摘要: The present invention discloses a method and apparatus for longest prefix matching. The method includes (A) reading a current-level trie node (TNODE) in the trie, (B) determining whether an offset field of the TNODE indicates that a matched prefix exists in an upper level node and, if so, adding the offset field of the TNODE to a pointer that points to a leaf array in the upper level node, updating a current best match pointer with the computation result and executing block (C), otherwise, executing block (C), (C) determining whether the TNODE has a child node according to a child bitmap, when it is determined that a branch flag of the TNODE matches a corresponding bit of a search keyword, and (D) when it is determined that the TNODE has no child node, reading the internal bitmap of the TNODE, computing a longest matched prefix in the TNODE according to the internal bitmap and a pointer that points to a leaf array in the TNODE, updating the current best match pointer with the computation result, and computing an address of a leaf node (LNODE) associated with the current best match pointer.

摘要: A carrier tape for transporting a plurality of components includes a flexible substrate extending along a longitudinal axis of the carrier tape, a plurality of pockets formed in the substrate and spaced apart along the longitudinal axis of the carrier tape, and an adhesive layer. Each pocket includes a bottom wall and a side wall extending from the bottom wall to a top surface of the flexible substrate. The adhesive layer is disposed on the bottom wall of each pocket in the plurality of pockets, such that when a component is placed in a pocket in the plurality of pockets, the adhesive layer in the pocket permanently bonds to the component, and such that when the adhesive is exposed to UV radiation the adhesive bond strength is sufficiently reduced so that the component can be removed from the pocket.

摘要: A cover film for heat-sealing to a carrier tape for carrying electronic components is described herein. The cover film comprises a polyester base layer, a first antistatic layer disposed on a first surface of the base layer, an intermediate bi-layer structure comprising a first intermediate layer and a second intermediate layer, the first intermediate layer disposed on a second surface of the base layer opposite the first antistatic layer, the second intermediate layer disposed on the first intermediate layer opposite the base layer, a second antistatic layer disposed on the second intermediate layer opposite the first intermediate layer, and a heat-sealing layer disposed on the second antistatic layer. In an exemplary aspect, the first intermediate layer comprises polyethylene and the second intermediate layer comprises a poly(vinyl acetate) copolymer and a polystyrene-butadiene) copolymer. In another exemplary aspect, the second antistatic layer comprises carbon nanotubes in a polyacrylate binder.
