  • Patent number: 10114230
    Abstract: An eyeglass apparatus comprises left and right eyeglass portions and a link. The link is configured to permit the eyeglass apparatus to transition between an extended configuration and a collapsed configuration. In the extended configuration, the eyeglass apparatus is adapted to be worn by a user in a conventional eyeglass wearing orientation. In the collapsed configuration: an inwardly facing lens face of one of left and right lenses faces an outwardly facing lens face of the other of the left and right lenses; a medial edge portion of the left lens is closer to a medial edge portion of the right lens than to a lateral edge portion of the right lens; and the lateral edge portion of the left lens is closer to the lateral edge portion of the right lens than to the medial edge portion of the right lens.

  • Patent number: 9862441
    Abstract: A bicycle saddle includes a seat bladder fastened to a base frame. The seat bladder has one or more cavities that include an internal channel along a portion of the seat bladder's centerline that blocks the flow of fluid from side-to-side along the length of the internal channel. A rear fluid channel allows fluid to flow from side-to-side as the rider's weight shifts from side-to-side during the pedaling cycle. Fluid also flows from side-to-side where the pommel portion flows into the wider seating portion of the set bladder by moving around the forward end of the longitudinal channel. The perimeter of the seat bladder overhangs the perimeter of the base frame by a variable amount throughout the perimeter of the base frame.

  • Publication number: 20170336651
    Abstract: An eyeglass apparatus comprises first and second eyeglass portions, each having a connector portion and a lens portion. The eyeglass apparatus is configured to transition between stowed and extended configurations. When the eyeglass apparatus is in the stowed configuration, the lens portions overlie one another. When the eyeglass apparatus is in the extended configuration, the lens portions are in a non-overlying configuration.
