Patent CA-2531708-A1 (CA)
Title: Modular system for generating electricity from moving fluid
Inventor: PETROUNEVITCH EDOUARD
IPC: F03B13/12
Filed: 2006-01-05
Abstract: A modular system for producing electricity from the channel, river, ocean or tidal water currents and wind is disclosed. The embodiments of the system comprise a set of interconnected modules. Each module contains a fluid flow energy converter positioned in a protecting housing. A converter consists of a vertical axis underwater hydro-turbine or wind turbine, connected to the electrical generator. The turbine is essentially a paddlewheel having an arrangement of attached paddles with mutually perpendicularly oriented asymmetric blades that are fixed to the poles at both ends. Such orientation of blades provides a positive feedback minimizing the blades' friction while maximizing a drag force and maximizing the turbine's efficiency. The electrical generator transforms the rotational energy of the turbine into electricity. An array of modules may be arranged side by side, thus providing versatile configurations of submersible hydroelectric or wind power systems, which are inexpensive to build, install and maintain.

Title: Coupling structure for cylindrical resonators
Inventor: TSCHERNITZ MAXIMILIAN
IPC: H01P1/213
Filed: 2004-10-08
Abstract: The invention relates to a filter module suitable for the filtering of electromagnetic waves, comprising a dielectric cylindrical resonator (1) and one or more lines (2, 3), which supply or draw off electromagnetic waves to or from the dielectric resonator (1), whereby the lines (2, 3) terminate in a contacting structure (4, 4a, 4b). According to the invention, the resonator (1) has a variable separation from the lines (2, 3), whereby the separations may be conceived in both the negative as well as alternatively in the positive longitudinal direction (z-axis) of the resonator (1). The transmitted signal power may be significantly increased in an advantageous manner relative to conventional coupling structures by means of the above. The above is particularly suitable for application in oscillator circuits with operating frequencies above 18 GHz, such as typically find increasing application in environment systems of a motor vehicle such as Lane Departure Warning (LDW), Blind Spot Detection (BSD) or Rear View Detection.

Title: A hydroelectric powerplant
Inventor: WILLIAM HERBERT LEHMAN
IPC: F03B17/06
Filed: 2004-01-21
Abstract: A powerplant for use in high head applications (dams) which allows marine animals (fish, otters, turtles, etc.) to swim safely from one side of the dam to the other. The turbine blades which take energy from the water to produce electricity have a large hole through their center. They are arranged one behind the other in such a way that the velocity of the water is decreased as it passes through each blade. The large holes through the center of the turbine blades and the decreasing of the water flow, while increasing the amount of energy produced, will allow marine life to easily swim back and forth through the dam.
