In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to ...
A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
Most DC-to-AC converters (power inverters), most AC/AC converters, the DC-to-DC push–pull converter, isolated DC-to-DC converter [2] most motor controllers, and many other kinds of power electronics use H bridges. In particular, a bipolar stepper motor is almost always driven by a motor controller containing two H bridges.
Camera PCB with a 1/3" Sony CCD Camera modules may include a lens (shown at top), an image sensor (shown at bottom), and supporting circuitry. NC393 multisensor camera kit, for developers. A camera module is an image sensor integrated with a lens, control electronics, [1] and an interface like CSI, Ethernet or plain raw low-voltage differential ...
The W-series laptops were introduced by Lenovo as workstation-class laptops with their own letter designation, a descendant of prior ThinkPad T series models suffixed with 'p'. [2] The W series laptops were launched in 2008, at the same time as Intel Centrino 2, marking an overhaul of Lenovo's product lineup. [ 2 ]
The first 35 mm SLR to achieve such a shooting speed was Nikon's F High Speed Motor Drive camera, first developed for the 1971 Chicago Photo Expo with 7 fps. [4] To enable this speed and allow the photographer to more easily track the moving subject, this camera used a fixed, semi-transparent pellicle mirror instead of a moving mirror. Later ...
A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque , it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
Another way of changing speed of a direct current motor is to change the voltage applied to the armature. An adjustable-speed motor drive might consist of an electric motor and controller that is used to adjust the motor's operating speed. The combination of a constant-speed motor and a continuously adjustable mechanical speed-changing device ...
