Electroencephalogram hashing device for authentication and routing
11681789 · 2023-06-20 · ·

Systems and methods for authenticating and/or routing a digital signal are provided. A system may include a central database configured to store a set of signature brain wave responses as part of a profile of a user. The system may include a transaction device, a sensory device, and an EEG device. When a transaction request is received from the user, the system may be configured to present the user with a sensory prompt, detect a response of the user to the first sensory prompt, compare the response to the signature response in the profile associated with the sensory prompt, and, when the response matches the signature response within a predetermined delta, authenticate and/or route the transaction request.

SYSTEM AND METHOD FOR VALIDATION OF HEARING AIDS FOR INFANTS USING A SPEECH SIGNAL
20230188913 · 2023-06-15 · ·

A system for validation of a hearing aid performance, especially in small children is disclosed. The validation of the performance of hearing aids after having being fitted to a small child who is not able to subjectively provide responses to sounds presented to the child via the hearing aids, is instead done in an objective manner, by using a naturally occurring signal, which has been modulated in order to create an ASSR evoking speech stimulus which is not considered as noise by a hearing aid.

SELF-ADMINISTERED EVALUATION AND TRAINING METHOD TO IMPROVE MENTAL STATE
20170352283 · 2017-12-07 ·

A method and system affects the mental state of a user through cognitive or attention training by providing or displaying a first auditory or visual stimulus to a user, manipulating one or more features of the stimulus to provide or display a second auditory or visual image stimulus, and repeating the steps of manipulating features of the auditory or visual image stimulus to provide or display one or more additional auditory or visual image stimuli to the user. An electronic/computing device receives input from the user, such as EEG signal information, indicating the user's mental state which is evaluated to determine a mood of the user. In response to improvement in the user's mood, the user is rewarded with an additional selected auditory or visual image stimulus. Further, based on improvements in the user's mood, the manipulation of features and provision or display of the stimuli may be adjusted.

DEVICE AND METHOD FOR STIMULATING SLOW BRAIN WAVES

Disclosed is a self-contained device for stimulating slow brain waves, capable of being worn by a person, in particular during a period of time when the person is sleeping. The device includes a supporting element, capable of surrounding the head of a person, and on which electrodes are mounted in contact with the person in order to acquire a measurement signal that represents a physiological electrical signal of the person; an acoustic transducer for emitting an acoustic signal stimulating the inner ear of the person; and on-board conditioning and control electronics for, in flexible real time, receiving the measurement signal and controlling the emission of an acoustic signal synchronized with a predefined slow brain wave time pattern.

SYSTEM AND METHOD FOR ADJUSTING DURATION OF SENSORY STIMULATION DURING SLEEP TO ENHANCE SLOW WAVE ACTIVITY

The present disclosure describes a system configured to adjust the duration of individual sensory stimuli provided to a subject. The system is configured to determine a current amount of slow wave activity in the subject, responsive to the subject being presently in slow wave sleep, control one or more sensory stimulators to provide the individual sensory stimuli to the subject, determine habituation of the subject to the individual sensory stimuli and, responsive to the slow wave activity in the subject for a period of time following the providing of the individual sensory stimuli showing habituation, adjust the duration of the individual sensory stimuli.

System and method for noninvasive identification of cognitive and behavioral goals

A brain machine interface system for use with an electroencephalogram to identify a behavioral intent of a person is disclosed. The system includes an electroencephalogram configured to sense electromagnetic signals generated by a brain of a person. The electromagnetic signals include a time component and a frequency component. A monitor monitors a response of the person to a stimulus and a characteristic of the stimulus. A synchronization module synchronizes the sensed electromagnetic signals with the response and the characteristic to determine a set of electromagnetic signals corresponding to the monitored response and the characteristic. A processor processes the set of electromagnetic signals and extracts feature vectors. The feature vectors define a class of behavioral intent. The processor determines the behavioral intent of the person based on the feature vectors. A brain machine interface and a method for identifying a behavioral intent of a person is also disclosed.

Device and method for examining a phase distribution used to determine a pathological interaction between different areas of the brain

A device for examining a pathological interaction between different brain areas, including a stimulation unit, which administers identical stimuli to a patient in a sequential manner, wherein the stimuli stimulate neurons of the patient in the brain areas to be examined, a measuring unit for recording measurement signals that represent a neural activity of the stimulated neurons, and a control and analysis unit for controlling the stimulation unit and for analyzing the measurement signals. The control and analysis unit transforms the measurement signals into the complex plane, examines the distribution of the phases of stimuli of the measurement signals absorbed by the measuring unit in response to the stimuli delivered to the patient, and determines the probability, with which the phase distribution differs from a uniform distribution, in order to ascertain whether a pathological interaction between the brain areas exists.
