Right this moment's helmet cams are compact, sleek, lightweight and usually waterproof, however like all great modern know-how they started out a lot in a different way. The truth is, helmet cam pioneer, mountain biker and video enthusiast Mark Schulze kicked off the observe in 1987 by bolting an outdated-faculty VHS digital camera to his bike helmet.

Those extra pounds have been just the start, although, since wireless expertise wasn't exactly obtainable back then, both. Schulze really positioned a VCR, linked by cables to the camera, in his backpack and schlepped that round as properly.

RIM's push expertise is similar to, but extra complex than, the expertise NTP has patented. NTP had accused RIM of patent infringement, and judges and Memory Wave Method juries agreed.
