About the Dynamic Measurement Group
The focus of this organization is centered around vibration, acoustic, pressure, force, torque, data acquisition and other related areas dealing with dynamic sensors. This is a new group being formed in Northern Ohio to provide the opportunity for you the user of this technology to have a place to meet, discuss common interests, network with others and to attend technical presentations. There is no membership fee and we have tried to keep the meeting cost and meals as modest as possible. Please help us by canceling your reservation before the day of the meeting if for some reason you can not attend so we are not stuck paying for extra meals.

Future meeting announcements will be sent by e-mail only, so if you did not receive this via e-mail and would like to be notified for future meeting please visit our web site at www.dynamicmeasurementgroup.org.

September 03, 2009	Topic: Impulse Noise Measurements Speaker: Gregory A. Flemme, Ph.D. Wesstern Michigan University Details: Short Bio Greg Flamme is an Associate Professor in the Department of Speech Pathology and Audiology at Western Michigan University. He earned a Ph.D. in Audiology from the University of Memphis and conducted postdoctoral work at The University of Iowa in the Department of Speech Pathology and Audiology and in the College of Public Health. His current research interests include the examination of hearing impairment as a public health problem in rural areas, including work with civilian exposures to impulse noise, including noise from firearms and fireworks. Description of Session Impulse noises are brief sounds with a nearly instantaneous rise and rapid decay. Impulses produced by chemical combustion, such as those from gunshots, fireworks, and vehicle airbags are so brief that the sensation of loudness evoked by the impulse doesn’t correspond to the intensity of the sound or to the listener’s risk of noise-induced hearing loss. Impulse measurements are complicated because one needs to account for the characteristics of the shock wave, the response of the transducer, and the capacity of the preamplifer and analog-to-digital converter to follow the pressure wave. This presentation will address the acoustic parameters of impulses, the impact of different recording techniques, and the association between the acoustic characteristics of impulses and the risk to human hearing.
May 06, 2009	Topic: Convergence of the Dynamic Signal Analyzer and Vibration Data Collector Speaker: James Zhuge, Ph.D. Crystal Instruments Details: Convergence of the Dynamic Signal Analyzer and Vibration Data Collector This presentation discusses the evolution of the Dynamic Signal Analyzer (DSA) and Vibration Data Collector (VDC) in the past 4 decades. Both DSA and VDC instruments are derived from the FFT analyzers that were first introduced in the 1970s. Traditionally, a DSA includes some combination of the following functions; transient time capture, power spectrum, FRF, order tracking, octave analysis, production limit testing, swept sine, signal source and a few others. The DSA is used for testing and measurement purposes. Users are mainly engineers, researchers, or consultants who want to improve the quality of their structure design. The VDC product targets machine maintenance applications. VDC users typically fall into two distinct groups. The first group includes the experts who typically define the parameters and routes. Later this group will do trending or signature analysis. The second group is the people who actually conduct the data collection. People in the first group often have the need for the functions that are only available in a DSA instrument. The traditional DSA products are not well suited for the VDC application; mainly because these products are too big, consume too much power, are not portable and are less rugged than a VDC product. Conversely, the traditional VDC products cannot perform well in the DSA market due to their limited number of channels and lower precision and accuracy. The previous solution to this conflicting need has been to purchase multiple instruments, resulting in much higher cost to the organization. In recent years, with the advances of technology, it is now possible to integrate the DSA and VDC products into one product platform, which can have profound impact to this industry. About the Speaker, James Zhuge, Ph.D. James Zhuge is the President of Crystal Instruments (www.go-ci.com ), a California based provider of data acquisition and dynamic signal analysis products.

September 04, 2008	Topic: Dynamic Measurements and Trip to Mars Optimizing Astronaut Exercise in a Long-Term Space Mission Speaker: Sergey Samorezov Exercise Countermeasures Laboratory Details: Long-term exposure to weightlessness negatively affects astronaut’s health and ability to perform critical mission tasks. Exercise in space is one of the possible countermeasures. NASA Glenn Research Center, in partnership with Cleveland Clinic, built a Zero gravity Locomotion Simulator (ZLS) for ground-based simulation of exercise in space. Human subjects exercise on the ZLS to test the effectiveness of exercise hardware and to determine optimum exercise prescriptions. The goal of the presentation is to provide an overview of ZLS experimental activities and how the uses of corresponding dynamic measurements are made. Speaker Bio: The presenter, Mr. Sergey Samorezov, is a mechanical engineer with experience in industrial vibration monitoring, structural vibration testing, equipment troubleshooting and inventive problem solving. He started his engineering career in the former Soviet Union, in shipbuilding, helping to reduce ship radiated noise, after President Reagan announced that the Soviet ships were very noisy. Years later he worked on the ballistic tests for the Space Shuttle Columbia accident investigation. Now he is supporting US Space Program by conducting dynamic measurements at the NASA GRC Exercise Countermeasures Laboratory. Mr. Samorezov is Level IV Certified Vibration Specialist and a member of the Vibration Institute.

March 05, 2008	Topic: A Discussion Panel The Art and Science of Thermography Speaker: Al Feldman, Fluke Corporation Lenny Shaver and Joe Sharp, LumaSense Technologies Details: Thermal imagers are instruments that create pictures of heat rather than light. Infrared (IR) energy is measured pixel-by-pixel and the data converted to corresponding images, assigning color based on temperature. Identification and mitigation of thermal loading, whether in an R&D or manufacturing environment, improves equipment reliability and results in improved equipment reliability. We will discuss the fundamentals of thermal imaging, applications, benefits and the variables that can effect measurement uncertainty.
