Engadget has spotted an application for Google's Project Glass approval from the FCC. It gives us a closer look at the heads-up display and it might mean we aren't far from the release of the Explorer Edition developer units. After all, Google held its first hackathon last weekend in San Francisco, with another scheduled for this weekend in NYC.
In the paperwork, it says the model (called XEB) was first tested by the FCC on November 19, 2012. The application reveals the glasses will have 2.4GHz 802.11 b/g WiFi and Bluetooth 4.0HS, but that per tests, they won't support both at the same time. The filing also discusses a vibrating element that feeds you sound through contact with your head, which could be some kind of bone-conducting piece we've seen teased out in recent patent applications. We're looking through the documents to see what else we can find, but the fact that the FCC has made this document public means it's determined that Google Glasses are safe for the public. So that January 2013 delivery date Google promised back at Google I/O for developer units might not be far off-base. [FCC via Engadget]
