Rittal, Axiom
Sign Partnership
Agreement
LONDON, Ont. – Rittal Systems Ltd., a leading supplier of enclosure solutions for industrial
and information technology (IT) applications, has
announced a distribution partnership with Axiom
Technologies Ltd.
$[LRPZLOOFDUU\5LWWDO·VHQWLUHOLQHRIFRPSXter and automation enclosure solutions. Founded in
1979, Axiom specializes in industrial automation
for the manufacturing industry with a focus on
automation, safety systems, motor and drive technology, motor control, power distribution, sensors
technologies and additional products for machine
safety and automation requirements.
For the IT sector, Rittal recently introduced the
low-noise TopTherm Plus air-conditioning unit.
A recent survey found that more than half of Canadian professionals credit technologies such as cell phones and PDAs for keeping them connected at
work, and one in five say they rely on an ‘all-in-one’ device such as a smartphone to balance their social and professional lives. See our special Optoelectronics section (P. 8) for a sample of the new display technologies used in devices such as these.
Research Team Discovers the
Nature of Superconductors
MONTRÉAL – A team of researchers from
the Canadian Institute for Advanced Research
(CIFAR), led by Université de Sherbrooke
Professor Louis Taillefer, have laid to rest a 20year-old mystery about the nature of an exotic
class of materials known as high-temperature
superconductors.
These materials, which conduct electricity
with no resistance, hold enormous technological
promise for power transmission, levitating trains,
magnetic medical imaging, wireless communications, quantum computing, and many more
related applications. In the past, scientists have
been held back from harnessing the full power
of these materials, because of unanswered fundamental questions, such as whether these materials
are metals or insulators.
In experiments carried out at the National
Pulsed Magnetic Field Laboratory in Toulouse,
France using superconducting crystals created by
CIFAR researchers at the University of British
&ROXPELD3URIHVVRU7DLOOHIHU·VWHDPREVHUYHGD
phenomenon called “quantum oscillations” in a
high-temperature superconductor, which provide
unambiguous evidence that these materials are
metals.
“The results are crystal clear,” said Professor
Taillefer. “High-temperature superconductors
were discovered in 1987, and only now do we
finally have concrete knowledge about their deep
nature. This discovery gives both theorists and
experimentalists something real to work with.”
Superconductors are already used in MRI
scanners, trains, power lines and in other areas,

Systems Ltd., and Phil Jacques, Axiom CEO.
The units have an integrated design and contain
specially designed low noise fans, an alternative
to water-cooling with an external chiller. Units are
available for applications up to 750W.
The units are equipped with the Condensate
Management System (CMS), which eliminates
the need for condensation. CMS collects the condensation and returns it to the external atmosphere
via a heating element and routing tube. The units
are available at 230V or 115V 50/60Hz, and are
compatible with any rack with RS232, RS485 and
RS422 provision for on-line connectivity.
At the Hannover Fair earlier this year Rittal
introduced its Top console system that boasts a
range of configuration options, flexibility and a
new design. The console system has a modular,
three-part design – the pedestals, desk units and
consoles can be combined according to customer
requirements.

may are patents for methods relating to the operation of an economic enterprise. Each country has
different rules on the allowability of business
method patents. For example, the U.S. is often
considered a jurisdiction that is more receptive to
business method patents than others. Though business method patents may be issued where computers are not involved, most business method patents
involve the use of computer technology.
Patent protection may protect the method of
conducting business that is implemented upon the
Web site. For example, many readers may remember that in 1999, Amazon.com received a patent
for the concept of one-click shopping on-line. The
issuing of the patent generated a lot of controversy
as many people claimed that the subject matter
being claimed as inventive was not patentable.
Even though there was controversy, and the patent was eventually re-examined, the patent is one
example of the types of Web-based subject matter
that may be patented. Provided that the requisite
tests (that the method is novel and non-obvious)
are met, specific methods of offering goods and
or services upon a Web site may be patentable in
some jurisdictions.
As well as patents for methods of conducting
business online, there exists the potential for patent
protection for other features associated with the
Web site. For example, other features that may
be patentable include the software that is used to
implement the Web site, and any novel functionality associated with the software. Such functionality may include methods that relate to the access
and processing of data. For example, if you have
devised a novel and unobvious way of processing
a request that is received
from a user of the Web
site, this may be patentable even though the
method of processing
the request may not be
visible to the user.

