Airflow driven electrical generator for a moving vehicle
InactiveUS6857492B1Reduce resistanceImprove efficiencyAuxillary drivesWind motor supports/mountsMobile vehicleElectricity
An apparatus for generating electricity in a moving vehicle utilizes a low drag spirally shaped fin mounted longitudinally on a cylindrical component of a generator which receives air from a vent as the vehicle moves through air. The vent includes structure for bypassing at least a portion of the airflow through the vent as the vehicle moves faster through the air. The airflow causes the cylindrical member to rotate causing the generator to generate electricity. The rotating cylindrical member may be provided with magnetic material.

Electronic method of controlling propulsion and regeneration for electric, hybrid-electric and diesel-electric marine crafts, and an apparatus therefor
InactiveUS20100125383A1Easy to manufactureTracking operationHybrid vehiclesAuxillariesPropellerEngineering
A method of programming and setting parameters for a computer unit that regulates the interface between the operator of a marine vessel and the vessel's electric generation and propulsion systems. The invention describes the regulation of energy producing devices, energy storage devices and drive motors and propellers in both propulsion and regeneration modes. This invention simplifies and automates most of the operation of marine electric, hybrid electric, or diesel electric propulsion because the only controls requiring operator intervention are three generator modes: OFF, AUTO and ON, an alarm, an override switch and one or more throttle(s). This helm control can be duplicated in different areas of the vessel. All automatic modes required to regulate forward movement, reverse, emergency power, zero drag, propeller freeze and regeneration are all controlled by a logic using a combination of generator mode, the position of the throttles, the speed and the stored parameters of the vessel.

Event sensor
InactiveUS20080243321A1Maintenance free and accurateSpeed controllerInstruments for road network navigationDriver/operatorWater flow
An automatic timing measurement system that provides a measure of time of passage of a watercraft through a prescribed course. Algorithms based on inertial or other estimates augmented by GPS speed / position measurements are used to track position of a watercraft. Said position estimates are used to allow the locations of prescribed courses to be mapped and memorized. Algorithms are then used to allow the apparatus to automatically detect passage of a watercraft through mapped courses for the purpose of measuring and reporting time of passage of said watercraft past key points in said course, and for modifying the behavior of the speed control portion of the apparatus if necessary at certain points in the mapped course. A measure of accuracy of driver steering can be provided along with the ability to automatically steer the watercraft through the course if “steer-by-wire” mechanism is available. GPS speed control is augmented with a secondary velocity measurement device that measures speed over water resulting in an optional user selectable real-time compensation for water current. Furthermore, GPS is used as the key input to produce boat speed-based pull-up profiles.

A short-term planned route from a start position that is a ship position at a first time up to an end position that is the ship position at a second time is designed based on a planned route, an estimated encounter marine phenomenon information, operation performance information measured on a ship, and a hull motion model of the ship, the estimated encounter marine phenomenon information being measured on the ship based on actually encountered marine phenomenon information. The short-term planned route makes a first evaluation function optimal, the first evaluation function containing: an index indicating an influence of a fluctuation portion between a planned position that is a ship position planned at the second time on the planned route and the end position; a fuel consumption index when the ship sails along the short-term planned route; and a safety index when the ship sails along the short-term planned route.

Navigational planning and display method for the sailor's dilemma when heading upwind
ActiveUS20090287409A1Convenient for calculationQuick fixDigital data processing detailsPosition fixationSimulationVelocity made good
A method is disclosed that resolves a long-standing seafaring problem of how close to the wind to sail. Sailboats need a convenient way to determine the optimal heading to minimize the Tacking Time to Destination (TTD). Unlike Velocity Made Good (VMG), the method disclosed here allows route planning before the trip, predicts travel time on different points of sail, allows comparison of the optimal tacking routes, and also plots the different routes so that it is inherently obvious that a particular tacking angle is longer and more off-course but will arrive sooner because of the speed on that heading. These principles can be implemented with manual dials that define the distance and speed, to calculate the relative or actual travel time on a leg without using electronics. Software is also described that visually illustrates the current and optimal headings by calculating Tacking Time to Destination before departure.
