Patent number: 6604479Abstract: A boat featuring an autopilot-based steering and maneuvering system. The steering system uses a specially integrated autopilot that remains engaged unless the operator is actively commanding the boat to change course. For example, in a boat in which steering is performed using a joystick, course changes can be effected simply by moving (e.g., twisting) the joystick. That movement automatically disengages the autopilot, allowing the operator to achieve the course change. When the operator has completed the course change and released the joystick, a centering spring returns it to a neutral position and the autopilot automatically reengages. In the improved maneuvering system, the autopilot is used for controlling the direction of a waterjet boat during very low speed (e.g., less than 4 knots) maneuvers, such as docking. The autopilot controls the steering system, e.g.Type: GrantFiled: October 24, 2002Date of Patent: August 12, 2003Assignee: The Talaria Company, LLCInventors: Shepard W. McKenney, Kenton D. Fadeley

Patent number: 6604508Abstract: A hydraulically activated fuel injection system uses a common rail that is maintained at relatively high pressure by a pump when the engine is running. During start-up, a volume reducer is used to pressurize the common rail until the pump can take over. A member of the volume reducer protrudes through one end of the common rail and is movable into and out of the common rail. When the ignition is activated, the member advances into the common rail causing the fluid volume to decrease and the pressure within the hydraulic system to increase, thereby allowing activation of the fuel injectors and starting the engine before the system pump is able to supply high pressure fluid to the common rail. Once the pump is able to sustain system pressure to the desired level, the member can retract to its original position.Type: GrantFiled: September 4, 2001Date of Patent: August 12, 2003Assignee: Caterpillar IncInventor: Darrel H.

Patent number: 6604515Abstract: A cooling apparatus (10) and method for a turbocharged internal combustion engine (12). The combustion air (16) exiting a turbocharger (18) is passed over an air-to-water intercooler (40) then over an air-to-air intercooler (42) for heat exchange with liquid coolant and with ambient air (32) respectively. During periods of low ambient air temperature, the combustion air may be directed through a bypass duct (80) around the air-to-air intercooler, and further, may be heated by the coolant in the air-to-water intercooler. A multi-speed fan (44) and/or shutters (48) may be used to control the flow of ambient air across the air-to-air intercooler. A cooling duct (68) provides a flow of ambient air to the fan motor (46) during periods of operation when the flow of ambient air over the air-to-air heat exchanger is restricted by the shutters. Coolant exiting a subcooler (28) has the lowest temperature in the system and is directed to a lube oil cooler (34) for engine lubricant cooling.Type: GrantFiled: January 16, 2002Date of Patent: August 12, 2003Assignee: General Electric CompanyInventors: Gregory A.

Patent number: 6604523Abstract: According to the invention, methods and devices for increasing cardiopulmonary circulation induced by chest compression and decompression when performing cardiopulmonary resuscitation are provided. According to one method, a pressure responsive inflow valve is coupled to a patient's airway. Chest compressions and chest decompressions are performed. During chest decompression the inflow valve prevents respiratory gases from entering the lungs until a certain negative intrathoracic pressure level is exceeded at which time the one inflow valve opens. In this way, the inflow valve assists in increasing the magnitude and duration of negative intrathoracic pressure during decompression to enhance the amount of blood flow into the heart and lungs. Further, the patient is supplied with a pressurized respiratory gas through the inflow valve when the inflow valve opens to ventilate the patient.Type: GrantFiled: May 11, 2001Date of Patent: August 12, 2003Assignee: CPRX LLCInventors: Keith G.
