Disclosed is a headgear-type device for hazardous air quality warning and air quality improvement, wherein the device can collect biometric information of a worker, wired and wireless communications, and information about the quality of outside air around the worker so as to warn the worker of a hazard or improve air quality at the site. The headgear-type device for hazardous air quality warning and air quality improvement according to the present invention may comprise: a headgear-type biometric sensor which comes into close contact with the head of the worker so as to sense biometric information of the worker and thus allow measurements of the worker's physical conditions; a terminal which is wiredly or wirelessly connected to the headgear-type biometric sensor so as to transmit and receive the biometric information; and a server which receives the biometric information from the terminal, calculates, on the basis thereof, whether the biometric information is in a normal condition range, according to a program, and when the biometric information is not in the normal condition range, issues a warning to the worker by transmitting a warning state to the terminal.

An example of a medical equipment and responder management system is configured to register potential responders to an emergency event, receive event information including an event location and an event type, provide an automatic notification that includes the event information and mapping information to first and second mobile computing devices associated with first responder and second responders selected from the potential responders, receive a confirmation that the first responder will bring a first item of registered medical equipment to the event, and provide an indication to the second mobile device that the second responder should proceed to the event without the first item of equipment, where the mapping information indicates a location of the first item of equipment located near a first mobile device current location and the current locations of the first and second mobile devices relative to the locations of the event and the first item of equipment.

A community based response system for providing lay responders to cardiac arrest emergencies is configured to receive a notification of a cardiac arrest emergency including a location of a cardiac arrest victim, provide an automatic alert to portable devices in a vicinity of the victim, the automatic alert including a selectable control that enables user interoperation with the system, receive an indication from a lay responder, via a respective portable device, that the lay responder will proceed to the location of the victim, and in response to the indication that the lay responder will proceed to the location of the victim, provide at a display screen of the portable device associated with the lay responder a map including the victim's location relative to the lay responder, and a navigational route to guide the lay responder to the victim, and a dispatch text message notification.

A method of operating a personal safety system including a vehicle includes automatically detecting that a smartphone is within a communication range using a wireless communication system of the vehicle, and starting an approach time period with a controller of the vehicle or the smartphone when the smartphone is detected. The method further includes sending checkup data from the vehicle to the smartphone using the wireless communication system when the smartphone fails to arrive at the vehicle prior to the approach time period elapsing, and triggering an emergency response by the vehicle and/or the smartphone when the vehicle fails to receive a response to the checkup data from the smartphone within a response time period.

A method and system are described for automated child monitoring. The system comprises wearable sensor device wirelessly connected to a mobile device. The system comprises sensors configured to detect environmental factors and activities of a child. In one or more embodiments, the activities may be one or more of drinking, vaping, smoking, driving and presence of a threat for a child. The system may be configured to determine real-time location of a wearer as well as contextual information. The sensor device is communicably coupled to one or more mobile devices, additional wearable devices or fixed units. The mobile device is configured to control one or more operations of the inconspicuous wearable device.

Various embodiments relate to a first-aid kit including at least one first aid item; and a wearable device configured to be worn by a user and including: a communications interface for communicating with a mobile device of the user; a sensor for obtaining vitals data when the wearable device is worn by the user; a processor configured to transmit vitals data to a mobile phone of the user via the communications interface wherein the first aid kit includes a means for causing instructions for processing the vitals data to be loaded onto the mobile device. In some such embodiments, the means for causing instructions to be loaded includes: a memory storing contents including at least one of: the instructions for processing the vitals, and a resource identifier that points to the instructions for processing the vitals at an application download server, wherein the contents are transmitted to the mobile device.

In one embodiment, a system includes, but is not limited to, an aviation head-mounted communication device including at least: a speaker, a physiological sensor configured to obtain physiological data, and a wireless communication interface; and a smartphone, a smartwatch, or tablet device wirelessly linked to the wireless communication interface and configured to receive the physiological data and output the physiological data on a display.

Techniques and examples pertaining to a tracking method using a two-component tracking device are described. The tracking device includes two components paired with one another: a first component that is specific to a subject the tracking device is intended to track, and a second component that is generic. The second component is capable of establishing a wireless connection with a cellular network, as well as collecting location information of the second component itself. The tracking method involves receiving from the cellular network a set of requirements associated with the subject, and triggering an action based on the set of requirements and the location information collected. The tracking method enables tracking of multiple subjects without a pairing mistake. Namely, a mismatch between multiple subjects to be tracked and multiple tracking devices intended to track the subjects can be avoided.

A wearable combination drowning prevention and soothing device is operable in either a drowning prevention mode or a soothing mode. In the drowning prevention mode the device monitors a wearer's heart rate and a moisture sensor to determine when, and how long, the device is submerged. Upon occurrence of a condition of those parameters meeting a predefined state consistent with distress, the device transmits an alert signal to an associated mobile device. In the soothing mode the device likewise monitors the wearer's heartrate as well as movements, and upon an indication in those monitored parameter that the wearer may be agitated, the device plays selected audio over a speaker of the device in an attempt to soothe the wearer.

An improved wearable locator has an ultra-low power RF transceiver, GPS receiver, cellular network RF transceiver, processor, programmable non-volatile memory, LCD display, accelerometer and rechargeable battery. To ensure that the locator is within a perimeter, it can cooperate with a subordinate unit that includes an ultra-low power RF transceiver, processor, power supply, DC charging output, rechargeable battery, visual, audible and tactile enunciators and pushbutton, and can be plugged into an outlet or be unplugged and be mobile. Other wireless units can be used to define a perimeter.
