Most of the work going on globally in integrated polymer components is in the areas of switches, attenuators , filters, modulators, lasers, and amplifiers.
Motorola believes that a combination of switchable attenuators and increased public safety signal strength in weak signal areas will mitigate the interference being experienced to a large extent.
Unlike a volume potentiometer, an attenuator ensures that the sound quality remains constant: the left and right imaging doesn't shift with different volume settings.
And a unique glass-reinforced-nylon manifold is molded in halves, joined together by ultrasonic welding, then cloaked with a form-fitting foam noise attenuator .
The multiplexer with variable optical attenuator is another design that has pulled together several functions.
