer, appropriately shifted.
