A system and method for monitoring a spatial position of a mobile transmitter is provided. In particular, the mobile transmitter may be attached to or included in an object of interest. By analyzing the signal strengths of radio frequency signals emitted by the transmitter, a spatial position of the mobile transmitter can be determined, and it is possible to detect whether or not the spatial position of the mobile transmitter is outside an allowable area. By applying the monitoring of the spatial position to a radio frequency system on a vessel, a reliable man-over-board detection can be achieved.

Systems and processes for initiating a rescue, using peer-to-peer distress alert systems, are described. An exemplar process of initiating, from a distressed vessel, a recue includes: (i) generating an outgoing distress signal that includes a distress signal and distressed vessel location information; (ii) broadcasting the outgoing distress signal to one or more potential rescue vessels located away from the distressed vessel; (iii) receiving, from one or more of the potential rescue vessels, one or more outgoing rescue signals, each of which includes potential rescue vessel location information; (iv) of identifying, using the potential rescue vessel location information from one or more of the potential rescue vessels and vessel location information of the distressed vessel, one or more rescue potential rescue vessels that are suitable for rescuing the distress vessel; and (v) transmitting, from the distressed vessel, a confirmation rescue signal to each of the potential rescue vessels that are suitable for rescuing the distress vessel.

The smart inflatable swimwear gets involved in the swimwear technology area. The smart inflatable swimwear is composed of the body, gasbags, air tubes, gas cylinder, gas needle, prober, bandages, power cord and caution light. The gasbags are mounted on both sides of the front side of the body of the described swimwear which also has gasbags on the middle of the back side. The gas cylinder is mounted on the body of the swimwear on the back side under the described gasbags. The described gas cylinder is connected to the gasbags on the back side through the air tube. The described gasbags on the back side are connected to the ones on the front side through the air tube.

A vessel control system for a marine vessel propelled by at least one propulsion device includes a wireless lanyard system including at least one fob worn by an individual on the marine vessel and a helm transceiver at a helm area of the marine vessel configured to receive radio signals from the at least one fob. A controller is configured to detect, based on communications between each of the at least one fob and the helm transceiver, that each of the at least one fob is present on the marine vessel. A missing fob is detected if at least one of the fobs is no longer detected at the helm transceiver, and then a man overboard event is generated. The vessel control system is configured to automatically activate one or more search assistance functions based on the man overboard event.

An apparatus and method for inflating an inflatable object, such as a floatation device. The inflation apparatus includes a component with a primary opening, the primary opening sized and shaped to accept air from an air source, such as a hair dryer. A secondary opening on an inflation adapter is sized and shaped to be in communication with a valve opening on the inflatable object.

An inflator including in combination, an inflator body having at one end an input for receiving the neck of a gas cartridge, a manifold assembly intended to be fluidly connected to an inflatable, a combination automatic and manual actuator assembly including a spring-loaded actuator including a pierce pin for fracturing a frangible seal of the gas cartridge, a bobbin with a dissolvable pill that retains the spring-loaded actuator in a cocked position by an annular ring seat that engages the bobbin and a hood connected onto the end of the inflator body, the hood including an inwardly-extending tab that engages the actuator to securely retain the hood onto the end of the inflator body by means of the inwardly-extending tab being grasped by the forked end of the actuator.

An inline for an inflatable assembly may comprise a first end defining a primary gas inlet and a second end defining a primary gas outlet. An internal surface may define a flow path extending from the primary gas inlet to the primary gas outlet. An orifice may be located between the first end and the second end. The orifice may be defined, at least partially, by a radial wall extending from the internal surface to the external surface. The orifice may be configured to entrain ambient air with a primary gas flowing from the primary gas inlet to the primary gas outlet.
