All the image-generation electronics, the laser engine and other optics can be put into a compact, battery-powered box, that can be clipped onto the wearer's belt. Laser-generated video is then transmitted to the headset display via optical cable, before ultra-thin wedge optics display the image in the glasses.

With a thickness of just 2mm on the optical display element, Apple's patent design means that the display could be the same size as a pair of spectacles. When not being used, the optical display elements become transparent, meaning that you can transform the headset from common-or-garden reading glasses to a display in just the flick of a switch.

The NYC logo which, ironically enough, seems to be an apple drawn from an infinite loop, (ha!) has been appearing on bus shelters, hybrid taxis and shopping bags from Whole Foods. The Cupertino gang's claim for trademark infringement is, however, hard to prove with a logo, as its key issue is likelihood of confusion or dilution, according to an SF lawyer specializing in trademarks.

This dispute is the third time Apple has been involved in trademark infringement claims—remember its battle with the Beatles' Apple Corps, and Cisco Systems about who had the right to use the iPhone name?

The GreeNYC campaign applied for a trademark on its logo back in May 2007, whilst Apple's opposition, and NYC's counterclaim was filed four months later, on September 18. Next step, apparently, is to commission some independent surveys, known as mall-stop surveys, to see if Apple has a leg to stand on. The final decision will be made by the Trademark Trial and Appeal Board of the patent office. [Wired]
