  • Patent number: 10341971
    Abstract: Provided are a method and an apparatus for transmitting a maximum stratum level in a wireless communication system. An evolved NodeB (eNB) or a home eNB (HeNB) having a global positioning system (GPS) constitutes a maximum stratum level indicating a maximum value of a hop capable of supporting radio interface based synchronization (RIBS) and transmits the constituted maximum stratum level to a small cell. Meanwhile, the small cell determines whether a stratum level is greater than the maximum stratum level, and transmits the maximum stratum level to the eNB or the HeNB having the GPS when the stratum level is greater than the maximum stratum level.

  • Patent number: 10341413
    Abstract: Provided are a method and system for synchronizing a robot with a server. The service sends a time service command including a current time of the server to the robot, and the robot receives the time service command, so as to enable time synchronization of the robot with the server. A control device receives first command data carrying a first timestamp sent from the server, and then determines whether the first timestamp in the first command data has expired. If the first timestamp has expired, the control device receives command data resent from the server until second command data carrying an unexpired second timestamp is received. Finally, the control device controls the robot to execute a corresponding action at a time corresponding to the second timestamp based on the second command data, so as to realize the synchronization of the robot with the command data sent from the server.

  • Publication number: 20190194212
    Abstract: The invention relates to new compounds that reduce c-Myc expression and useful for cancer treatment, particularly hematological cancers such as aggressive B- and T-cell lymphomas. The new compounds may be combined with adjunct c-Myc inhibor agents such as a PI3K inhibitor, CK-1 inhibitor, Akt-inhibitor, proteasome inhibitor and/or mTor inhibitor. The c-Myc reducing agent may be provided as a lead-in treatment to reduce or initiate reduction of c-Myc prior to adminstration of the adjunct cancer therapeutic agent. Treatment with a c-Myc reducing agent modulates the disease state of the c-Myc overexpressing cancer making it less malignant and more susceptible to adjunctive cancer therapies.
