Abstract: An apparatus to implement a deflate process in a compression engine. An embodiment of the apparatus includes a hash table, a dictionary, comparison logic, and encoding logic. The hash table is configured to hash a plurality of characters of an input data stream to provide a hash address. The dictionary is configured to provide a plurality of distance values in parallel based on the hash address. The distance values are stored in the dictionary. The comparison logic is configured to identify a corresponding length for each matching distance value from the plurality of distance values. The encoding logic is configured to encode the longest length and the matching distance value as a portion of a LZ77 code stream.

Abstract: A nose pad for eyeglasses is provided. The nose pad includes a pad part, which is connected to an eyeglass frame, and a pad body filled with a buffering material. The pad body is disposed on the pad part for contacting with a user's nose. The nose pad of the present invention is applicable to all types of eyeglass frames.
