The utility model relates to transmission deviation rectification technical field especially relates to a kind of deviation rectification mechanism device of roll-to-roll transmission system;Including deviation rectification subassembly and detection subassembly, the deviation rectification subassembly, the detection subassembly are all set on rack, the rack is divided into upper layer and lower layer, the both ends of the rack of upper layer are rotatably connected upper roll, the both ends of the rack of lower layer are rotatably connected lower roll, the upper roll and the lower roll are also along the length direction of the rack sliding arrangement, steel band is wound on the upper roll and the lower roll, the both ends of the upper roll are correspondingly set one deviation rectification subassembly and one detection subassembly, the both ends of the lower roll are also correspondingly set one deviation rectification subassembly and one detection subassembly;The detection subassembly is used to detect whether the steel band of its corresponding side is deviated, the deviation rectification subassembly is used to carry out position deviation rectification to the steel band deviated by detection subassembly detection;Realize the deviation rectification of steel band.

This application discloses a method, apparatus, device, medium, and product for cognitive function assessment, relating to the fields of computer and speech processing technology. The method includes: acquiring target speech data; extracting features from the target speech data according to feature categories within a preferred subset of speech features corresponding to the target cognitive test task, obtaining a target speech feature set; inputting the target speech feature set into a cognitive function assessment model corresponding to the target cognitive test task, obtaining the cognitive function assessment result of the target test subject; wherein, by constructing a multimodal cognitive database, extracting wide-area speech features from each form of speech data in the database, and based on the wide-area speech features and corresponding cognitive function assessment results, selecting a preferred subset of speech features based on the correlation strength with cognitive function, and determining the cognitive function assessment model, machine learning and statistical methods are used. This application achieves accurate and efficient cognitive function assessment.

The utility model belongs to the cigarette production technical field, specifically speaking is a kind of for forming paper deviation rectifying device, including side plate, infrared lateral deviation subassembly and deviation rectifying subassembly, the one side of side plate is connected with the guide roller, infrared lateral deviation subassembly includes adjusting support, light source generator, support plate and light source receiving end, deviation rectifying subassembly includes the plate body fixedly connected in the one side of side plate, the inside of plate body is equipped with movable slot, be provided with infrared lateral deviation subassembly, by the light emitted by light source generator, the light emitted converges on light source receiving end, if beam is partially obstructed by the measured forming paper in the way, make the light flux of photoresistor to be reduced, to produce detection signal, can accurately detect whether forming paper deviates correct position, and timely provide deviation rectifying signal, when detecting strip material deviates position, control deviation rectifying subassembly work drives forming paper to move, realize the automatic deviation detection and deviation rectifying of strip material.
