  • Publication number: 20230287504
    Abstract: Provided are peripheral blood miRNA markers for diagnosis of non-small cell lung cancer, wherein the peripheral blood miRNA markers comprise hsa-miR-1291, hsa-miR-1-3p, hsa-miR-214-3p, hsa-miR-375 or hsa-let-7a-5p. Five specific diagnostic markers suitable for diagnosing non-small cell lung cancer in Asian and Caucasian populations are validated on a large number of samples, and have higher population specificity compared to other miRNA markers previously reported. These five miRNA diagnostic markers are proposed for the first time and are shown to be more reliable than other miRNA molecular markers.

  • Patent number: 9923496
    Abstract: A fault-tolerant control method for a position sensor of a switched reluctance motor, if the position sensor of the switched reluctance motor runs without a fault, detecting, in real time, four equal-interval or equal-angle continuous edge pulses of an output signal of the position sensor, the fourth edge pulse being the current edge pulse, and detecting time intervals (T1, T2, T3) between each two adjacent edge pulses sequentially, thereby calculating a time interval (T4) between the current edge pulse and a next edge pulse following the current edge pulse. If the position sensor of the switched reluctance motor fails, and the next edge pulse following the current edge pulse is lost, reconstructing the next edge pulse after the interval time (T4) of the current edge pulse of the output signal of the position sensor.

  • Patent number: 9871476
    Abstract: A braking torque closed-loop control system and method for a switch reluctance motor. The closed-loop control system comprises a torque regulator, a mode selector, a current regulator, an angle optimization controller and a torque estimator. On the basis of the rotating speed of the motor, the mode selector implements a phase current soft chopper control in a low rotating speed region and an angle position control in a high rotating speed region. The current regulator performs soft chopper hysteretic current regulation. The angle optimization controller optimizes a turn-on angle and a turn-off angle of a power converter master switch to reduce torque pulsation and improve braking energy feedback efficiency. The torque estimator conducts an on-line estimation of an actual braking torque estimated value of the motor based on an actual phase voltage and current of the motor to achieve braking torque signal feedback.
