Abstract: A vapor chamber heatsink assembly, under vacuum, having a working fluid therein, comprising a plurality of heatsink fins and a vapor chamber is provided. The vapor chamber comprises an upper and lower casing having an upper and lower chamber surface, respectively. The upper and lower chamber surfaces define a plurality of obstructers forming a plurality of braided channels therearound. When heat from a greater temperature heat source and a lower temperature heat source is applied to respective contact surfaces of the lower casing, via the plurality of obstructers and braided channels, respectively, the working fluid and liquid vapor slugs/bubbles travel therethrough, providing an effective phase change mechanism to the greater temperature heat source, while concurrently, hindering agglomeration of working fluid thereto. An effective phase change mechanism is also concurrently provided to the lower temperature heat source due to the non-agglomeration of working fluid to the greater temperature heat source.

Abstract: A MEMS device and a method of manufacturing the same are provided. A semiconductor device includes a substrate; and a membrane over the substrate and configured to generate charges in response to an acoustic wave, the membrane being in a polygonal shape including vertices. The membrane includes a via pattern includes: first lines that partition the membrane into slices and extend to the vertices of the membrane such that the slices are separated from each other near an anchored region of the membrane and connected to each other around a central region; and second lines extending from the anchored region of the membrane toward the central region of the membrane, each of the first lines or each of the second lines including non-straight lines.

Abstract: A wireless charging apparatus with an embedded function is embedded in a power supply socket to wirelessly charge an electronic device. The wireless charging apparatus includes a case, a charging module, and a wireless charging assembly. The wireless charging apparatus includes a power conversion circuit, a communication module, and a controller. The controller realizes a demand voltage of the electronic device according to a handshaking signal to control the power conversion circuit to adjust an output voltage to meet the demand voltage.
