Abstract: A full-range image detecting system including a planar light source, an image capturing device, a light sensing device, a processing unit and a measuring module is provided. The planar light source projects a photo image with periodical variations onto an object. The image capturing device captures a reflective photo image reflected from the object. The light sensing device detects the coordinates of at least three measuring points on the object for fitting a plane. The processing unit calculates a phase variation of the reflective photo image after phase shift, a relative altitude of the surface profile of the object according to the phase variation, and an absolute altitude of the surface profile of the object with respect to the plane to obtain an information of absolute coordinate. The measuring module detects the surface of the object according to the information of absolute coordinate of the object.

Abstract: A safety monitoring system for human-machine symbiosis is provided, including a spatial image capturing unit, an image recognition unit, a human-robot-interaction safety monitoring unit, and a process monitoring unit. The spatial image capturing unit, disposed in a working area, acquires at least two skeleton images. The image recognition unit generates at least two spatial gesture images corresponding to the at least two skeleton images, based on information of changes in position of the at least two skeleton images with respect to time. The human-robot-interaction safety monitoring unit generates a gesture distribution based on the at least two spatial gesture images and a safety distance. The process monitoring unit determines whether the gesture distribution meets a safety criterion.

Abstract: A method for managing a non-volatile memory is provided. The non-volatile memory has a number of blocks, and each block has a number of sub-blocks. The method includes a number of steps. First, a last physical address is obtained. The last physical address corresponds to a sub-block which is close to another sub-block where data is newly stored. Next, it is determined, for each sub-block of at least one block, the validity of data being stored. The at least one block is at least one neighboring block of a block containing the corresponding sub-block of the last physical address. Then, a mapping table is produced according to the step of determining the validity of data.
