New Microsys occupant safety data analysis tool

Concord ON Canada, October 2, 2000 - Based on the previous Microsys Occupant Safety analysis tools used in the predecessors to SureFire, PowerPlay targets the analysis of the combined sensor and video data acquired from applications such as airbag static deployment and burst tests as well as sled, barrier, crash, pendulum, and head impact tests. Multiple PowerPlay copies can be optionally installed on multiple or networked workstations for engineering convenience.

Key benefits of the PowerPlay product include:

  • Synchronization of multiple video views and parametric sensor data streams even from different tests on different days
  • Synchronization of any open data window to any other window, either sensor data (graph) or video (image)
  • Synchronization either on a continuously "live" basis or once-on-demand
  • Adding comments to any data window (and saving the result)
  • Performing analysis such as SAE J211 filters on the trace (sensor) data
  • Performing general math functions on the trace data (optionally save the results too) such as integration, differentiation, averaging, etc.
  • Linear measurement tools for direct measurements from the video images such as distances and angles
  • Generate AVI movie loops for distribution as needed
  • Generate reports via Excel-based customer controlled-templates, quickly

"The PowerPlay analysis tool permits test operators and design engineers to quickly view and analyze data as soon as the test is finished," Microsys President Corey Miller explains. "Once the SureFireÔ test system has saved the images and data to the network drive, all data can be viewed and analyzed, with further results and comments saved as well." "Since different data types (image and sensor) from different tests (from different days or facilities) can be compared on screen, the engineer can determine how the same airbag reacts under different controlled conditions. These test variations may include temperature, squib current, or even instrument panel (IP) materials or designs." As an example, the ability to "find" the moment of maximum pressure (sensor data) and then co-relate that point in time to the actual performance of the airbag (image) provides meaningful insight for the IP design engineer.

A major advantage is the ability to "play" the images while watching the cursor value in a sensor window or vice-versa. This "live" synchronization helps the design engineer better understand the airbag activity with accurate parametric data. The trace (sensor) data is graphed and can be manipulated by processing it through standard SAE J211 filters. This filtered data can be further analyzed by applying integration of differentiation to the data to perhaps better understand the energy produced. All trace data manipulation graphed on a new graph thus no raw data is changed.

Linear measurements can be made on the digital image, once a "calibration" is performed to define a fixed distance based on a known object, say a ruler. The measurement displays both distance and angles (from bottom of frame) as well as the XY co-ordinates and time and this information is automatically added to the image frame (and can be stored). Thus, velocity or rate of acceleration of an object can be easily determined by making the same measurement on different images and noting the time difference.

PowerPlay can be used to generate reports and AVI movie loops for the distribution of the results to all interested parties. This can speed up the test cycle. For engineers, doing the analysis at their desk, instead of at the console, for maximum test flexibility while the operator sets up for the next test. An advantage of using Excel-based templates is that the engineer can modify the report structure, as needs change, without getting IT/IS involved. Generating the report is as simple as defining which image(s) and sensor data goes into what location in the report – even general information is easily accommodated.

SureFire is a configurable test system combining high-speed imaging and sensor data. Its applications include tests for most automotive interior components (occupant safety) as well as bumper tests. Other potential applications include situations where high-speed video combined with high-speed data can verify functionality of mechanical devices. This can include ordinance (explosions), large burner nozzles (for efficiency), aircraft shock testing (for failure mode analysis), and chemical dispensing patterns (for coverage and rate).

Microsys Technologies is the world-leading provider of occupant safety test systems in the global automotive market. The company has installations in all the major international automotive markets, including North, Latin and South America, Europe, and Asia.
