    Abstract: An adaptive non-invasive alternating current brain stimulation system and method includes supplying transcranial alternating current stimulation (tACS) from a tACS source to a person, and receiving electroencephalogram (EEG) signals from EEG sensors disposed on the person, where the EEG signals including stimulation interference. The received EEG signals are processed using an adaptive model to estimate the stimulation interference in the EEG signals. The estimated stimulation interference is subtracted from the EEG signals to estimate neural oscillations of the person. The estimated neural oscillations are processed through an autoregressive model to generate predictions of future neural activity of the person and, based on the generated predictions, one or more electrical characteristics of the tACS being supplied to the person are varied to thereby modulate the neural oscillations of the person.

    Abstract: Methods, systems and apparatuses are provided to perform a continuous-to-continuous mapping of neural signal data received from one or more body sensors connected to an user wherein the one or more body sensors monitors at least neural activities of the user of a sub-vocalized voice at a sensory level and sends the neural signal data to a processor. The processor receives the neural signal data in an iterative closed loop to train the processor and to generate a sufficiently large data set in the neural signal domain to link to a produced voice domain. The processor constructs a common feature space which associates the neural signal domain with the produced voice domain wherein the common feature space implicitly extracts features related to audio communications for linking neural signal domain data to the produced voice data without requiring any prior feature classification of the received neural signal data.

    Abstract: Methods and systems are provided for monitoring sensors and other data sources and detecting data anomalies. One exemplary method involves determining a probable range for a metric influenced by a behavior a sensor based at least in part on historical data associated with the sensor, identifying an anomalous condition with respect to the sensor based on a relationship between a current value for the metric indicative of a current behavior of the sensor and the probable range, and providing a graphical indication of the anomalous condition on a display device.

    Abstract: Methods and systems are provided for calculating and displaying flight safety analytics for an aircraft. The method comprises first receiving historical flight data for the aircraft from a flight data quick access recorder (QAR) located onboard the aircraft. The flight data is then processed to identify safety events and store the identified safety events in an events database. The contents of the events database are analyzed to determine statistical data regarding the identified safety events. An onboard predictive model is applied that utilizes the statistical data to predict the likelihood of a safety event based on current flight data received from the aircraft. The predicted likelihood of a safety event is displayed on a flight display of the aircraft.
