the following electronic modules suitable
for our actuators:
With these modules we cover many avionics applications which use actuation systems.
|The combination with
the mechanical hardware creates the topic
"mechatronics", where we also
include analog components (sensor operation,
filters) as well as digital components (signal
processors, controllers, serial data bus
interfaces). Another unique area covers
protective circuits for on-board electrical power
systems. Their purpose is to enable the reliability
of the actuation electronics units.
We design our electronic modules in many cases according to aviation standards (such as RTCA DO-160, MIL-STD-1275). The design principles used herein are important contributions to the reliability, especially in safety-related prototypes. The protective features lay the robust foundation to the operation in research and development.
|In a more general sense the
implementation of the control scheme is also part
of the electronics. The use of micro-controllers
(MCs) and digital signal processors (DSPs)
greatly reduce the number of components and thus
size. At the same time the flexibility of
operation and data bus interfaces increases.
In addition to the main servo electronics we often deliver specific sensor signal solutions, in many cases with micro-controllers ("embedded systems"). Such signal conditioning modules are in research and development (R&D) programmes at universities and in the industry. They process electrical signals (voltage, current) or mechanical signals (position, velocity), when no other commercially off-the-shelf (COTS) units are available. We have developed a broad range of analysing and processing units, which we can flexibly combine and adopt.
We use similar electronics modules in development projects for components in DC power supplies. It is vital to have a reliable stable power supply. So we develop different supervisory modules to monitor the supply (mainly the battery). These modules form a battery management system ("BMS") which are in experimental tests.
We use similar electronic modules in development projects with DC supplies. The need for a constant supply voltage requires some protective devices. The main component is the battery. We have developed battery management systems ("BMS") and tested.
The reliability of mobile devices can be improved by "Smart Batteries". They contain (together with the storage chemistry) vital electronic components, creating an serial bus between battery and charger. The bus mostly used is the SMBus ("System Management Bus"). As an example we present a "Smart Battery" charger ("Smart Charger").
