The ruggedized MINIDAUŽ is available in two versions - a 32-channel system and a 96-channel system. The technical features of the two systems are identical since both systems use internally the same electronic modules and components.

The MINIDAUŽs are the heart of every crash test system. They are used to acquire the analog and digital data from the transducers that are mounted to the vehicle and inside the Dummies. The MINIDAUŽs are intended to be used on-board the crash vehicle. During the test preparation phase the systems are usually connected to the Control PC via so called trailing or umbilical cables. During the actual test it is possible to have the trailing cables permanently connected or to release the cable for autonomous operation of the whole system. In this case the internal battery of the MINIDAUŽ guarantees an operation time of at least five minutes with all sensors connected. In this case we recommend for safety and redundancy purposes the use of the K3685 on-board battery.

The MINIDAUŽ offers unique safety features for the safety of the crash test data. Each analog channel is completely independent from others by using its own programmable bridge supply, amplifier (1 to 10000 in steps of one), offset compensation circuit, anti-aliasing filter, and 16 Bit A/D-converter (12 Bit optional). In case of a cut line to the external power supply the internal rechargeable batteries will take over. The measurement data is stored in FLASH EEPROM rather than sensitive SRAM or DRAM to avoid lost data in case of a power failure after the test. 

Since 1976 Kayser-Threde has been supplying car manufacturers and test houses with ruggedized on-board data acquisition systems for use in safety tests according to SAE J 211. In the early eighties, European activities have been expanded to a world-wide operation. Today Kayser-Threde has customers all over the world such as:

Australia: Holden, Crashlab 
Germany: AUDI, BAST, BMW, Mercedes
Keiper Recaro, Opel, PARS, TÜV, Ford 
United Kingdom: LOTUS, MIRA, Transport Research Laboratory
