I think it's like a Merrichef/Rational type oven with simultaneous infrared/thermal/microwave cooking (think Starbucks or Subway oven). Those are made for foolproof cooking/reheating in a fast food environment (where they have the time to perfect the exact way, say, an ambient bagel needs to be optimally heated (if you've had one from Starbucks, they unwrap the bagel from the cellophane, open it up and put it cut side up on a greaseproof sheet, then "hit the proper button" which cooks for 25 seconds or so and comes out pretty tasty (evenly toasted surface, warmed throughout, not toughened or scorched). The corporate office tests all different combinations of heating; even including things like altitude, ambient temp, etc. to perfect the outcome. Kind of overkill for the home kitchen, where the expert is the cook and you're not trying for optimization over multitudinous situations/conditions/personnel.
