A BIT OF FUN FIRST…

The Grade and the Gator

• Two doors containing either Gators or Grades!

(Normally of course, Hurricanes eat Gators for Breakfast…)

But let’spretend they’rescary…

The Grade and the Gator

• You will be shown two doors, to two rooms.– Each could contain either an “A” or a gator…– It could be that both rooms contain an “A”, or that both

rooms contain a gator!• You will need to reason carefully and logically to survive!• Each question, pick a door, Orange or Green, or decide not to

open a door.– You score one point for picking an “A”, or for refusing to pick if both

doors contain gators.– Three points available for your participation grade today– If you answer wrong, you may write a short paper describing what you

did wrong, and how to find the right answer, due next class.

The Grade and the Gator

• Form up into groups of four• On a sheet of paper, list the first and last

names of each student in the group, and pick a team name– Discuss your answers, and record them– Each group will then give their answers to the

class

The Grade and the GatorQ1

One of these is true…

In this room, there is an “A”, and in the other room there is

a gator.

The other is false…

In one of these rooms there is an “A”, and in one of these

rooms there is a gator.

The Grade and the GatorQ1

One of these is true… The other is false…

A

The Grade and the GatorQ2

Either both signs are false…

At least one of these rooms contains an “A”

Or both are true…

A gator is in the other room…

The Grade and the GatorQ2

Either both signs are false… Or both are true…

A

The Grade and the GatorQ3

Either both signs are false…

Either a gator is in this room, or an “A” is in the other room.

Or both are true…

An “A” is in the other room.

The Grade and the GatorQ3

Either both signs are false… Or both are true…

What does this have to do with ECE?

WHAT IS ECE?

ECE

Electrical Engineering• (Audio Engineering)• The study and design of

electrical signals and electrical systems– Distribute, convert energy

between various forms.– Gather, store, process,

communicate, present, and display data or information

Computer Engineering• (Software Engineering)• The process of analyzing,

designing, and integrating the hardware and software systems needed for information processing or computation.– Computer Software

Engineering– Computer Hardware

Engineering

Not as different as they seem

Examples of things made possible by ECE• DVD Players

• And the DVD standard

• Cellular phones• Cellular networks and standards

• Electric motors• And Electro magnets

• Power Systems• Communication Systems• Global positioning system• And more

Key industries that employ electrical and computer engineers

• Aerospace• Bioengineering• Environmental engineering• Manufacturing• Semiconductors• Telecommunications• Education and Research• Energy and electric power• Transportation and automotive• Film, games, and entertainment• …

Factory automation

Instrumentation(Soleil Synchrotron)

Building Systems

Example: Medical Devices

•Emerging direction: Cell phone based medical devices for affordable healthcare•e.g. “Telemicroscopy” project at Berkeley

•e.g. Cell-phone based blood testing device developed at UCLA

CPS Example – Printing Press

• High-speed, high precision• Speed: 1 inch/ms• Precision: 0.01 inch

-> Time accuracy: 10us

• Open standards (Ethernet)• Synchronous, Time-Triggered• IEEE 1588 time-sync protocol

• Application aspects• local (control)• distributed (coordination)• global (modes)Bosch-Rexroth

Example: Toyota autonomous vehicle technology roadmap, c. 2007

It is important to stay current!

• The future is hard to predict, and the world is changing quickly!

Three generations• My mother

– No running water until she was 8– Phone was a party line, 6 families shared it– Answering machine when she was 38

• Me– Computer in the house when I was born– First access to the internet when I was 13– First cell phone when I was 21 (analog)

• You?

The future is hard to predict

• “Heavier-than-air machines are impossible”– Lord Kelvin, President of the British Royal Society,

1895• “I think there is a world market for maybe five

computers”– Thomas Watson, IBM Chairman, 1943

• “640K ought to be enough for anybody”– Bill Gates, Microsoft Chairman, 1981

Within the span of a single human life, we went from one of the world’s most respected scientists doubting heavier-than-air flight was possible… to landing on the moon.

And the pace is accelerating…Moore’s Law

The complexity for minimum component costs has increased at a rate of roughly a factor of two per year... Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years. That means by 1975, the number of components per integrated circuit for minimum cost will be 65,000. I believe that such a large circuit can be built on a single wafer.- Gorden E. Moore

The internet of things

• The State of the Digital Universe

A scary and exciting thought…

• The systems you will be working on when you graduate do not even exist today
