摘要： An authentication system comprises a brain-computer interface (BCI) configured for detecting neural activity in a brain of a subject in response to the subject performing a repeatable mental task, and outputting neural data representative of the detected neural activity. The authentication system further comprises a computer configured for acquiring the neural data output by the BCI while the subject is performing the repeatable mental task, and generating an authorization request containing the neural data. The authentication system further comprises an authentication processor configured for acquiring the authorization request containing the neural data from the computer, authenticating the subject based on the acquired authorization request, and sending an authorization token to the computer.

摘要： Measurements of an arbitrary magnetic field having one or more magnetic field components are acquired from a plurality of magnetometers, and a generic model of at least one of the one or more magnetic field components of the arbitrary magnetic field is generated in the vicinity of the magnetometers. The generic magnetic field model comprises an initial number of different basis functions. Maxwell's equations are applied to the generic magnetic field model to reduce the initial number of different basis functions, thereby yielding a Maxwell-constrained model of the magnetic field component(s) of the arbitrary magnetic field, and the magnetic field component(s) of the arbitrary magnetic field are estimated at each of at least one of the magnetometers based on the constrained magnetic field model and the arbitrary magnetic field measurements acquired from each magnetometer.
