Dust on the sensor - Vibrating solution

This issue has been discussed on the cinematography.net forum in regards to the SI cameras. Apparently the CMOS sensors are 'the dust's best friend'.

They discuss a few solutions using technologies already used in SLR cameras like Canon or Olympus vibrating sensor.

I was curious to know if the Red team had taken this issue into account.
 
Well, as people with magic dust vibrating sensors find out, they don't always do the job. Just read a recent review of the new Sony DSLR where some of the pictures had great blobs of dust on them ;-)

And cleaning a sensor with a brush is an easy and painless task, even more so when there's no mirror to get in the way. If you keep the lens on, of course, there's no dust getting in. I know I can do lots of lens changes with my DSLR before I have to get my brush and hand blower out.

maybe we can have some kind of automatic system (something like an automatic door/shutter), that prevents the dust to getting the sensor when we change the lenses.
 
Brainstorming now... how about a port on the side of the camera that one could shoot compressed air into which would then direct this stream of air over the sensor?

I kinda like that idea, it sounds original!
 
What about creating a small electronic charge over the exposed area where the lense or cap resides when nothing is present, thus causing electrostatic to stop dust from entering. When you take off the lense or cap it turns on and when you replace them it turns off again... Doubt this would work but if we're gonna talk hair brained ideas it sounds like it might :)
 
how about an acid sticker, with one side of the sticker being neutral and stick to the sensor, the other has a block of acid. and it would just engulf anything that lays on it, after the reaction the salts would evaporate or gather at an end for later clean up. =p

or how about getting a mini light saber, and hooking it up as a small windsheild.
 
I really doubt that at this late stage of the game they are looking to incorporate new hardware solutions, however, if there were already an active cooling device (positive displacement type) in the design, it might be able to be used to create an increased internal pressure. This would discourage the ingestion of dust when a lens change was occurring.
