    摘要: A code tree of two-dimensional orthogonal variable spreading factor (2D-OVSF) code matrices for a multicarrier direct-sequence code-division multiple-access (MC-DS/CDMA) communications system is generated by providing two sets of 2×2 orthogonal matrices {A(1)(2×2), A(2)(2×2)} and {B(1)(2×2), B(2)(2×2)}. The first set of 2×2 matrices is used to generate a pair of sibling nodes in the code tree that respectively represent matrices A(1)(2×2α) and A(2)(2×2α) by iterating the relationship: A(1)(2×21+β)=[A(1)(2×2β)A(2)(2×2β)], The matrices A(1)(2×2α) and A(2)(2×2α) are A(2)(2×21+β)=[A(1)(2×2β)−A(2)(2×2β)]. used to generate a child node of one of the sibling nodes. The child node contains an M×N matrix, which is found by iterating the relationship: A(i−1)(O×P)=[B(1)(2×2){circle around (×)}A(i/2)(0/2×P/2)] where {circle around (×)} indicates a Kronecker product. A(i)(O×P)=[B(2)(2×2){circle around (×)}A(i/2)(0/2×P/2)],

    摘要: A slurry residence time enhancement system for a chemical mechanical polishing apparatus having a base, a platen on the base, a polishing pad on the platen and a polishing head over the polishing pad is disclosed. The system includes at least one slurry distribution unit having a slurry distribution member for positioning on the polishing pad. In operation of the CMP apparatus, the slurry distribution member redirects polishing slurry on the polishing pad to the polishing head. The system may alternatively or additionally include a rim for upward extension from the base and a seal for insertion between the platen and the polishing pad adjacent to the rim.

    摘要: An organic semiconductor infrared distance sensing apparatus and an organic infrared emitting apparatus thereof are disclosed. The organic semiconductor infrared distance sensing apparatus comprises an organic infrared emitting apparatus and an organic infrared receiving apparatus. The organic infrared emitting apparatus has a positive electrode layer and a negative electrode layer to form an electric field, and organic light emitting molecules are sandwiched between the two layers and correspond to the positive electrode layer and the negative electrode layer. Under a positive bias, a plurality of electrons and holes are respectively injected from electrodes and recombine with each other to emit photons. An infrared organic conversion layer absorbs and transfers the energy to infrared emitting molecules to emit infrared light. The organic infrared receiving apparatus receives the infrared light reflected by an obstacle to generate photocurrent which varies with distance, thereby sensing the distance between the obstacle and the apparatus.
