In a flame identification method and device for identifying any flame image in a plurality of frames captured consecutively from a monitored area, for each image frame, intensity foreground pixels are obtained based on intensity values of pixels, a fire-like image region containing the intensity foreground pixels is defined when an intensity foreground area corresponding to the intensity foreground pixels is greater than a predetermined intensity foreground area threshold, and saturation foreground pixels are obtained from all pixels in the fire-like image region based on saturation values thereof to obtain a saturation foreground area corresponding to the saturation foreground pixels. Linear regression analyses are performed on two-dimensional coordinates each formed by the intensity and saturation pixel areas associated with a corresponding image frame to generate a determination coefficient. Whether a flame image exists in the image frames is determined based on the determination coefficient and a predetermined identification threshold.

An air purifier with an integrated air filtering mask includes a housing having a housing-base and a housing-body. The housing-base is provided with a filter-tube coupling portion and a plurality of air inlet holes around the filter-tube coupling portion. The housing-body is provided with a fan receiving slot and a plurality of air owlet boles passing through the fan receiving slot. A fan is disposed in the fan receiving slot. A casing has'a mask and a conduit. The mask is detachably coupled with the fan receiving slot, and is provided a circulation port and a window. A first port of the conduit is detachably coupled with the filter-tube coupling portion of the housing. A second port of the conduit communicates with the circulation port of the mask. An air filter is disposed at the first port of the conduit.

A test fixture is mounted to a supporting base and adapted for holding an electronic device, such as a laptop computer, a mobile phone and so on, on the purpose of testing an antenna characteristic of the electronic device. The test fixture includes a first fixing component and a second fixing component. The first fixing component is adapted for being mounted to the supporting base and has a first basic plate adapted for carrying the laptop computer. The second fixing component is removably mounted to the first fixing component, and has a plurality of supporting rods suspending above the first basic plate adapted for clamping the mobile phone therebetween.
