To access the inexhaustible energy source like seas and oceans we need to learn how to convert its wave motion to the customized power for our ships, for our existing littoral settlements and our future ocean settlements. Here is an attempt to develop method of the conversion the wave energy to power with floating means based on a gyroscope strong capability to resist against the outer force moment trying to tilt it to any side.The gyroscope is used as the fulcrum torque dynamic supporting instead traditional static base used in the issued devices. Alternate force moment created by the waves and transmitted to the gyroscope (via the floating body and the wave energy converter) inducts alternative gyro precession so as the gyroscope axis hesitates about mean position. This is important because it allows the gyroscope to keep dynamic fulcrum torque in unlimited time.The few gyroscope precession control devices and methods have been developed to compensate other reasons enforcing the mean gyro axis to drift from initial plumb.Also here are developed the new ship architecture with the separated floating gyro section. The wagging propulsor driven by the pitching and with strokes amplified by the fulcrum gyro section, the spring moment generator for the gyroscope drift compensation, non gyroscope floating power station able to derive, convert, accumulate and transmit wave energy to consumer also have been developed here.

An improved method and system for layering RPC communications on top of an HTTP transport. An RPC data stream of individual request/reply packets is mapped to HTTP primitives, and RPC requests are mapped to one large, HTTP, POST-like request (IN channel). Corresponding replies are mapped to another large, HTTP, GET-like request (OUT channel).
