„Everything should be made as
simple as possible, but not
simpler!” (Albert Einstein)
Dealing with complexity is our
business when doing Applied
Research in various fields of infor-
mation technology! The contribu-
tions in this first international
edition of our customer magazine
visIT (bringing together „vision”
and „IT”) present problem solu-
tions where humans and techni-
cal systems carry out complex
tasks in a co-operative way.
Albert Einstein's aphorism addres-
ses the difficult tightrope walk of
designing complex systems: from
the scientist's point of view, we
want to be as complete as possi-
ble, whereas the user of such
systems would often be happy
with much less completeness for
the sake of better usability.
The Intelligent Power Hammer
represents a perfect example for
Einstein's aphorism. There are
two simple application parameters
(bit size and type of rock) deter-
mining the optimal rotation and
beat rates through an on-line
neuro-fuzzy based status analysis
and a table look-up approach for
the control of both rates.
The Mobile Optimized Content
system is able to automatically
adapt the presentation of content
to different browser and device
attributes and parameters. Com-
plex information is made as simple
as possible, while pursuing the
objective of wide information
dissemination.
We are paying a high price for an
intentional and man-made in-
crease of the complexity of our
world. The terrible events of
September 11, 2001 showed
clearly that complexity generates
vulnerability, as soon as we lack a
comprehensive understanding of
our systems and their interaction
with society and the environment.
Modeling and simulation help us
to improve our understanding of
systems which cannot be made
simpler. This is among our offers
to all of our partners: help to opti-
mize computer based technical
systems through following
Einstein's aphorism.

Automation techniques are
needed to control the steadily
growing flood of data and infor-
mation. The same is valid for video
data from cameras in diverse
applications.
The SiteView system for evaluation
of picture sequences was develo-
ped in co-operation with the com-
pany Vitracom using methods
developed by IITB; it can be confi-
gured to extract the specific infor-
mation needed by users from the
picture stream.
Originally developed for surveil-
lance purposes to trigger a specific
alarm after detection, tracking and
classification of moving objects,
it now enables many more appli-
cations.
For example in the application
area of traffic information systems,
vehicles can be counted and clas-
sified, movement patterns can be
evaluated, and the trajectories of
landing jets can be registered and
calculated.
A further application area is coun-
ting persons, for instance when

centres. The system has also been
successfully applied to sports.

For security reasons, one will al-
ways be confronted with the task
of refraining persons from certain
actions. An automatic system has
to be able to differentiate between
critical and harmless events – and
to do so without an identification
of the involved persons. The pro-
tection of personal rights and data
plays an essential role in any reali-
zation.
Nevertheless, SiteView can be
configured to indeed distinguish
harmless passers-by from potential
delinquents if there are enough
differences in movement patterns.
SiteView is able to differentiate
between harmless and menacing
actions by using sensitive areas
and measures of objects and their
velocities. Picture 1 shows a scene
www.iitb.fraunhofer.de/?693

visIT/2002international5
where the movement and object
specifications perceived by the
system correspond exactly to the
defined criteria. Especially in times
of global and incalculable threats,
a more reliable approach is requi-
red; Site View can offer a valuable
contribution.

Unfortunately, there have recently
been a lot of devastating traffic
accidents. Tragedies like the
Concorde crash in August 2000
and the catastrophe in Milan un-
derline the need for more sensor
equipment at airports. Efficient
reconnaissance has to be imple-
mented to avoid even less specta-
cular damages and losses and
reduce liability and insurance risks.
At the moment, Vitracom and IITB
are working on a system for mea-
suring trajectories based upon
SiteView, which is able to record
the complete documentation of
the landing flight.
Picture 2 shows a landing airplane
that has already been perceived
by the first SiteView system. This
technique guarantees that several
SiteView follow-ups will do a com-
plete three-dimensional measure-
ment of all relevant flight data.
Furthermore, SiteView can be
applied to document traffic statis-
tics. By precise recording of flight
paths a detailed documentation is
possible with only one camera in-
stead of many sensors (see pict. 3).
MMeeaassuurriinngg ooff VViissiittoorrssFFrreeqquueennccyy
A similar case is the measurement
of visitor frequency. „Virtual light
barriers” can be defined to deter-
mine a precise statistical docu-
mentation of customer movement,
as shown in picture 4. These num-
bers are used by marketing for an
optimization of product selection
and placement.
An additional application is in
sports: the precise movement pro-
file of a swimmer can be recorded
(pict. 5).

