MADE Meeting Minutes February 24, 1998 Phoenix, AZ Attendance Paul Russell - Hewlett-Packard Carles Vinas - Hewlett-Packard Bill Kipp - Lansmont Dick Sheehan - 3M Derek Haines - Compaq Jorge Marcondes - SJSU Denny Stover - Dow Plastics Ron Johnson - Intel Julian Kim - Sony Kevin Howard - Hewlett-Packard Greg Hoshal - IST Overview Paul Russell and Jorge Marcondes gave the group a general overview of the MADE progress since the last meeting held at TransPack '97. Data Results of Alpha Phase - Six round trips were recorded by both units; 2 files were lost. - Looked at drops above 10 inches (equivalent drop height). - Examined same time stamped events - There was disagreement between units - Alpha Phase - First blush was that we have a problem. Side by side recorders were showing a wide variance in recorded events. Recorder manufacturer became involved to analyze files and came back with more differences. - Issue was that the manufacturer were looking at different parts of an event in what was termed an "Event Storm." This occured because the "window" recorded did not agree completely between units (although the units were triggered by the same event, the recorded wave forms started and ended at different times, sometimes missing important parts of an event). - Conclusion - Waveform good agreement between units. - Recorders software analysis did not agree. - System analysis tools are different so events didn't map together - Real events - almost no free fall events happened, only impacts - no flat line in distribution, always activity - Lansmont - Based on the findings, Lansmont is moving forward with an independent research study to understand how time / acceleration can translate in to usable lab testing. - To keep MADE on track and speed up progress, Lansmont offered 12 Saver units to be used in the Beta phase. These units can be used until the end of the year at no cost. Lansmont will also provide funds for the analysis of the collected data. - The group accepted the generous offer. IST EDR 3 units will still be used in Beta, as they become available, and IST offered to analyze those files. Finalize Alpha - The group concluded that Alpha phase still needs to be concluded on characterizing the differences seen by both recorder units. ISTA - Interested in partnering with the MADE task group. - They can add resources and have carriers in their membership. - They have a process in place to register companies for the File Naming Protocol. Package System Calibration Standard needs to be finalized by the Test Plan Committee. Next Meeting - ISTA Conference - April 16 - Orlando, FL
