Abstract: An electrosurgical medical device and method for creating thermal welds in engaged tissue. In one embodiment, at least one jaw of the instrument defines a tissue engagement plane carrying a conductive-resistive matrix of a conductively-doped nonconductive elastomer. The engagement surface portions thus can be described as a positive temperature coefficient material that has a unique selected decreased electrical conductance at each selected increased temperature thereof over a targeted treatment range. The conductive-resistive matrix can be engineered to bracket a targeted thermal treatment range, for example about 60°C, to 80°C., at which tissue welding can be accomplished.; In one mode of operation, the engagement plane will automatically modulate and spatially localize ohmic heating within the engaged tissue from Rf energy application-across micron-scale portions of the engagement surface. In another mode of operation, a conductive-resistive matrix can induce a "wave" of Rf energy density to sweep across the tissue to thereby weld tissue.

Abstract: A fault-tolerant node for synchronous heterogeneous database replication and a method for performing a synchronous heterogenous database replication at such a node are provided. A processor executes a computer program to generate a series of database transactions to be carried out at the fault-tolerant node. The fault-tolerant node comprises at least two relational database management systems, each of which are different relational database management system products, each implementing snapshot isolation between concurrent transactions. Each system comprises a database and a database management component. For each database transaction, operation instructions are provided concurrently to each of the systems to carry out operations on their respective databases and to provide respective responses. The responses generated by the systems either comprise an operation result or an exception. Only one of the systems is configured with a NOWAIT exception function enabled, which returns an exception when it is detected that two or more concurrent transactions are attempting to modify the same data item. The other systems are configured with the NOWAIT exception function disabled. The fault-tolerant node detects that two or more concurrent transactions are attempting to modify the same data item, and ensures that all systems apply the same order of modification of the data item by the concurrent transactions.

Granted: 1987-07-08
Abstract: In a method for controlling the propulsion machinery in a ship having a variable-pitch propeller, the ship's speed is first adjusted to a value within a predetermined interval containing a desired value of the speed. This adjustment is effected by changing the number of revolutions of the propulsion machinery and the propeller pitch, whereupon the number of revolutions and the pitch are changed, while maintaining the speed within the said interval. For each change in the number of revolutions and the pitch, it is checked whether the change has resulted in an increase or a cutdown in fuel consumption. These changes are effected until a combination of the number of revolutions and the pitch is attained, which provides for minimum fuel consumption in the propulsion machinery.
