  • Patent number: 11879190
    Abstract: The invention relates to a plush pile knitted product and a knitting machine for the production thereof. Said knitted product comprises knitting threads (9), weft threads (10, 11), and front (14) and rear (12) plush threads, whereas the rear plush threads (12) are cut off at given intervals (a) to form plush pile on the front surface of the product. Said knitting machine comprises a housing (26). On the housing (26), over the entire length of the machine multiple closing safety plates (23) that can move vertically, and push plates (22) for pressing the weft threads (10 and 11) are mounted. Each rear plush plate (8) comprises a cutting disc (27) to cut the rear plush threads (12). Each of the threads (9,14,10,11,12) is fed in using a separate step motor (25).

  • Patent number: 10438604
    Abstract: A speech intelligibility enhancing system for enhancing speech, the system comprising: a speech input for receiving speech to be enhanced; an enhanced speech output to output the enhanced speech; and a processor configured to convert speech received from the speech input to enhanced speech to be output by the enhanced speech output, the processor being configured to: i) extract a frame of the speech received from the speech input; ii) calculate a measure of the frame importance; iii) estimate a contribution due to late reverberation to the frame power of the speech when reverbed; iv) calculate a prescribed frame power, the prescribed frame power being a function of the power of the extracted frame, the measure of the frame importance and the contribution due to late reverberation, the function being configured to decrease the ratio of the prescribed frame power to the power of the extracted frame as the contribution due to late reverberation increases above a critical value, {tilde over (l)}; and v) apply

  • Patent number: 9930905
    Abstract: The present invention relates to a composition comprising lyophilized Lactobacilli and a plant-based food, wherein the composition is substantially free of animal products. The present invention also relates to methods of treating plant-based food by administration of a Lactobacilli and a plant medium composition. Methods of using the Lactobacilli and plant-based food composition to treat E. coli or Salmonella infection in an animal in need thereof and methods of using the Lactobacilli and plant-based food composition to reduce E. coli or Salmonella contamination in an agricultural product are also provided.

  • Publication number: 20170365256
    Abstract: A speech intelligibility enhancing system for enhancing speech, the system comprising: a speech input for receiving speech to be enhanced; an enhanced speech output to output the enhanced speech; and a processor configured to convert speech received by the speech input to enhanced speech to be output by the enhanced speech output, the processor being configured to: extract a portion of the speech received by the speech input; calculate the power of the portion; estimate a contribution due to late reverberation to the power of the portion of the speech when reverbed; calculate a target late reverberation power; determine a time ti for the estimated contribution due to late reverberation to decay to the target late reverberation power; calculate a pause duration, wherein the pause duration is calculated using the time ti; insert a pause having the calculated duration into the speech received by the speech input at a first location, wherein the first location is followed by the portion.
