The event\u0026nbsp;showcased the research projects of the 20 undergraduate student teams for the 2014 academic year. The ORS Program is an academic enrichment program in the School of Electrical and Computer Engineering that promotes student retention and academic performance through an extended undergraduate research experience.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThe event was hosted by Jill Auerbach, director of ORS and the Office of Undergraduate Research in ECE, and Steven McLaughlin, Steve W.

This year, first place went to the team consisting of Damilola Apatira, Kevin Berman, Shad Hepner, and Olivia Wasdin.\u0026nbsp; The team was mentored by Ph.D. student Blake Marshall and advised by Dr. Greg Durgin.

Low-power microcontrollers are used with RF-to-DC energy harvesters for sensing applications and backscatter communications, but the microcontroller\u0027s impedance can vary, which results in reduced efficiency of energy harvesting circuitry. This research proposes a 5.8 GHz energy harvesting circuit that matches itself to a variable load by implementing a single control line from the microcontroller to an RF switch to increase energy conversion efficiency.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EImproving the Signal Integrity in High Speed Circuits\u003C\/strong\u003E\u003Cbr \/\u003EA major flaw with the power plane design of printed circuit boards (PCBs) is that there are return path discontinuities (RPDs).\u0026nbsp; These discontinuities result in loss of signal integrity within the PCB.\u0026nbsp; This project\u0027s main goal is to improve the signal integrity of a PCB through investigation of various power transmission line board designs and the components used.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EOn April 16, the Opportunity Research Scholar\u2019s (ORS) Program held its 12\u003Csup\u003Eth\u003C\/sup\u003E\u0026nbsp;annual Undergraduate Research Awards Program.
