A smart band, for alerting of a user in an emergency, includes a bracelet to be worn by the user. A screen is disposed along the bracelet to display alerts and messages. An alert system notifies that the user is in an emergency. The screen includes technology compatible with an application on a phone or a computer. A GPS tracker identifies and displays a location of the user. The bracelet includes a back surface having a barcode to identify the bracelet. A locking mechanism prevents the user from removing the bracelet. The locking mechanism is unlocked by a tool to allow the bracelet to be removed.

A swimmer safety monitor apparatus for allowing adults to monitor swimming children's safety to prevent drowning includes a transmitter body and a strap coupled to the transmitter body to secure the apparatus on a user's wrist. A transmitter display is coupled to a body front side of the transmitter body. A CPU is coupled within the transmitter body and is in operational communication with the transmitter display. A battery, a biometric sensor, a power button, a panic button, and a transceiver are coupled to the transmitter body and are in operational communication with the CPU to communicate with a personal electronic device to send vitals from the biometric sensor and alerts from the panic button.

An anti-drowning apparatus configured to inflate a balloon when a swimmer with the apparatus is submerged to an unsafe depth so as to help the swimmer return to the surface. The apparatus may be integrated into a swimming garment. An integrated emergency flotation apparatus may also include a manual pump configured to inflate a compression port used to store compressed air for inflating the balloon.

A system for increased safety levels at swimming venues includes an Ultra Wide Band (UWB) tag, a control terminal, and at least three base stations. The UWB tag transmits positioning data of the tag worn by a swimmer and transmits a signal to the at least three base stations. The base stations receive the signal and the positioning data, record time when receiving same, and send the signal, the positioning data, and the time to the control terminal. The control terminal calculates position of the swimmer's UWB tag according to the positioning data and the time when a period of attenuation or disappearance of the wireless connection signal from the immersed UWB tag exceeds a first preset time, generates alarm information, and sends the position of the UWB tag and the alarm information to notify a security officer.

A processor enabled method in a mobile device includes configuring a WiFi radio controller of the mobile device with a WiFi service set identifier of a search detector and configuring a Bluetooth connection configuration of a search detector. The method also includes responsive to a rescue trigger, enabling the device to exit a low power mode while awaiting a connection attempt from a Bluetooth radio via the configured Bluetooth connection configuration. The method also includes upon receiving the connection attempt, powering up the WiFi radio and attempting to connect to the configured WiFi service set identifier.

A monitoring system with one or more wearable devices and an alert station. The wearable device comprises sensors to detect conditions of the wearer and to transmit signals to the alert station. The alert station is configured to declare an emergency upon the occurrence of various events.

A search and rescue drone system includes a buoyant body member, a frame attached to the buoyant body member for carrying a motor and propeller, and an electronic array including a camera, GPS, an EPIRB radio distress beacon, and a transmitter/receiver for remote control flying the drone and communicating with an operator. A laser guidance system may provide coordinates for landing near a swimmer in distress. The search and rescue drone may also be programmed to simply fly to the location of an electronic wearable device, like a bracelet, that is worn by a man overboard. In another embodiment, the search and rescue drone includes pivoting motor mounts, so that it can take off and land vertically with propellers rotating in a horizontal plane, and then the propellers may pivot to rotate in a vertical plane for propulsion across water similar to a fan boat with rescued people aboard.

A signal device for maritime distress rescue and a surveillance device for maritime distress rescue are provided. The signal device for maritime distress rescue which is carried by a user aboard a vessel may include a first communicator configured to communicate with a surveillance device for maritime distress rescue of the vessel, a first position detector configured to generate first position information of the signal device at a predetermined time interval, and a first controller configured to receive second position information of the surveillance device from the surveillance device at a predetermined time interval and determine whether the first position information is within a safe area of the vessel that is set on the basis of the second position information. Accordingly, when a distress occurs, it is possible to transmit a distress signal without operating a switch while minimizing power consumption of the signal device.

A wearable positioning device includes an inertial sensor, a storage device and a processor. The inertial sensor senses an acceleration signal and an angular velocity signal. The storage device stores a previous positioning signal and a current coordinate. The processor is electrically connected to the inertial sensor and the storage device. A wearable positioning method is executed by the processor, which includes: determining whether the wearable positioning device is in one of an under-water mode and an above-water mode according to a pressure sensing signal; calculating, when in the under-water mode, a current acceleration and a current direction according to the acceleration signal, the angular velocity signal, and a swimming posture signal representing a swimming posture; and calculating a current positioning signal according to the current acceleration, the current direction and the previous positioning signal, and updating the current coordinate with the current positioning signal.

A potential drowning incident detection system and its constituent components are disclosed. The system includes a device worn on a head of a swimmer, which includes one or more signal generating units. The signal generating units may be positioned on the device adjacent each temple of the swimmer when worn. The system further includes at least one hub configured to receive wireless signals from the signal generating units, and may further be in communication with a server. The hub and/or server may generate an alert or warning when the signals of the signal generating units are not received by the at least one sensor hub. The alert or warning may further be triggered to a wearable device provided to a responder, such as a life guard. Data collected from the swimmer-worn devices may be stored for later analysis.
