Advanced Operating System
... The RTOS considers a process to be in one of three states: waiting, ready, and executing. In a uniprocessor system, only one process can be executing at any time. Some processes may be waiting for data or other events. Processes which are not blocked for external events but are not currently executi ...

... For a hybrid motor, if we apply a voltage to each of the windings we will control the direction of current, and thus, polarity at each stator. At any given time, one set of stators (A or B) will be aligned perfectly with the rotors teeth and the other set of stators will be misaligned. By switching ...

Alternating current
Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas in direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage.AC is the form in which electric power is delivered to businesses and residences. The usual waveform of alternating current in most electric power circuits is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. These types of alternating current carry information encoded (or modulated) onto the AC signal, such as sound (audio) or images (video).
