Google has filed an application for Google Glass, its futuristic, Internet-connected headset, has arrived at the Federal Communications Commission, according to Engadget.
The FCC approves electronic devices that emit radio waves, making it a bureaucratic hoop that most new gadgets must jump through.
The Explorer Edition of the glasses has both Wi-Fi and Bluetooth radios, requiring FCC review.
The filing means that the search giant is one step closer to shipping developer versions of the wearable technology, which is slated to arrive at some point this year.
Engadget also noticed a reference to an "integral vibrating element that provides audio to the user via contact with the user's head," which the blog says likely relates to a bone-conduction patent from earlier this month. ("Bone conduction" is where sound is transmitted through the bones of the skull, another way humans hear sounds besides audio waves.)
