A platform can include a processor and a memory with instructions that cause the processor to: receive biometric information from a plurality of public safety personnel; analyze the biometric information to calculate a stress index; and use the stress index to define and monitor stress in the public safety personnel.

The present invention relates to a method and apparatus to objectively measure stress and fatigue using measurement tools, record stress and fatigue related data in a standardized database, create automated prompts and alerts based upon pre-defined stress and fatigue thresholds (which are derived based upon individual end-user and task performance), provide a number of interventions (which can be preferentially selected by the individual end-user), create data-driven best practice guidelines though meta-analysis of the database, and provide an objective tool for comparative technology assessment.

A body-wearable garment having a hood activated speaker is provided. The body-wearable garment comprises a hood. The body-wearable garment further comprises a speaker integrated within the hood. The speaker is activated in response to receiving a signal from a sensor indicating that the hood is in a deployed state.

A network-based sensing system for monitoring an object is disclosed. The system includes a sensor, attached to the object, that collects object information, a first wireless access point that operates in a first private network covering a first private region, and at least one cellular base station that operates in a public network outside of the first private region. The sensor includes functionality to detect a location of the sensor in a location detection period and to determine a type of network coverage of the sensor. The sensor establishes connection with the first wireless access point via a first private network for transmitting the object information, when the sensor is covered by the first private network, and with the at least one cellular base station via a public cellular network for transmitting the object information, when the sensor is covered by only the public cellular network.

Persons with sleep disordered breathing (SDB) may, or may not, recognize that they have symptoms of SDB, and/or that they may be at-risk of, or suffering certain health problems associated with SDB, including death. The disclosed Energy Conversion Monitor (ECM) sensor, when embodied, for example, in a wearable upper-armband format, has been demonstrated to be more sensitive and responsive than pulse oximetry monitoring of blood oxygen saturation as an indication of hypoxic stress induced by SDB, and is compatible with: (1) inclusion in sleep laboratory polysomnograph (PSG) testing instrumentation, (2) home-based diagnostic testing for SDB, (3) control of home-use airway therapy devices, (4) continuous remote surveillance and refinement of airway therapy, and (5) spot-check and continuous surveillance of sleep quality in the general population. The disclosed ECM also provides new measurements of physiologic stress during and following exercise. When applied during initial care of premature newborn infants, it offers improved therapeutic guidance during their transition from their limited in utero oxygen supply conditions, to the increased oxygen availability from breathing air. When applied during resuscitation of persons suffering from hypoxia and during reperfusion of ischemic tissue, such as during treatment of ischemic stroke, or ischemic heart attack, the ECM sensor can provide objective guidance regarding the safe and effective resupply of oxygen to the hypoxia-adapted tissue to help reduce or prevent microvascular occlusion and cellular injury. As a continuously worn physiologic surveillance monitor, the ECM offers the potential of early detection of sepsis. With the elderly and infirm, it offers a convenient and comfortable means of continuously assessing variations in status while awake and asleep.

The present invention is generally directed to devices, methods, and systems for first responders. It is more specifically directed to devices, methods, and systems that collect data that can be used to improve the performance and safety of first responders. In one aspect, a device for monitoring a first responder is provided, where the device includes: a case, to which is attached an antenna, a status light, and a thermal camera; a flexible printed circuit board assembly connected to an inside portion of the case, wherein the assembly includes GPS, and at least one toxic gas sensor.

A work shoe, in particular a safety shoe, includes at least one passive protection unit which is intended to passively protect a shoe wearer at least against mechanical and/or electrical loads, and includes at least one active protection unit which has at least one sensor unit which is intended to detect at least one characteristic variable at least in order to enable a protection function and/or a comfort function. The sensor unit is configured at least for detecting at least one person-related characteristic variable and/or at least one environmental characteristic variable.

A method, computer program product, and computing system for administering an alertness test on a client electronic device to determine a result for a user, wherein the result is indicative of a level of alertness of the user. Circadian information concerning the user is received. The result for the user is adjusted based, at least in part, upon the circadian information.

A method, computer program product, and computing system for administering a first alertness test to determine a first result for a user, wherein the first result is indicative of a first level of alertness of the user at the time of the first alertness test. At least a second alertness test may be administered to determine at least a second result for the user, wherein the at least a second result is indicative of at least a second level of alertness of the user at the time of the at least a second alertness test. The first result is compared to the at least a second result to identify a level of cognitive decline for the user.

A portable communication device (100) automatically determines user hydration levels while the device is being transmitted. The portable communication device comprises a humidity sensor (120) located by a microphone and touch sensors (124) located on a push-to-talk (PTT) button (110). Data is gathered during PTT switch activation (112). No additional steps are required by the user. Alerts (140) are provided when predetermined dehydration thresholds are approached.
