Abstract: An anonymous authentication method is implemented by an authentication device that has a key array. The key array has multiple array dimensions each having multiple device keys. The method includes: receiving ciphertexts from a chip that has multiple chip keys; acquiring authentication keys by: for each of the ciphertexts, performing trails of decryption using the device keys of one of the array dimensions that corresponds to one of the chip keys used to generate the ciphertext one by one until obtaining one of the device keys that successfully decrypts the ciphertext to serve as one of the authentication keys; and obtaining, for authentication, information associated with the chip according to the authentication keys.

Abstract: In an image deblurring method, an image processor determines an absolute difference between a pixel value of each pixel in a current image frame and a pixel value of a corresponding pixel in a reference image frame to obtain a total absolute difference corresponding to the current image frame by summing up the absolute differences corresponding respectively the pixels of the current image frame. When the total absolute difference is smaller than a predetermined first threshold value and not smaller than a predetermined third threshold value, the image processor generates an interpolated image frame based on the current and reference image frames using one of unidirectional motion estimation and bidirectional motion estimation.

Abstract: 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.

Abstract: A manipulator with three degrees of freedom includes three actuators connected to a moving platform at angularly spaced apart positions that form vertices of a first regular triangle and connected to a base platform at angularly spaced apart positions that form vertices of a second regular triangle. A normal line through a centroid of the first regular triangle is aligned with a normal line through a centroid of the second regular triangle when the moving platform is at an initial position. A control method for the manipulator includes configuring the manipulator to compute respective lengths of the actuators based upon a desired roll angle, a desired pitch angle and a desired heave height, and to set the actuators to the respective lengths so that the moving platform moves to the desired roll angle, the desired pitch angle, and the desired heave height with respect to the base platform.
