The disclosed wearable device systems include several features for alerting and guiding persons who are approaching or near to potentially hazardous or high-risk conditions in their nearby environment. Sensor data from wearable devices (also referred to herein as “wearables”) are used to determine the presence of various unsafe environmental conditions and phenomenon, including dangerous terrain or other unusual conditions. The wearable would be used to warn a person, for example via auditory or haptic-based feedback, if the person is about to encounter an unsafe condition. In particular, the proposed systems can be of great benefit to the visually impaired, those persons with physical disabilities, or persons otherwise vulnerable to particular environmental conditions.

A low-cost Internet-of-Things (IoT) earthquake early warning (EEW) device can be deployed at homes, business facilities, and field locations to provide on-site warning and alert regional subscribers. The IoT device is integrated with a sensor, such as a geophone, for ground motion sensing, a single board computer, an analog-to-digital converter, an alert, wireless connectivity, and custom-designed packaging. A custom software application can control the device, detect earthquakes, and issue alerts. The device can run automatically and can be managed remotely. A collection of devices can form a network to provide even more lead time in EEW. For example, if one device detects an earthquake in northern Los Angeles metro area and alerts another device/user/subscriber of the warning service in southern Los Angeles, then the latter gets extra warning time because it could take about 5 to 10 seconds for seismic waves to travel from northern to southern Los Angeles.

Methods for extending cell broadcast notifications to various access technologies and enterprise communication infrastructure. A method includes obtaining, by a controller, a cellular broadcast message of a public warning system and identifying, by the controller, at least one network entity, from among a plurality of network entities operating in a private radio network, based on the at least one network entity being within a location area specified in the cellular broadcast message. The method further includes providing, by the controller to the at least one network entity, the cellular broadcast message.

The present disclosure relates to the field of early warning for geological disasters, and discloses an early warning method for icefall-caused moraine lake outburst disasters, which aims at solving the problems of low early warning precision and difficulty in implementation in an early warning solution of the prior art. The method includes: S1, calculating topographic parameters of moraine lakes and upstream glaciers thereof, and filtering a moraine lake to undertake focal monitoring; S2, calculating a freezing-thawing cycle index and a regional accumulated temperature index of an upstream glacier region for the moraine lake to undertake focal monitoring, S3, calculating a catastrophic climate determination factor T.sub.G-year, wherein if the catastrophic climate determination factor T.sub.G-year satisfies a corresponding catastrophic climate determination condition, an early warning condition is satisfied, otherwise the early warning condition is not satisfied; and S4, implementing early warning.

A distributed weather system includes a storage, a plurality of wireless weather stations, a server, and an interface. Each of the plurality of wireless weather stations is associated with a user and has a battery, a location sensor generating location information, an anemometer generating apparent wind speed, a transmitter transmitting the location information with the apparent wind speed to a network at periodic intervals, and a receiver receiving control commands that include a length of the periodic intervals. The server receives the location information with the apparent wind speed and stores them in the storage. The interface is accessible by a mobile computer, and receives the control commands from a user and sends them to the receiver of the wireless weather station associated with the user. The interface displays a true wind speed for each of the plurality of wireless weather stations, which is calculated using the apparent wind speed, the location information, and historical location information.

A method for a disaster notification service not requiring collecting of location information, and systems thereof. The method includes the steps of: receiving, from at least one registration system, disaster information including a disaster location and disaster notification information; specifying, a set of location information, each including location information which corresponds to the disaster location of each of at least one item of disaster information; transmitting, the specified set of location information to a plurality of user terminals; if any one of the plurality of user terminals determines that the location of the user terminal is included in matching location information included in the set of location information, receiving, a content transmission request including identification information of the matching location information; and transmitting, content including the matching disaster notification information corresponding to the matching location information in response to reception of the content transmission request.
