Abstract: Systems, computing platforms, and methods for sampling and analyzing common mode noise on electrocardiogram signals to help to minimize the interference to the electrocardiogram signals are disclosed. Exemplary implementations may: obtain electrocardiogram signals from one or more sensors configured to be attached to a patient and communicatively connected to a patient monitor; receive the electrocardiogram signals from one or more sensors by the patient monitor; display the electrocardiogram signals on one or more displays of the patient monitor; sample and analyze a direct current range and an alternating current spectrum to identify common mode interference levels within the obtained electrocardiogram signals; display the direct current range and the alternating current spectrum via the one or more displays of the patient monitor; and update the display of the direct current range and the alternating current spectrum in real time to identify sources of common mode interference.

Abstract: Sensor circuit device for measuring a bio-potential and/or a bio-impedance of a body, including a master circuit, and at least two active bi-electrodes connected to, and remotely powered by, the master circuit via single-wire first connector. The sensor circuit device further includes a single passive current electrode being connected to the master circuit via single-wire second connector. The sensor circuit device cooperates with a biological signal amplifier configured to measure a bio-potential and/or a bio-impedance. Each active bi-electrode is connectable to the biological signal amplifier via the first connector, such that a bio-potential of the body is measurable between the two active bi-electrodes when the active bi-electrodes and the single current electrode are in contact with a surface of the body.

Abstract: A method for pre-processing electrical sensing signals for compensating for common mode to differential mode conversion caused by signal transfer function nonlinearities. Linearization functions are applied to the input signals to counter the nonlinearities. The method includes a calibration process in which a plurality of sets of standardized test signals are applied to the input channels of the measurement operation, and corresponding test outputs measured for each test signal set. The parameters of the linearization functions are set based on the obtained dataset of test outputs.

Abstract: The embodiments of the present disclosure are for a signal processing circuit. The signal processing circuit includes an analog circuit. The analog circuit is used for processing an initial signal it receives. The initial signal includes a target signal and a noise signal. The analog circuit includes a first processing circuit and a second processing circuit. The first processing circuit is used to increase a ratio of the target signal to the noise signal, and output a first processed signal. The second processing circuit is used to amplify the first processed signal. A gain multiple of the second processing circuit to the first processed signal varies with a frequency of the first processed signal. The first processing circuit includes a common mode signal suppression circuit used to suppress a common mode signal in the initial signal, a low-pass filter circuit, and a high-pass filter circuit.

Abstract: Neuromuscular monitoring is described that uses a novel lead assembly and a monitor that can select the appropriate electrodes on the lead assembly and calibrate the stimulation signals applied to the patient through the lead assembly. The monitoring can also set a noise floor value to reduce the likelihood of an erroneous train of four calculations. The present system can automatically sense train of four response of a patient and reduce the likelihood of false train of four indications.

Abstract: The present invention relates to a physiological measurement device (11) comprising a plurality of input channels (23), at least two of the input channels including a digital section configured to process a digital signal (d1, d2) representing an analog signal (e1, e2) present at an electrode (13) assigned to the respective channel, a signal combiner (31) configured to calculate at least one vector signal (x) from at least two processed digital signals (df1, df2). To achieve improved common-mode interference mitigation, it is proposed that the digital section of at least one input channel (23) comprise a digital filter (29) configured to filter the digital signal (d1, d2) based on a set of filter coefficients (G1, G2) and a processor (33) configured for calculating the set of filter coefficients (G1, G2) based on the vector signal (x1).

Abstract: In the present invention, a right leg drive RLD monitoring system is employed on a medical computing system/computer, such as an ECG, HEMO and/or EP monitoring, mapping and/or recording system, that includes a number of RLD circuits to be utilized for different procedures or monitoring states to be performed using the system. The RLD monitoring system operates to actively monitor and/or record the feedback voltage to the RLD isolated from the patient. Using the measured feedback voltage data, the RLD monitoring system can identify and determine if the RLD circuit in use is approaching saturation, has reached saturation and the duration the RLD circuit was in saturation. The RLD monitoring system can concurrently and/or subsequently select and/or provide selection information regarding an optimal RLD circuit to be utilized to most effectively perform the desired function of the RLD in the procedure being performed using the monitoring, mapping and/or recording system.
