Latest Patents

One of Abdullah Hashim's latest patents focuses on data transmission. This adaptive system for binary data compression incorporates a coding scheme that is simple to implement. It limits codeword length and can be implemented by software. Data compression is achieved by assigning four-bit codes to the eight most frequently occurring characters in the data and eight or nine-bit codes to the remaining characters. The code assignment is made according to a continuously updated evaluation of character frequency distribution. Additionally, run-length encoding may be used in conjunction with this technique to achieve further data compression. For transmission, error control protocols are applied to the compressed data, which may include the use of forward error correcting (FEC) coding and an automatic repeat request (ARQ) system. The data may be transmitted using a burst error control system based on interleaving, allowing a single error correcting FEC coding to correct bursts of errors characteristic of a telephone system.

Another significant patent by Hashim involves inspecting textile products. This invention allows for the inspection of textile articles for size and defects by forming an image using a video camera. It captures data representing at least salient features of the image and compares this data automatically with reference data. A selection process is then effected in accordance with the result of the comparison. Articles, such as socks, presented as a succession of imperfectly matched items can be sorted for size into categories of leg and foot length.