The Emerging Role of Colour Sensing
in Electronics
reflection properties of the material whose colour
is being measured as well as variations in ambient
lighting. Different surface finishes and material
compositions may reflect particular wavelengths of
light differently resulting in a difference in the colour
perceived and in the colour measured. However,
since the spectral response of the colour sensing system will not match the human eye, the colour sensor
will not perceive that colour difference in exactly the
same way as the human eye.
When the possible variations are understood and
compensated for properly, colour sensors can provide accurate numeric measurements of colour. In
some cases, colour sensors can be capable of detecting more subtle differences in colour than the human
eye can and with better repeatability. This allows
colour matching to be done without the subjectivity
and variability of the human eye.
By Ray King
Colour sensing applications have increased in virtually every sector of the electronics industry. A host
of new applications has brought a dramatic increase
in the number of designs requiring colour sensors.
For example, solid state lighting applications have
opened up a whole new area for colour sensors.
The development of high-brightness light emitting diodes (LEDs) has made this technology an
attractive choice for home, commercial, and office
lighting as well as for architectural lighting. Many
colours of light, including white, can be produced
by mixing monochromatic LEDs in the appropriate
proportions. Colour sensors provide the necessary
feedback to achieve the right colour mixture by
correlating the output to chromaticity coordinates
for each of the red, green, and blue LEDs of the
luminaire. The LED output can then be adjusted in
accordance with the measured difference between
the chromaticity coordinates of the LED light mixture and the chromaticity coordinates of the desired
PL[HGFRORXUHGOLJKW7KHGHVLUHWRSURYLGH¶PRRG
OLJKWLQJ·IRUDXWRPRELOHKRPHDQGRIILFHHQYLURQments by setting the intensity as well as the perceived warmth or coolness of the light makes colour
sensing a necessity for LED-based lighting.
Liquid crystal displays (LCD) with LED backlighting have the potential to be one of the largest
users of colour sensors due to their use in mobile
products such as cellular telephones and portable
music players. Other products requiring colour
sensors for display control include notebook PCs,
computer monitors, and LCD televisions. Additional
applications include traffic lights, architectural lighting, and industrial signage. Automotive applications
include instrument panel lighting control and interior lighting.
What Is Colour Sensing?
Colour sensing is the process of characterizing
and measuring colour. There are several models
for quantifying the properties of colour. The
International Commission on Illumination, abbreviated as CIE from its French title Commission
,QWHUQDWLRQDOH GH O·(FODLUDJH LV WKH PDLQ LQWHUnational organization concerned with colour and
colour measurement. The CIE standard is based
on three imaginary primary colours that can be
ratioed to form any other colour. In displays, a
colour if often produced by using the primary
red, green, and blue (RGB) coordinates.
White light contains all visible wavelengths.
When white light passes through a prism, it is broken up into its spectral components by wavelength
On the CIE chromaticity diagram, pure
spectral (monochromatic) colours lie on the
curved border of the chromaticity diagram.
All tristimulus values can be in a two-dimensional plot of x and y chromaticity coordinates.
The Benefits Of Colour
Sensors
from shortest to longest. This rainbow effect occurs
because light is refracted in different amounts by
the prism, depending upon its wavelength. The
colour that an object appears to be depends on three
things:
1. the spectral content of the light source;
WKHREMHFW·VDEVRUSWLRQDQGUHIOHFWLRQSURSHUWLHV
3. and the spectral response of the viewer or colour
sensor.
Because colour receptors in the human eye
vary from person to person, no two people see
colour exactly the same way. Additionally, only
wavelengths of light present in the light source are
available to be reflected to the eye. Thus, variations
in the spectral content of light sources can cause the
same object to be perceived as a different colour in
different lighting even to the same person. In the
same manner, a colour sensor can map the colour of
an object to a different point in RGB colour space if
the lighting conditions are changed. Therefore, there
must be compensation for these variations, either in
the colour measurement system or in the method of
colour measurement, if an accurate and repeatable
measurement is to be made. This normally requires
either tight control of the lighting conditions or a
system calibration each time the lighting type is
changed. The calibration can be performed by having the colour sensor measure the colour of a known
object and adjusting the output of the colour sensor
to the predetermined calibration values.
To produce a consistent result, the method of
colour sensing chosen by the designer must be
capable of handling variations in the absorption and
Colour sensors allow accurate measurement of colour
and the characteristics of light. Without colour sensors, it is not possible to reliably produce a desired
colour mix of lighting over changing environmental
conditions such as temperature and device degradation over time. Individual LEDs will vary slightly in
intensity and spectral emission from batch to batch.
Additionally, LEDs degrade in intensity and experience spectral shifting over time. Colour sensors
measure the intensity of light in predefined spectral
ranges: the blue channel measures from 380nm to
550nm; the green channel from 450nm to 600nm;
and the red channel from 580nm to 700nm. The
RGB outputs of the TCS230 colour sensor can then
be used to change the LED drive signals to produce
the desired result.
Use of an infrared-blocking filter or coating on
the colour sensor will ensure that only the energy in
the visible spectrum is measured by the colour sensor. Any contribution to the measurement by infrared energy will be an error term in the colour measurement. Because different types of ambient light
contain different amounts of infrared energy, this
error term cannot simply be subtracted out unless it
is known that the colour sensor will only be used in
one lighting environment. Therefore, the most flexible and accurate colour measurement system will
be obtained by removing the infrared energy before
it gets to the sensor. Filters are available that allow
measurement of colour to very closely approximate
the perception of the human eye. Manufacturers
of semiconductor colour sensors are working on
integrating this filter function into the silicon, thus
eliminating the need for external filters to get more
accurate colour measurements.
Conclusion
Colour sensors are required if a lighting or display
system is to be able to adjust to changes in ambient
lighting or the variations and degradation of LEDs.
A typical implementation of a colour sensor in an LED backlighting application.
provide a means to compensate for the batch-to-batch
variations as well as the changes in spectral content
and intensity over time of LEDs once they are in
the field.
Display screens reproduce colour by varying the
intensity of red, green, and blue LEDs and additively
mixing the results. In a typical colour sensor, such as
the TCS230 from TAOS Inc., three separate sensors
By providing closed-loop feedback to LED lighting
systems, colour sensors will allow more reliable,
flexible, and aesthetically pleasing lighting solutions
for the home, office, automobile, and electronic
displays.

