Abstract: A marine drive assembly has a housing extending along a central axis and defining a gearbox section and a driveshaft section. A bevel gear assembly is housed in the gearbox section and has a first bevel gear rotatable about a central axis, a second bevel gear rotatable about the central axis, and a third bevel gear rotatable about a radial axis and operatively engaging the first bevel gear and the second bevel gear. A mounting flange is connected to and extends around at least part of the gearbox section. An inner shaft extends along the central axis and is operably connected to the first bevel gear for rotation in a first rotational direction about the central axis. An outer shaft is coaxially arranged with the inner shaft and operably connected to the second bevel gear for rotation in an opposite second rotational direction about the central axis.

Abstract: A marine propulsion system, supported by a strut, which comprises an inner propeller shaft supporting a first propeller adjacent a trailing end thereof, and the inner propeller shaft is connected to the drive shaft for receiving and supplying a first portion of torque to the first propeller as well as transfer thrust, generated by the first propeller, along the inner propeller shaft back to the drive shaft. An outer propeller shaft supports a second propeller adjacent a trailing end thereof, and the outer propeller shaft surrounds the inner propeller shaft. A planetary gear assembly receives a second portion of the torque and supplies the torque to the outer propeller shaft so that the second propeller rotates in an opposite direction to the first propeller. A portion of the planetary gear assembly is accommodated vertically above a flat end face of the strut for reducing hydrodynamic drag of the strut.

Abstract: A gearcase for a marine propulsion system has an input shaft rotatable about a central axis of rotation and an output shaft coaxially arranged with the input shaft. A clutch assembly is operable between a first clutch position and a second clutch position, wherein, when the clutch assembly is in the first clutch position, the input shaft is coupled to the output shaft for rotating the output shaft in a first rotational direction. When the clutch assembly is in the second clutch position a gear assembly operably connects the input shaft to the output shaft for rotating the output shaft in an opposite second rotational direction. The gearcase can be part of a marine propulsion system, such as an outboard motor for a mud boat. A method of transferring power in a gearcase and a marine propulsion system are also disclosed.

Abstract: A maritime drift control system comprising a vessel movement detection unit, for detecting an actual vessel speed and direction, and a vessel movement control unit with a drift controller for controlling operation of at least one propulsion device of a vessel. The maritime drift control system comprises a drift error generator for generating drift error signals depending on a predetermined speed limit and the actual vessel speed.

Abstract: The invention relates to improved methods of amplifying and optionally quantifying and/or identifying a plurality of selected nucleic acid molecules from a pool of nucleic acid molecules. A first round of multiplex amplification used where the amplification reaction is allowed to proceed to a point prior to that at which significant competition between amplicons for reaction components has occurred. This is the followed by a second round of amplification that typically includes a fluorescent reporter to allow for each of the selected nucleic acid sequences to be quantified. The methods are useful for the amplification and quantification of nucleic acids from a variety of sources, such as gene expression products, whereby many such products may be amplified and quantified from very limited samples and from degraded archival samples.

Abstract: Systems and methods are disclosed for transmitting a text/multimedia message over a bearer interface of a mobile network. A first network element of the mobile network, such as an MSC for a Mobile Terminated (MT) text/multimedia message or a BSS for a Mobile Originated (MO) text/multimedia message, receives a text/multimedia message. The first network element communicates with a second network element of the mobile network using a signaling interface (e.g., an IOS A1 interface) to select a bearer connection on a non-voice circuit-mode bearer interface (e.g., an IOS A5 interface), and routes the text/multimedia message to the second network element over the selected connection on the non-voice circuit-mode bearer interface. The first network element may also select a bearer connection on a voice bearer interface (e.g., an IOS A2 interface) and route the text/multimedia message to the second network element over the selected bearer connection.
