Power scaling — of a laser is increasing its output power without changing the geometry, shape, or principle of operation. Power scalability is considered an important advantage in a laser design.Usually, power scaling requires a more powerful pump source,… … Wikipedia
Power steering — helps drivers steer vehicles by augmenting steering effort of the steering wheel. It does this by adding controlled energy to the steering mechanism, so the driver needs to provide only modest effort regardless of conditions. In particular, power … Wikipedia