Steadily growing knowledge
about possible applications to-
gether with increasing computer
performance and expanded
SiteView functions will lead to
more extensive application of
SiteView in combating threats
and in movement analysis.

Competition, cost pressure and
shorter innovation cycles together
with increasing quality criteria are
defining nowadays the environ-
ment of most enterprises.
The intervals for projected re-
organizations and innovations are
steadily getting shorter, the tole-
rances are getting continuously
narrower. In this context, the
method of Integrated Simulation
is widely used to analyze complex
dependencies in an efficient way,
even before a new system is built.
Industry representatives refer to
the „digitalization of the plant“,
meaning the modelling of the
essential aspects of a plant in syn-
thetic surroundings. In the military
sector, very similar thoughts
determine the notion of „digital
battle fields“. In both cases, the
integrated use of heterogeneous
simulation systems within a com-
mon setting is the objective.
One example in the military sector
is the simultaneous use of a flight
simulator together with an anti-
aircraft simulator in a common
model landscape, e. g. for the
planning of new systems, for the
acquisition and integration of
new components and for training
in extensive surroundings.
Platform for VirtualPlatform technique GERTICO – training in
As promising as these possibilities
indeed are, the situation is as
complex as seen from a technical
point of view. Each simulator has
its very specific standard and
model world and is normally opti-
mized for a specific application
(e. g. conflict between high preci-
sion and real time).
This is no problem as long as the
simulators are used separately.
But for joint operations, efficient
infrastructures are needed to
couple distributed simulators
SSiimmuullaattiioonn iinnffrraassttrruuccttuurree
One precondition for the use of
simulators of different manufactu-
rers is the establishment of an
accepted standard.
A fundamental contribution has
been made by the US Department
of Defense (DoD), probably the
largest user of distributed simula-
tion systems, in defining the
„High Level Architecture” (HLA).
This architecture (now internatio-
nal standard IEEE 1516) describes
the basic rules for the integration
of simulators. Consequently, HLA
is the most important architecture
for the coupling of distributed,
www.iitb.fraunhofer.de/?279
heterogeneous simulation
systems. One problem is the high
access threshold for developers as
well as the availability and the
performance of the appropriate
running time environments.
CORBA (Common Object Request
Broker) has established itself as
being the most important platform
for the development of distributed
applications, and this completely
independent of the „simulation
community”. Because of its good
availability and quality of profes-
sional products, many application
developers and manufacturers of
simulators choose CORBA.
The project GERTICO, being
carried out by IITB, is expected to
build a bridge and to enable a
seamless transition from a genuine
CORBA application to an HLA con-
formable participant („HLA Fede-
rate”).
Therefore, GERTICO is a name
and a program likewise: GErman
Run Time Infrastructure is COrba.
PPrroojjeecctt GGEERRTTIICCOO
Similarly to the US DMSO, the
German Bundeswehr too, benefits
from the advantages of virtual
environments. For this reason, the
development of GERTICO has
been initiated by the „Wehrtech-
nische Dienststelle für Fernmelde-
wesen und Elektronik - i.e.”
Military Bureau for Communica-
tions and Electronics - (WTD 81).
The objective of the development
of GERTICO is a free of charge
resourcing of the basic software.
Suitable „Open Source” business
models are beingevaluated in
close co-operation with customers
and industry.
BBeenneeffiittss
The simulation infrastructure
GERTICO will offer advantages for
the providers of simulation systems
as well as for the users of integra-
ted simulators. The user is able to
build upon the assured HLA archi-
tecture and, therefore, upon an
internationally accepted standard.
The provider of simulation systems
will receive a platform with HLA
functionality imbedded into stan-
dard CORBA network services.

