Abstract: A shell structure for a thyristor trigger unit comprises an integrally-formed shell body with a holder and a cuboid structure, and a side plate. The cuboid structure is a cuboid with an opening in its front where an open face is formed at the front opening of the cuboid. The cuboid further includes a rear panel, a left panel, a right panel, an upper panel, and a lower panel. The holder includes a square retaining plate and two triangular stiffener plates. The square retaining plate is formed by a bottom panel extending towards a side of the left panel in a long side direction of the cuboid while the triangular stiffener plates are fixedly connected between the square retaining plate and the left panel. The side plate is mated with and detachably mounted on the open face to produce a sealed 6-face cuboid structure by sealing off said open face.

Abstract: A router identifies in a data packet an address of a network device. An algorithm determines that the address and a first prefix in a tree data structure match up to a first mask length of the first prefix. The algorithm maintains the first prefix in a temporary storage location if there is a match, and determines whether the address and a second prefix in the tree data structure match up to a second mask length of the second prefix, wherein an external node of the second prefix is linked below an external node of the first prefix, and wherein the second mask length is longer than the first mask length. The algorithm maintains the second prefix as a better match of the address, if the address and the second prefix match up to the mask length of the second prefix.

Abstract: A multirate network is Wide Sense Non Blocking with a new routing algorithm classifying requests into large, load greater than 1/(1+p), and small groups, where B is the upper load bound of any given request and p=.left brkt-bot.1/B.right brkt-bot.. Where B is less than 31/32-.beta./4, substantially 2.beta.n(P+1)(B+p-1)/p2 center interconnection units are restricted for carrying large requests only. For all other B, substantially 2.beta.n center interconnection units are restricted. Using this routing algorithm, general multirate WSNB is guaranteed with substantially the lesser of 2f(p)+1+3.75.beta.n and 2n.beta.(P+1)(Bp+B+p-1)/p.sup.2 interconnection units where n is the number of inlets per input stage switch, .beta. is the ratio of load capacity of external links to the input and output stages, and the load capacity of the internal links connecting the center stage to the input and output stages.

Abstract: A rearrangeable non-blocking three stage network and method for routing one or more requests between an input stage and an output stage, comprising between 3N and substantially the next largest integer of (41N-E.sub.N)/16 center stage interconnection units, where N is the greater of the inlet links to the input stage and outlet links from the output stage. Received requests are grouped by load size into a first group, a second group, and a third group with the second ground divided into a first half and a second half. The requests in the first group and first half of the second group are routed by a first set of center interconnection units, and the requests of the second half of the second group are routed by a second set of center interconnection units. The requests of the third group are routed through the first and second set of interconnection units so long as their load capacity is not exceeded, while any remaining small requests are routed through a third set of interconnection units.
