Being a computer science or electrical engineering student, you probably have assembled a PC before. You may have gone out to purchase the motherboard, CPU (central processing unit), memory, disk drive, video card, sound card, and other necessary parts, assembled them together, and have made yourself a state-of-the-art working computer.

Intro to Mechatronics - Sensors hand-outs

Integrated manufacturing uses computers to connect physically separated processes. When integrated, the processes can share information and initiate actions. This allows decisions to be made faster and with fewer errors.

While these guidelines apply to the majority of installations, certain electrically harsh environments may require additional precautions.

In this chapter, we will look at how digital circuits are implemented. As you know, transistors are the fundamental building blocks for all digital circuits.

The discrete time control of a three phase 4 wire PWM inverter with variable DC link voltage for simultaneously supply of three phase and single phase load in transformerless stand alone photovoltaic application with battery energy storage (BES) and LC output filter is described.

Originated in WWII for just that purpose - a way for our secondary radars to identify U.S. aircraft from enemy aircraft by assigning a unique identifier code to U.S. aircraft transponders.

In the early 1970's, Hewlett-Packard came out with a standard bus (HP-IB) to help support their own laboratory measurement equipment product lines, which later was adopted by the IEEE in 1975. This is known as the IEEE Std. 488-1975.

Abstract--.This paper describes the City of Naperville’s migration from a traditional SCADA system to an integrated SCADA and Substation/Distribution Automation System. The paper will examine:

ACCEPTABLE DEGRADATION - The allowable reduction in system performance. For a fire control radar, the acceptable degradation is usually expressed as a reduction in range; for example, the maximum lock-on range might be degraded by 25 percent without loss of essential defense capability.

In industrial automation, fuzzy logic technologies enable the efficient and transparent implementation of human control expertise.

Figure 1, which follows, depicts the electromagnetic radiation spectrum and some of the commonly used or known areas.

The radiation patterns of the antennas presented in the previous section are for antenna geometries most commonly used.