The Mobile InternetMobile Optimized Content
The internet with its manifold
content has great potential for
the user of mobile devices.
Sub-notebooks, PDAs and mobile
phones nowadays are able to
send and receive e-mails, to get
the latest news, to do bank trans-
actions (electronic banking), to
serve as a play station or to do
m-commerce which is the mobile
way of buying and selling.
CCuurrrreenntt ssiittuuaattiioonn
Device manufacturers as well as
content providers have not given
sufficient consideration to proces-
sing internet content with mobile
devices.
Content is often produced in
units exceeding device memory,
not all elements of the markup
language are supported by the
micro browsers of the devices,
and ergonomic requirements are
not paid attention to.
The manufacturers of mobile devi-
ces on the other hand do not
assign highest priority to existing
content when defining displays,
RAM, graphics, user interfaces,
and micro browsers.
SSttaannddaarrddiizzaattiioonn
Due to the lack of coordination of
marketing strategies between
content, browser and hardware
manufacturers, the creation of a
content standard for mobile ter-
minals is mandatory. For this pur-
pose, the Mobile Optimized Con-
tent standard has been developed
by IITB, for and in co-operation
with IMOCOS AG, Osnabrück,
Germany. The MOC standard is
able to adapt the characteristics
of content, browsers, and hard-
ware by establishing classes, so
that the utilization of the MOC of
a specific class and all the grades
beneath is guaranteed to be
problem-free for all mobile surfers.
Example: Mobile phones of the
MOC low-end range (tool range A
corresponding to the simplest
equipment) with storage capaci-
ties up to 1200 bytes are able to
store a local copy of the content
range A (1 – 1000 bytes). Larger
copies or content with images
generally cannot be processed by
these devices.
Classified content that can be
detected by search engines in the
internet and stored in databases
corresponding to its MOC range
has the advantage of fast access.
www.iitb.fraunhofer.de/?688
visIT/2002international9
The disadvantage of this pooling
into only a few classes is the inten-
tional disregard of their individual
features.
PPoorrttaallss
What does this mean for the
future? Based upon MOC classes,
it will be possible to define test
procedures for the classification
of content, browsers and hard-
ware. Based upon MOC-standards,
content providers can build por-
tals.
If hardware and browsers are
classified by MOC, too, the users
will be able to consult tables of
rated hardware by using classified
hardware in order to identify the
class of their device. Knowing this,
they can enter a portal complying
to the MOC standard through the
right access point (i.e. MOC range)
and will be offered only content
matching the device capabilities.
A quality seal according to the
MOC range would be very helpful
so that the users will be able to
easily find the content fitting their
needs.
OOuuttllooookk
Furthermore, the MOC standard
will support the CC/PP frame
(Composite Capability/Preference
Profiles ) of the World Wide Web
Consortium that will be launched
shortly.
MOC classes can be understood
as defined capacity profiles under
the terms of CC/PP and can be
attached to any internet query.
Thus, the classification of suitable
content can be automated with-
out any problem. An enhanced
application of the MOC classifica-
tion could be the introduction of
a module able to execute a con-
tent check and even change this
content if necessary so that the
device can display it without error.
The MOC standard could possibly
be the necessary connection bet-
ween users and producers of
devices and content.
If the producers of content, hard-
ware and browsers would inte-
grate the MOC standard into their
future developments, this would
help to substantially increase the
acceptance of the mobile internet.

