2.0 SYSTEM COMPONENTS FOR TRIPOD SYSTEM
The Triax Touch "E" system consists of the Triax Touch hand held controller, a hemispherical
missile and a support tripod. Also included with the Triax Touch "E" system are an 8" x 8" rubber
reference pad, battery charger, manual drop handle and fitted carrying cases.
The hand held controller is powered by an internal rechargeable NiMH battery, and records the
results of drop tests. The LCD display will show the Peak G, HIC, angle of impact and time and
date, while the impact velocity and HIC Interval (Delta T) are shown optionally. A memory card
is used to store the results of up to 1000 drop tests, and allows the user to copy the drop test results
to the included proprietary application program running on a Windows compatible platform for
report generation and archival purposes.
Internal to the head form is a tri-axial sensor (accelerometer) which produces electrical signals
proportional to the G value of the head form's impact with the surface being tested. Circuitry
inside the head form measures these voltages, calculates Peak G, HIC, impact angle and impact
velocity and wirelessly transmits the results to the hand held for display. Affixed to the head form
is a normally on electromagnet.
This magnet allows the head form to be suspended from the lifting cable of the tripod, allowing
the user to set exact drop heights above the surface to be tested. The normally on nature of the
