Boeing granted patent for force field
This month, Boeing was granted a patent for generating force fields that keep shockwaves from harming military vehicles. The Boeing Company's patent, "Method and system for shockwave attenuation via electromagnetic arc," was filed in May 2012. "The idea is to harness electrical energy to stop or slow down the shockwaves created by explosions, which can do just as much damage as shrapnel." Boeing's plan would be to "marry a rapid explosion sensor with an arc generator to protect targets like military vehicles." Laser sources send out high-intensity laser pulses in the direction of the explosion. The laser pulses ionize the air to form a laser-induced plasma channel." The channel differs from the ambient air in density, temperature and composition. The result would be a buffer zone- different temperature, air density and other characteristics would reflect, refract, absorb and deflect at least a portion of the shockwave.
- In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water.
Was there some problem with saying "Boeing gets patent for a shockwave attenuation system?"So it's not force nor field. It is a system for damping a shockwave.
I hope that pipedot readers can handle the big words. And for those that can't, I hope they don't submit articles.
