    摘要: Variable behaviour control mechanism with a variety of motion characteristics, the mechanism comprising means to measure a plurality of motion characteristics and to activate systems when a threshold of the motion characteristics is reached. The mechanism described is, for example, a vehicle seat belt and the mechanism minimises or prevents unwanted activation of line extension or retraction of the seat belt. A first mechanism is described where activation occurs between at least one primary system and at least one secondary system when a combination of the sensed motion characteristics achieves a threshold. A second mechanism is described where activation occurs between at least one primary system and at least one secondary system when at least one sensed motion characteristic achieves a threshold, the threshold being modified based on at least one further motion characteristic. A method of use of the above mechanisms is also described.

    摘要: One of the challenges of rooftop wind turbines is that the building causes turbulence and updrafts and can create a blockage to the wind at rooftop level. That means lower speed and higher turbulence wind hitting the turbine and less power output. Prior art solutions consisted of elevating the blades of rooftop turbines or making the updraft hit the blades. Creating structures that separate the turbulence of the air below roof level from the oncoming and higher velocity linear wind above roof level, where the turbine is located, can decrease slowing of the rooftop level wind stream and enable the blades to be placed closer to roof level, thereby saving construction costs and roof weight. It is ideal to combine these improvements with a vertical axis wind turbine.

    摘要: The invention provides a method for computational fluid dynamics and apparatuses making enable an efficient implementation and use of an enhanced jet-effect, either the Coanda-jet-effect, the hydrophobic jet-effect, or the waving-jet-effect, triggered by specifically shaped corpuses and tunnels. The method is based on the approaches of the kinetic theory of matter, thermodynamics, and continuum mechanics, providing generalized equations of fluid motion. The method is applicable for slow-flowing as well as fast-flowing real compressible-extendable fluids and enables optimal design of convergent-divergent nozzles, providing for the most efficient jet-thrust. The method can be applied to airfoil shape optimization for bodies flying separately and in a multi-stage cascaded sequence. The method enables apparatuses for electricity harvesting from the fluid heat-energy, providing a positive net-efficiency. The method enables efficient water-harvesting from air. The method enables generators for practical-expedient power harvesting using constructive interference of waves due to the waving jet-effect.
