The theme was "New Millennium-New Vision for Ultrasonics"-- the event, the 30th annual UIA Symposium. Over 100 people attended the 30th annual UIA symposium at the Hyatt on Capitol Square in Columbus, Ohio on June 11-14, 2000. Attendees agree that the event was packed from morning until night with presentations, technical courses, exhibits, networking opportunities, and much more.

Speakers representing six countries from industry and academia presented the latest in ultrasonics. More than twenty technical papers were presented in four areas: Industry Applications, Sonically Enhanced Processing, Material Fabrication and Joining, and Biology/Medical.

Dr. Karl Graff, Executive Director of EWI, opened the symposium with a presentation on "Power Ultrasonics 2000: Glancing Back, Looking Ahead." In glancing back, Dr. Graff provided a historical overview and noted the current status of the industry. In looking ahead, he takes advantage of the unique opportunity of a new century, which is everyone's favorite time to predict the future, and attempts some prognosticating in power ultrasonics. His research included a detailed survey that enlisted some of the leading companies and experts in the ultrasonics field.

Renowned speakers from around the world included Dr. Kenneth Suslick, University of Illinois, who kicked off the Sonically Enhanced Processing session; Oleg Abramov, TechSonic GmbH; Don Feke, Case Western Reserve University, Oleksandr Kozlov, National Academy of Sciences of the Ukraine, and Juan Gallego-Juarez, Institute de Acustica Calle Serrano all of whom presented in the Industrial Applications session. Dr. Lawrence Crum, University of Washington led the Biology/Medical session and Jiromaru Tsujino, Kanagawa University, Japan who was featured in the Material Fabrication and Joining session.

Three technical courses were featured during the conference. Emery Rose of E.S.R. presented, "Synthesis of a Discrete Time Adaptive Phase Lock Loop." Dave Grewell of Branson Ultrasonics captivated his audience with, "Amplitude and Force Profiling in Ultrasonic Welding of Thermoplastics." Computer Aided Engineering Associates', Pat Cunningham, presented "Use of Finite Element Methods for Utlrasonic Applications."

Jennifer Schramm of Purdue University was the recipient of the annual Procter & Gamble Graduate Research Award. Michael McDonald of P&G presented Jennifer with a plaque and a $1,500 scholarship. Jennifer studied at Purdue under the direction of Dr. Inez Hua, Assistant Professor, also a speaker at the symposium. Jennifer presented her work on "Ultrasonic Decomposition of the Pesticides Dichlorvos and Alachlor: Identification of By-Products and Reaction Kinetics" at the member's annual meeting. As an added bonus, Jennifer's parents were in attendance to see her receive her award as well as present her research.

Association business was conducted at the member's annual meeting where officers Mark Schafer, Kevin Klein, Ron Manna, and Alan Broadwin were reelected to serve another term. Two new directors were elected to the Board: Paul Stokes of Staveley Sensors and Tom Kirkland of Dukane Ultrasonics.

Attendees also enjoyed the opportunity to network with fourteen exhibitors, many of which demonstrated the latest in ultrasonic equipment.

Sam Berliner continued the UIA Profile Series on the pioneers of utlrasonics featuring Robert S. Soloff, innovator and entrepreneur, from Sonics & Materials, Inc. Mr. Soloff was instrumental in the development of ultrasonic welding of plastics as it is practiced today and in several other related technologies. The Profile Series has featured the following in prior years: Janet Devine, Sonobond; Howard Alliger, Heat Systems (now Misonix); Charles Kelman, Phaeco-Emulsifier; Norm Branson, Branson Ultrasonics; Tom Baldridge, Lewis; and three of the greats, Peter Bloch, Bob Fehr and Stan Jacke.

Company sponsors included Sonobond, Branson, Dukane, Misonix, Etrema, Staveley Sensors, EWI, and Zevex.

Mr. Chuck O'Connor, Vice President of the Center for Science and Industry (COSI) in Columbus, posed a challenge to each attendee. As the keynote dinner speaker, Mr. O'Connor took each participant back to the days when they were young asking them to remember who inspired or influenced their decision towards a career in science and technology. He challenged everyone to find a way either through volunteering or mentoring to influence the scientists of tomorrow and inspire them towards a career in technology.

The final day of the symposium, featured a tour of Edison Welding Institute (EWI). Technology demonstrations included ultrasonic levitation, vibration amplitude measurement, ultrasonic atomization, plastic welding, ultrasonic impedance measurement, film bonding, and ultrasonic metal welding.
