Patents by Inventor Shengxian Liu

Shengxian Liu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11421214
    Abstract: The invention belongs to the technical field of green chemistry, and provides a novel system based on a new nitrile hydratase for highly efficient catalytic conversion of aliphatic dinitriles. The invention discloses a new application of nitrile hydratase using Rhodococcus erythropolis CCM 2595 in catalyzing aliphatic dinitrile. In particular, the enzyme can regioselectivity catalyze the formation of 5-cyanopyramides from adiponitrile with high reaction rate under mild reaction conditions, which provides a new method for the industrial production of 5-cyanopyramides.
    Type: Grant
    Filed: October 25, 2019
    Date of Patent: August 23, 2022
    Assignee: DALIAN UNIVERSITY OF TECHNOLOGY
    Inventors: Changhai Liang, Li Wang, Shengxian Liu, Tongyi Dou, Changhao Cui

  • Patent number: 10601571
    Abstract: A method for synchronizing sensor data of a sensor system with the host time base of a host system, based on the clock ratio of the sensor time base to the host time base. To ascertain the clock ratio for at least two communication events, a time stamp acquisition is performed for each event, in which a sensor time stamp and a host time stamp is recorded. The communication events for ascertaining the clock ratio relate to a specific quantity of data. The ratio is ascertained/updated repeatedly; the duration of the individual communication events for the time stamp acquisition are measured; and by comparing each measured duration to a comparison value, possible irregularities in the communication event are detected. The host time stamp of a time stamp acquisition is corrected/replaced by a calculated host time stamp based on the measured irregularities. Also described is a related device for the method.
