This invention relates to the process and the devices (23, 230) for applying print marks along the conveying direction by printing elements (70, 170) on the articles (21, 210.1, 210.2; 90) conveyed in a predetermined conveyor speed of the tobacco processing industry, in particular wrapping strips (21, 210.1, 210.2), preferably cigarette paper strips or a rod-shaped smoking article (90). The method is realized by reduction of a relative speed between the printing elements (70, 170) and the articles (21, 210.1, 210.2; 90) to be printed in the printing process along the conveying direction. The invention relates to a machine in the tobacco processing industry, in particular cigarette rod forming machine or a filter installing machine.

The present invention provides an RFID (Radio Frequency Identification) tag structure suitable for determining the authenticity of goods or parts, and also provides an information processing system for reading RFID tags that can accurately perform read-only RFID tags Authenticity determination of goods or components. A plurality of RFID tags are designed to have a service identifier and service data as tag information, each RFID tag holds tag information in a ROM (Read Only Memory), and responds to tag information via radio waves upon receiving radio waves from a reader, The service identifier designates a common utilization target with the same value, and the service data sets different values ​​for each RFID tag. Then, by dividing the data structure of an RFID tag with a read-only memory into a service identifier and serial data, it is possible to confirm that the commodity is genuine by simply confirming the service identifier, which is common to a certain commodity, and the serial Data is used to manage individual products.

The disclosure provides an image comparison method, an image comparison device, electronic equipment and a medium. The image comparison method includes: obtaining a seal image to be detected, and obtaining a reserved seal image corresponding to the seal image to be detected; obtaining the rotation angle of the seal image to be detected relative to the reserved seal image; obtaining the rotation angle of the seal image to be detected the degree of coincidence with the reserved seal image; and determine the authenticity of the seal image to be detected based on the degree of coincidence.

The invention provides a video cover verification method, a video cover verification device, a server, and a terminal, which are used to solve a technical problem of conventional video cover verification methods of low efficiency. The video cover verification method comprises steps that a video flow uploaded by a user, the cover image frame of the video flow, and the time stamp of the cover imageframe are acquired; the image frame corresponding to the time stamp is analyzed from the video flow; the verification of the cover image frame is carried out based on the image frame. The efficiencyof the video cover verification can be improved.

The invention discloses a relay performance detector, which comprises a battery, two switches, two indicating devices, two voltmeters, a relay socket, a single-chip microcomputer and a liquid crystal display; the negative pole of the battery is connected with the first contact piece of the relay socket, and the positive pole passes through two switches Afterwards, it is connected with the second contact piece, and the node between the two switches is connected with the third contact piece; the second contact piece is also directly connected with one end of a voltmeter, and the negative pole is connected with the other end of the voltmeter and the first contact piece, The fourth contact piece is connected to the negative pole through an indicating device, and the fourth contact piece is also connected to the first end of another voltmeter, and the second end is connected to the third contact piece; the fifth contact piece is connected to the battery through another indicating device. The node between the fifth contact piece and the other indicating device is also connected to the first end of the voltmeter, and the single-chip microcomputer is used to receive the voltage value measured by the two voltmeters and display it on the liquid crystal display superior. The above-mentioned relay performance detection device can truly measure the performance and quality of the relay.

The invention discloses an audio recognition method and device and a computer storage medium, belonging to the technical field of electronics. The method includes the following steps: acquiring a plurality of audio segments from a target audio to be recognized; determining a target fragment from the audio segments, wherein the target fragment is an audio fragment obtained by recording human voice;and if the target fragment in the audio segments satisfies a specified condition, determining that the target audio is an audio obtained by recording human voice. Through analysis of the audio fragments in the target audio, whether the target audio is an audio obtained by recording human voice can be accurately recognized, and the authenticity of the target audio can be determined.
