5 results about "Leveler" patented technology

A leveler performs an audio process similar to compression, which is used to reduce the dynamic range of a signal, so that the quietest portion of the signal is loud enough to hear and the loudest portion is not too loud.

Control method for a levelling device

Embodiments of the present application provide a control method of a leveling device, the leveling device comprising a leveler, a spraying device and a blowing device, the leveler comprising a rack and a roller, the method comprising: when a roll changing preparation signal for the leveling device is triggered, reducing a nozzle pressure of the spraying device; when a roll changing signal for the leveler is acquired, switching the leveler from an automatic working state to a closed state; when a roll changing completion signal for the leveler is triggered, keeping the blowing device in an open state for a first time length; when a roll changing completion signal for the leveling device is acquired, keeping the blowing device in the open state for a second time length, and restoring the nozzle pressure of the spraying device after the second time length. The technical solution of the present application can realize control of the leveling device according to different signals, reduce the generation of surface indentation of the strip during production, and improve the quality of the strip.

Underwater disc leveler

The utility model discloses an underwater disc leveler which comprises a pull rod, a first cutting disc group, a second cutting disc group, a protective telescopic connecting rod assembly and a leveling roller group, the rear end of the pull rod is hinged with the first cutting disc group, and the first cutting disc group is connected with the second cutting disc group through the protective telescopic connecting rod assembly. The second cutting disc group is fixedly connected with the leveling roller group; each cutting disc group comprises a plurality of discs mounted on a transverse sleeve rod of the cutting disc group; the protection telescopic connecting rod assembly is located between the first cutting disc set and the second cutting disc set, and the first cutting disc set is controlled to steer within a certain range after being stressed through stretching out and drawing back. Longitudinal shear stress can be generated on a soil body to loosen a shallow-point soil layer, horsepower generated when a ship drags is reduced, energy is saved, and the shallow-sweeping working quality and working efficiency are enhanced by being matched with a rear roller set to work in a combined mode. And the risk of deformation and damage of the leveler is effectively avoided.

Audio device having aware mode auto-leveler

Various implementations include systems for providing enhanced aware mode capabilities in an ANR audio device. In particular implementations, a method includes receiving an ambient noise signal from a microphone associated with a wearable audio device; determining a gain value based on a sound pressure level (SPL) of the ambient noise signal; generating a gain adjusted ambient noise signal by applying the gain value to the ambient noise signal; generating a total external microphone signal by adding the gain adjusted ambient noise signal to a noise reducing ambient signal; generating an expanded audio signal by selectively adjusting a source audio signal based on a residual sound component that models sound at an ear when the active noise reduction is fully on; and combining and outputting the expanded audio signal with the total external microphone signal to an acoustic transducer.

Method and system for judging operation-to-position of land-leveler

PendingCN122330669AData setControl engineering
This invention discloses a method and system for determining the proper position of a grounding switch, belonging to the field of power system operation and maintenance technology. The method involves: acquiring a grounding switch operating torque dataset, the model of the field cabinet, and operating sound data; if the operating sound data meets preset sound triggering conditions and the field cabinet model does not belong to a preset cabinet database, then several first slopes are acquired based on the aforementioned dataset; if any of the first slopes is less than a preset threshold, then dynamic trough values ​​and real-time grounding switch operating torque datasets are acquired; if any of the real-time grounding switch operating torque data is less than the dynamic trough value, then the grounding switch operating torque data after rotation and the torque difference are acquired and verified; if both conditions are met, then the status of the grounding switch indicator light and the image of the grounding switch mechanical position are acquired; if both conditions are met, then the grounding switch operation is confirmed to be in place. This invention provides a method for determining the proper position of a grounding switch through the linkage of multi-dimensional information, enabling accurate judgment of the grounding switch's position status.
