Abstract: The present disclosure provides an automatic speed-changing winch capable of autonomous clutch engagement and disengagement, as well as automatic speed adjustment based on different load. The winch autonomously allows the drum and gear mechanism to engage and disengage via a contact clutch. The gear mechanism automatically selects different transmission ratios based on the load on the drum: a smaller transmission ratio and higher speed under lower loads, and a larger transmission ratio and stronger load capacity under higher loads. This automatic speed-changing winch of the present disclosure can achieve these functions entirely mechanically, or through a combination of mechanical structure and electromagnetic control.

Abstract: The present disclosure provides an electric winch with autonomous clutch, which can realize the autonomous engagement and disengagement of the drum. By installing a contact clutch in the transmission assembly of the electric winch, the drum and the actuation device can be engaged and disengaged autonomously at the contact clutch position. Thus, the user can autonomously control the rope release speed when needed, and the drum can be engaged instantly by the operation of the motor when engagement is required.

Abstract: The present disclosure provides a suction pressure regulating valve and a parallel compressor system. The suction pressure regulating valve includes a valve body having a suction channel for communicating with a suction port of a compressor; a valve core disposed in the valve body and allowed to extend into and retract from the suction channel to change a flow area of the suction channel; and a rotating member rotatably connected to the valve body and cooperating with the valve core, wherein the rotating member is configured to rotate relative to the valve body so as to drive the valve core to extend into and retract from the suction channel. In this way, by using the suction pressure regulating valve, real-time regulation may be made according to different working conditions or flows, which may allow the compressor to achieve a good pressure equalization effect under various working conditions without repeated disassembly and assembly of pipelines for debugging, and to have superior reliability and safety.

Abstract: Techniques for scanning a machine learning (ML) model, which is received over a network, are disclosed. Information associated with the ML model is received. A container image is accessed, based on the information associated with the ML model. A software container is loaded using the container image. The ML model is loaded within the container. A plurality of system calls from the ML model within the container is detected. One or more system calls of the plurality of system calls are categorized as suspicious, e.g., based on the one or more system calls being outside a normal or expected behavior of the ML model. Responsive at least in part on categorizing the one or more system calls of the plurality of system calls to be suspicious, the ML model is tagged as possibly being malicious. A result indicative of the ML model being tagged as possibly being malicious is output.
