Abstract: The present disclosure provides a device for assisting an upper arm of a user, which includes: a support mechanism configured for supporting the device on a torso of the user; an arm link member connectable to the upper arm: a joint member coupled with the arm link member and the support mechanism, and a force generating member arranged on the support mechanism. The device, in use, transfers a load from the upper arm, through the joint member to the torso. The force generating member is configured for providing a resisting torque between the arm link member and support mechanism, and the force generating member is mechanically configured to apply a relatively larger resisting torque at a predetermined range of motion of the upper arm and to apply a relatively lesser resisting torque outside the predetermined range.

Abstract: The present disclosure provides a metal wire and a method for manufacturing the same. The method for manufacturing the metal wire includes: forming a metal bar on a substrate; forming a mask above the metal bar, a width of the mask being smaller than a width of the metal bar, and an orthographic projection of the mask on the substrate is within an orthographic projection of the metal bar on the substrate; and wet etching the metal bar to a saturation state under a protection of the mask to form a metal wire, a width of the metal wire being smaller than the width of the mask. The above method can form the metal wire with a high thickness and a narrow line width.

Abstract: An automatic detection method and an automatic detection system for detecting any crack on wafer edges are provided. The automatic detection method includes the following steps. Several wafer images of several wafers are obtained. The wafer images are integrated to create a templet image. Each of the wafer images is compared with the templet image to obtain a differential image. Each of the differential images is binarized. Each of the differential images which are binarized is de-noised. Whether each of the differential images has an edge crack is detected according to pattern of each of the differential images which are de-noised.
