Personalised calibration methods and devices adapted to identify acoustical corrections to be applied for in-ear dosimetry. The acoustical corrections allow to convert a measured acoustic pressure within the ear-canal of a user to an equivalent acoustic pressure at the ear-drum and/or in free-field. The methods and devices also allow to distinguish noises originating from the user from noises of the environment in the ear occluded by an earplug. Such a distinction is done using two microphones to simultaneously measure the acoustic pressure within the ear-canal and outside the ear-canal. The device may be used to determine a cumulative sound pressure level dosage for which a user being exposed to surrounding sounds over a predetermined period of time.

A method for predicting the intention of a user through an image acquired by capturing the user includes: receiving an image acquired by capturing a user; and predicting the intention of the user for the next motion by using spatial information and temporal information about the user and a target object included in the image.

The present invention is provided to notify a person who makes a movement of a part to be improved in the movement. A movement evaluation system includes: a proficiency degree estimating unit generating a proficiency degree score on the basis of movement data obtained by detecting a movement of a user; an improvement point extracting unit specifying a part of the movement of the user as an improvement point on the basis of the movement data; and an information generating unit generating suggestion information to be presented to the user, on the basis of the improvement point.

An employee health monitoring system includes a quiescent wearable vital sign monitor and a receiving device. The quiescent wearable vital sign monitor has no visual display and transmits vital sign data to the receiving device. Worker health status is monitored by putting the wearable vital sign monitors on workers. The workers' names and work locations are entered into a receiving device having a database. One wearable device is correlated to each of the workers in the database. Vital sign readings are remotely obtained from each of the wearable devices with the receiving device. After determining the health status based on predetermined ranges, workers having normal-range health status are deployed. Workers whose health status is outside of the predetermined normal range are removed from the workplace or rescued.

This disclosure relates to a sensor-based monitor for movements of workers. Multiple inertial sensors are attached to different body parts of the workers. A mobile device application receives the inertial movement data from the sensors and identify movement patterns by applying a trained machine learning model to the inertial movement data. The application then determine for each movement pattern an amount of time that movement pattern occurred and accessing a database to retrieve stored data on an association between the identified movement patterns and injuries. The application calculates a risk value indicative of a risk of injury of the worker as a result of performing the identified movement pattern for the determined amount of time and produces a report detailing the risk value for each of multiple risk categories.

Techniques to detect a non-alert state of a user may include receiving sensor data from an ear-worn electronic device disposed at least partially in the ear of a user, determining an alertness state of the user based on the sensor data, and providing alert data in response to the alertness state comprising a non-alert state to a user stimulation interface of the ear-worn electronic device or to an external device.

Apparatus and methods for utilizing wearable electronic devices at a worksite. A method may include donning an electronic device that contains or is in wireless communication with a processing device that includes a processor and a memory storing computer program code, then performing an action or having an experience, wherein the performed action or experience is detected by the donned electronic device, and then perceiving a sensory signal output by the donned electronic device, wherein the sensory signal output is caused by the processing device based on the detected action or experience.

An industrial machine startup control system for controlling startup of an industrial machine, the industrial machine startup control system including: a vital data measurement device that measures vital data of a worker; a health state analysis device that acquires the vital data of the worker measured by the vital data measurement device, and that determines a health state of the worker based on the acquired vital data; and a startup control device that controls whether or not to allow startup of the industrial machine based on the determination result from the health state analysis device.

A physical stability determination system includes a wearable device configured to collect sleep information, activity information and heartbeat information of a user, a data preprocessor configured to divide each of the activity information and the heartbeat information into data of a sleep area and data of an activity area, based on the sleep information, and a data processor configured to calculate a sleep state, an activity intensity or a heartbeat state of the user from the data of the sleep area and the data of the activity area. The data of the sleep area may be used to calculate the sleep state in the data processor, and the data of the activity area may be used to calculate the activity intensity or the heartbeat state in the data processor.

A neuromuscular enhancement system comprising engineered textile structures is worn by a user to increase strength, preserve energy, and increase motion accuracy. The system can be used in surgery and interface with operating room technology, together providing the surgeon with the ability to perform surgery for longer hours and with increased accuracy. The enhancement system is a flexible structure, worn over the user's body, comprising engineered textile materials that apply forces to different areas of the user's body. The engineered materials can be activated in order to apply a force to a particular region of the body to assist in a desired user output. The engineered materials can be embedded with sensors to detect and monitor motion and other physical properties. The engineered materials can also be embedded with a communication system that conveys information between a computer system and the neuromuscular enhancement system and its various sensors and components. The enhancement system here can be configured for use in applications other than surgery.
