the transmission of communication signals across utility powerlines or existing home wiring Frequencies may range from 8 kHz to 200 kHz and above and power levels are normally low (in the 1 to 20 watt range) The advantages of these systems include their ability to send signals over very long transmission lines (more than 100 miles) and their reliability However, they are limited in the amount of information they can transport because of narrow bandwidths Their low-frequency signals are severely attenuated by capacitor banks and transformers and can be overcome
Programmable Logic Controller Also know as a programmable controller, these devices are used for machine control and sequencing

Rolls-Royce PLC
British manufacturer of aircraft engines and propulsion and power systems and, for much of the 20th century, a maker of luxury automobiles. Charles S. Rolls, a pioneer motorist and aviator, and Henry Royce, an engineer and carmaker, incorporated Rolls-Royce Ltd. in 1906. The firm's handsome, immaculately engineered cars included the Silver Ghost (introduced 1906 as "40/50 hp" model), a series of Phantoms (1925), the Silver Dawn (1949), Silver Cloud (1955), Silver Shadow (1965), and Silver Seraph (1998). In 1931 Rolls-Royce acquired Bentley Motors Ltd., another maker of fine cars. Rolls-Royce also developed a series of notable piston and jet aircraft engines, beginning with the Eagle (1914); eventually its turbine-engine operations accounted for the largest part of its sales. A fixed-price contract with Lockheed Aircraft (see Lockheed Martin Corp.) to produce an engine for its L-1011 TriStar jetliner drove Rolls-Royce into bankruptcy in 1971. It was split into two companies: its jet-engine division was taken over by the British government and later privatized as Rolls-Royce PLC, while its automobile operations were restructured into Rolls-Royce Motor Holdings Ltd. and privatized. The latter was acquired in 1980 by Vickers Ltd., which sold it to Volkswagen AG in 1998 as part of a novel agreement in which BMW AG would take over the manufacture of cars with the Rolls-Royce name in 2003, while Volkswagen retained the Bentley line
