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 swimmer surveillance system configured to detect swimmers in a water body that are in a state of distress, or in a danger of drowning, and provide an alarm signal for prompting assistance to the swimmers in distress or in a danger of drowning, the system including: a processor; at least one swimmer sensor signally connected to the processor, and configured to attach to a swimmer, acquire data relating to an at least one physiological condition of the swimmer, and transmit the data to the processor; at least one image acquiring device signally connected to the processor, and configured to acquire images of the swimmers in the water body, and transmit visual data of the acquired images to the processor; and at least one alarming device signally connected to the processor, and configured to receive a signal from the processor and in response provide an alarm.

An apparatus for detection of drowning conditions, the apparatus including three depth/pressure sensors attached to a user's torso for identifying angles of the torso in two axes in relation to the water level and two depth/pressure sensors for assessing respiration patterns.

A system may include a user monitor device, a supervisory device, and a subscription sub-system. The subscription sub-system may be configured to: obtain a definition of a boundary that includes a radius from a particular location; monitor a location of the user monitor device; determine that the user monitor device has crossed the boundary; and in response to determining that the user monitor device has crossed the boundary, transmit an alert to the supervisory device.

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 individual monitoring device includes a main body provided with a display screen, a bracelet linked to the main body, a measurement instrument to be positioned opposite a radial artery of the wrist of the user, a processor and a location device. The location device includes a geolocation sensor, an avalanche victim detector and a communications device configured to communicate with a beacon. The device monitors against drowning of a child and includes a first sensor to measure a first parameter physiological parameter of the child, and a second sensor to measure a second physiological parameter of the child. The processor is configured to analyze the first physiological parameter and the second measured physiological parameter, and output information indicating the detection or the non-detection of an anomaly based on the analysis of the first and second physiological parameters.

A system for preventing wandering of an individual includes: a wearable alert device worn by the individual and including a controller, an antenna in communication with the controller, an alert component in communication with the controller for providing an alert to the wearer of the alert device, and a power supply in communication with the controller; and at least one base unit including a controller, the at least one base unit in communication with the alert device. When the alert device is determined to be in an area of caution in relation to the at least one bas unit, an alert is generated on the alert device that is perceptible to the wearer of the bracelet, the alert including one or more of arrhythmic vibrations and audible sounds.

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.

In accordance with embodiments disclosed herein, there are provided systems, methods, and apparatuses for implementing a GPS directional swimming watch for the eyesight impaired. For example, according to one embodiment there is a wearable navigational apparatus including: a mechanical input to receive coordinates for a first location located at an end of a first fixed segment originating from an starting point in a first single cardinal direction; a mechanical input to receive coordinates for a second location located at the end of a second fixed segment originating from the first location in a second single cardinal direction perpendicular to the first cardinal direction, in which the first and second fixed segments form a selected route; a haptic feedback motor having a magnetized compass integrated therein to signal a wearer directional information relative to the first and second locations set, in which the hepatic feedback motor signals the wearer to change direction upon any of: (i) reaching the first location, (ii) reaching the second location, and (iii) deviating from any point along the selected route during bidirectional navigation; and a return function to signal to the wearer, via the haptic feedback motor, directional information relative to the starting point from any point along the selected course. Other related embodiments are described.

A detection system is provided. The detection system comprises a plurality of anchor RF transmitter/receiver modules for being mounted to a structure such that they are placed in a fixed spatial relationship with respect to each other. At least a portable RF transmitter/receiver module is adapted for RF communicating with the anchor RF transmitter/receiver modules. At least a processor adapted for: determining a location of the portable RF transmitter/receiver module based on the RF communication of the same with at least two anchor RF transmitter/receiver modules; determining if the location of the portable RF transmitter/receiver module is inside or outside a predetermined boundary; and, generating an alarm signal if the location of the portable RF transmitter/receiver module is outside the predetermined boundary, the alarm signal being indicative of the location of the portable RF transmitter/receiver module.
