  • Patent number: 11123062
    Abstract: The technical problem to be solved by the present invention is to design a cosmetic surgical method for presenting a deeper or longer philtrum at the lip by adjusting the muscle flaps at the lips and nose. The theoretical basis of this surgical method is a “theory of labionasal muscle tension thread group” summarized from a series of studies with respect to anatomy, biomechanics and clinical surgical verification. According to this theory, the labionasal muscle tension structure is reconstructed by surgical adjustment of the position and direction of the muscle flaps, so as to produce an effect of changing the profile of the “philtrum” and to improve or remodel the “philtrum” as an aesthetic labial structure.

  • Patent number: 8874167
    Abstract: A communication device comprises a single radio resource unit that is shared by a plurality of virtual modems (VMs), each uniquely associated with a single one of a plurality of SIM cards. Traffic related to the SIM cards are concurrently handled utilizing corresponding VMs. Available radio resource in the single radio resource unit are shared by the VMs based on corresponding VM states, namely, an active state, an idle state and a suspended state. VMs in an idle state concurrently monitor paging events and concurrently perform idle mode procedures such as location updating. VMs not related to an intended traffic are suspended. A VM related to the intended traffic is transitioned from an idle state to an active state to enable the communication for the intended traffic. Once the communication is complete, the suspended VMs are resumed to continue idle mode activities.

  • Publication number: 20140295831
    Abstract: A wireless communication device includes a single baseband processor and RF chain for servicing a first and second SIM. Each of the SIMs connects to a different network, and one may be used for one data type while the other is used for another data type. In order to track the connectivity of an inactive first SIM, a controller periodically interrupts service to the second SIM. During its connection, the first SIM monitors the connection to its network. A triggering mechanism and trigger threshold define when a switch to a new cell is needed. The device receives the mechanism and threshold from the network and calculates a modified threshold and/or mechanism is order to reduce a number of potentially missed calls.
