| 20120095628 | SAFETY SYSTEM FOR MARINE VESSELS - There is elucidated a safety system for a marine vessel. The vessel includes two engines coupled to propellers for propelling the vessel through water. The vessel is provided with a digital anchor in communication with the two engines for maintaining the vessel substantially at a defined location when the anchor is activated. The safety system includes a sensor assembly coupled to a data processing assembly for sensing a region of said water at least partially surrounding the vessel for detecting one or more persons present in the region and for modifying operation of the digital anchor is response to the one or more persons being detected. The invention is of advantage in that the digital anchor is capable of responding to the one or more persons being present in the water and thereby reducing a risk of injury or loss of life when the digital anchor is employed. | 04-19-2012 |

| 20110144851 | SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR MONITORING OIL CONDITION - The present invention relates to a system, method, and computer program product for monitoring oil condition. In one embodiment, a marine powertrain is provided that includes a marine engine and a gear casing containing an oil and a gas. An engine speed sensor generates an output value, which indicates a speed of the marine engine. An oil sensor generates an output value, which indicates a condition of the oil. The condition of the oil is selectively monitored according to whether the marine engine is operating at a speed that is less than an engine speed threshold value, which denotes a speed of the marine engine at which the oil and the gas form an oil and aerated gas mixture. | 06-16-2011 |
