  • Publication number: 20240132246
    Abstract: A carton with a detachable buffer plate set includes a bottom plate, two long side plates, an upper cover, two short side plates, two reinforcing side plates, and a detachable buffer plate set. The long side plates and the short side plates are connected to the bottom plate. The upper cover is connected to one of the long side plates. The two reinforcing side plates are connected to the two short side plates respectively. The detachable buffer plate set is detachably connected to one of the reinforcing side plates. Accordingly, by detaching the detachable buffer plate set for supporting and buffering, products of similar size or products with accessories of different sizes may use the same-sized cartons and paper-plastic boxes, so that extra die-cutting costs and storage costs are avoided.

  • 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: 20230221551
    Abstract: A light guide substrate, including a light coupling-in region with multiple first gratings, a light expansion region with multiple sub light expansion regions, and a light coupling-out region, is provided. Each sub light expansion region includes multiple second gratings. The sub light expansion regions include a first set of sub light expansion regions and a second set of sub light expansion regions. Each second grating in the first set of sub light expansion regions includes a first microstructure and a second microstructure. The light coupling-out region includes multiple third gratings. When an image light enters the light guide substrate from the light coupling-in region through the first gratings, the image light is first transmitted to the light expansion region in the light guide substrate, then transmitted to the light coupling-out region through the second gratings, and then emitted from the light coupling-out region through the third gratings.

  • Patent number: 10417080
    Abstract: A remote client screen shots monitoring system for monitoring at least one client includes a preboot execute environment (PXE) module, a terminal multiplexing module, and a monitoring module. The PXE module controls the client to boot up. The client executes operations after booting us and generating screen shots in the process. The monitoring module obtains the screen shots from each client, converts each obtained screen shot to one file, and analyzes each converted file against certain predetermined words which may indicate a fault. The terminal multiplexing module places each generated screen shot together with those of other monitored clients in a display. The monitoring module can accordingly determine whether a fault exists in any one client. A remote client screen shots monitoring method is also provided.

  • Patent number: 9270317
    Abstract: A chip card ejecting mechanism includes a main body, a tray assembled in the main body and configured to receive a chip card, and a door. The door includes a rotating end rotatably mounted on the main body and a push pole protruding from the rotating end.

  • Publication number: 20080075456
    Abstract: A portable electronic device (400) includes a housing (402) and a digital camera module (200). The housing has at least one arcuate housing surface section (4024) at one end thereof. The digital camera module is received in the housing proximate the one end thereof. The digital camera module includes at least one contact portion. Each contact portion has an arcuate contact surface (6400), and each such contact portion tightly engages a corresponding arcuate housing surface section. Owing to the tight engagement of such arcuate surfaces, the top surface of the digital camera module may fit closely against the housing so as to more fully use the space in the portable electronic device. This would help satisfy the miniaturization requirement of the portable electronic device.
