Two-wire circuits in new installations are limited to intercom and military field telephone applications, though these too are being supplanted by modern digital communication modes. To communicate in both directions in the same wire pair, conversion between four-wire and two-wire was necessary, both at the telephone and at the central office .
The Pershing II had a high-accuracy maneuverable reentry vehicle (MARV) equipped with a radar terminal guidance system, which allowed it to use the lower-yield W85 warhead. This warhead was derived from the B61 Mod 3 and utilized the same pit in the primary stage of the warhead, [ 4 ] but it has also been described as having a nuclear design ...
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
The value read from the map is offset by other environmental factors (such as coolant temperature). This corrected value is then used to meter fuel by pulse-width modulating the fuel injectors. Because each bank of the V8 feeds an exhaust line with its own oxygen sensor, the air/fuel ratio can be monitored and controlled for the banks ...
The W80 mod 0 (W80-0) used "supergrade" fission fuel, which has less radioactivity, in the primary in place of the conventional plutonium used in the Air Force's version. "Supergrade" is industry parlance for plutonium alloy bearing an exceptionally high fraction of Pu-239 (>95%), leaving a very low amount of Pu-240 which is a gamma emitter in ...
This line is intended for use with 2-wire circuits. Fig. 2. Balanced line in star quad format. This line is intended for use with 4-wire circuits or two 2-wire circuits. It is also used with microphone signals in professional audio. Fig. 3. Balanced line in DM quad format. This line is intended for use with 4-wire circuits or two 2-wire ...
The W85 heavy machine gun or QJC-88 vehicle mounted heavy machine gun is a gas-operated heavy machine gun designed in the People's Republic of China. It fires the Soviet-designed 12.7×108mm round. [3] The W85 was never accepted into the PLA service in its original configuration, only adopted as a vehicle mounted machine gun as the QJC-88.