Feature
Integrating Displays in Digital
Signage Systems
By Richard E. McKay
T
here is an ever-widening array of
interactive digital signage applications being implemented today, from
advertising and brand promotion at
the retail level to HMIs for machine
control in industrial applications. Many of these
are digital media systems interconnecting multiple active matrix LCDs from centralized or
remote locations. Digital signage is not pure A/V,

technologies that have to work together seamlessly or else it is an ineffective solution.
Until recently, all of the displays used in digital
media system applications have had to be connected
to a dedicated computer and a graphics control
board, meaning that a dedicated PC system and
associated hardware have been necessary to control
the content and refresh rate of each display, permit

Linux is also possible).
The signage system equipped with this new
display interface controller-based configuration can
provide the same messages, content control and
image quality as the dedicated PC approach, but
with increased flexibility to show and manage both
still images or MPEG video (depending on the configuration selected) and provide changes or updates
in real-time.
(See Fig. 1 for example showing a 6-display
digital signage system in both configurations.)
the creation and playing of individual play lists
and assure image quality. This standard approach
includes a dedicated PC or a single board computer
(SBC) or media player, a graphics card (such as an
ARGB (analogue/digital) controller), CPU/memory,
operating system, HD or compact flash storage, and
a software application and its configuration.
Advances in flat panel display interface controllers and software applications have made possible
another type of system configuration. Here, a display such as an active matrix LCD with a unique
display interface controller can be connected via a
USB or LAN interface to a single network or office
PC with its driver package or associated application
software, which then connects to a local network or
the internet to allow content updates from remote
locations. There is no need for a PC or graphics card
at each display. Virtual graphics drivers in the application software allow it to run multiple displays as
extensions of the main desktop, as independent dis-

