摘要： An ECG recorder and playback unit which includes software-implemented digital signal processing filters which compensate for phase and magnitude distortion occurring when an ECG signal is recorded on a Holter recorder and played back. This permits "tuning" a recorder and playback unit which may be unrelated, as when made by different manufacturers. An impulse or step signal is recorded and played back to provide a system frequency response measurement. Coefficients for a digital correction filter are derived from the discrete Fourier transform of the impulse or step response and a desired system response. When recorded ECG data is played back, it is filtered on a substantially real-time basis with the digital correction filter to compensate for phase and magnitude distortion. Prior to recording, the high frequencies of the ECG signal are boosted to compensate for high frequency losses inherent in the recording and playing back of ECG signals. A calibration pulse and a system characterization pulse are derived by statistically selecting from a plurality of pulses and averaging the selected pulses in order to minimize the effects of noise and tape defects in the pulses. High frequency components of the ECG signal can be amplified prior to recording the signal. This results in decreased amplification, and therefore noise, when the recorded signals are played back. Cardiac pacer pulse detection is performed prior to the step of filtering the played back signal to optimize pulse detection.

摘要： A battery capacity tester method and apparatus are provided. The battery capacity tester determines the present internal battery impedance by measuring terminal voltages during successive applications of a known load, each load drawing a predetermined current from the battery. This calculated internal battery impedance is used to determine battery capacity based on a precharacterization of the battery that establishes a relationship between the internal battery impedance and the remaining battery capacity.

摘要： An ECG recorder and playback unit which includes software-implemented digital signal processing filters which include a method for generating a heart rate variability (HRV) and late potential measurements. The HRV method includes playing back the ECG data on the playback unit and a defining a reference point, usually corresponding to the R-wave peak, on each output ECG signal. An initial period is determined between the reference points. The period is then adjusted so as to align the reference points of the output ECG signals. The amount by which the ECG signals are adjusted is determined by computing a phase difference at a predetermined reference frequency and dividing the phase difference by the reference frequency to produce a period difference. The period is then adjusted by the period difference by adding the period difference to the measured period. The adjusted period is then used to compute the HRV measurement using statistical techniques. In an alternative embodiment of the HRV measurement, an interpolation technique is used to increase the accuracy of the reference point definition and thereby increase the accuracy of the period determination. A phase-ramp technique is employed to improve the frequency resolution of the ECG signal to improve the detection of late potentials.

摘要： A digital displacement encoder that includes a mechanical actuator constructed and arranged to be displaced to one of a null and a plurality of activation positions in response to an externally-provided force. Also included is a conductive member constructed and arranged to be positioned to one of a plurality of intermediate positions in response to the change in position of the mechanical actuator. A contact array comprising a plurality of activation signal contacts is fixedly disposed proximate to the conductive member. Also included is a digital signal generator comprising one or more electrical circuits electrically coupled to the plurality of activation signal contacts, and one more terminals at which output signals are provided. The conductive member electrically contacts a predetermined one or more of the plurality of activation signal contacts when the mechanical actuator is in each of the plurality of positions. At each of the intermediate positions, the conductive member electrically alters the electrical circuits that include the contacted signal contacts to cause a change in output signals. Preferably, the conductive member is comprised of a conductive elastomeric material. Also, it is preferable that a biasing element be included to urge the conductive member toward its null position. The digital signal generator is a voltage pull-up circuit, although any type of circuit may be used. In one embodiment, the digital signal generator provides a plurality of output signals having a nominal state responsive to the mechanical actuator being in the null position, and a plurality of activation states each responsive to the mechanical actuator being in one of the plurality of activation positions. Preferably, the signal contacts are traces on the printed circuit board. The mechanical actuator may be a rocker button, wheel or slide, among others.
