A system includes a sensing module configured to collect physiological information from a user; an audio input device configured to capture auditory content that is in an environment proximate the user; and one or more processors configured to: determine that a user has entered a state of inwardly focused attention based on first physiological information collected from the user; and in response, record the auditory content captured by the audio input device.

A self-training system is provided, including: a respiration measurement unit, a blood oxygen measurement unit, a blood pressure measurement unit, an electrode unit, an audio stimulation unit, a display unit and a control unit. The display unit displays a virtual image including a plurality of display areas when the display unit is in a normal mode. Said display areas respectively correspond to a pulse transit time data, a brainwave signal, a heart rate variability data, a breathing signal, a heart rate data, a blood pressure data and a blood oxygen saturation signal. The control unit controls the said display areas to display respective real-time display charts according to respective signals and data, and controls the audio stimulation unit to play a binaural beats with frequency following response so that the user can receive stimulations and guidance to lower blood pressure and relieve physiological and psychological stress.

Systems and method of the invention provide an in situ diagnostic system for traumatic brain injury (TBI). In implementations, a method includes: receiving, by a computing device, real-time user parameter data from one or more sensors of the user during a monitoring event; writing, by the computing device, the real-time user parameter data as time series data in a data store; determining, by the computing device, that at least one parameter of the real-time user parameter data meets or exceeds a predetermined parameter threshold value; calculating, by the computing device, a diagnostic score for the user based on the time series data, baseline parameter data of the user, and a determined protective equipment profile of the user; and automatically diagnosing a potential traumatic brain injury (TBI) of the user in situ based on the diagnostic score meeting or exceeding a diagnostic threshold.