· After-sales: Individual service packages with
agreed availability, spare parts management, guaranteed response time, maintenance intervals and
guarantee extensions.
The new service approach benefits helps customers by providing access to appropriate software
solutions along the entire process chain. For example, RiCAD 3D provides complete design data
for all commercially available 3D-CAD systems.

The new console systems are more streamlined
than their predecessors and have a larger usable
mounting surface. For example, the desk units provide ten percent more mounting surface in the cover,
which means there is significantly more space for
components than in earlier models. In addition to
the 800, 1200 and 1600 mm widths, Rittal now also
offers a compact version with a width of 600 mm.
Also introduced was the RiTCA generation of
products including standard system solutions for
AdvancedTCA (Telecommunications Computing
Architecture) and MicroTCA in 2, 3, 4, 5, 12 and
13 U including shelf management, backplane (full
mesh, Dual Star) and ventilation concept – completely wired and function-tested. The new range
of products is complemented by filler panels, face
plates and AMC/ATCA carriers in two designs.
The 13 U ATCA systems are equipped with the
hot swap-capable, high-performance RiCool III.
With 320 m³/h maximum delivery volume and 71
mm static pressure, the efficient third-generation
ventilators offer more performance and at the same
time a reduced noise level (64 dB at full load). The
systems are offered optionally in a 2 or 4 PEM
version.
Rittal employs an innovative nanoceramic
coating to its enclosures in preparation for painting. This nanoceramic procedure has been adapted
to the pretreatment of steel, zinc and aluminum
surfaces and is replacing the conventional iron
SKRVSKDWHWUHDWPHQWLQ5LWWDO·VSURGXFWLRQSURFHVV
Due to an even coating and an increase in the surface, the pretreatment ensures excellent paint adhesion, thus providing improved protection against
corrosion. The standard Rittal surface treatment
procedure now includes the three successive stages:
nanoceramic coating; electrophoresis dipcoat priming; and a final powder coating stage.
The company also unveiled a strategic global
service organization at the Hannover Fair. The new
organization provides customers with professional
support at five global service centres, 60 subsidiaries and more than 200 partners around the world.
According to Rittal president Norbert Müller,
“We want to ensure integral customer benefits, in

At some point in the negotiation process, the
party initiating licensing negotiations is required
to present evidence of “use of invention”. The
more compelling the evidence, the greater the
chances are of success. This evidence can come
in many forms, including datasheets, standards,
and technical articles.
Unfortunately, these sources typically do
not provide enough information to produce
definitive evidence. The best option for providing evidence of “use of invention” remains
reverse engineering. While it can be costly, it
provides definite evidence of use. Quality RE
evidence remains the mainstay of most successful patent licensing negotiation or lawsuits.
RE can also be used to deny the use of patented technology. An effective defence against
an allegation of patent infringement is to invalidate the patent – and one of the most effective
ways of invalidating a patent is to show evidence of prior use of the invention.

In semiconductors, the next challenge for RE
will be the 45 nm node devices already being
ramped up to production. As the consumer
electronics industry keeps innovating, it is critical that RE keeps pace with the global market
for competitive technical intelligence and IP

Power Sources
Feature
Selecting the Right Power Supply
By Gene Pecora
I
f you think of all the video, access control,
intrusion and fire systems protecting people and property every day, you may not
immediately recognize that a low voltage
power supply is behind every one. Without
a functioning power supply these sophisticated
systems simply will not operate. When a product
specifier or integrator selects the right power
supply, they can insure the proper and reliable
functioning of the system. Not choosing well is a
critical mistake which impacts system operation,
resulting in re-work with the accompanying nonbillable labour and liquidated damages.
Our mission as specifiers
and integrators

designs that meet the needs of their customers in the
areas of budget, function and service life. A specifier

