  • Publication number: 20240107414
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

  • Publication number: 20190000021
    Abstract: The rainmaking device includes a first pipe member, a connection member, and a second pipe member. The first pipe member is installed adjacent to a warm water source. The first pipe member has an intake facing the warm water source. A number of blowers configured around the intake. The connection member is connected between the first and second pipe members. The second pipe member has a cone shape whose aperture gradually decreases upward. Through the blowers, the first and second pipe members, wet air above the warm water source of 22-25 degrees is drawn up to a high altitude. Tiny ice crystals attract surrounding water vapor and become larger and heavier. They will then drop as rain when the buoyance can no longer support them. The latent heat released would power the convection of surrounding air so that a chain reaction may be triggered, and cumulonimbus would become rain and fall.

  • Publication number: 20150204008
    Abstract: A manufacturing method of a colored high-strength fiber has a preparation step, a dyeing step and a post-processing step. In the preparation step: a high-strength fiber substrate is surface-treated by solvent, and a surface of the high-strength fiber substrate is fractured, such that a surface-treated substrate is manufactured. In the dyeing step: the surface-treated substrate is plated, wherein multiple metal ions are combined with a surface of the surface-treated substrate, such that a dyed substrate is manufactured. In the post-processing step: the dyed substrate is surface-cleaned to remove remaining agents caused by the dyeing step, such that the colored high-strength fiber is manufactured.

  • Patent number: 8096252
    Abstract: A ship hull structure includes a main hull and a movable rearbody having an engine and a propeller. The movable rearbody is located at a lower side of a stern of the main hull, connected with an aft of the main hull to form an integral unit by a hinge linking device allowing the rearbody to pivot up and down. By a block, a crane or a winch and through a chain or a hanging wire, a pivoting angle of the movable rearbody with respect to the main hull can be adjusted and controlled. A bottom of the hull can be provided with at least one, usually plural, air cushion recess, which is filled with pressurized air to reduce a viscous force between a bottom of the ship and water.

  • Publication number: 20060061002
    Abstract: A method for making a wood-like plate by using a mold structure comprises the steps of pushing a wood texture layer into the mold opening of the slit to enclosing the material feeding mold seat; guiding foaming material into the feeding opening of the material feeding mold seat; and forwarding the wood texture layer to encloses the shaped foam plate tightly adhered on the wood texture layer. By the expanding force of the foaming material, the wood texture layer will resist against the inner surface of the slit in an inner section of the material receiving mold seat since the length of the material feeding mold seat is shorter than the material receiving mold seat. The material is foamed as a wood-like plate along the shaping channel and then enclosed by the wood texture layer as a wood like plate. A device for processing the method is also enclosed.
