For
our gait and balance users NetForce expedites your
data gathering process and helps organize and maintain your valuable test
results and subject information. NetForce
interfaces directly with AMTI's BioAnalysis program
with a single click of the mouse. Our
multiaxis transducer users find that NetForce is
the fastest way to get a project up and running. In a matter of minutes you will have real
time display of up to 36 channels (the number of channels is system
dependent) of force and moment data coupled with a flexible suite of data
acquisition, data display and data saving features. NetForce’s
data acquisition front end can be setup to take data from a variety of AMTI’s
signal conditioning products. NetForce provides an RS-232 serial data interface, an
Ethernet data interface and also interfaces with Data Translation’s DT3002 data
acquisition cards. To view more
detailed specifications for each of these NetForce
interfaces select the item of interest in the Data Communications column in
the table below.
NetForce’s
real time data display allows you to continuously monitor the outputs of your
multiaxis instruments. The display works
similarly to an oscilloscope used for measuring electronic signals but
instead of electrical signals, the outputs from your multiaxis transducer(s)
are displayed. As you apply a force or
load to your transducer or force platform the change in force will be
instantly displayed on NetForce’s real-time
display. If you apply an oscillating
force or a sinusoidal force that too will be instantly displayed. The
displayed data may be captured or frozen by using one of NetForce’s
triggering mechanisms. Triggering may
be activated by channel level, elapsed time, key stroke, Ethernet connection
or via an external input to one of AMTI’s signal conditioning
instruments. Once a trigger event has
been detected the data acquisition process will be halted to capture the
event of interest. The trigger
mechanism may be set to acquire a specified amount of pre-trigger and
post-trigger data as a percent of the total sample duration. The
acquired data may at any time be saved to a binary file (.BSF files
compatible with AMTI’s BioAnalysis program) or may
be exported to a text file compatible with many third party spread sheets and
analysis programs. NetForce
provides a convenient file sharing protocol which may be used to link between
NetForce and other third party software. NetForce will
automatically run a third party analysis program if you specify the program
name and path in one of the NetForce setup
screens. The file sharing scheme
allows you to write macros in your third party software to analyze the data
that you have gathered and saved with NetForce. This allows you to forget about the
acquisition process and to focus on the analysis and presentation tasks
necessary for your application or experiment. NetForce
provides personalized configuration files which allow you to save all of your
current display and acquisition settings to named files that can be recalled
in the future. This is a very useful
feature if you are using NetForce in a shared
environment or if you have multiple experimental protocols which you follow. |
