Abstract: Adaptive performance trainer for guiding a user toward a psychophysiological state. In an embodiment, psychophysiological signal data is received from one or more sensors, and a current psychophysiological state of a user is determined based on the psychophysiological signal data. The current psychophysiological state is compared to one or more goal states, and one or more control signals are generated based on a difference between the current psychophysiological state and the one or more goal states. The control signal(s) cause one or more feedback devices to generate feedback to guide the user toward the one or more goal states. The feedback may comprise an indication to the user of the current psychophysiological state at a pace that replicates the user's heartbeat.

Abstract: Techniques for accelerating training through optimization of the psychophysiological state of the trainee are provided. These techniques include an adaptive performance training system configured to acquire, analyzed, display, and translate data that reflects the psychophysiological state of the user, including the electrical activity of the brain (EEG), the heart (EKG), the musculature (EMG), respiration and other parameters that characterize the state of the user in real-time. The system includes a plurality of feedback mechanisms for providing visual, auditory, and/or tactile feedback based on the current psychophysiological state of the user and for facilitating moving the user toward a goal psychophysiological state for performing a particular task and for optimizing performance of that task.

Abstract: A dry gel-conductive sensor. In embodiments, the sensor comprises a scaffold structure which comprises a structure and a covering. A conductive material, which is both ionically and electronically conductive, may be dispersed within the structure. According to an embodiment, the covering comprises openings which allow conductive material through the covering to contact the skin of a subject. The covering may additionally or alternatively comprise brush-like features configured to penetrate through hair.
