Roger is presently Vice-Chairman for the Chicago Section of the IEEE EMC Society.

Tim Lusha

TimTim Lusha, Senior EMC Engineer, has been with D.L.S. for the past 21 years. He has four iNARTE certifications: EMC Engineer, EMC Laboratory Engineer, EMC and ESD Technician. He is a current member of RTCA/DO-160, IEEE and ESDA. Tim has worked at D.L.S.’s Wisconsin facility involved in FCC, EC and VCCI commercial requirements as well as measurement uncertainty, transmitters and calibrations. He is presently at our Wheeling location immersed in MIL STD 461 and DO-160 topics, custom test setups, software programs and networks for lightning and related testing. Tim is a graduate of the Milwaukee School of Engineering (MSOE) Milwaukee, WI in addition to graduate coursework in engineering and other courses in mechanical design.

Jack Prawica

Jack PJack Prawica, Senior EMC Engineer, iNARTE Accredited Test Laboratory Engineer, is technical manager of D.L.S. Electronic Systems, Inc. He is a graduate of DeVry University of Electrical and Electronic Engineering, Chicago as well as Keller Graduate School of Management of Business Administration. He worked for Hewlett-Packard prior to joining D.L.S. Electronic Systems, Inc. Jack has over 25 years experience in the EMC field. Most of his time has been devoted to testing and consulting in electromagnetic engineering focusing on Military, Avionics, Medical, Commercial and other related market segments. He specializes in EMI, EMC, RFI, & Lightning consulting and testing. He is a member of the IEEE EMC society, SAE AE-2 lightning committee and AE-4 Civil Aircraft EMC working group.

Jack Black

Jack BJack Black is a key person in the sales and marketing group at D.L.S. Electronic Systems, Inc. and has over 28 years experience in the field of EMC with concentration in shielding, materials and component shielding on the PC board. He has published several technical papers and articles in these fields, as well as product safety compliance. Jack is also active with the IEEE EMC Society Chicago chapter and serves as Chapter Chairman. Please feel free to ask Jack about EMC, Safety, Environmental, EMC shielding issues, and about new North American compliance programs (including safety) now available.

Corey Sweeney

CoreyCorey Sweeney has been with D.L.S. since it was founded in 1983. He has helped with testing, developed automated test software, contributed to TC 9 EMC Modeling, and today is part of D.L.S.’s management team, including heading the IT department. He did both graduate and undergraduate work at DePaul University in Chicago.

Corey developed two sections of our seminar: First, where we manually calculate the emissions from a circuit board, and secondly, where we place the circuit board in an enclosure and calculate the shielding the box provides. Combining the shielding with the emissions from the circuit board gives an overall system emissions. These calculations give a better understanding of the various equations used in the seminar textbook which we have now automated with our exclusive software.
