Abstract: A wave energy converter apparatus includes a platform that is configured to float below an upper liquid surface of a liquid responsive to the wave energy converter apparatus being disposed in the liquid. The wave energy converter apparatus further includes support structures mounted to an upper platform surface of the platform. The wave energy converter apparatus further includes a supporting shaft coupled to the support structures, the supporting shaft being disposed along an axis. The supporting shaft is configured to be oriented with the axis substantially perpendicular to direction of waves of the liquid. The wave energy converter apparatus further includes a helical member rotatably coupled to the supporting shaft and configured to rotate about the axis. The wave energy converter apparatus further includes an electrical rotary generator coupled to the helical member. The electrical rotary generator is configured to generate electricity responsive to rotation of the helical member.

Abstract: A receptacle for the collection of litter or the storage of loose items in a vehicle interior is disclosed. The receptacle comprises a container with an integrally formed flap for suspending the container from a vehicle door for convenient access by a vehicle occupant to the container interior. The flap includes a tab which engages the vehicle door window slot and which provides a wedged attachment within the door when supporting heavier loads.
