A travel case includes a case body defining an interior cavity in which to carry articles and an exterior shell; an inflatable floatation aid fixed to the exterior shell; an inflator in communication with the inflatable floatation aid, for inflation of the inflatable floatation aid; and a locator beacon fixed to the exterior shell, including a communications transmitter capable of signaling a remote party and a geo-locating apparatus.

The present invention proposes a rescue system and method for man overboard with remote monitoring, which is implemented by a rescue system consisted of an onboard processing unit, a distress signal module, an unmanned rescue vehicle, an autonomous ship, a communication module, and a shore control center (SCC). The technical effect of the present invention is that when a person falls into the water, the unmanned rescue vehicle can automatically locate and monitor the falling target immediately, and the shore control center (SCC) can accurately locate the relative position between the unmanned rescue vehicle and the ship where the person falls. Thereby, the shore control center (SCC) can control the rescue process throughout the entire process and release rescue device for rescue.

A control unit for controlling a marine vessel to avoid an emergency situation, the control unit comprising processing circuitry and a storage medium, wherein the control unit is configured to receive path data from one or more sensor devices indicative of a path traveled by the marine vessel in a forward direction and to store the received path data by the storage medium, characterized in that the control unit is configured to receive a trigger signal from an input device, and, in response to the trigger signal, determine a location for turning the vessel around, navigating to the location, turning the vessel around at the location, and navigating the vessel along the path in reverse direction.

It is described an emergency device (100) for divers comprising a watertight case (101) structured to assume a submerged position and an emerged position. The watertight case includes: a depth sensor (102) configured to determine a depth value associated with the submerged position assumed by the emergency device when a user activates an emergency procedure; a positioning device (103) configured to determine a geographic position, including latitude and longitude, assumed by the emergency device (100) in the emerged position; a GSM or satellite telephone transmitter/receiver (104) configured to transmit an emergency message comprising said depth value and said geographic position.

The present invention comprises a self-propelled craft with a U-shaped main body provided with two turbines, one on each flap of the U-shaped main body, which propel the self-propelled craft through turbine operation in a chamber fed by water received by water intakes which is ejected by the ejection openings, and which turbines move inside the turbine operation chamber adopting automatically one of two possible positions due to the casing which is placed in two different positions within the turbine operation chamber, which positioning results from the placement of the device on the water being done by side A or B, the water intake being done through existing water entrances on side A or B of the device.

This new art offers an improvement to conventional surfboards as well as any previous motorized jet surfboards. This application includes an electric powered surfboard equipped with high volume jet drive units that power it forward and significantly improve a surfer's wave fielding and catching ability. Once a wave is caught the drive unit can be shut off by the surfer. Then instantly, two flush fitting glide doors close the jet tube intake openings allowing the surfboard's bottom to return to a planning surface with no protrusions, except for fins, and no water filled jet tubes left open to detract from the surfboard's critical gliding ability when surfing waves. Also, there's a crowned deck shape that allows thin rail sensitivity for turning performance and a motor battery arrangement that provides mass centralization of weight. All this, combined with several wireless control means define this new fine handling motorized surfboard.

A man overboard recovery system for use on a vessel includes one or more unmanned aerial systems configured to autonomously locate and engage a man overboard using onboard sensing equipment. Unmanned aerial system launch, recovery, health and status monitoring, and integration with existing systems is facilitated by a ground station(s) located on the vessel, in the cloud, at a remote monitoring center, or any combination of these. The unmanned aerial system(s) locates a man overboard using onboard sensing equipment including cameras or sensors for heat, infrared, ultraviolet, visible spectrum, radio frequency, or other measurable stimuli that could be used to detect and track the presence of a human body. The unmanned aerial system(s) may be configured to relay data including audio, video, location, health and status information to or from the ground station(s) and to release a payload of safety or survival apparatus in close proximity to the man overboard.

A personal aquatic safety system includes a device that monitors vital signs of the wearer. If one or more of the monitored vital signs falls outside predetermined acceptable parameters, the safety device will emit an alarm and send a wireless distress signal. The safety device may be integrated into a garment such as an inflatable vest and maybe programs to automatically inflate pockets in the vest when the safety device detects that the wearer is experiencing physical distress based on the readings of the vital sign monitor. The monitoring device may also include a deployable tracker that can be released from the safety device and sent to the surface of a body of water so that it may emit a visual and audio alarms, and sends a wireless distress signal.

An emergency position indicating radio beacon that includes a waterproof rigid housing, antenna, a retention carriage strap securely mounted around its exterior periphery on a spool in a storage position. In an emergency the user can unwind the retention carriage strap and form an adjustable loop in the strap using hook and loop fasteners to firmly attach the strap connected to the EPIRB housing to the user's arm that allows a user to transport the radio beacon with the retention carriage strap in a hands-free configuration.

An autonomous navigation type marine buoy includes: a buoy body consisting of a floating body; an internal sensor; a detection unit that receives a GPS signal and information of the internal sensor; an on-water exploration unit that explores a state on a sea; an underwater exploration unit that explores a state under the sea; a determination unit that creates a navigation plan for the buoy body; a propulsion unit that propels the buoy body; a navigation control unit that performs drive control of the propulsion unit so that the buoy body navigates according to the navigation plan; a power generation unit; a power storage unit; a communication unit that communicates with an outside; an emergency signal unit that receives a distress signal and specifies a transmission position of the distress signal; and an evacuation room that accommodates a victim, in which the autonomous navigation type marine buoy has an autonomous navigation mode of performing autonomous navigation to a set position on the sea, a home position mode of autonomously holding a home position at the set position on the sea, and a rescue mode of performing autonomous navigation to the transmission position of the distress signal on the sea when the distress signal is received.
