Pumping water for irrigation is the larg-
est use of on-farm agricultural energy in
California. Growers are fully aware of
the need for increasing overall efficiency
of their pumping plant (pump and motor
combination), but they do not always
know how to achieve it. This Application
Note describes some specific meas-
ures.

Transformerless Power Supplies: Resistive and Capacitive
Friday, August 29th, 2008There are several ways to convert an AC voltage at a
wall receptacle into the DC voltage required by a
microcontroller. Traditionally, this has been done with a
transformer and rectifier circuit. There are also switch-
ing power supply solutions, however, in applications
that involve providing a DC voltage to only the
microcontroller and a few other low-current devices,
transformer-based or switcher-based power supplies
may not be cost effective.

Transformerless power supply
Friday, August 29th, 2008In most non-battery applications, the power to the
microcontroller is normally supplied using a wall
mounted transformer, which is then rectified, filtered
and regulated. In most applications, this method of
generating the regulated voltage is cost effective and
can be justified. However, there are applications where
the PIC12/16/17 is the main controller and low voltage
is not required by other components except the PIC12/16/17.

Infrared Tracking and Remote Control
Friday, August 29th, 2008Tracking, also called position and orientation tracking or position tracking and mapping, is used in Virtual Environments where the orientation and the position of a real physical object is required, for example to interact directly with the 3-D objects rendered by the virtual environment system. An optical tracking system has been developed in the laboratory of Virtual Environments (VE) of the Fraunhofer Institute for Media Communication in collaboration with the Russian Institute of Computing for Physics.

Edge-based partition coding for fractal image compression
Thursday, August 28th, 2008The particular feature of our approach is the adaptive spatial partition that
proceeds in a split /merge fashion. In previous split /merge partitions for fractal image coding, the merging started from a uniform partition consisting of square blocks of equal size. In this paper, we base the block merging on an adaptive quadtree partitioning. An efficient encoding method for the quadtree-based split /merge partitions is proposed which generalizes the coding of region edge maps and which includes special context modeling. The encoding method may be used for other applications that rely on image partitions.Key words: Fractal Image Compression, Partition Coding, Region Edge Maps, Image Segmentation.
