But special back-surface mirrors can be eliminated, and the effect maintained, by another strategy entirely: If the front surface is textured into pyramidal shapes for antireflection, it bends all incident light in such a way that it strikes a polished, but otherwise untreated back-surface of th...
losses. A spring system may be very compliant by virtue of having considerable damping, but then it is not energy efficient. Prior art running shoes have this drawback. The term resilience as used herein means that damping is minimized, so energy efficiency is maximized. In summary, compliance...
When light propagating down a fiber core exceeds the critical angle created by the core/cladding interface due to tight bends in the fiber, light will leak from the core into the adjacent cladding and outer coating surfaces. Damage to the cladding or coating will occur if these surfaces are ...
A higher frequency results in smaller engines but also requires higher acoustic power and can lead to increased heat losses. • Stack material and geometry: The density, thermal conductivity, plate thickness, spacing between the plates, length, and position of the stack. The design of the ...
in a manner which is per se well known in the art. Some of the gas may also be lost through mufflers 28 by overpressurizing it compared to the gas in the mirror assemblies to provide an aerodynamic window. Such losses are replenished by the make-up gas supply. The use of bleeding ...
Based on this, it is the objective of the present invention to reduce the operating losses and in particular to increase the operating security of the energy routing device. A further objective of the invention is to reduce the construction and assembly labor. ...
the bend loss over the same 90-degree bend length might be closer to 1 dB at 1550 nm. At a shorter wavelength of approximately 1310 nm, these losses may be so small as to be indetectable. As such, longer wavelengths may be preferred to maximize the bend radius as to not induce excess...
A still further object of the present invention is the provision of a solar heat collector of the type above-indicated wherein radiation heat losses to the outside are minimized by the reflection of radiation attempting to pass in that direction back into the structure. ...
29. The heat exchange manifold of claim 28 wherein said plurality of platelets further defines a plurality of working gas conduits, said working gas conduits defined by a plurality of U-shaped bends, said U-shaped bends proximate said combustion chambers, wherein said working conduits transport ...
This experiment’s result shows that the “Schmitz theory” of substantial wind turbines applies to the smallest-scale wind turbines, but there is a sharp decline in the power generation at low wind speed because of frictional losses in internal electric resistance and the generator. Similarly, ...
