Methods of achieving high Color
Rendering Index with LEDs
6
With standard LEDs, it is not possible to
realize LED luminaires and lamps with
both high efficacies and high CRI. This
article introduces the Brilliant Mix con-
cept which now allows to effectively real-
izing both high CRI and high luminaire
efficiencies.

Successful energy harvesting
for wireless sensor nodes
15
This article presents simple energy-harvesting techniques which
can be used to implement maintenance-free wireless sensors for
cost-effective networking in applications such as smart homes,
building automation and M2M communication.

Small form factor design trends are para-
doxical. Form factor size decreases while
required functionality increases. More pro-
cessing power is demanded while lower
power consumption and thermal output are expected. Rugged-
ness against the shock, vibration, humidity, temperature extremes
and variance inherent in mobile and outdoor applications is also
needed, facing designers with a very complex soup.
Configurable hardware for automotive
alternator regulator designs
38
The Epona alternator regulator can
increase the efficiency of generators in
24V and 12V on-board electrical sys-
tems in commercial vehicles and passen-
ger cars. A basic hardware system that
can be used in all designs is ideal here
because it can be adjusted in line with
the specific customer system by means
of software.
How to achieve fastest system startup
sequences with your embedded system
46
This article discusses how to achieve fast startup times, especially
in view of different operating systems like a general purpose OS or
RTOS. Additionally an overview is given on boot media and their
effects on startup behavior, together with practical measurements.
