A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
[2] [20] The first use of a PDK in competition was the 1985 Porsche 962 C Le Mans racing car, which won the World Sportscar Championship in 1986. [2] [21] The PDK transmission was also used in the 1985 Audi Sport Quattro S1 Group B rally car. [7] [22] The first mass-production passenger car to use a DCT was the 2003 Volkswagen Golf R32.

Although video coding formats such as H.264 are sometimes referred to as codecs, there is a clear conceptual difference between a specification and its implementations. Video coding formats are described in specifications, and software, firmware , or hardware to encode/decode data in a given video coding format from/to uncompressed video are ...

Illustration of the implicit even/odd extensions of DCT input data, for N=11 data points (red dots), for the four most common types of DCT (types I-IV). Note the subtle differences at the interfaces between the data and the extensions: in DCT-II and DCT-IV both the end points are replicated in the extensions but not in DCT-I or DCT-III (and a ...
The average manual car driver takes between 500 ms and 1 s to perform vertical gear changes (i.e. 1st-2nd, 3rd-4th, 5th-6th) and 1 - 2 s to perform horizontal gear changes (i.e. 2nd-3rd, 4th-5th). Shift time is also dependent on gear throws (distance between gears), ease of movement, ergonomics of the gear stick , and gearbox condition.
[2] [3] TC-SST also works in conjunction with Mitsubishi's S-AWC system. [6] The operation of TC-SST is smoother than that of a conventional automatic transmission because it uses clutches instead of a torque converter to transmit power. [4] The key to the system's operation is in the electronic and hydraulic controls. TC-SST can select two ...
The General Instrument/Motorola DCT2000 is a cable box used for watching TV by way of digital cable. These set-top boxes were popular in the late 1990s up until the mid to late 2000s, when the adoption of more sophisticated successors, namely those set-tops with the ability to record live programming began.
