  • Publication number: 20220147113
    Abstract: A hinge assembly, including a rotating shaft and a pair of cams, is provided. The cams are sleeved on the rotating shaft so as to be rotatable relative to each other. The pair of cams respectively has a first flat surface and a second flat surface facing each other, and a curved surface adjacent to the first flat surface and the second flat surface. The first flat surface of one of the cams passes by the curved surface to move from one flat surface to the other flat surface of the other cam, so as to enable the pair of cams to move relatively away or closer along an axial direction of the rotating shaft. The curved surfaces of the cams are in surface contact when the first flat surface passes by the curved surface. A portable electronic device is also provided.

  • Patent number: 7867453
    Abstract: The present invention relates to a gravity-driven fraction separator and method thereof. The gravity-driven fraction separator is substantially a substrate having a microchannel structure arranged thereon, in which the microchannel structure is extending longitudinally on the substrate while sloping with respect to the level of the substrate by a specific angle. As a micro fluidics is being filled in a loading well situated upstream of the microchannel structure, the micro fluidics is driven by gravity to flow downstream in the microchannel structure while filling a plurality of manifolds formed in a area situated downstream of the microchannel structure, so that accurate quantification and separation of the micro fluidics using the plural manifolds, each having a specific length, can be achieved and provided for posterior inspection and analysis.

  • Publication number: 20100308449
    Abstract: A manufacturing method of semiconductor package is provided. A carrier is provided. The chips are disposed on the carrier. The chips are encapsulated by a molding compound, so that the molding compound and the chips form a chip-redistribution encapsulant. The carrier is removed, so that the chip-redistribution encapsulant exposes the pads of the chips. The plasma is applied on the pads and the molding compound. A first dielectric layer is formed on the pads and the surface of the molding compound. The plasma is applied on a surface of the first dielectric layer. A patterned conductive layer is formed on the surface of the first dielectric layer. A second dielectric layer is formed on the patterned conductive layer and the first dielectric layer. A plurality of solder balls are formed on the second dielectric layer. The chip-redistribution encapsulant is divided so as to form a plurality of packages.

  • Patent number: 7713485
    Abstract: A microfluidics switch with moving planes has a first substrate with some holes and a second substrate with some micro-channels. Herein, the relative planes of both substrates are covered by a hydrophobic material. Therefore, while the substrates are neighboring and relatively moving, the overlap relation between the holes and the micro-channels are varied and a switch function is provided. Further, by using the hydrophobic material, while the distance between substrates is smaller than the height of drop of each liquid inputted into the holes, the fluids can not fluid between the planes and then different micro-channels are isolated from each other.

  • Publication number: 20090053106
    Abstract: The present invention relates to an autonomous microfluidic apparatus. The autonomous microfluidic apparatus is substantially a substrate having a microchannel structure arranged thereon. As a microfluid is being filled in a loading well situated upstream of the microchannel structure, the microfluid is affected by interactions between gravity, adhesive force and surface tension and thus driven to flow downstream in the microchannel structure while filling a plurality of manifolds formed in a area situated downstream of the microchannel structure, so that accurate and autonomous quantification and separation of the microfluid using the plural manifolds, each having a specific length, can be achieved and provided for biomedical inspection and analysis.

  • Publication number: 20070128082
    Abstract: The present invention provides a microflow coverage ratio control device, which comprises two reservoirs, at least one communication channel, a flow driver and two external tubes. The present invention utilizes liquid-level gravities of fluids in the two reservoirs to drive the fluids simultaneously flowing into a reaction chamber to form different fluid coverage ratios in the reaction chamber. The present invention employs the flow driver associated with the communication channel to change the liquid levels of the fluids in the two reservoirs, thereby changing the fluid coverage ratios in the reaction chamber. According to the potential energy conservation, the fluid pressure of the reaction chamber is kept constant during the change of the fluid coverage ratios. The interference of the reaction chamber is eliminated.