Smart Rotary HammerFuzzy based motion control enables better
Innovative measurement, control
and diagnostic concepts have
been developed for a long time
by IITB for industrial partners.
They contribute essentially to im-
prove functionality, performance
and quality of products and
production lines and thus substan-
tially improve their market posi-
tion. One of the developments in
mechatronics will be summarized
in the following.
OOppttiimmiizzaattiioonn ooff ooppeerraa-ttiinngg ppooiinntt iimmpprroovveess tthhee ddrriillll oouuttppuutt
In order to reach an optimal drill
effect by using a rotary hammer,
it is necessary to control the two
variables rotational speed and
strike rate of the rotary hammer
in such a way that by applying mi-
nimal guidance and recoil power
a maximal drill speed in the stone
hole can be achieved. It doesn’t
matter if the tool is carried by a
human being or by a robot.
The mechanics of the robot or hu-
man being, of the rotary hammer
and of the stone form a combined
system of several elements.
An optimal drill speed is attained
for a certain combination of rota-
tional speed and strike rate.
Alterations of drill diameter and/or
material hardness lead to a false
adjustment of the system which
has to be re-optimized by an intel-
ligent re-adjustment of the two
servo-controlled drives.
In order to achieve a flexible and
automatic adaptation of rotational
speed and strike rate of the rotary
hammer to altered material and
tool types, an adaptive multi-sen-
sorc drive control has been deve-
loped by IITB in co-operation with
an industrial partner. A patent for
the concept is pending;
upon the base of a self-learning
Neuro Fuzzy component, the
measured sensor signals of the
combined system „human being –
rotary hammer-wall“ are identified.
Then, the optimal parameters of
strike rate and rotational speed
are read out of stored sets of
parameters and set automatically.
So, the multi sensoric intelligent
rotary hammer is able to recognize
itself its optimal operating point
for any wall material and tool
situation, and to re-adjust auto-
matically. Besides the maximizing
of drill performance, other quality
criteria, such as for instance the
minimization of energy in rechar-
geable battery-controlled tools,
www.iitb.fraunhofer.de/?687
visIT/2002international11
can be included in the optimiza-
tion as well.
The adaptive re-adjustement of
rotational speed and strike rate of
the rotary hammer can de done
automatically by two servo-con-
trolled drives as well as manually
via display.

The neuro-adaptive concept con-
sists of multi-sensorial online pro-
cess diagnostics in two follow-ups.
During the first step, the rotary
hammer and material type are
recognized from different sensor
signals in a fast and reliable way
by using self-learning of Neuro
Fuzzy-based online diagnostics.
To this end, the rotary hammer is
equipped with suitable sensors,
e. g. for measuring the strike rate,
the rotational speed, the longitu-
dinal and transversal acceleration.
The information provides the re-
quired data for the optimization of
the operating point of the rotary
hammer. The online diagnostics
procedure again consists of two
steps: the feature identification
and the feature evaluation. In a
second step, the related optimal
operating point for the actual

drill- and rock type is determined.
The sets of parameters needed for
the optimization of the operating
point are identified by test series
and recorded in so-called look-up
tables. The optimization includes
the minimal and maximal values
respectively of the field of para-
meters on the base of adequate
algorithms of optimization. The
result is an optimal strike rate and

Network SecurityScalable firewall systems for the protection
The security of networked IT
systems has occupied the IT world
for many years. Numerous security
products and solutions are availa-
ble on the market. The appropriate
and needed choice of security
measures and components is in-
deed decisive for the security of
the whole enterprises network.
Security measures must neither
hinder nor restrict users too much.
A too heavy restriction often leads
to a disregard of security measures.
The consequence is blatant secu-
rity faults for the entire IT infra-
structure.
A communication node has been
realized to protect the Fraunhofer
intranet, currently covering 57
institutes at more than 80 loca-
tions. The node provides the usual
internet services at the different
locations and ensures the required
protection of the IT infrastructure
and the secure communication of
institutes with their branches and
the Fraunhofer headquarters.
As for the concept and range of
the different components, great
importance has been attached
to scalable and transparent struc-
tures in order to meet all needs of
all locations and to simplify the
administration tasks. As for the
standard equipment, the commu-
nication node consists of a router
providing the internet connection,
one hardware firewall and two
communication servers.
All utilized hardware and software
components are products availa-
ble on the market that have been
integrated into an entire system.
FFiirreewwaallll
The firewall architecture of the
communication node is divided
into four security areas. The areas
ranging from least to most secure
are: the internet, the public-LAN
(in technical terminology
DMZ – DeMilitarised Zone) for
running servers open to the public
such as web servers, the institute‘s
network of work stations and
computer systems and finally the
administration network. The fire-
wall controls the communication
between these different security

