An audiometric test method is provided where a noise stress test is applied to a subject, during the application of the noise stress test measuring one or more indicators reflecting a subjects purinergic hearing adaptation to noise exposure. The measured indicators are analysed to quantify degree of change and rate of change of the subjects purinergic hearing adaptation to noise exposure. An audiometric test system and audiometer configured to perform the test is also provided.

First package information indicating a size or weight of each of packages and first delivery route information indicating first delivery routes are acquired from a memory, where each of the first delivery routes starts from a delivery start point, passes through destinations to which the packages are to be delivered, and ends at the delivery start point. An evaluation value for each of the first delivery routes is calculated based on the first package information and the first delivery route information. An optimum first delivery route is determined, based on the calculated evaluation values, from among the first delivery routes. Information indicating the determined first delivery route is output to an information terminal. The determined first delivery route is displayed on a display of the information terminal. A delivery person delivers the packages to the destinations along the determined first delivery route.

This system is directed to the management of insurance information, risks and coverage, wherein a set of non-transitory computer readable instructions included in a kiosk disposed at the construction site can include instructions for creating a certificate of insurance according to a determination that the insurance requirements have been met and storing the certificate of insurance in the distributed ledger.

The disclosed technology provides a system and a computer implemented method for crisis state detection and intervention of a person or group of persons, the method comprising: providing a computer system designed to detect and intervene non-normal, elevated crisis operating states; using one or more sensors that ascertains a crisis state via physical, behavioral, or cognitive indicators; deducing, with computational hardware, the operational state of a user or users from one or more sensors; and administering an immediate, dual intervention of a sensory form to de-escalate the crisis operating state of a person or group of persons.

The disclosed technology provides a system and a computer implemented method for crisis state detection and intervention of a person or group of persons, the method comprising: providing a computer system designed to detect and intervene non-normal, elevated crisis operating states; using one or more biometric sensors that ascertains a crisis state via physical, behavioral, or mental indicators; deducing, with computational hardware, the operational state of a user or users from one or more biometric sensors; and administering an immediate, dual intervention of a sensory form to de-escalate the crisis operating state of a person or group of persons.

A heartbeat detection device includes a bone conduction microphone that converts, into a signal, displacement on the body surface of a user in a thickness direction of the body of the user, and an extractor that extracts a first frequency component and a second frequency component which are included in the signal. The first frequency component is based on audio information of the user, and the second frequency component is based on heartbeat information of the user. The heartbeat detection device is capable of estimating the physical and psychological state of the user based on the heartbeat information by extracting both the audio information and the heartbeat information, from a signal that has been output by the bone conduction microphone.

A method executed by a computer according to one embodiment includes: extracting a duration time of one or more physical states of a posture or a motion that a person assumes or performs during a performing of a task by analyzing a process of the task of the person; acquiring a load on a body of the person regarding the one or more physical states; and predicting at least one of a fatigue level or a residual physical strength of the person in the task based on the extracted duration time of the one or more physical states and the acquired load.

A contact information obtaining apparatus (100) includes an applied-pressure direction deducing unit (110), a reaction calculation unit (120), and a determination unit (130). The applied-pressure direction deducing unit (110), using pressure data that a pressure sensor that measures pressure that a worker is applying to a target object by a hand of the worker measured, direction data that a direction sensor that measures a direction concerning the hand measured, and characteristic data that indicates a characteristic of the hand, deduces an applied-pressure direction that is a direction of the pressure that the hand is applying to the target object and a direction relative to the target object. The reaction calculation unit (120), using the pressure data and the applied-pressure direction that is deduced, calculates an applied-pressure reaction that is a reaction of the target object to the hand applying force to the target object. The determination unit (130) determines whether or not the applied-pressure reaction is within a reference range.

A system or a method for assisting an individual to acclimatize to hot environment prior to being exposed to the hot environment using a measured heart rate with or without a measured skin temperature and/or a measured body core temperature. A Physiological Strain Index (PSI) or adaptive PSI (aPSI) is calculated for the individual to provide a target for the individual's exertion level such that an area under the calculated PSI/aPSI curve is used to determine the amount of heat acclimatization that has occurred for that particular training session and/or prior training sessions.
