The mainstream types of chipless tags are digitally encoded and work at more than one millimetre range, like silicon chips. Their potential markets go beyond the lowest cost-highest volume potential markets because they have other attributes beyond cost.
or red shift. noun, Astronomy. 1. a shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth. Compare cosmological redshift, Doppler effect, gravitational redshift. Origin of redshift.
Drafts can also be conceived by low or high pressure regions. A low pressure region will attract air from the surrounding area, which will move towards the center and then rise, creating an updraft. A high pressure region will then attract air from the surrounding area, which will move towards the center and sink, spawning a downdraft. Updrafts and downdrafts, along with wind shear in general, are a major contributor to airplane crashes during takeoff and landing in a thunderstorm.
