All electronic devices in the United States need approval from the FCC before they hit the market; it’s usually (but not always) the last stop between Engineering or Manufacturing and Sales. Google has filed an application for Glass for Enterprise, the refined business version of the Glass that the company sold to “explorers” up until early this year.
The enterprise version of Glass appears to have hinged temple bars and is generally more of a finished piece of work, water-resistant and more rugged than the first pass.
Internals of the new Glass have been previously reported, and 9to5Google says they’ve been corroborated by the Wall Street Journal. The FCC filing is still mostly safe from prying eyes — the manual isn’t publicly accessible, nor are details of the technical testing — but there are photos you can look at if you like.
Don’t count on buying this directly from Google though. This is no developer’s program. You want one of these, you’ll need to go through a Glass for Work reseller, the identity of which you can expect to hear about soon.
