A rescue system includes a wearable article, such as a wristband, which includes a radio frequency identification (RFID) tag, a radio frequency (RF) beacon, and a power supply. One or more RFID readers (collectively, an RF network) are located on a vessel, the RFID readers being configured to communicate with the RFID tag. Should the RF network detect a passenger overboard event, a modular rocket system is deployed. The modular rocket system comprises a guidance module, the guidance module including a guidance system for guiding the modular rocket system toward a target. A flight control module is removably attached to the guidance module, said flight control module including a plurality of airfoils. A flotation module is removably attached to the flight control module, said flotation module including a flotation device. A rocket motor module removably attached to the flotation module, said rocket motor module including a rocket motor configured to propel the modular rocket system.

A remote control drone assembly to assist in the rescue of distressed swimmers. The drone assembly includes a flotation device that can be released over a distressed swimmer. A retractable spool assembly attached to the drone assembly includes a line having a proximate end tethered to the spool assembly. The drone assembly is constructed and arranged to be flown by an operator over a distressed swimmer. The floatation device is released for use by the distressed swimmer and the drone assembly is returned to the operator. The retractable spool is detached from the drone assembly and attached to a spool retractor. The spool retractor retrieving the floatation device together with the distressed swimmer.

An assembly for implementing an aircraft trajectory includes a flight management system including a viewer, and a display application, on the viewer, for navigation data of the aircraft including waypoints of the aircraft along a trajectory. The flight management system includes an application for recovering tactical track monitoring data, the display application being able to display, dynamically on the viewer, a tactical track positioning symbol corresponding to the or each tactical track being monitored, the position of the positioning symbol being updated by the display application as a function of position data of the aircraft and tactical track monitoring data corresponding to the tactical track, received from a data acquisition apparatus, via a data transmission system.

A valve assembly is provided and includes a valve housing, an actuator housing coupled to the valve housing and configured when actuated to open a normally-closed valve element in the valve housing whereby pressurized fluid is permitted to flow through the valve housing and a solenoid valve. The solenoid valve includes an armature-valve element balanced to remain in a closed position and an electromagnet. The electromagnet generates magnetic flux that moves the armature-valve element into an open position such that at least a portion of the pressurized fluid flows into the actuator housing to actuate the actuator housing.

A drone equipped with a camera, a wireless communication module, an acoustic sensor, a GPS receiver, software and collapsible floatation device patrols above swimmers. The camera and acoustic sensor capture the video and audio of the swimmers. The information is either streamed to a command center or processed by the onboard software. With audio and video analysis capabilities, software is used to detect a swimmer in distress (SID). Alternatively the information is streamed to lifeguard or volunteers all over the world to spot SID. Another detection method is to let swimmer wear a wearable emergency notification device, which sends wireless signals comprising GPS location data. A SID presses a button to indicate rescue request and the drones fly over by GPS signal guidance. Solar power is used as the optional power source of the drones, which would allow the to sustain operation for a prolonged period of time. Once a SID is identified, the drone or drones fly over the SID and drops the collapsible floatation device.

A visual locator target easy to be seen from the air during the day or night to quickly locate and rescue the user in an emergency or distressed situation. The circular single-layer of bright, neon material used for this target may preferably have a diameter of 25 and be a strong, lightweight material the edge will glow-in-the-dark and inflate for water use making it easy to be seen at night for a quicker rescue. It can be used on land by laying it on the ground and securing it by using the eight anchor hook connectors. It can also be used to float in the water with the inflatable, luminescent circumference, center and cross-sections of the target which includes an inflatable chamber therein. The manual back-up air valve system requires the user to blow their breath into the air valve.

Embodiments provide systems and methods for an actuating system for inflating an inflatable structure in which a pressurized fluid piston is coupled directly to the valve an inflatable structure. The coupling of actuator to valve is such that the pairing will remain rigid and secure until the deliberate act of operating the actuator. When the actuator is operated, the actuator displaces a translating chock. This activation simultaneously (a) decouples the valve from actuator, allowing the inflatable to deploy without impedance and (b) activates the inflation of the structure via the valve.
