With more cars becoming hybrid electric and total electric powered, the demand for Electrical and Computer engineers will increase in the auto industry. The Volt by GM will be an all electric car. Other manufacturers are also introducing all electric cars

This was a good idea but was scrapped because the solar powered lights would not provide enough illumination. It will be revisited as solar cells and LEDS become more efficient and brighter

Opto-electronics (devices that use light) include LEDs or light emitting diodes, solar cells, and fiber optic components

Antennas How Wireless Works by Preston Gralla

Early Mobile Phones where not cellular but used a common centrally located tall antenna (similar to police and fire radios) and were limited in the number of phone numbers available

From Engr 1201 we will use:

Engr 1202 EE project and the clean room 1. To work in the clean room, students must wear clean room garments 2. To work in the clean room, students must pass the required safety test 3. Students need to be aware of the hazards in the clean room at all times

Clean Room?

Cameron Hall On Craver Road, across from parking lot 16 Microelectronics Clean Room on second floor, room 201

Required gowning when working in the ECE Microelectronics Clean Room Special material garments Special material garments Hood Hood Coveralls Coveralls Boots Boots Face mask Face mask Goggles when working with chemicals Goggles when working with chemicals Gloves Gloves

Students Working in the ECE Microelectronics Clean Room

Requirements to work in the ECE Microelectronics Clean Room Gown in clean room garments at all times Gown in clean room garments at all times Understand clean room protocols and procedures Understand clean room protocols and procedures Understand the hazards and dangers when working in the clean room Understand the hazards and dangers when working in the clean room Take and pass a clean room safety test Take and pass a clean room safety test

Units used in electrical and computer engineering Units Tera Giga – Mega – Kilo – Milli – Micro – Nano – Pico –

Understanding the SI system is essential in engineering Power – kilovolts, megawatts Circuits – microamps, picofarads, millivolts Communications – megahertz, gigahertz Computer speed – nanoseconds Time dependence – microseconds, milliseconds

How much does it cost to run a 100 watt light bulb Typical cost from Duke Power is $.08/Kw-Hr Convert 100w to Kw (Kw = 10 3 W) 100W=.1 KW For 1 hour a 100w light bulb uses.1 KW-Hr For 24 hours, a 100W light bulb uses (24 hr) x (.1 KW- hr) = 2.4 Kw-Hr/day Cost for 24 hr is ($.08/Kw-hr) x (2.4 Kw-hr/day) =$.192/day Cost for a month is (30 days) x ($.192/day) = $5.76/month Cost for a year is (365 days) x ($.192/day) = $70.08/year

Compare cost to a high efficiency replacement lamp If an equivalent high efficiency lamp uses 13 watts instead of 100 watts 13 watts =.013 Kw (.013 KW-Hr) x (24Hr/day) =.312 KW-Hr/day ( $.08/Kw-Hr) x (.312 KW-Hr/day) = $.02496/day ($.02496/day) x (365 days/yr) = $9.11/yr 100watt light bulb = $70.08/yr 13 watt light bulb = $9.11/yr Based on lamp running 24 hours per day, everyday for a year

This analysis can be used for any electrical device Every electrical device will show power required to operate it Typical computer may use 120V, 1.5A (120V)(1.5) = 180 watts =.180 Kw (.180 Kw-hr) x ($.08/Kw-Hr) = $.0144/Hr ($.0144/hr) x (24 hr/day) = $.3456/day ($.3456/day) x (365 days/yr) = $ /yr There will be a questions on this type analysis on the tests
