    Abstract: A method for preparing a spherical aluminum nitride granule includes (A) providing an aluminum oxide powder and a resin, followed by dissolving the aluminum oxide powder and the resin in a solvent to form a mixed slurry; (B) performing spray drying on the mixed slurry to form a spherical granule; (C) performing carbonization on the spherical granule in an inert atmosphere to form a carbonized spherical granule; (D) performing carbothermic reduction on the carbonized spherical granule in a nitrogen atmosphere to form a spherical aluminum nitride granule; (E) performing a densification sintering thermal treatment continuously on the spherical aluminum nitride granule in a nitrogen atmosphere; and (F) performing decarbonization on the densified spherical aluminum nitride granule in a nitrogen atmosphere to form densified spherical aluminum nitride sintered particles of tens of micrometers. Accordingly, the manufacturing process is simple and energy-saving.

    Abstract: A device of detecting a door/window status includes a signal generating unit and a signal sensing module. The signal generating unit is disposed beside a door/window to generate a position signal. The signal sensing module is disposed opposite the signal generating unit and includes a three-axis accelerometer, a three-axis magnetic force gauge and a microcontroller. The microcontroller reads the position signal generated from the signal generating unit and detection signals generated from the three-axis accelerometer and the three-axis magnetic force gauge while the door/window is operating to thereby determine the position and status of the door/window, thereby enhancing home safety. A method of detecting the door/window status with the device is further introduced.

    Abstract: A yellow light photolithographic process and an electroplating process are performed multiple times to produce copper plated layers on the aluminum nitride (AlN) substrate. The copper plated layers are plated in sequence into a stack structure with each layer having reduced length. The parameters of the yellow light photolithographic process can be adjusted, such that each copper plated layer is formed horizontally for a predetermined length into a stack structure of step layers tapering off upward, while a predetermined angle is formed by the tangent line passing through edges of the respective step layers, and the surface of the AlN substrate. An adhesion layer, a copper seed layer, a first copper plated layer, a second copper plated layer, a third copper plated layer, and a nickel plated layer are formed in sequence on the AlN substrate, to form a metalized circuit of multi-layer stack.

    Abstract: A quick subpixel absolute positioning device and method are introduced. The method includes the steps of (A) capturing a real-time speckle pattern of a target surface; (B) providing a coarse-precision speckle coordinate pattern and a plurality of fine-precision speckle coordinate patterns, wherein the coarse-precision speckle coordinate pattern and the fine-precision speckle coordinate patterns include a coordinate value; (C) comparing the real-time speckle coordinate pattern with the coarse-precision speckle coordinate pattern by an algorithm and then comparing the real-time speckle coordinate pattern with the fine-precision speckle coordinate patterns to obtain a coordinate value, wherein each said coarse-precision speckle coordinate pattern corresponds to a set of fine-precision speckle coordinate patterns, and the fine-precision speckle coordinate patterns are obtained when the coarse-precision speckle coordinate pattern is captured again and then captured repeatedly according to a fixed fine-precision displacement distance. Accordingly, the subpixel positioning is attained by quick comparison and manifests high precision.
