The present invention relates to motor safety devices as used in increasing numbers for the killing of engines or disengaging propulsion units from motors, when there are no operators to maintain control of an apparatus or vehicle such as jet-ski, boat, go-kart and the like or personnel to oversee use of a motorised tool or the like. Motor boat operators on a boat have been known to fall overboard without being detected by the operator of the boat. Such runaway boats have been known to seriously injure the operator of the boat in the water since a runaway boat tends to circle back to the place where the operator has fallen overboard. The present invention is also applicable to other types of equipment such as motorised gymnasium equipment, hand operated power tools, such as agricultural and arboriculturist equipment and wood working tools.

A system for repelling sharks is disclosed. Magnets are connected to a rod along its length. If necessary, the rod may be extended. Additionally, one or more flotation devices may be connected to the rod to manipulate or adjust the buoyancy of the system, depending on the user's objective(s). The rod is connected to a fishing line once a fish is hooked and is in close proximity to the boat or other structure from which the fisherman is fishing. The weight of the rod and magnets cause the rod to slide down to the end of the fishing line, where the rod will come in contact with the hooked mouth of the fish. As the fish struggles during the fight, the rod creates a protective magnetic field around the fish to deter sharks from engaging the fish.

An inflatable device is provided, and contains a body and a mouth. The mouth is positionable in an open position and a sealed position. The body includes a flexible body wall that defines an interior volume. The body defines at least one air flow path from the mouth through the interior volume. The air flow path has an air flow path axis and has a cross-sectional area. The body further includes at least one structural member that applies a force on the flexible body wall transversely outward from the axis so as to urge the flexible body wall towards a transversely expanded state. The body is movable between an axially collapsed state and an axially open state along at least a portion of the air flow path and is urged towards the axially expanded state by a force applied by at least one of: the at least one structural member, and air flow into the body through the mouth when the mouth is held in the open position.

A prefabricated house including: a steel-frame foundation where H-shaped steels are connected in a rectangular contour, a vertical frame and a horizontal frame composed of an H-shaped steel are arranged inside the connected H-shaped steels, and inclined frames are mounted at four corners of the rectangular contour; a seismic isolation rubber supporting the steel-frame foundation on a foundation of the prefabricated house via a supporting frame; a rectangular floor member; outer wall members erected from four peripheries of the floor member; an inner wall member mounted at a position partitioning the floor member; and a roof member with a mountain-shaped section mounted on the outer wall members via a climbing beam, wherein changing positions of a window and a door and changing a room layout can is possible by changing positions of the wall member panels or reversing outer and inner faces or upper and lower sides of these panels.

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 system for controlling a watercraft includes a wireless communication device corresponding to a passenger of the watercraft. A controller is in communication with the wireless communication device and the watercraft. The controller is configured to receive range information corresponding to a target distance between the watercraft and the wireless communication device. The controller is further configured to receive displacement data corresponding to an actual distance between the watercraft and the wireless communication device. The controller is further configured to compare the displacement data to the range information. The controller is further configured to determine an overboard condition based on the comparison of the displacement data to the range information. The controller is further configured to communicate an instruction to control the watercraft based on the overboard condition.

A rescue system for a watercraft includes: a control device provided in the watercraft; a portable device held by a person on board the watercraft and communicating with the control device; and a position detection device that detects a position of the watercraft. The control device detects a fall of the person from the watercraft based on a signal from the portable device, stores the position of the watercraft indicated by a signal from the position detection device when the fall of the person from the watercraft is detected as an overboard event detection position, and controls at least one of a propulsion device and a steering device of the watercraft based on the overboard event detection position and the current position of the watercraft such that a current position of the watercraft approaches the overboard event detection position.

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.
