摘要： A buffer includes a plurality of serial inputs, a plurality of de-serializers, each coupled to a respective input, a plurality n of buffers and a media access controller having inputs coupled to the plurality of de-serializers, data outputs coupled to the buffers, and two control outputs coupled to respective buffers for buffering input data at a clock rate one-nth that of the input data. Preferably the buffer is a bifurcate buffer. In operation, serial packets are received on a port. They must be converted to parallel data for processing by conventional CMOS logic, however there are limits serial to parallel conversion ratio. This buffer describe circumvents theses limits.

摘要： A space switch includes a buffer having a plurality of serial inputs, a plurality of de-serializers, each coupled to a respective input, a plurality n of buffers and a media access controller having inputs coupled to the plurality of de-serializers, data outputs coupled to the buffers, and two control outputs coupled to respective buffers for buffering input data at a clock rate one-nth that of the input data and a switch fabric connected to the buffers for matching buffer data throughput with switch data throughput. Preferably the buffer is a bifurcate buffer. This space switch described ensures matching of buffer and switch fabric throughput.

摘要： A sleeving apparatus is used to place sleeves about looped belts. A bel t manipulation apparatus receives a resilient belt to be sleeved in an undeformed condition. As the belt advances through the belt manipulation apparatus, it is squeezed to form a protruding bight, in the form of a tongue, that is of a size to slide into a rectangular opening or passage defined by the four walls of a sleeve. A sleeve holder located adjacent to the belt manipulation apparatus maintains a sleev e in position to receive the belt to be sleeved. The belt manipulation apparatus urges or feeds the tongue forward into, and through the passage defined by the sleeve . As the tongue extends beyond the exit of the sleeve, it seeks to resume its undeformed shape and consequently, it forms a bulge or loop of increasingly large dimensions. When the belt is released from the belt manipulation apparatus and permitted to assume its position of lowest energy storage, a loop will have been formed at both ends of the belt and the mid-portion or waist of the belt will be constrained by the margins of the sleeve.

摘要： An arbiter for a space switch comprising a two buffers, a media access controller having data outputs coupled to the two buffers, and two control outputs coupled to respective buffers for buffering input data at a clock rate one-half that of the input data and a switch fabric connected to the two buffers for matching buffer data throughput with switch data throughput, the arbiter comprising first and second schedulers, each scheduler includes a plurality of inputs for connection to the two buffers for receiving requests, a plurality of outputs for granting requests and a plurality of inter connections to each of the plurality of schedulers for informing them of grants and logic for logically grouping input ports associated with a bifurcate input port, logically grouping output ports associated with a bifurcate output port, establishing round robin pointers for each of two alternate clock ticks for tracking next allowable requests and on one clock tick allowing connection requests from input ports to output ports and accepting a connection request in dependence upon the grouping of the input and output ports and the round robin pointer. The arbiter can be generalized to an n-furcated switch having n- furcated ports where n is an integer greater than or equal to two.
