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.

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

The Engr 1202 ECE Project Research, design, and fabricate a miniature planar antenna for use in: 1) Mobile phone using the PCS frequency of MHz 2) “Bluetooth” and Wi-Fi antenna using the frequency band of MHz 3) RFID antenna using the frequency band of MHz 4) GPS antenna using the frequencies of MHz and MHz Maximum size of 20mm x 20mm, minimum size of 5mm x 5mm. Width on antenna not less than 1mm. Design to have no sharp corners. Reliability, cost, and manufacturability to also be considered

The Engr 1202 ECE Project Teams will be formed of 4 to 6 members. Each team will decide on various options to design and fabricate a prototype. The antenna will be fabricated in the Cameron clean room using a silicon wafer as a base. The design will be evaluated on cost, reliability, and manufacturability. Each team will make a verbal presentation of their design and a final report Teams will be formed of 4 to 6 members. Each team will decide on various options to design and fabricate a prototype.

From Engr 1201 we will use:

Engr 1202 ECE and the clean room 1. A student must take and pass Engr 1202 ECE to get a degree in electrical or computer engineering 2. To pass Engr 1202 ECE, students must work in the clean room 3. To work in the clean room, students must wear clean room garments 4. To work in the clean room, students must pass the required safety test

How much does it cost to run a 100watt light bulb Typical cost from Duke Power is $.08/Kw-Hr Typical cost from Duke Power is $.08/Kw-Hr Convert 100w to Kw (Kw = 10 3 W) Convert 100w to Kw (Kw = 10 3 W) 100W=.1 KW 100W=.1 KW For 1 hour a 100w light bulb uses.1 KW-Hr For 1 hour a 100w light bulb uses.1 KW-Hr For 24 hours, a 100W light bulb uses (24 hr) x (.1 KW- hr) = 2.4 Kw-Hr/day For 24 hours, a 100W light bulb uses (24 hr) x (.1 KW- hr) = 2.4 Kw-Hr/day Cost for 24 hr is ($.08/Kw-hr) x (2.4 Kw-hr/day) =$.192/day Cost for 24 hr is ($.08/Kw-hr) x (2.4 Kw-hr/day) =$.192/day Cost for a month is (30 days) x ($.192/day) = $5.76/month Cost for a month is (30 days) x ($.192/day) = $5.76/month Cost for a year is (365 days) x ($.192/day) = $70.08/year Cost for a year is (365 days) x ($.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 If an equivalent high efficiency lamp uses 13 watts instead of 100 watts 13 watts =.013 Kw 13 watts =.013 Kw (.013 KW-Hr) x (24Hr/day) =.312 KW-Hr/day (.013 KW-Hr) x (24Hr/day) =.312 KW-Hr/day ( $.08/Kw-Hr) x (.312 KW-Hr/day) = $.02496/day ( $.08/Kw-Hr) x (.312 KW-Hr/day) = $.02496/day ($.02496/day) x (365 days/yr) = $9.11/yr ($.02496/day) x (365 days/yr) = $9.11/yr 100watt light bulb = $70.08/yr 100watt light bulb = $70.08/yr 13 watt light bulb = $9.11/yr 13 watt light bulb = $9.11/yr Based on lamp running 24 hours per day, everyday for a year Based on lamp running 24 hours per day, everyday for a year
