Coding of X-Sensor Jacket pressure measurements

[DiVe]

Dear Colleagues,

There is a request of channel coding of measurements coming from the X-Sensor device that is currently in use at IIHS:

(Annex A from IIHS Moderate Overlap 2.0 rating protocol)

Naming concept could be like load cell barrier in col x row in FL1+FL2, but without percentage, but simple increased numbering.
Origin and orientation of counting must the be defined.

Current points of investigation:
- which export formats are avaiable
- is the complete measurement for each sensor available over time available for export or only maximum values in a time range

Kind regards,
Dirk

After the ISO MME TF meeting (2024-02-14) I have added to the database 1.6.3p1 the following FL3 coding:

Hi All, I have the following proposals for two metrics from xsensor jacket that are used in IIHS testing. I attempted to align this with the RED‑E document; however, I am not fully familiar with all of the requirements, so I would appreciate any feedback.

Both these metrics are developed and used for HIII 5th dummy only hence I have HF in there instead of ??

Belt position:
This is a distance measurement in Z direction (DCZ). We get this by processing the data from xsensor jacket mounted on dummy's chest. One alternative can be ??CHSTBEPOHFDCZX, but I was not sure if CHST only reserved for sensors inside the dummy?

Chest Index:
This is caluclated from belt position and thorax compression channels.
