Abstract: A package includes a frontside redistribution layer (RDL) structure, a semiconductor die on the frontside RDL structure, and a backside RDL structure on the semiconductor die including a first RDL, and a backside connector extending from a distal side of the first RDL and including a tapered portion having a width that decreases in a direction away from the first RDL, wherein the tapered portion includes a contact surface at an end of the tapered portion. A method of forming the package may include forming the backside redistribution layer (RDL) structure, attaching a semiconductor die to the backside RDL structure, forming an encapsulation layer around the semiconductor die on the backside RDL structure, and forming a frontside RDL structure on the semiconductor die and the encapsulation layer.

Abstract: A package structure including a semiconductor die, a redistribution circuit structure and an electronic device is provided. The semiconductor die is laterally encapsulated by an insulating encapsulation. The redistribution circuit structure is disposed on the semiconductor die and the insulating encapsulation. The redistribution circuit structure includes a colored dielectric layer, inter-dielectric layers and redistribution conductive layers embedded in the inter-dielectric layers. The electronic device is disposed over the colored dielectric layer and electrically connected to the redistribution circuit structure.

Abstract: The present disclosure provides a method for manufacturing an auto-crosslinked hyaluronic acid gel, comprising conducting auto-crosslinking reaction of a colloid containing hyaluronic acid continuously at low temperature in an acidic environment, and treating the reaction product with steam at high temperature to obtain the auto-crosslinked hyaluronic acid gel with high viscosity.

Abstract: A wind power generation apparatus includes a rotating shaft, a wind power generation device assembled to the rotating shaft, and an acceleration restriction mechanism. The wind power generation device includes a drag blade fixed on the rotating shaft, an inner housing connected to an outer edge of the drag blade, and an outer housing sleeved around the inner housing. The acceleration restriction mechanism includes a plurality of swing arms pivotally connected to the inner housing and a metal ring fixed on the outer housing. A magnetic portion of each swing arm is movable relative to the inner housing from an initial position to an acceleration restriction position. When the magnetic portion of each swing arm is at the acceleration restriction position, the magnetic portion at least partially covers the metal ring, so that the metal ring generates an eddy current limiting a rotating acceleration of the drag blade.

Abstract: An optical volume measurement device includes a main body, a pair of photographic lenses, an optical distance measuring unit and an optical projecting unit. The photographic lenses are disposed on the main body. Each of the photographic lenses has an image acquiring area extended forwardly therefrom and captures images within the image acquiring area separately, and a resolution distance range is formed in front of each photographic lens. Each photographic lens identifies the image within the resolution distance range, and image acquiring areas are overlapped to form a measurement area within the resolution distance range. The optical projecting unit is disposed on the main body and forwardly project an optical alignment indicator in a projection area. The projection area is located in the measurement area within the resolution distance range.

Abstract: A novel vertical-axis wind turbine (VAWT) is provided. The VAWT has rotor to help starting up and avoiding overspeed. Blades of the VAWT are used for an auxiliary mechanism. By adjusting rigidity of multiple springs with torque of support blades, the blades forms equilibrium of rotating status under different wind speeds. The present disclosure makes the VAWT device more effective for improving efficiency as well as reducing cost while increase in spatiality of the VAWT is avoided.
