    Abstract: Un procedimiento para medir la impedancia bioeléctrica en un sistema de medición de biopotencial que incluye al menos dos electrodos (20a, 20b), comprendiendo dicho procedimiento las etapas de: medición de la impedancia bioeléctrica mediante la medición de un voltaje a la frecuencia de una señal de impedancia; cálculo del voltaje de ruido mediante la medición de un voltaje a una frecuencia discreta cercana a la frecuencia de dicha señal de impedancia; y determinación de la validez de la medición de la impedancia bioeléctrica mediante la comparación de dicha impedancia bioeléctrica medida frente a un valor umbral de impedancia de relación señal/ruido.

    Abstract: An array of electrodes is constructed to allow the user to easily adjust to the correct size of the patient's head. The array is self-adhesive, pre-gelled and disposable. The array fits easily over the temple and forehead areas where EEG signals can be acquired by specially designed monitors for purposes of monitoring a number of bodily phenomena, including but not limited to, depth of anesthesia, and/or ischemia, and burst suppression. The array is connected to the monitor via a tab connector that is integral to the disposable device. The tab connector is insertible into a reusable connector that is part of a monitoring system.

    Abstract: Disclosed is a system comprising a microcomputer (18), a user input device (24), a graphics display (20), a hard copy output device (22), a method to derive a diagnostic index indicative of a selected cerebra l phenomena which obtains (19) unipolar EEG signals in an acquisition, and an analysis system (12) from regions of interest on both th e left and right hemispheres of the brain of a subject (15). The system uses high gain low noise amplifiers to maximize the dynamic range for low energy wave components of the signals. Band-pass filtering is used to reduce noise and to avoid an alias. The system applies commonly used digital signal processing (DSP) techniques to digitize, to low pass filter (100Hz), and to decimate the signals. Power spectral, bi-spectral, and higher order spectral processing is then performed.

    Abstract: An electrophysiological electrode includes multiple layers of materials to isolate liquid electrolytic gels from the conductive inks on the flexible circuit of the electrode substrate. Such an electrode has a much longer shelf life under normal storage conditions than other electrodes of such construction with high salt content liquid electrolytic gel, and is able to maintain acceptable impedance upon its eventual use.

    Abstract: The present invention is a system and method that produces features and indices that indicate the presence or absence of a disease or condition, or of the progression of a disease or condition. The system and method of the present invention also produce features and indices that predict responsiveness to medication from a premedication baseline. The system and method of the present invention further incorporates a testing methodology to improve the performance characteristics of the features or indices. To obtain such features and indices, time domain, power spectrum, bispectrum and higher order spectrum values are derived from biopotential signals taken from the subject being tested.
