Instrumentation And Control Engineering Quotes

Which Brian had done. They had taken off and that was the last of the conversation. There had been the initial excitement, of course. He had never flown in a single-engine plane before and to be sitting in the copilot’s seat with all the controls right there in front of him, all the instruments in his face as the plane clawed for altitude, jerking and sliding on the wind currents as the pilot took off, had been interesting and exciting. But in five minutes they had leveled off at six thousand feet and headed northwest and from then on the pilot had been silent, staring out the front, and the drone of the engine had been all that was left. The drone and the sea of green trees that lay before the plane’s nose and flowed to the horizon, spread with lakes, swamps, and wandering streams and rivers.

A convivial society should be designed to allow all its members the most autonomous action by means of tools least controlled by others. People feel joy, as opposed to mere pleasure, to the extent that their activities are creative; while the growth of tools beyond a certain point increases regimentation, dependence, exploitation, and impotence. I use the term "tool" broadly enough to include not only simple hardware such as drills, pots, syringes, brooms, building elements, or motors, and not just large machines like cars or power stations; I also include among tools productive institutions such as factories that produce tangible commodities like corn flakes or electric current, and productive systems for intangible commodities such as those which produce "education," "health," "knowledge," or "decisions." I use this term because it allows me to subsume into one category all rationally designed devices, be they artifacts or rules, codes or operators, and to distinguish all these planned and engineered instrumentalities from other things such as basic food or implements, which in a given culture are not deemed to be subject to rationalization. School curricula or marriage laws are no less purposely shaped social devices than road networks. 5

Great designers produce pleasurable experiences. Experience: note the word. Engineers tend not to like it; it is too subjective. But when I ask them about their favorite automobile or test equipment, they will smile delightedly as they discuss the fit and finish, the sensation of power during acceleration, their ease of control while shifting or steering, or the wonderful feel of the knobs and switches on the instrument. Those are experiences

The boys reached the flight line just as Randy was completing a preflight check of the aircraft. In a few minutes they were strapped in their seats and taxiing toward the active runway. The pilot remarked, “Because of the direction of the wind, that runway is the only one I can use to head the plane into the wind.” He tuned his radio to the proper frequency and contacted Bayport tower. An immediate reply crackled from the plane’s receiver. “Ace Service Flight Two-Six is cleared to runway One-Niner. Wind’s from the southeast at fifteen knots. Altimeter setting, Two-Niner-Eight-Six.” Randy paused to check his instruments, controls, and engine magnetos. The tower then cleared him for immediate take-off. Turning into the runway, he eased the throttle ahead. Soon he and his passengers were airborne and taking a course to the northwest. The boys gazed down at the earth below. The terrain became more hilly with each passing mile. The expanses of wooded areas looked like rumpled deep-green carpet. Here and there, lakes and small streams reflected the sun in bright

FUNCTIONAL SAFETY AS PER IEC 61511 SIF SIS SIL TRAINING FUNCTIONAL SAFETY COURSE OBJECTIVES: The main objective of this training program is to give engineers involved in safety instrumented systems the opportunity to learn about functional safety, current applicable safety standards (IEC 61511) and their requirements. The Participants will be able to learn to follow: • Understand the basic requirements of the functional safety standards (IEC 61511) • The meaning of SIS, SIF, SIL and other functional safety terminology • Differentiate between safety functions and control functions • The role of Hazard and Risk analysis in setting SIL targets• • Create basic designs of safety instrumented systems considering architectural constraints • Different type of failures and best practices for minimizing them • Understand the effect of redundancy, diagnostics, proof test intervals, hardware fault tolerance on the SIL • The responsibility of operation and maintenance to ensure a SIF meets its SIL • How to proof test a SIF The Benefits for the Participants: At the conclusion of the training, the participants will be able to: Participate effectively in SIL determination with Risk graph, Risk matrix, and LOPA methodology Determine whether the design of a Safety Instrumented Function meets the required SIL. Select a SIF architecture that both meets the required SIL and minimizes spurious trips. Select SIF components to meet the target SIL for that SIF Target Audience: Instrument and Control Design and maintenance engineers Process Engineers Process Plant Operation Engineers Functional safety Management Engineers For Registration Email Us On techsupport@marcepinc.com or call us on 022-30210100

smiled, and Melody knew she was impressed. Val pointed at a small window that looked down on the room. “What’s that?” she asked. “Who’s up there?” “That’s the control room,” he said. “Those are the sound engineers, and they hear everything.” Dwayne got up and crossed the room, motioning Melody to follow. “See these X’s back here on the floor? This is where you’ll stand. This microphone will be yours. Phil and Artie will be over here. I’ll be at the piano.” “How come Melody’s so far from the piano?” Lila asked suspiciously. Dwayne smiled. “Those folks who work up in that control room know their business. Trust me, you’ll hear Dee-Dee. And us and the instruments, too. It’s what they call mixing the sound.” Just then, Artie and Phil came into the studio. Phil stopped and said hello to Lila. Then he turned to Dwayne. “I know we only planned for lil sis to do backup, but how about if the others hang out with us and dance? That will give us a great vibe.” Sharon’s and Val’s eyes grew wide. Lila smiled.

If we want to change course, it’s as simple as ABC. We just get Roger Chaffee’s tracking network to send up a state vector and a couple of other things to Dave Scott’s computer, which feeds pointing commands through Dick Gordon’s instrument panel to Donn Eisele’s controls, which cause Walt Cunningham’s electricity to power Gene Cernan’s engines, which fire, to get us out of Bill Anders’s radiation zone into the position called for by Buzz Aldrin’s flight plan. The rest of you guys must be loafing!

Theoretical and experimental physicists, working on problems of esoteric intellectual interest, provided the knowledge that eventually was pulled together to make the H-bomb, while mathematicians, geophysicists, and metallurgists, wittingly or unwittingly, made the discoveries necessary to construct intercontinental ballistic missiles. Physicists doing basic work in optics and infrared spectroscopy may have been shocked to find that their research would help government and corporate engineers build detection and surveillance devices for use in Indochina. The basic research of molecular biologists, biochemists, cellular biologists, neuropsychologists, and physicians was necessary for CBW (chemical-biological warfare) agents, herbicides, and gaseous crowd-control devices… Anthropologists studying social systems of mountain tribes in Indochina were surprised when the CIA collected their information for use in counterinsurgency operations. Psychologists explored the parameters of human intelligence-testing instruments which, once developed, passed out of their hands and now help the draft boards conscript men for Vietnam and the U.S. Army allocate manpower more effectively. Further, these same intelligence-testing instruments are now an integral part of the public school tracking systems that, beginning at an early age, reduce opportunities of working-class children for higher education and social mobility

The boundary between dreams and reality gets muddy indeed when we consider the nature of our perceptions. Our senses, those windows to the world, are far from perfect instruments that are extremely susceptible to manipulation and misinterpretation. What we perceive as unquestionably solid and real could be nothing more than smoke and mirrors, projections of our own psyches.
