Crow, the patent examiner clearly states that if they use the term "at least one meter" instead of "significant distance" that it would be acceptable.
The examiner references paragraphs 22 & 25 of the application where it states the stand-off distance is one to two meters (depending on conditions) with a integration time of 5-45 seconds.
I'm not sure why it's taking so long to make the correction!
Maybe they need another three months to think it over! LOL
