  • Patent number: 8925956
    Abstract: A snowshoe/ski that allows a rider to glide and turn going downhill as well as to climb and navigate a variety of terrain in varying snow conditions. At its base is a center ski which operates on hard-pack snow surrounded by an integrated outer ski or hull that creates buoyancy in deep powder preventing the device from sinking. The center ski has a fine scaled traction area under the foot zone that allows it to slide forward but not backwards. The underside of the main body has an exaggerated version of this traction extending a little beyond the foot zone but away from tip and tail granting maximum glide. The top of the device has a convex shape keeping unwanted snow from building up and weighing down the wearer. The present invention thus relates to a hybrid device that combines elements from snowshoes and cross-country and/or downhill skis.

  • Publication number: 20100133098
    Abstract: Analytical methods and devices are disclosed for separating low abundance analytes by electrophoretically driving the analytes through a sieving matrix to first remove high molecular weight species. Subsequently the remaining low abundance analytes are electrophoretically focused onto a capture membrane where the analytes become bound within a small capture site. After this step the capture membrane may be allowed to dry and then attached to a conductive MALDI sample plate.