WRWDOMRE,W·VQRWMXVWDELOORIPDWHULDOVDVSHFLILHU·V
product is a solution that turns information into
real world systems, functioning 24/7. Ultimately,
the goal is customers who stay satisfied over the
long term. To do this we must strive to be the best
solution providers, and select the best equipment
for the job.
Why is the power source
so important?
For the security industry, power quality is a big
issue. A power supply that is not suitable for a
specific application has the capability of bringing a system to its knees. An improperly selected
power supply can cause system slumps and shutdowns, in addition to burning up expensive control units. The most common issues that impact
power supplies are:
· heat (too much of it)
· surges, spikes and other line transients
· ground problems
· voltage sags that under-supply input energy
· over-drawing the supply, taxing it beyond its
design parameters
· noise that reduces video quality.

competitive and replete with information that
may not be fully digested by system specifiers.
We all tend to look for amp and voltage ratings
as a sign of an adequate power supply and that
is where some falter in the process of choosing
wisely. There is a better way.
Product selection criteria
First, a power supply should deliver clean, consistent power to system components. There are
several factors that influence this performance to
D YDU\LQJ GHJUHH ORDG FRQGLWLRQ HQYLURQPHQW
and line condition.
Load condition
Specifiers should use calculators available from
equipment manufacturers to determine current
needs and wire sizing for the system devices to
be connected. The NEC (National Electric Code)
says to load circuits to a maximum of 80% of the
rated capacity. A good rule of thumb is to size for
peak demand, not average loads, and to consider
the power factor of loads. Many times peak loading occurs at system startup or when all devices
are operating at the same time. Remember to consider the likelihood of future system upgrades.
Finally, some experts say to add 30% to your
answer as a safety factor.
Environment
Installers should de-rate power supplies based
on the ambient temperature of the installation
room. Unless the manufacturer specifically states
WKHRSHUDWLQJWHPSHUDWXUHUDQJHLQWKHSURGXFW·V
technical documentation, power supplies are
generally current rated at room temperature,
20ºC. Another piece of advice offered by experts
would be to de-rate power output 5 watts for each

ment and available ventilation should be considered so adequate air flow around the supply will
always be present.
Humidity is another concern for indoor rated
supplies. The best units are rated for 90% or more
relative humidity.
Some supplies are rated to withstand extreme
outdoor conditions. They are contained within
a sealed enclosure which should be made from
durable non-metallic polycarbonate material
with stainless steel or brass hardware.
These tend to be mounted near
loads such as outdoor cameras,
and complement the professional appearance of modern
outdoor domes.
Line condition
Most fire and security
system power supplies
are switching power
supplies. A switching power supply
converts power
from your AC
line into the DC
voltages needed
to run your
system. A typical switching
power supply

power from the AC line
smoothly. It actually draws sudden
gulps of current, creating uneven loads on your
AC power lines. In the instances where you have
a large amount of equipment utilizing switching
power supplies, you can actually overheat wiring and trip current breakers because of the way
they gulp power. Good supplies have circuitry
that smoothes out the gulps to keep your AC line
better balanced.
Installers know video equipment is susceptible to damage by transient voltages and surge
currents. Noise problems are best handled by a
distributed power supply that has built-in protection for these types of events. Higher quality supplies encompass sophisticated surge protection
components. The protection module inside the
supply should employ the latest technology to
manipulate these potentially damaging voltages.
These advanced modules have three stages
of protection that work in concert to either bar
entry, redirect or absorb damaging energy. The
first stage of protection reflects energy back
down the supply line barring it from entering
the supply at all. The second stage rapidly redirects errant voltages to ground, and the third
stage suppresses remaining currents and spikes.
In addition to shielding the power supply from
this harm, the module also protects adjoining
equipment by connecting their feeds through its
protection circuits.
Other considerations
Three more elements should be considered when
selecting a power supply. The first is safety. The
selection process should preference those supplies comprising greater safety features, as the
first objective is to keep the installer and system

By way of utility organizations, the government
is aware that power supplies, like the ones used in
fire and security systems, consume energy around
the clock. As such, their cost of operation is affected
by ever increasing energy prices. In the future, much
like electric lighting products, the energy consumption of power equipment will need to be considered
in addition to the expense of purchase and installation. We are already beginning to see this trend
materialize.
On December 15, 2004 the CEC (California
Energy Commission) adopted new mandatory efficiency requirements for external power supplies
sold in California. The specification includes activeon efficiency requirements, as well as maximum
standby and no-load consumption levels. These
requirements phase in over the coming years and
will change the way these power supplies are
designed and built.