areas. The standard equipment
only allows communication from
areas of higher security to areas
of lower security.
Communication relations in a
reciprocal direction, such as for
instance the access from the inter-
net to web servers in the public
LAN, have to be activated explicit-
ly. This concept allows a simple
and easy to understand rule set to
be defined.
Beside the control of communica-
tion relations, the firewall executes
secure communication via internet
of institutes with their branches
and the headquarters. This is at-
tained by encrypting the data
traffic between these locations
(VPN – Virtual Private Network).
In this case, end users need no
further measures. Based upon this
technique, home-office and mobile

to different components by the
inner communication server.
Thus, all configuration and opera-
tional data are available on the
inner server, so that only this one
has to be integrated into a security
concept. Corresponding recovery
measures ensure that the inner
communication server and, there-
fore, the whole communication
node can be restored within a
short time.
The Fraunhofer communication
node is used company-wide and
is continually improved. It has
proved itself as a stable and secure
platform for the connection of
sites to the internet.
work stations can be connected
to the institute by secure connec-
tions.
IInntteerrnneettsseerrvviiccee
The communication servers
provide the external as well as the
internal internet services. These
tasks are distributed to an outer
and an inner communication
server. The outer server is situated
in the public LAN and offers the
external services in the internet,
such as web servers.
The inner server is situated in the
inner net and provides the internal
internet services like proxy services
and internal e-mail service. In ad-
dition to this, the inner server exe-
cutes the virus check of all e-mails.
The management of the commu-
nication node is web-based, in
the inner communication node.
All configuration tasks are done
of company-wide networks

Just landed, the passengers are
restless in their seats. It is not until
the final parking position has been
reached that seat belts may be
unfastened and the passengers
are allowed to get up. In order to
reach the terminal building with
dry feet and without delay,
telescopic bridges replace more
and more the rolling gangway
and the airport shuttle bus.
High precision is required when
docking on to a telescopic bridge
- the pilot has to park precisely.
Without external help, this is diffi-
cult for the pilots who have only
a very limited field of view from
the cockpit.
While at the Fraunhofer Institute
for Information and Data Proces-
sing IITB, Dr Volker Gengenbach
developed an automatic, video-
based docking system ready for
practical application. On the final
meters and centimeters before
docking, it replaces the traditional
human guides.
The Josef-von-Fraunhofer Award
2001 was granted to Volker
Gengenbach in recognition of
this work.
Prof Nagel, a member of the
directorship of the institute IITB
till January 2000, was one of the
initiators of this ambitious project.
In the early 1980s, he developed
the foundations for a model-based
evaluation of image sequences,
together with scientists at the IITB
and the Institute for Algorithms
and Cognitive Systems in the
Faculty of Informatics at the
Karlsruhe University (in southern
Germany). Using these results,
the IITB group then concentrated
on the solution of application-
oriented research tasks. The dok-
king system works as follows. First
of all, the ground staff enters the
aircraft type and the arrival time.
Then a video camera captures the
incoming aircraft. This special
camera is located near the display
above the roll-in line in order to
capture the area of movement
from the beginning of the actual
guide line up to the docking
position.
The approach path and optimal
parking position are computed
with the aid of existing model
data.
„The path is computed 10 to 20
times per second”,

Volker Gengenbach explains.
„The system compares the ideal
and actual paths by matching the
projection of a three-dimensional
aircraft model to the aircraft con-
tours extracted from the image in-
formation. Although the amount
of data is enormous, a normal
computer can do the evaluation.”
The pilot receives only information
about distance and direction via
a display in order to execute the
needed corrections. The camera is
CMOS chip-based. It is able to pro-
cess extreme contrasts and will
even work reliably under glittering
sunlight or with limited visibility
during a snow flurry. Moreover,
the parking aid is at the same time
a parking meter. The docking
system measures the turn-around
time of the aircraft with an accu-
racy of seconds. The airport calcu-
lates the corresponding parking
fees for the airline.
This work is exemplary for the
successful co-operation between
the Karlsruhe University and the
Fraunhofer Gesellschaft on basic
and applied research.
In his spin-off company GEVITEC,
Dr. Gengenbach is adapting the
system to the specifics of the diffe-
rent airports. His next objective:
The automatic type identification
of incoming aircraft.
The system is used by Honeywell
Airport Systems Ltd at airports in
Germany, China and Korea.
