Abstract:
A system for a marine vessel operating in a body of water includes a trimmable marine device coupled to and movable with respect to the vessel and an actuator that raises and lowers the marine device. A control module is in signal communication with the actuator. A GPS receiver determines a current and/or predicted global position of the vessel, and a processor accesses a memory storing bathymetry data and retrieves a water depth corresponding to the vessel's current and/or predicted global position. The control module compares the water depth to a depth of the marine device based on the marine device's current position. The actuator raises the marine device in response to the control module determining that the water depth is not enough to accommodate the depth of the marine device at the current position without potential collision between the marine device and the body of water's bottom.
Abstract:
A navigation assist system having a plurality of navigation assist apparatuses installed on small boats like motorboats each fitted with an outboard motor to be able to navigate in a predetermined water area, and a server placed on land to communicate with the navigation assist apparatuses. Each of the navigation assist apparatuses detects a trim-up position of the outboard motor, adds the position to a danger level data downloaded from the server unit, and alerts an operator concerned when the boat approaches a region whose danger level is great.
Abstract:
A variable volume raft containing adjustable ratio and amounts of air and or water. The buoyancy and ballast of the raft are routinely adjusted to accommodate additional occupants and changing weather conditions. A manual pump can be the primary or back up source for initial inflation. The torque pump twisted by hand or amplified by a lever arm generates air pressure for maintenance and repairing deflating lacerations at sea. The pumps collector gathers and pressurizes rain water for drinking in one chamber while pressurizing sea water as a stabilizing ballast in another chamber. A double hull or full floor chamber allows huge variations in buoyancy or ballast as dictated by changing needs for stability versus mobility. A compressed liquid or two-part foam confers puncture resistance to a portion of the raft. A thrown self-righting manual air horn, worn water-activated air horns and water activated transmitted signals, mark the site for rescuers.

Abstract:
A personal flotation vest device is provided that includes front flotation members that work in conjunction with a buoyant neck stabilizing member extending from the top of the back of the vest portion, and a buoyant buttocks support member extending from the bottom of the back of the vest portion, to provide a comfortable and stable platform for supporting the user in a substantially horizontal position. Adjustable fasteners allow a comfortable fit as the vest is donned. In addition, a whistle is attached to the vest by means of a lanyard for emergency use. A retraction device for retrieving and storing the extended lanyard is also provided. To avoid the onset of dehydration a pocket is provided for storing a fresh water container.
Abstract:
Reconfigurable vehicles, methods of configuring modular vehicles are provided. Vehicles may have modules that may be coupled to the vehicle at discrete positions and at discrete angles. Configurations for the modular vehicles may be further determined automatically depending on desired vehicle characteristics. Modular vehicles may be configured manually, and a predicted vehicle characteristic may be determined.
Abstract:
The present invention is directed to a passive ascent rate monitor that is operable to determine a diver's rate of ascent and generate a signal indicative of the determined ascent rate. In one embodiment, the ascent rate monitor outputs graduated audible signals that correspond to a plurality of ascent rate ranges. In another embodiment, the ascent rate monitor generates private audible ascent rate signals allowing a diver to determine their own ascent rate without necessarily outputting signals that may be heard by and/or interfere with their dive partners.

Abstract:
The present invention relates to a distress/safety device for a small watercraft (10). Specifically, the present invention relates to a distress signal that is given when a rider (12) is no longer present on the watercraft (10). The distress signal is provided by a light (44), by an audible signal, or by an electronic transmission to a receiver. The distress/safety device is in the form of a circuit which remains open as long as a key (52) is inserted in the alarm trigger slot (46) on the watercraft (10). The key is attached by lanyard or cable to an individual driver or passenger of the watercraft (10). Should the individual be displaced from the watercraft (10), the lanyard pulls the key (52) free from the kill switch (40) or alarm trigger slot (46) closing the circuit and triggering the alarm. Alternatively, the kill switch (40) is activated when the rider is displaced from the watercraft (10), thus activating the alarm system which is integral with the ignition. The types of distress alarms may be combined so that more than one type is given in response to a fallen rider.
