  • Publication number: 20240147405
    Abstract: A controlling method for a wireless communication device is provided. The controlling method for the wireless communication device includes: attaching a first Universal Subscriber Identity Module (USIM) to a Long-Term Evolution (LTE) network; determining whether a second USIM is camped on the LTE network; detecting whether a paging collision is happened, if the second USIM is camped on the LTE network; generating a requested International Mobile Subscriber Identity (IMSI) offset for the second USIM, if the paging collision is happened, wherein the requested IMSI offset is 1 or min(T, nB)?1, T is a default paging period and nB is a number of paging occurrences within the default paging period; transmitting an attach request with the requested IMSI offset to the LTE network for the second USIM; receiving a negotiated IMSI offset from the LTE network; and attaching the second USIM to the LTE network with the negotiated IMSI offset.

  • Patent number: 10894870
    Abstract: Methods of recovery of pristine polymers and hydrocarbon mixtures from a sorted waste feedstock or mixtures of waste feedstock, which are with or without organic additives are disclosed. The methods include Sequential Selective Extraction and Adsorption (SSEA), Hydrothermal Processing (HTP), and a combination of SSEA and HTP. Exemplarily, SSEA includes selecting a first solvent (S1), inputting the S1 and a sorted feedstock free of organic additives into an extractor, heating, waiting, and separating insolubles forming a pristine polymer solution. Exemplarily, HTP includes inputting a hydrothermal solvent and a sorted feedstock free of organic additives into a reactor, heating to form subcritical or supercritical H2O, waiting, causing thermal depolymerization to produce a slurry, cooling, venting formed gases and separating the hydrocarbon mixture.

  • Patent number: 9754898
    Abstract: A semiconductor package is provided, which includes: a carrier; at least an interposer disposed on the carrier; an encapsulant formed on the carrier for encapsulating the interposer while exposing a top surface of the interposer; a redistribution layer formed on the encapsulant and the top surface of the interposer; and at least a semiconductor element disposed on the redistribution layer. The top surface of the interposer is flush with a surface of the encapsulant so as for the redistribution layer to have a planar surface for disposing the semiconductor element, thereby preventing warpage of the interposer and improving the reliability of electrical connection between the redistribution layer and the semiconductor element.
