Abstract:
A launchable communication device for divers includes a flag, a flag operating assembly, and a receptacle. The flag is coupled to the flag operating assembly and is positionable between an extended position and a collapsed position to facilitate an opening and closing of the flag in order to communicate with others in the vicinity.
Abstract:
A marker buoy constructed of a main shaft extending vertically when in use and including a marker flag, a floating body, and a spool mounted to the main shaft.
Abstract:
Embodiments of the invention provide a water safety device used to increase participant visibility by passing water craft. The device is worn by the participant on his or her wrist and activated upon need at which time a flag is uncoiled and extended above the water. Upon conclusion of the need for visibility, the flag is replaced around the participant's wrist and ready for the next use.
Abstract:
A dive buoy/dry box assembly comprising a hollow canister-like main float assembly having a hinged latchable air-tight sealing lid, a collapsible marker flat and mast removably attached to the lid, a collapsible staff and ballast weight removably attached to the bottom of the float assembly and a buoy line storage reel detachably mounted surrounding the float assembly in a horizontal plane, the marker flat, mast ballast weight and staff all storable in said float assembly when collapsed.
Abstract:
Systems and methods for displaying a marine signaling device are disclosed. A flag coupled to a top section of a telescoping shaft includes a folding arm pivotally coupled to the top section that folds upward to gather the flag into alignment with the telescoping shaft. A housing couples to a boat and supports the shaft in the display configuration and receives the shaft in the storage configuration. As the shaft is retracted, the folding arm contacts an upper surface of the housing and gathers the flag into alignment with the shaft. A motor automatically extends/retracts the shaft based on detected tension on a tow rope mount of the boat or a tow rope coupled to the boat. A tension switch detects tension and activates the motor based on the detected tension. The tension switch may include arms that rotate in response to tension to activate a limit switch.
Abstract:
Disclosed is a life saving system, which includes an end-user unit carried on the lifejacket of the user in an aircraft or ship for providing a radio coordinates data of the end-user unit upon an accident subject to the operation of a global position signal receiver module and a starter, which starts the end-user unit when dipped in water or driven by the user, and a main unit carried by a lifeguard for searching the location of the end-user unit through the operation of a transmitter receiver module and a display.
Abstract:
The invention features a device for generating a plume of water, the device including a) a first side wall, b) a second side wall extending at an angle to the first side wall, the first side wall and the second side wall defining a tapered channel, the channel including i) a first end, ii) a second end, and iii) a longitudinal extent extending between the first end and the second end, c) a first flange extending at an angle to the first side wall, and d) a second flange extending at an angle to the second side wall.
Abstract:
Methods for monitoring windlass rotation are provided to determine the real time rate and length of rode release when anchoring a boat. The rotation can be monitored in real time using directional sound and/or electromagnetic radiation receivers and/or transmitters that can be in a module attached to the windlass. Another windlass module can monitor windlass rotation using micro-electromechanical systems (MEMS) components such as accelerometers, magnetometers, gyroscopes, and/or inertial measurement units (IMU) to sense motion and/or position.
Abstract:
Devices, systems and methods for real-time wave monitoring are described. One example system for real-time monitoring of wave conditions includes a plurality of buoys, wherein each of the plurality of buoys comprises a sensor array configured to continuously monitor one or more characteristics of the wave conditions, a transceiver configured to transmit, to a remote server, information corresponding to the one or more characteristics of the wave conditions over a wireless communication channel, and a tether that physically couples the buoy to an anchor, wherein the information from each of the plurality of buoys is combined with a user preference to provide a user with a message regarding the wave conditions in response to a user request, and wherein a duration between the user request and transmission of the information from each of the plurality of buoys is less than a predetermined value.
