Abstract: A method for testing burning performance of a dark-colored cigarette using a dark-colored cigarette paper is provided. The dark-colored cigarette paper has a grayscale less than 255. The method includes: simulating, by a robotic arm, a cigarette smoking process and environment; acquiring, by a full-vision camera system, an image of a burn line and ash column region of the dark-colored cigarette; and analyzing a burning performance indicator of the dark-colored cigarette according to coordinate information of the burn line and ash column region. The method is based on a surface reflection characteristic of the dark-colored cigarette paper and a principle of optical reflection to light and highlight an edge of the dark-colored cigarette sample by a light source at a certain angle from a side. In this way, the method forms a chromatic aberration to localize the dark-colored cigarette sample, thereby testing the burning performance of the dark-colored cigarette sample.

Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.
