FASTER Engineering Model

The Canon EOS is connected to the EPIA via an USB port using the widely

supported Picture Transfer Protocol (PTP) developed by the International Imaging

Industry Association to allow the transfer of images from digital cameras to computers

without the need of additional device drivers. In this case the protocol has been custom

modified by Canon to fully support camera parameters control, replicating the same

functions accessible from the hardware buttons on the camera. The second USB port is

used by the touch screen interface installed on the LCD monitor (video signal passes

through the VGA port).

The EPIA is not completely fanless due to the thermal requirements of the integrated

modules, so a small 20 x 20 mm fan is mounted on the top of an aluminum heat sink

(Figure 55).

Onboard is installed a Windows XP operative system needed to run the Dynaworlds

simulation environment, the Canon camera control center and the java-based FASTER

display, which constantly monitories the entire system status (GPS and I.M.U activity,

signal quality, WAAS correction, number of received satellites, latitude, longitude,

camera arm switch position and number of acquired frames).

To display the “tunnel in the sky” pilot interface an 8.4” high brightness (1000 nit)

sunlight readable LCD is used. The open frame Litemax DLH0835 is equipped with a

LED backlight and has been selected in order to solve visibility problems encountered

inside the aircraft cockpit when incident light strikes the monitor surface (Figure 56).

Screen resolution is 800x600 pixels and the optional 4 wire resistive touch screen film is
