Abstract: A system and method for establishing communications channels between and among peers in a peer-to-peer networking environment. Pipes may be used as communication channels for sending and receiving messages and other data between services or applications over input and output endpoints. Pipes may be asynchronous, unidirectional, stateless and unreliable. Bidirectional pipes may also be supported. Pipes may have ends that may be moved around and bound to different peers at different times. Point-to-point and propagate pipes may be supported. Pipes may connect peers that have a direct physical link and peers that do not have a direct link. Peers may communicate through pipes without knowing on which peer a pipe endpoint is bound. A message is sent to all peer endpoints currently connected (listening) to the pipe. The set of connected endpoints may be obtained from a pipe service using a pipe binding protocol.

Abstract: An articulating knock-down frame and an improved cover design for a chair. The frame includes a pair of separate generally U-shaped frame portions, one being a seat and the other a backrest, and a pair of generally L-shaped connectors adapted for a telescopic fit with the U-shaped portions. The U-shaped frame portions are champfered about their ends to ease installation of the cover and to prevent tearing. An optional feature is also shown to facilitate disassembly, and this is a spring-loaded break joint in one or both of the U-shaped frame portions. The cover fits over the frame and holds the component parts in assembly. The cover includes a top panel section sewn against a bottom panel section, and a side panel section sewn therebetween to form an enclosure for holding an integral cushion.

Abstract: An articulating chair having a knockdown frame including a pair of separate generally U-shaped frame portions. One of the frame portions constitutes a seat and the other constitutes a backrest. The frame also includes a pair of generally L-shaped connectors adapted for a telescopic fit with the ends of the U-shaped portions to form a rigid generally L-shaped frame. A unique removable cover is also provided to fit over the frame and to hold the component parts in assembly. The cover includes a top panel section sewn against a bottom panel section, a side panel section sewn therebetween to form an enclosure for holding a cushion there between. The cover is insertable over the frame and is pivotable relative to the frame.
