Dinner Presentation

CE, The Mark of Europe

James Blaha, Senior Vice President of L.S. Compliance, Inc.

All electronic and electrical equipment manufactured for the European Union must comply with the EMC Directive and display the “Mark of Europe”.

What is this mark that consists of the letters CE?

What does it stand for and why do products that are not electrical also require the CE mark? Look at the products you use every day and ask why are they marked?

This presentation will provide you with a complete understanding of the European Union’s requirements for CE marking.

A review of how international organizations like the IEC and ISO have contributed to the European Union’s harmonized approach to standardization will also be discussed.

James Blaha is a senior vice-president for L. S. Compliance, Inc., an internationally accredited EMC Testing Laboratory. He is a graduate of Milwaukee School of Engineering, holding an Associate Degree in Electronic Communications Engineering Technology, a Bachelor's Degree in Biomedical Engineering and a Master's Degree in Engineering Management. Blaha's industrial experience includes a 22-year career with Hewlett-Packard Co. As a member of HP's Medical Products Group, Blaha's product responsibilities in field marketing include critical care networks; cardiology; obstetrical; resuscitation and anesthesia delivery systems. As a member of the sales panel for product development, Blaha made contributions to the development of critical care and anesthesia delivery products. District management and field sales management were also a part of his HP career. Responsibilities at L. S. Compliance, Inc. include Quality Management and EMC laboratory conformance to Mutual Recognition Agreements between the US and the world markets. Blaha serves as Adjunct Associate Professor in MSOE's - MS in Engineering Management program. He is also an IEEE society member for electromagnetic compatibility.

Magnetics Chapter

Modeling electromechanical systems with eddy currents using SPICE and finite elements

John R. Brauer, MSOE & Ansoft Corp.

Electromechanical systems are modeled using SPICE for their electric circuits and, by analogy, for their mechanical components. Magnetic components such as solenoid actuators and motors are modeled in SPICE based upon the results of parametric electromagnetic finite element software. Recent work to be report here allows inclusion of eddy current effects in the SPICE model. An example will accurately predict the delay in electromechanical response time due to the eddy currents.

Dr. John R. Brauer is Director, Electrical and Computer Programs, Applied Technology Center, Milwaukee School of Engineering. He is a Fellow of the IEEE and Chairs the Milwaukee Chapter of the IEEE Magnetics Society. He is also a board member of the InternationalCompumag Society and past Vice-President of the Applied Computational Electro-magnetics Society. He has published over 130 technical papers and received the IEEE Section Memorial Award in 1988. His consulting clients include Ansoft Corporation and others.

True Ambient Cancellation for EMC Emissions Testing

RF Emissions' testing is complicated by the presence of strong ambient EMI sources. A noisy RF environment makes identification of the EUT's signal difficult, if not impossible, and is time consuming. The use of a semi-anechoic chamber is not always a financial or practical option. Tonight's presentation will discuss the ambient noise environment we work in along with a product demonstration of a "VIRTUAL CHAMBER". This demonstration will focus on the ability to produce Ambient Cancellation of the RF environment we work in. This presentation will also focus in on sources of EMI noise, localization of RF sources and the separation of EUT and ambient noise signals.

Speaker and Presenter:
Mr. Kevin Baldwin
Sales Manager / Sr. Applications Engineer
ETS - EMC Test Systems of Austin, Texas
