A method to optimize learning based upon ocular information of a subject includes providing a video camera for recording a close-up view of a subject's eye. A first electronic display shows a plurality of educational subject matter to the subject. A second electronic display shows an output to an instructor. Changes in ocular signals of the subject are processed through the use optimized algorithms. A cognitive state model determines a low to a high cognitive load experienced by the subject. The cognitive state model is evaluated based on the changes in the ocular signals for determining a probability of the low to the high cognitive load experienced by the subject. The probability of the low to the high cognitive load experienced by the subject is displayed to the instructor.

A computer access control system includes a client electronic device configured to administer an alertness test to a user. A computer access controller is coupled to and configured to be actuated by the client electronic device.

A physical condition change detection device for detecting a change in physical condition of a subject includes a body-surface-side biological information detection unit that is configured to detect a variation in biological information obtained from a body surface of the subject and that is to face the body surface of the subject and an outside thermal variation detection unit that faces away from the body-surface-side biological information detection unit and that is configured to detect a thermal variation in an outside area separated from the body surface of the subject. The physical condition change detection device further includes a transmit unit configured to provide control to transmit detection data of the body-surface-side biological information detection unit and the outside thermal variation detection unit to the outside at every given time.

A fatigue estimation system includes: an information output device (e.g., an imaging device) that outputs information regarding locations of body parts of a subject; and an estimation device that, based on the information output from the information output device in a predetermined time period, estimates a fatigue level of the subject accumulated in the predetermined time period by counting a specific movement that appears in response to fatigue accumulation, and outputs the estimated fatigue level.

A system and method for ergonomic monitoring in an industrial environment that includes tracking task properties of tasks performed by a worker; for a set of tasks, tracking kinematic activity of a worker during each task instance, which includes collecting kinematic data, processing the kinematic data and generating at least one biomechanical measurement of a task associated kinematic activity; and generating an ergonomic model that associates task properties and kinematic activity.

A system or a method for providing pacing guidance to an individual for a particular activity based on a physiological strain index (PSI) or an adaptive physiological strain index (aPSI). The system in at least one embodiment includes a heart rate monitor, a memory storing multiple pacing templates, a clock, an activity completion module, an output device, and a processor configured to perform multiple steps resulting in outputting pacing information to the individual. The pacing information selected in at least one embodiment is based on the individual's heart rate that provides in part a PSI or aPSI, the elapsed time for the activity, and the amount of progress through the activity.

A health monitoring garment is provided. The health monitoring garment includes an article of clothing comprising at least one compression section to provide a snug fit against a person wearing the article of clothing and a sensor island. The sensor island includes stretchable circuitry, two or more sensors, one or more power supplies, and optionally one or more wireless communication modules within a self-contained unit. At least one of the sensors comprises a stretchable sensor which may be a respiration sensor. The sensor unit may be provided independent of the health monitoring garment or as a complete system. The sensor island and compression section of the article of clothing also include fasteners of complementary geometries for reversible attachment and disengagement of the sensor island from the compression section.

A system for monitoring core body movement comprises a sensor device for collecting a data set representing a plurality of core body movements over time from a monitoring device; a processor for determining a plurality of risk scores from the data set; and an output device for indicating the risk scores.

A ballistic body armor damage sensing system having a body armor ballistic plate including at least one ballistic layer and at least one damage sensing layer coupled to the at least one ballistic layer and including a plurality of electrically conductive members which are positioned throughout said damage sensing layer, wherein when a fired projectile impacts the body armor ballistic plate and damages one or more of the electrically conductive members, the damaged electrically conductive members exhibit a measurable change in electrical resistance.

In an approach for monitoring a user's in-flight activity and/or a pattern of movement of a user and warning the user of an in-flight activity or a pattern of movement that could lead to a potential short-term or long-term injury, a processor monitors a body movement and a posture of a user through an application of micro-location analysis enabled by a mesh network of 5G sensors over a period of time. A processor determines whether the body movement and the posture detected can lead to an activity or a series of activities that can result in a potential injury. Responsive to determining a pre-set threshold of risk has been reached, a processor issues a real time alert to the user to warn of the potential injury.
