Abstract: A biosignal measurement system comprises an adapter for a biosignal measurement device, and an external support structure separate from the adapter. The adapter comprises tool-less connectors, which are repeatedly connectable to and disconnectable from their counter connectors of the external support structure, and a device connector, which has an electrical connection with the tool-less connectors and which has a connection with the biosignal measurement device that the adapter carries. The external support structure comprises an electrode support structure with electrodes and tool-less counter connectors, the electrodes and the tool-less counter connectors having an electrical connection therebetween. The electrodes form an electrical contact with skin for receiving the biosignal. The counter connectors are in electrical contact with the connectors of the adapter for transferring the biosignal to the biosignal measurement device through the adapter.

Abstract: The subject of the invention is a method for calibrating a direct neural interface. The calibration is performed by considering a so-called input calibration tensor, formed on the basis of measured electrophysiological signals and so-called output calibration tensor, formed on the basis of measured output signals. The method comprises the application of a least squares multivariate regression implemented by considering a covariance tensor and a cross-covariance tensor which are established on the basis of input and output calibration tensors corresponding to a current calibration period. The method takes into account covariance and cross-covariance tensors established during an earlier calibration period prior to the current calibration period, these tensors being weighted by a forget factor.

Abstract: A deep intracranial electrode which comprises a flexible wire, an electrode contact, a connector and a shield sleeve, one end of the flexible wire is connected to the electrode contact, the other end connected to the connector; the shield sleeve sheathes around the flexible wire, a sum of a length of a part of the flexible wire arranged outside the shield sleeve and a length of the shield sleeve being adjustable. When the shield sleeve sheaths around the flexible wire, the length of the flexible wire inside the radio-frequency magnetic field of the magnetic resonance equipment may equal to a sum of the length of the shield sleeve and a length of the flexible wire outside the shield sleeve.

Abstract: An electrode includes a core of beryllium copper alloy and a safe metal coating. In some embodiments, the beryllium copper alloy comprises more than three percent beryllium, less than three percent other metals and a remaining percent copper. In some embodiments, an apparatus includes a headband, and a first and second safe metal coated copper-beryllium alloy electrode. The headband is configured to fit snugly to a head of a subject in an orientation from behind a first ear, across a crown of the subject, to a position behind a second ear. The first electrode and second electrode are disposed in the headband to contact a head of the subject at a first position and a different second position, respectively, without gels. In various embodiments, the headband includes a chip to determine an analog signal and transmit data; and, a system includes the headband and a signal analyzing unit.

Abstract: An ear tip for an earpiece including a body, an insertion end, and a retention structure. Some examples include an elongated fin along a portion of an outer leg of the retention structure. Some examples include an extended insertion end configured to insert further into a user's ear canal and including a mushroom cap for providing contact with an interior portion of the user's ear canal and to form an acoustic seal. Some examples may include an umbrella associated with the insertion end, between the mushroom cap and the body. Electrically conductive elements may be associated with any of the elongated fin, the umbrella, and the mushroom cap, to provide electrical contact with the user's skin for sensing electrical signals or for delivery of electrical stimulation.

Abstract: A system for adjusting blood glucose level including an insulin delivery device configured to release insulin into the body of a person, and an EEG monitor having an EEG sensing part including EEG electrodes. The EEG monitor can be arranged in the ear region of the person with the EEG sensing part arranged subcutaneously at the scalp or arranged in the ear canal. The EEG monitor includes an EEG signal processor arranged at the ear and adapted for identifying onset of hypoglycemia. The system further includes a wireless link between the EEG monitor and the insulin delivery device. The EEG monitor is configured to submit a warning signal to the insulin delivery device if an upcoming onset of hypoglycemia is identified. The warning message will cause the insulin delivery device to restrict insulin delivery for a predetermined time, and a warning is provided to the person or to a caregiver.
