  • Publication number: 20250096022
    Abstract: A semiconductor manufacturing system includes: a nozzle including a first channel that allows a fluid to flow through; a light source configured to emit light; and a light sensor configured to receive light, the light source and the light sensor being disposed within the first channel and opposite to each other. The semiconductor manufacturing system is configured to: emit light, by the light source, from within the nozzle toward a surface while the nozzle is dispensing the fluid; receive the light reflected from the surface by the light sensor, the emitted light and the reflected light adapted to be contained within the fluid; and examine a status of the reflected light. The emitted light and the reflected light propagate in a direction parallel to a longitudinal axis of the first channel.

  • Publication number: 20250058412
    Abstract: A laser welding mechanism includes a main body having a space and two securing devices which are respectively attached to two ends of the body. A linkage assembly includes a bearing and a linkage tube. A refraction mirror unit includes two mirrors connected to the linkage tube of the linkage assembly. A laser unit is pivotally connected to a swinging member which is connected to the linkage tube of the linkage assembly. A drive unit including a motor, a driving gear, and a driven gear. A rotation unit is connected to the swinging member of the laser unit. The laser unit rotates relative to the first workpiece and the second workpiece during welding, ensuring a stable rotation at the joining faces of the two workpieces.

  • Publication number: 20230337971
    Abstract: A detecting method for a behavior disorder event during rapid-eye-movement sleep is provided. The detecting method includes: collecting a heart rate value and a motion value of a user per epoch within a time period; generating a plurality of corresponding sleep condition values by using the motion values, to distinguish epochs into an awake period and a sleep period; transforming the motion values corresponding to the sleep period into a score according to a predetermined rule, to generate a plurality of sleep depth scores, and distinguishing the sleep period into a light sleep period and a deep sleep period by using the sleep depth scores; grouping the heart rate values corresponding to the deep sleep period as a high heart rate group and a low heart rate group; and determining, when the motion values corresponding to the high heart rate group satisfy a condition, that a behavior disorder event happens.
