Thanks for that clarification, Rick. I figured that "separation of functions" mentality was what prevented the tricorder from ever being used as a communicator on-screen. In any case, it's good to know you designed them with multitasking in mind!
Oh, and that little bit about Danar using the unconscious crewman's finger to activate the combadge has always been one of my favorite subtle nods to the more advanced security features of the combadges. Glad that one slipped through.
Actually, truth be told, that one was suggested by Robert Woodhead of Animeigo, when he came to the studio for a visit. We poked it up to the producers in a tech memo.
