This invention discloses a tension-adaptive yarn feeding device for cotton yarn production, belonging to the technical field of yarn feeding devices. It includes: a support plate frame, mounted on a frame in a cotton yarn production workshop via several assembly trays fixed to one side; and two tensioning rollers, respectively assembled at stroke notches at the top and bottom of the support plate frame, capable of displacement along the extension direction of the stroke notches. This invention, by employing a structure of track pins and helical tracks in the adjustment assembly, directly converts the axial linear displacement of the electric push rod into the rotational motion of the transmission column, and further amplifies and transmits the motion through gear pairs. This constructs a continuous motion conversion chain from linear drive—rotational output—displacement adjustment, breaking through the traditional method of adjustment relying on multi-stage linkages or single lead screws. This gives the tensioning roller adjustment process higher response sensitivity and transmission stability, significantly ensuring tension adjustment accuracy.

The application provides a hardware-assisted cross-application sandbox penetration protection system and method, and belongs to the technical field of mobile terminal security. The method comprises the following steps: S1, collecting a memory access sequence of a process in real time through a memory label extension module, and collecting a permission combination and inter-process communication data through a kernel interface; S2, calculating a deviation value of the permission combination from a white list based on a cosine similarity, and quantifying a state transition abnormal probability of the memory access sequence by using a Markov chain algorithm; S3, performing feature fusion on the output result of S2 and the inter-process communication data, and inputting the result into a long short-term memory network model to generate a comprehensive risk score; when the score exceeds a threshold value, triggering a dynamic policy arbitration module to perform a hierarchical response action. The application has higher recognition rate and interception rate.

The invention discloses an optical modulation link control method, device and system, and the method comprises the steps: transmitting two paths of optical carrier signals to a polarized light coupling and delay module in the forward direction through corresponding optical circulators, carrying out the coupling and delay control of the two paths of signals, and outputting two paths of modulated light with the polarization planes kept orthogonal; the modulated light enters the Faraday optical rotation reflection module, and is reflected to form two paths of reflected light signals which are reversely transmitted, the two paths of reflected light signals are transmitted back to the polarized light coupling and delay module for secondary delay and partial wave control, and two paths of independent reflected light signals are output; the two paths of independent reflected light signals are reversely incident to a photoelectric detector through corresponding optical circulators respectively, and the photoelectric detector performs photoelectric conversion and signal amplification on the two paths of reflected light signals respectively and outputs two paths of delay microwave frequency discrimination signals for radio-over-fiber phase noise measurement. According to the invention, time synchronization of two paths of delay microwave frequency discrimination signals for phase noise measurement is realized, and the signals are independent and low in crosstalk.
