Abstract: It is provided the wearable electronic device including a skeletal member comprising a temple, a frame, and a bridge; a display fixed to the temple and configured to output visible light corresponding to a virtual image; a beam steering member comprising a liquid crystal and configured to adjust a direction of the visible light traveling from an exit pupil of the display to an input grating of an optical waveguide using the liquid crystal; the optical waveguide configured to adjust a path of the visible light and output the virtual image; an infrared output unit configured to output infrared light for tracking a gaze of a user; an infrared sensor configured to detect infrared light reflected from a pupil of the user; a bend sensor connected to the temple and the frame to measure a first bending state between the temple and the frame.

Abstract: A substrate analysis system includes a load-lock module configured to load or unload a substrate on which a pattern layer is formed; a milling module configured to form a milling surface from which at least a portion of the pattern layer is removed; a depth measuring module configured to measure a milling depth of an analysis region formed on the milling surface; an imaging module configured to capture a two-dimensional image of the analysis region; and a control module controlling the substrate to circulate through the milling module, the depth measuring module, and the imaging module, when the milling depth is shallower than a set target depth, wherein the milling module adjusts a path of the ion beam so that the ion beam moves horizontally in the milling region according to a scanning profile received based on an intensity map of the ion beam.

Abstract: An electronic device and a method of waterproofing a key thereof are provided. The electronic device includes a body, a display device disposed in the body, a key disposed in the body, and a key-waterproof structure including an insert-injected product that includes an insert-injected sealing area, and a bonding area where a silicon-not-attached portion is formed. The method includes assembling a flexible printed circuit board, to which a key is attached, through a silicon-not-attached portion of an insert-injected product, which is made by insert-injecting a bracket and silicon rubber, and bonding the silicon-not-attached portion.
