The housing is configured to attach to an existing HVAC system of the vehicle. | 08-27-2009 |
20090222155 | Propulsion system - A system for automatically controlling the speed of a battery powered electric propulsion motor driving a shaft connected to a propeller located on a sailing vessel. The system includes a user interface for selecting either a neutral, a regeneration or a forward thrust operating mode. The system also includes a controller configured to receive input from a motor speed sensor and a motor current sensor. The controller adjust the speed of the motor to the correct motor speed. The controller is configured so that in the neutral mode the correct motor speed is the speed required to substantially eliminate thrust on the shaft. | 09-03-2009 |
20090261599 | Power generation system - A power generation system including an engine and an electrical generator driven to rotate at rotational speed by the engine. The generator is configured to supply an adjustable amount of required electrical power having a voltage and a current to at least one electrical load. The system also includes a controller configured to adjust at least one operating parameter of the engine in order to maximize efficiency of the system. The system efficiency is a measure of the combined operation of generator and engine and load for a given load condition. The controller is configured to maximize system efficiency based only upon the required electrical power being supplied by the generator. The controller is configured so that the controller does not independently consider any one of the rotational speed, the voltage or the current being supplied by the generator when adjusting the at least one operating parameter. | 10-22-2009 |
20090269994 | Propulsion system for a marine vessel - A marine vessel includes an exterior component fitted to a hull of the marine vessel and a propulsion module configured to be received by the exterior component. The propulsion module includes a power source configured to drive a propeller; a shaft configured to couple the power source and the propeller. The module includes a housing configured to store at least the power source and a portion of the shaft. | 10-29-2009 |
20100094490 | POWER GENERATION SYSTEM FOR MARINE VESSEL - A marine vessel power generation and propulsion system including a control system. The system includes a plurality of generator sets, each generator set including an engine configured to drive an electrical generator and wherein each generator set is configured to supply electrical power to an electrical bus.
