still alive...

sick leave this morning. my throat was burning.

back to office after lunch, nth special. however i've got a new idea to ease the effect of interference during our demonstration of mobility - that should be good enough to fulfill our requirement.

class as usual. funny part is the generation of sound waves, where signal processing is one of my interest.

canon released two new digital slr - EOS 20Da and EOS 350D. the EOS 20Da is basically the same as my EOS 20D, with the IR filter removed to facilitate astrophotography. sounds interesting, but that's not good for 'normal' photography cuz an IR filter has to be added on the lens. more importantly though, ppl can use this machine to take 'see through' photos, just like the famous sony IR capable camcoder. other than mobile phones, girls now has to face a standard studio camera that can take see-through pictures...

miss my EOS 20D. i should start taking pictures again once the weather get better.
