ECpE Department receives major external research awards

Posted on | Kristin Clague

During the months of July through September 2016, Iowa State University’s Department of Electrical and Computer Engineering received many external research awards from the Department of Energy (DOE), the National Science Foundation (NSF) and other groups.

Coover in the FallMajor grants from the DOE include an award of $1,162,477 for a project entitled “Autonomous Tools for Attack Surface Reduction,” with Manimaran Govindarasu as Principal Investigator (PI) and Venkataramana Ajjarap and Doug Jacobson as Co-Principal Investigators (Co-PI). The total anticipated amount of the award is $2,981,103. The DOE also awarded $1,318,903 for a project called “Novel Light Extraction and Utilization, Organic LED (OLED) Core Technology Research: Enhanced Light Extraction from Low Cost White OLEDs (WOLEDs) Fabricated on Novel Patterned Substrates,” with Ruth Shinar as PI and Rana Biswas and Joseph Shinar as Co-PIs.

A variety of projects received grants from the NSF, with one highlight being $4,054,476 for the project “WI-ECSEL Scholarship Program (Women in Electrical, Computer, and Software Engineering as Leaders,” with Joseph Zambreno as PI and Doug Jacobson, Phillip Harrison Jones, Lisa Larson, Mani Mina, Sarah Rajala, Sarah Rodriguez, Diane Rover and Mack Shelley as Co-PIs.

VEISHEA project could be first answering machine

ECpE alum, James Mitchell (EE ‘82), may have created the world’s first digital outgoing telephone message machine during his time at Iowa State University.

Mitchell displayed a working prototype of the digital outgoing message with a taped incoming system at the Iowa State University VEISHEA Engineering Open House in April 1982. Using 35 integrated circuits (16 memory chips) and the digital and analog experience from his courses, Mitchell created his project in just three weeks.

“I saw the open house as an opportunity,” Mitchell said. “I wanted to do something as profound as I could possibly do.”  He added that he had to develop his own a Analog to Digital converter and encoding process, as these were not readily available commodities during that time.

The project won a Gold award, the highest of the three levels, from David T. Stephenson faculty advisor and J.O. Kopplin the department chair of the time.

In Mitchell’s award letter, Stephenson and Kopplin state that his phone-answering system was “a particularly interesting exhibit for the many visitors who have some knowledge of digital techniques and who have ever found themselves ‘talking to a machine.’”

Mitchell credits the VEISHEA Open House with helping him receive his position at Rockwell Collins after graduation. He was offered the job after his VEISHEA demonstration and continued to stay with Rockwell Collins for the next 33 years until retiring last December.

Although Kazou Hashimoto holds the patent for a digital answering machine, he did not invent the machine until 1983, a year after Mitchell’s presentation of his digital answering machine.

Mitchell may also hold the title for the first created LED television display in 1977. His monochromatic model was displayed at the International Science and Engineering Fair (ISEF) expo in Anaheim Ca. 1978 and won awards from NASA, General Motors Corporation and Westinghouse.

Currently, Mitchell holds 40 patents with another 12 pending, the majority related to aircraft and satellite communication. He lives in Cedar Rapids with his wife.
