NLS-Glossary

Dipolar relaxation equation describes the time response of the induced dipole moment per molecule in a dipolar material in the presence of a time dependent applied field.           The response of the dipoles depends on their relaxation time which is mean time required to dissipate the stored electrostatic energy in the dipole alignment to heat through lattice vibrations or molecular collisions.

Dipole relaxation (dielectric resonance) occurs when the frequency of the applied ac field is such that there is maximum energy transfer from the ac voltage source to heat in the dielectric through the alternate polarization and depolarization of the molecules by the ac field.

The stored electrostatic energy is dissipated through molecular collisions and lattice vibrations (in solids). The peak occurs when the angular frequency of the ac field is the reciprocal of the relaxation time.

A variety of processes that are used to mark barcode symbols directly on a part rather than on a label, frequently used in manufacturing industries. Techniques include laser engraving, chemical etching, and dot peen marking.

When goods are shipped directly to a store, the container marking specifications are usually different from those required when shipping to a distribution center.                     

Having intercharacter spaces. In a discrete barcode, each character stands alone and is separated from the next by an intercharacter space or gap.
