Apparatus for measuring the lateral yarn density distribution of a yarn uses selected radiation in the X-ray spectrum wavelength. Radiation absorption is determined in a number of narrow planes across the yarn and in two or more rotational orientations. The measuring takes place without any damage t.....

Ultra-precision freeform surfaces are important to the development of complex and micro-optical-electro-mechanical devices used in many photonics and telecommunication products such as F-theta lenses for laser printers. These surfaces are complex and large scale surface topologies with shapes that g.....

A tool that can screen bacteria for .beta.-lactamases against a panel of various antibiotics is desirable. A biosensor incorporating an indicator molecule into .beta.-lactamases may achieve this purpose, but it requires that the attached indicator molecule must not impair the binding affinity of the.....
