The binary signal is encoded using rectangular pulse-amplitude modulation with polar NRZ(L), or polar non-return-to-zero-level code. In telecommunications, a non-return-to-zero (NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage, while zeros are represented by some other significant condition, usually a negative voltage, with ...
The reason why bipolar encoding is classified as a return to zero (RZ) is that when a bipolar encoded channel is idle the line is held at a constant "zero" level, and when it is transmitting bits the line is either in a +V or -V state corresponding to the binary bit being transmitted. Thus, the line always returns to the "zero" level to denote ...
British Polar Engines is a manufacturer of diesel engines based in Glasgow, Scotland. The company has over seventy years' experience in the manufacture and supply of spare parts for diesel engines. The engine and company take their name from the engine supplied to Amundsen's Fram, from which he conquered the South Pole.

Publicly announced on 30 June 2017 as the "Pax Antarctica", the settlement between the International Polar Foundation and the Belgian government includes the Belgian government fully owning the base, the International Polar Foundation receiving contracts to operate the base for the next six years, and a cessation of all legal proceedings.

Polarization techniques have long been used in radio transmission to reduce interference between channels, particularly at VHF frequencies and beyond. Under some circumstances, the data rate of a radio link can be doubled by transmitting two separate channels of radio waves on the same frequency, using orthogonal polarization.
Polar alignment is the act of aligning the rotational axis of a telescope's equatorial mount or a sundial's gnomon with a celestial pole to parallel Earth's axis.
Polar Storm (also known as Pole Reversal) is a 2009 American-Canadian made-for-television science fiction-disaster-thriller film that was written and directed by Paul Ziller and was aired on the Sci-Fi Channel on March 28, 2009.