Our role as specifiers and integrators is to be the

ISOLATED DC/DC CONVERTERS
FDK Corp. has introduced the Sensei series of
isolated dc/dc converters with the announcement of the FPQN48T9R632, a 330W bus
converter in the industry-standard quarter brick
format.
The Sensei series converters are designed
for intermediate bus architecture (IBA) and
distributed power architecture (DPA) applications that require high efficiency and high reliability in elevated temperature environments.
In combination with its Senpai series of nonisolated point of load (POL) converters, FDK
can provide a complete board-mounted power
package for these architectures.
The first product in the Sensei series, the
FPQN48T9R632, is an IBA bus converter
that operates from a 36Vdc to 55Vdc input.
It delivers 32 Amperes of out- put current at a
fixed 5:1 ratio step-down
output voltage,
with an efficiency in excess of 95% and a
power density of up to 300Watts/cubic inch.
The FPQN48T9R632 converter is offered in a
2.28” x 1.45” (57.9 x 36.8mm) industry-standard quarter brick footprint and pin-out. It has
a very low body profile of 0.34” (8.7mm).
Protection features include input undervoltage lockout (UVLO), output over-current
protection (OCP), output over-voltage protection (OVP), and over-temperature protection
(OTP). Built-in current sharing enables parallel
operation without the need for external circuitry. The converter meets the basic insulation
requirements of EN60950 and features input to
output dc isolation of 1500V.
The Sensei series converters deliver fullrated output current, with little or no derating,
at high ambient temperatures without the need
for heat sinks. With a 48V DC input, the converter provides 32A of output current in ambient temperatures up to 70 degrees Celsius, with
400 LFM (2m/s) airflow. This leading-edge
thermal performance results from electrical, thermal, and packaging design
that is optimized for high density

Considerations When Paralleling
Power Supply Outputs for Redundancy
By Tom Skopal
Although the extremely high overall reliability
that can be attained with redundancy is widely
recognized, implementing redundancy is not
always as easy as it may first appear to be. In
particular, it takes more than simply paralleling
the outputs of two or more power supplies to
have a redundant power system that will function
as intended.
An isolation diode must be used in series
with the output of each power supply, for two
reasons – to avoid the possibility of the combined
output being shorted by a shorted supply, and to
prevent current from one supply flowing back
into another and reverse biasing it (which could
cause it to malfunction). However, the use of
diodes introduces a significant voltage drop in
the output voltage from the supply.
For example, a 5 volt output might drop to
only 4 volts. Using Schottky diodes can in some
cases mitigate the diode drop, but it must still
be considered. And keep in mind that the supply
must be capable of providing a voltage equal to
the sum of the voltage required across the load,
the diode drop and the drops in the wiring.
A typical power supply can compensate up to
a volt or so of drops in the wiring, but may not be
capable of compensating both the wiring and the
GLRGHGURSV$QGLI\RX·UHXVLQJUHPRWHVHQVLQJ
to regulate the voltage across the load, you might
not be able to solve this problem by simply stepping up to a supply with a higher nominal output
voltage (for example, going from a 5 volt supply
to a 6 volt supply), because then the sense lines
of that supply would try to maintain a nominal 6
volts across the load.
Acopian’s standard Redundant Systems are available with outputs from 5 to 125 VDC
and in a choice of mechanical configurations (rack mounting, wall mounting and
modular systems that can be mounted on a DIN rail).
In summary, be sure to use a supply that can
put out a voltage high enough to compensate
both the diode and wiring drops under worst-case
conditions (usually, low line and maximum load
current), and also has the desired load voltage
within its adjustment range.
0RQLWRULQJ HDFK SRZHU VXSSO\·V RXWSXW LV
also very important. Otherwise, you might not
even know that one power supply is out until the

