Abstract: A collaboration architecture supports virtual meetings, including web conferencing and collaboration. Presence information is aggregated from different types of communication services to provide a generic representation of presence. In one implementation, collaboration lifecycle management is provided to manage meetings over the lifecycle of a project. Audio options include voice over internet protocol (VoIP) and conventional PTSN phone networks, which are supported in one implementation by an audio conferencing server.

Abstract: The sand walking sandal is a hinged sandal for walking on sand having a forward sole section with a foot receiving portion located thereon and an extended forward sole width portion extending outward and laterally from the foot receiving portion. A rearward sole section has a foot receiving portion located thereon, an extended rearward sole width portion extending outward and laterally from the foot receiving portion, and a rearward sole section length extension projecting rearward from the foot receiving portion. A flexible hinge joins the forward and rearward sole sections together, allowing each of the sole sections to angularly rotate about the flexible hinge independent of each other. A foot retaining thong or footwear retaining straps are mounted on the foot receiving portion for securing a user's foot to the hinged sandal.
