The data are stored on the MXEncoder in non-volatile memory and won’t be erased until
instructed to by the HITS Software.
Communication between the MXEncoder and Sideline Receiver is sensitive to
environmental noise (i.e. other devices operating in the ISM band). The communication
link between the MXEncoder and Sideline Receiver is designed to be frequency agile,
automatically switching between various frequencies to avoid any interference. The HIT
System operates in the FCC unlicensed ISM band (902-928 MHz). Typical range is
expected to be <= 150 yards.
Data Analysis
A detailed CG (Center of Gravity) time series for any single impact may be exported to
an ASCII text file for further data analysis:
1. Select the Export command under the File Menu. This will bring up an Export
dialog box (Figure 10).
2. Select the date on which the impact occurred, the player number and the impact
ID number (which is the time the impact occurred). Once the specific impact is
highlighted, a graph of the raw data will appear. A few moments later the
processed CG time series will appear in the graph window as a thick white line.
The impact vector (magnitude, azimuth, and elevation direction) are detailed in
the Impact Vector text boxes. Head Impact Criterion (HIC) and Gadd Severity
Index (GSI) metrics will also be illustrated. Note that these metrics are
calculated using Simbex chosen metric parameters; only the CG time series is
exported to the data file. The exported CG time series data should be used with
the user’s preferred algorithms to calculate metric measures.
3. Once the desired impact has been chosen, press the Export button, which will
bring up a Save As dialog box.
NOTE: Qualification of impact data is not supported in this feature and may
be included in future releases. All impact data are currently available.
4. Save the file in the desired location. The exported ASCII data file will contain a
header with impact information (date, time, player number, impact vector, and
