X-bit Labs noticed Google revealed some technical specifications of its head-mounted Glass display in a filing to the FCC.
The documents reveal that the Google Glass prototype consists of off-the-shelf components made by Agilent, HP, Sunol and so on. The device features Broadcom 2.4GHz 802.11b/g/n WiFi and Bluetooth 4.0 low energy radios, power meters/sensors, a thermometer, an amplified vibrating speaker, and some other electronics components.
According to FCC, during testing for compliance “a video stored within the [equipment under test, EUT] was played on the heads-up display with audio running to the vibrating element and transmit [using] the Bluetooth LE mode”. While nothing can be said for sure at this point, but the fact that the video was “stored” on the EUT (Google Glass) means that the unit has some kind of built-in storage and maybe even a kind of application processor. Still, it is more likely that the wearable construction is just a bunch of sensors and antennas that operates like an add-on device for a Google Android-powered device.
Google requested FCC a 180-day confidentiality period for Google Glass augmented reality display, therefore it is hard to expect any additional more or less official information (e.g., photos, user manual, etc.) about the glasses any time soon.
