System Overview
Introduction
The Ambient Environment Controller (AEC) is a device containing one temperature
sensor and four light sensors used to measure the ambient environment.
The control of the AEC is integrated into the software of the DLite Display. AECs have
been specially developed to be integratable to any tile bordering a display or even within
the display, dependent on the circumstances and facilities available. Single or multiple
AECs may be incorporated to a DLite Display, measuring the environmental light
conditions through out the day.
The modular concept of the AEC gives rise to configurations with maximum flexibility
and controllability. Screen dimensions of any desirable configuration can be rapidly
incorporated with an AEC network. The built-in intelligence of the DLite Software allows
the system to detect and configure itself regardless of the shape, size and position of
AEC modules added to the screen.
The mechanical flexibility enables easy installation and quick servicing. AEC modules
are only to be used in conjunction with BARCO DLite Modules.
Each AEC is assigned a certain representative weighting percentage, dependent on its
relevance. This percentage weighting can even be assigned individually to each of the
four light sensors. Then a weighted average is calculated from all measurements, the
software will instigate a response according to a given reaction slope. The reaction
slope determining the time of response to filter out peaks within light measurements.
The light output of the display will change accordingly to the value which the AEC is
calibrated at. The whole display or just selected portions of the display may be
programmed to react.
