Dear,

I want to use sensors to measure the stature, elbow height, and
max body width, etc. Do you think that the ultrasonic sensors is suitable?
If not, what kind of sensors is suitable? Do you have any ideas? Could
you give me the information of supplier about the sensors?

Thank you for you help.


Sincerely,
Laurence

Hello
Further to your message to the "ergonomics" list, I suggest you e-mail my
retired colleague, Professor Peter Jones (P.R.M.Jones@lboro.ac.uk) asking
for whatever details you need (I advise you to be as specific and precise
as you can).

He developed an automated scanner called The Loughborough Anthropometric
Shadow Scanner (LASS) and has developed some of the most sophisticated data
handling software. A commercial version is not available unlike that
available from Cyberware in the USA.

Best wishes for your project.

Logitech makes a 6 DOF tracking device using spark-gap ultrasonic technology.
It used to be called the 'Red Baron' tracker. The problems with all these
systems is occlusion. perhaps this can be mitigated using multiple transmitter
sources but this was not available when I used this.

You might want to consider using a ERT Bird (Ascension Technology,
Vermont, USA) or Polhemus Long Ranger to digitize such
information. The downside of this is electromag. interference. If
your subjects are near metal tables or desks, you might as well forget
this option. The upside is that for these systems, the range/accuracy
is very good (given there is very little or no conductive materials
between transmitter and receiver) and occlusion is avoided (so it's
easy to digitize any side of the body.

good morning lau:
sorry but i'm not able to offer much help here -- i've worked with some of
these senesors in an undergraduate lab environment, - and while they seem
be quite senesitive i expect the relatively wide angle of the signal would
be a problem, they were using a unit from polaroid and another from pasco
scientific? - interestinly i was going to look into this this in the
near future for a project that i'm working on and would very much
appreciate a copy of any feed back that you might get, that is not
reflected in the list postings

thanx / ron rumm / perigee / victoria bc

there is a trade journal entitled, "sensors." I would try to locate a vendor
in this journal.

If you need more info let me know. I can look up the publisher info.

I will email you the information tomorow. I have a couple of these
journals at home and I am at work now.

This is what the HE-US series is used for, i.e. distance measurement. These
sensors are precise and sensitive and are easily connected to a computer.
Although institutes like NASA use our sensors with labview, we recommend that
you use a microcontroller to control and monitor these sensors, because of
requrired processor dedication and speed.
