Abstract: The present disclosure discloses a human-machine interaction method and system based on eye movement tracking. The human-machine interaction method comprises the following steps: acquiring first eye movement information of a user on a current display interface; executing a first operation command on the current display interface based on the first eye movement information; acquiring second eye movement information of the user on the current display interface under the first operation command; executing a second operation command on the current display interface under the first operation command based on the second eye movement information; acquiring third eye movement information of the user on the current display interface under the second operation command; locking or unlocking the second operation command based on the third eye movement information; and repeating the above process until the user finishes human-machine interaction.

Abstract: In some embodiments, a method for processing an optical fiber includes: drawing an optical fiber through a draw furnace, conveying the optical fiber through a flame reheating device downstream from the draw furnace, wherein the flame reheating device comprises one or more burners each comprising: a body having a top surface and an opposing bottom surface, an opening within the body extending from the top surface through the body to the bottom surface, wherein the optical fiber passes through the opening, and one or more gas outlets within the body; and igniting a flammable gas provided by the one or more gas outlets to form a flame encircling the optical fiber passing through the opening, wherein the flame heats the optical fiber by at least 100 degrees Celsius at a heating rate exceeding 10,000 degrees Celsius/second.

Abstract: A method of soldering one or more components to a substrate includes providing a substrate and applying an amount of solder material to the top planar surface of the substrate. One or more electrical components are mounted to the solder material in a predetermined position and orientation. A carrier is provided having one or more magnets embedded therein. The substrate is positioned above the carrier such that each of the one or more magnets is positioned directly below a corresponding electrical component. A carrier cover is positioned above the substrate and the electrical components. The solder material is heated to a predetermined temperature for a predetermined amount of time during which each of the magnets exerts a magnetic force on a corresponding electrical component to maintain its orientation relative to the substrate. The magnets reduce the occurrence of tombstoning of the electrical components during heating of the solder material.

Abstract: A packaged semiconductor includes a substrate and a first component disposed on the substrate. The package includes an underfill that is dispensed under and around the first component. The package also includes a second component disposed on the substrate adjacent to the first component that provides a border to the underfill.
