  • Patent number: 12221747
    Abstract: A method for separating biomass components by a ternary system, which relates to a technical field of biomass separation, and includes the following steps of: cooking and separating a biomass raw material by using a cooking liquor consisting of organic acid, small aromatic nucleophilic organic molecule and hydrogen peroxide to obtain solid residue and extracting solution, washing and screening the solid residue to obtain paper pulp, and separating and extracting lignin and/or hemicellulose from the extracting solution. This cooking system could effectively minimize the content of residual lignin and other compounds with chromophore groups in the obtained pulp, directly producing the high-whiteness pulp with excellent performance without additional bleaching process. In addition, the hemicellulose saccharides and high-activity lignin can be also obtained, so that the method has an important significance for realizing high value and industrialization of biomass resource utilization.

  • Publication number: 20240014625
    Abstract: A method for locking repetition rate of an optical frequency comb is provided. A cavity length adjusting actuator is adopted to lock the repetition rate of the optical frequency comb. When a locking state of the cavity length adjusting actuator is in a critical threshold state, an optical delay line of an optical frequency comb optical system is adjusted to adjust the repetition rate of the optical frequency comb, so as to keep locking the repetition rate of the optical frequency comb. A locking device of the repetition rate is also provided, in which an optical delay line control system can judge the locking state of a cavity length adjusting actuator control system in real time, such that the repetition rate can be slowly adjusted within a wide range, and the locking state of the optical frequency comb can be maintained.

  • Patent number: 11821729
    Abstract: A tight-integrated navigation method assisted by Elman neural network when GNSS signals are blocked based on the tight-integrated navigation system model of the INS and GNSS, where the dynamic Elman neural network prediction model is used to train the inertial navigation error model and the GNSS compensation model, so as to solve the problem of tight-integrated navigation when the GNSS signals are blocked. When the GNSS signals are blocked, the trained neural network is used to predict the output error of GNSS and compensate the output of inertial navigation, so that the error will not diverge sharply, and the system can continue to work in the integrated navigation mode. The low-cost tight-integrated navigation module is used, and the collected information is preprocessed to form the sample data for training the neural network to train the Elman neural network model.

  • Patent number: 11782011
    Abstract: An electrochemical biosensor includes a working electrode modified with a redox polymer and amine-terminated capture aptamer specific for a particular detection target. The binding sequence of the capture aptamer is also complementary to part of a second ssDNA which is labeled with HRP (horseradish peroxidase). The capture aptamer will form dsDNA with the HRP-labeled ssDNA and bring HRP into electrical contact with the redox polymer and the electrode. Prior to capturing the detection target, addition of H2O2 will lead to the highest reduction current due to the redox polymer-mediated, enzyme-amplified electroreduction of H2O2.

  • Patent number: 9965156
    Abstract: Techniques for push-pull type gestures are described. In embodiments, a push gesture away from a cursor object that is displayed by a display device is recognized. An assisted location object is then displayed to assist a user in repositioning the cursor object based on the push gesture. In implementations, a prompt gesture is recognized effective to cause a prompt object having one or more options to be displayed. The options that are displayed are selectable to initiate a function that is operable using the cursor object. In addition, a motion select gesture that selects one of the options is recognized effective to replace the prompt object and initiate a function corresponding to the selected option. Also, selected text is automatically divided into a plurality of vertical sections that are individually selectable to include or exclude when performing a subsequent function, and then the subsequent function is performed.
