The application relates to a hearing device, e.g. a hearing aid, comprising a first part for being inserted in an ear canal or fully or partially implanted in the head of a user, the first part comprising at least one electrode unit, termed a PR-electrode unit, for making contact to skin or tissue of a user when mounted or implanted in an operational condition, the at least one PR-electrode unit being configured to pick up a physiological response from the user, and wherein the at least one PR-electrode unit comprises an electrically conductive material, e.g. a shape memory alloy. The first part may comprise an implanted part, e.g. in combination with an external part adapted for being located in an ear canal, wherein both parts comprise one or more PR-electrode units. The invention may e.g. be used hearing aids, headsets, ear phones, active ear protection systems, or combinations thereof, e.g. to control processing of the hearing device or to monitor a condition of the user wearing the hearing device.

A patient advisory device (“PAD”) and its methods of use. The PAD may be configured to alert the patient about an estimated brain state of the patient. In preferred embodiments, the PAD is adapted to alert the patient of the patient's brain state, which corresponds to the patient's propensity of transitioning into an ictal brain state, e.g., having a seizure. Based on the specific type of alert, the patient will be made aware whether they are highly unlikely to have a seizure for a given period of time, an elevated propensity of having a seizure, a seizure is occurring or imminent, or the patient's brain state is unknown.

A biological signal measuring equipment used in a measurement of a biological signal in a head portion, has a jaw contact portion that comes into contact with a forehead; an occiput contact portion that comes into contact with an occiput; and a supporter that is interposed in a front and rear direction of the head portion and is supported by the head portion by using the jaw contact portion and the occiput contact portion as ends. The biological signal measuring equipment performs the measurement in the same manner as the case of measuring a wave motion of a short period, even in the case of measuring the wave motion of a long period generated in a head portion.

The present invention discloses a depression assessment system based on physiological information, comprising an information acquisition module, a signal processing module, a parameters calculation module, a feature selection module, a machine learning module and an output result module. The present invention further discloses a depression assessment method based on various physiological information, comprising the following steps: 1, processing electrocardiogram (ECG) signal and one or more of photoplethysmography (PPG) signal, electroencephalogram (EEG) signal, galvanic skin response (GSR)signal, electrogastrography (EGG) signal, electromyogram (EMG) signal, electrooculogram (EOG) signal, polysomnogram (PSG) signal and temperature signal, and calculating signal parameters; 2, normalizing the obtained signal parameters, and performing the feature selection on parameters set formed by the normalized signal parameters to obtain feature parameters set; and 3, performing machine learning by utilizing the obtained feature parameters set, and establishing a depression assessment mathematic model to assess the depression level by utilizing a relationship between the feature parameters set and the depression level. The present invention has the advantage that the subjectivity of the assessment by utilizing the depression rating scale can be avoided.

The circuit may include bio-stimulating signal generating circuit which generates a bio-stimulating signal in a bio-stimulating mode, a bio-signal electrode which delivers the bio-stimulating signal generated in the bio-stimulating mode and receives a bio-signal in a bio-signal measuring mode, a switch block which is turned on when a voltage of the bio-stimulating signal is greater than a first reference voltage which is greater than a second reference voltage or lower than the second reference voltage, first and second resistors, and a bio-signal measuring circuit which measures voltage signals divided by the first and second resistors or measures a signal of the bio-signal electrode according to whether the switch block is turned on. The first and second resistors may be serially connected between the bio-signal electrode and the switch block, and divide a voltage of a signal of the bio-signal electrode when the switch block is turned on.

The present disclosure relates to a method for reducing a listener's task-irrelevant auditory perception, the method comprising providing a measuring device or system configured for measuring the listener's alpha, beta gamma and/or theta activity and providing a generation device or system configured for generating an alpha, beta, gamma and/or theta activity boosting signal that, when provided to the listener will increase the listener's ongoing alpha, beta, gamma and/or theta activity. The listener's alpha, beta, gamma and/or theta activity is measured and if the measured alpha, beta, gamma and/or theta activity is below a predefined threshold, the listener's ongoing alpha, beta, gamma and/or theta activity is increased by the provision of the alpha, beta, gamma and/or theta activity boosting signal to the listener. This results in the listener's ongoing alpha, beta, gamma and/or theta activity being increased, resulting in facilitating reduction of task-irrelevant auditory perception, such as the auditory perception of noise or tinnitus, and thereby also increasing the listener's ability to understand speech under adverse listening conditions. The present disclosure further suggests using the listener's measured alpha, beta, gamma and/or theta activity to judge if the listener is ready to understand speech, and if this is not the case to delay a speech signal until a sufficiently high activity is present.

A method and system for extracting important signal information is disclosed. The method examines a group of signals obtained from testing of a patient's nervous system and finds a signal area of interest. Once a cluster of signals that all have the area of interest is found—the system concludes that the area of interest is located and validated. Signals that are not within the cluster are rejected and the signals within the cluster are signal-averaged to yield a signal-averaged waveform. The signal averaged waveform represents the results of the test.
