  • Publication number: 20250079984
    Abstract: A conversion control circuit controls plural stackable sub-converters which are coupled in parallel to generate an output power to a load. The conversion control circuit includes a current sharing terminal and a current sharing circuit. A current sharing signal is connected, in parallel, to the current sharing terminals. The current sharing circuit includes: configuration (1): the current sharing signal is generated only according to an inductor current corresponding to one of plural inductors of the plural stackable sub-converters; or configuration (2): the current sharing signal is generated according to plural inductor currents corresponding to plural inductors of plural activated phases of the plural stackable sub-converters, wherein a ratio of a portion of the current sharing signal generated by a master control circuit to a portion generated by one of the slave control circuits is k which relates to a difference between a total phase number and an activated phase number.

  • Publication number: 20250071730
    Abstract: Network nodes, such as distributed units (DUs) and central units (CUs) of distributed base stations, perform methods for managing paging operations. An example method, performed by a DU. for determining paging occasions includes: receiving (1102), by the DU from the CU, an indication as to whether a user equipment (UE) operating in an inactive state associated with a protocol for controlling radio resources supports determining inactive state paging occasions using a parameter defined for determining idle state paging occasions; determining (1104), by the DU, the inactive state paging occasions based on the indication; and paging (1106), by the DU, the UE operating in the inactive state at the inactive state paging occasions.

  • Publication number: 20250071845
    Abstract: A base station capable of resuming a suspended radio connection between a user device (UE) and a radio access network (RAN) receives a request to resume the suspended radio connection for the UE operating in dual connectivity (DC) with a first master node (MN) and a first secondary node (SN) (602), causes a previous configuration related to at least one of the first MN and the first SN to be released (604), and transmits, to the UE while in the inactive state, a command to resume the suspended radio connection, the command including new configuration related to at least one of the first MN, a second MN, the first SN, or a second SN (606).

  • Publication number: 20250063457
    Abstract: A method and system for managing candidate cell configuration for a user equipment (UE) initially in communication with at least a first node is disclosed herein. The method is implemented in a second node and comprises receiving, by the second node and from the first node, a request for connectivity with the second node, the request including at least a procedure indicator; and transmitting, by the second node to the first node and depending on the procedure indicator, one of a list of two or more conditional configurations or a single conditional configuration, the list of two or more conditional configurations or the single conditional configuration to be used by the UE.

  • Publication number: 20230407105
    Abstract: The present invention provides a water-based heavy-duty anti-corrosion coating structure and manufacturing method thereof. The structure includes a base material and a water-based coating. The base material includes a surface. A water-based coating material is sprayed on the surface of the base material to form the water-based coating. The water-based coating material includes a water-based polymer resin, a film-forming auxiliary, an auxiliary, a water-based color paste, and a deionized water. Therein, by weight percentage, the coating material comprises 40% to 60% of water-based polymer resin, 10% to 20% of film-forming auxiliary, 1% to 2% of auxiliary, 5% to 16% of water-based color paste, and 20% to 40% of deionized water. Therefore, the volatile organic compounds (VOC) content of the coating material is effectively reduced, and an excellent anti-corrosion property is provided.

  • Publication number: 20130329292
    Abstract: A lens mechanism and a device using the same are provided. The lens mechanism has an optical axis and comprises a zoom module, a focus module and a focusing lens group. The zoom module performs an optical compensation. The focus module comprises a rotatable arm. The focusing lens group is disposed on the rotatable arm, wherein when the lens mechanism is in a stand-by state, the focusing lens group is located at the optical axis; when the lens mechanism is in a close-end, the focusing lens group is away from the optical axis.

  • Patent number: 8314997
    Abstract: A zoom lens barrel includes a fixed barrel, a guide barrel received in the fixed barrel, a cam barrel received in the fixed barrel and housing the guide barrel, a zoom barrel sandwiched between the guide barrel and the cam barrel, and a lens cover covering on the zoom barrel. The cam barrel includes a flange radially formed on an end close to the lens cover. The zoom barrel includes a ring portion protruding out from an end close to the fixed barrel. A step surface is formed between the outer side surface of the zoom barrel and that of the ring portion. When the zoom lens barrel is in an unfolded state, the step surface interferingly resists against a bottom surface of the flange, to limit an axial movement between the cam barrel and the zoom barrel.
