Abstract: A method of processing of electrocardiogram (“ECG”) signals from at least one ECG lead connected to a patient includes computing an average beat from a plurality of beats occurring during a predetermined averaging interval. An R-point, an onset point and a J-point of the average beat is computed to establish a Q-T segment of the average beat. The R-point, onset point and the J-point of the average beat are used to determine a Q-T segment for each beat of the averaging interval, and the average of the Q-T segments of each beat is computed and averaged with the Q-T segment of the average beat.

Abstract: A method of processing of electrocardiogram (“ECG”) signals from at least one ECG lead connected to a patient includes computing an average beat from a plurality of beats occurring during a predetermined averaging interval. An onset point, isoelectric point, and a J-point of the average beat is computed to establish an S-T segment of the average beat. The isoelectric point and the J-point of the average beat are used to determine an S-T segment for each beat of the averaging interval, and the average of the S-T segments of each beat is computed and averaged with the S-T segment of the average beat.

Abstract: This application discloses a planar inductor. The planar inductor includes a first inductor module and a second inductor module that are connected in parallel. A direction of a magnetic line of the first inductor module is opposite to a direction of a magnetic line of the second inductor module, so that the magnetic lines can form a self-close loop in the planar inductor, and impact of a far magnetic field generated by the inductor on the outside, especially a nearby inductor, can be greatly reduced, thereby reducing crosstalk between the inductors, that is, reducing a phase noise, and increasing a Q value of the inductor. In addition, this application further provides a semiconductor chip that includes the planar inductor.

Abstract: A method of processing ECG signals from a plurality of electrocardiogram (“ECG”) leads connected to a patient, applying the ECG signals from the ECG leads to a low-pass filter to obtain a low-band filter (“LBF”) energy values for the lead and to a high-pass filter (“HBF”) to obtain high-band filter energy values for the leads. Running averages of LBF and HBF energy values are utilized to calculate signal-to-noise (“S/N”) ratios for the leads. The S/N ratios are used to select two leads for providing ECG signals to an ECG signal processing algorithm.

Abstract: A medical display system (16) and method display physiological signals. A physiological signal of a patient (14) is received, the physiological signal spanning a period of time. Signal quality of the physiological signal over the period of time is determined. An ECG signal (52) is displayed using a compressed time scale and the determined signal quality (54)n over time is displayed adjacent to the displayed physiological signal.

Abstract: A system for determining the Q and J points of an electrocardiogram (ECG) combines a WLT-based Q, J detection algorithm with signal quality assessment for lead selection. A Q, J detector (24) receives a beat-cycle waveform for the beat under consideration from each of a plurality (N) of ECG leads, and assesses signal quality for each lead using signal quality assessor (SQA) components 261, 262 . . . 26N. The leads with “good” signal qualities are employed for a multichannel waveform length transform (WLT), which yields a combined waveform length signal (CWLS). The Q and J points are then determined from the CWLS.

Abstract: A slurry for chemical mechanical polishing of Co. The slurry comprises components by weight as follows, Inhibitor 0.01-2%, Oxidant 0-5%, Abrasive 0.1-10%, Complexing agent 0.001-10%, and the rest of water. The pH value of the slurries is adjusted to 3-5 by a pH value adjustor. The inhibitor is chosen from one or more kinds of five-membered heterocycle compound containing S and N atoms or containing S or N atom. The oxidant is one or more chosen from H2O2, (NH4)2S2O8, KIO4, and KClO5. The abrasive is one or more chosen from SiO2, CeO2, and Al2O3. The complexing agent is one or more chosen from amino acid and citric acid. The slurry can effectively prevent Co over corrosion and reduce the polishing rate of Co in the polishing process.