be easily ignored. Include an undervoltage alarm

go much higher than the nominal.
Replacing an inoperative power supply while
the system remains in operation requires that
each power supply have a separate AC input
VZLWFK VR WKDW WKH LQRSHUDWLYH VXSSO\·V ZLULQJ
can be deactivated without affecting the other(s).
Similarly, it must be possible to disconnect the
inoperative supply and connect the replacement
quickly and easily, so insulated connectors that
can be easily pulled apart should be used in the
wiring to each supply. And the supplies should be
mounted in such a way that they can be easily and
quickly removed and replaced. One way of doing
this is to use thumbscrews for mounting; this also
eliminates the need for tools.
Comprehensively addressing all of these
considerations can be a lot of work. However,

standard Redundant Systems meet all of these
requirements, and are available with outputs from
5 to 125 VDC and in a choice of mechanical

Municipal/Industrial Magmeter-FMG-1000 Series
OMEGA’s newest Magmeter is simple and economical and can replace those ordinary propeller meters used in the past. The FMG 1000 Series is comprised of flanged electromagnetic
flowmeters that come in 4, 6, 8, or 10” sizes,
making them perfect for municipal or industrial
water/wastewater applications where propeller
meters have typically been used. With no moving
parts and electrodes which are designed to discourage fouling, maintenance is minimal for this
magmeter which is especially suitable for those
applications where debris or sand impede propeller meters, such as slurries or wastewater; good
also for storm water applications and chemical
processing needs. And, since they have minimal
Info Card 38
straight pipe requirements they’re very handy for
use in small spaces. The FMG 1000 also has low power requirements that make it ideal for solar
and comparable power sources. They are CE Compliant and come complete with a one year
warranty and owners manual. Optional solar kit and data logger are also available.

Integrating Displays in Digital Signage Systems

Fig. 2. Advances in display interface
controllers such as the ArtistaUSB
controllers shown here make them
the only component you need to
connect to each display kit through
a low cost hub, eliminating multiple
dedicated PCs.
every display, as well as an ARGB analogue/digital controller board. Not a lot
of flexibility and, for a multiple display
system, the hardware costs and the time
required to install all of this at each monitor can make this approach an expensive
proposition. You have to pay for each PC
or media player, plus associated hardware,
operating systems, storage and software
LQVWDOODWLRQ3OXVWKHUH·VWKHWLPHLQYROYHG
in setting each PC up individually and
configuring the software.
With the innovative flat panel display
controller solutions available today, you can
eliminate the cost of the individual PCs and
have a centrally located PC or media box
that will control all of your displays. This
can result in overall installation savings of
50-70%. The controllers are adapted and
configured to the appropriate display. For
displays with QVGA resolution using a USB
interface, the controller can be fixed at the
back of the display, forming a modular smart
display unit. With VGA and SVGA resolution displays, the controller is connected to
the display via a standard shielded interface
cable, as shown in Fig. 2.
Another thing to consider is the flexibility to add additional features, like
touch screen capability. An advanced USB
pr LAN display interface controller can
provide features like an integrated touch
screen controller to control four-wire resistive touch screens. The touch screen data
is transferred via the same USB/LAN
interface as the image data, and even the
backlight of the display can be controlled
using the same interface.
Expandability and
Installation
How many displays do you need? The
standard configuration approach with a
dedicated PC at each display has certain
advantages for digital signage applications
with only a few displays, such as a higher
bandwidth for hi-resolution video content
playback; but the number of displays that
can be connected to a computer is limited.
What if you have 10, 50, 100 or more displays? Do you need the capability to control up to 132 USB interface displays from
one PC/host/mediabox, or an unlimited
number of LAN-connected display stations
from one PC/host/mediabox?
The ability to expand the number of
displays integrated into your digital signage
system is certainly a major factor to consider.
Another is, where do I get all the components I need and how to put them together?
