Abstract: An electronic imaging system is mountable on a user's head without eyewear. The system provides a computer monitor image or other electronic display, such as television or data display. The system provides many of the functions and advantages of known eyewear-mounted displays, but without requiring the user to wear spectacles. The system can be fit to a wide range of users without prescriptive correction or other customization.

Abstract: A bicycle helmet is disclosed having a flexible, articulated member being resiliently flexible to provide resilient forward pressure against an inwardly curved portion on the posterior of a wearer's head and a flexible connection between the articulated member and opposite sides of the shell assembly including at least one elastically elongatable strap portion for providing additional resilient forward pressure against the wearer's head.

Abstract: A bicycle helmet is disclosed having a flexible, articulated member depending from the rear of the helmet, providing a closer fit to an individual wearer's head and improving stability of the helmet on the head, particularly for mountain bike riding. The articulated member contacts the wearer's head beneath the occipital region and applies a forward and upward pressure against the head. The general embodiment of the invention includes an elastic strap stretching from one side of the helmet, across the back of the articulated member, to the opposite side of the helmet. Adjusting this strap allows the wearer to adjust the forward and upward pressure exerted by the articulated member on the wearer's head.
