Abstract: Devices, systems, and methods herein relate to processing biosignal data. These systems and methods may obtain sensor data from a plurality of electrodes and may also be used to augment cortical function, treat neurological disease, and provide insight and analysis of biological processes and/or clinical therapeutic outcomes. An implantable biosignal processing system may comprise a lead having at least one biosignal sensor configured to transmit biosignal data based on electrophysiological activity of a subject. A first processing system may be coupled to the biosignal sensor and comprise a plurality of analog signal processing circuits configured to be selectively powered based on a selectable treatment mode. A second processing system in communication with the first processing system and may comprise a plurality of digital signal processing circuits configured to be selectively powered based on the treatment mode. A neurostimulator may stimulate tissue according to the set of biosignal characteristics.

Abstract: A magnetic field measurement system (300), non-transitory computer-readable medium or method can include instructions for, or performance of, actions including receiving output of multiple first magnetic field sensors (302) and multiple second magnetic field sensors (304); and demixing, using the output of the first (N) and second magnetic field sensors (M), at least one signal from at least one target source from signals from other magnetic field sources. The demixing may be performed using a model in which the output of the first magnetic field sensors (N) includes the at least one signal from the at least one target source and that the output of the second magnetic field sensors (M) does not include the at least one signal from the at least one target source.
