Launched in 2004, IGN reported "exponential growth in sales" since that time. It offered over 3,000 titles through relationships with more than 300 game publishers. [2] [3] Direct2Drive sponsored a $10,000 award at the Independent Games Festival called the D2D Vision Award, which "celebrates independent developers exemplifying innovation in design coupled with excellence in game-play".

A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device (such as the drive wheels of a vehicle) without involving any intermediate couplings such as a gear train or a belt. [1] [2] [3] [4]
Issues, quality, and performance indicators of direct-drive wheels, and of sim racing wheels in general, include detail and fidelity of force feedback, smooth torque transmission, nearly-zero backlash, rotary encoder resolution, clipping, dynamic range, torque ripple, [2] cogging torque, [10] drivers and digital signal processing with control electronics, [2] [11] signal filtering, [8 ...
Direct drive is the most efficient form of fan drive since there are no losses converting from the motors rotational speed to the fan's. Some electronics manufacturers have made centrifugal fans with external rotor motors (the stator is inside the rotor), and the rotor is directly mounted on the fan wheel (impeller).

With a direct-drive extruder, the motor pushing the filament is installed by the hotend and pushes the filament directly into the nozzle. Direct-drive designs have several advantages, and typically give better extrusion, faster retraction, are able to print more types of filaments, and can use a smaller and lighter motor due to the short distance to the nozzle.

Direct drive, brushless DC linear motors consist of a slotted stator with magnetic teeth and a moving actuator, which has permanent magnets and coil windings. To obtain linear motion, a motor controller excites the coil windings in the actuator causing an interaction of the magnetic fields resulting in linear motion. [ 19 ]
The new version of the ANSI standard, AT Attachment Interface with Extensions ATA-2 (X3.279-1996), was approved in 1996. It included most of the features of the manufacturer-specific variants. [21] [22] ATA-2 also was the first to note that devices other than hard drives could be attached to the interface: 3.1.7 Device: Device is a storage ...
