  • Publication number: 20250120306
    Abstract: Provided are a triarylamine compound and an organic electroluminescent device thereof, which specifically relate to the field of organic electroluminescent materials. The triarylamine compound has high hole mobility, good thermal stability and great film formability, and when applied to the hole transport layer of an organic electroluminescent device, can reduce the energy potential barrier in a hole injection process, improve hole injection efficiency so that the hole transport rate is balanced with electron transport, increase the recombination probability of excitons in a light-emitting layer, and achieve the maximum recombination of carriers, thereby improving the luminescence efficiency of the device and extending the lifetime of the device. Therefore, the compound has great application and commercial values in the application of OLED devices and possesses a good industrialization prospect.

  • Publication number: 20240179621
    Abstract: In a network comprising a plurality of macro base stations, a plurality of micro base stations and a plurality of user devices (UEs), a method of establishing a wireless communication network includes: assigning the micro base stations into a plurality of clusters and selecting a micro base station from each of the clusters as a cluster head; receiving, from cluster heads of the clusters by the network device, information about candidate sub-clusters determined by UEs, each of the candidate sub-clusters comprises micro base stations whose signal power received at a UE exceeds a pre-defined threshold; identifying at least two schemes of grouping the micro base stations into non-overlapping sub-clusters based on the candidate sub-clusters; for a scheme of the at least two schemes, making each of the UEs select to access a macro base station or to be associated with one of the non-overlapping sub-clusters of the scheme base on respective measurements of signals received from at least one of a macro base station

  • Publication number: 20240155356
    Abstract: Disclosed are a resolution method for intent-based wireless network resource conflicts and an apparatus thereof. The method includes the following steps: periodically acquiring configured resource information about a current wireless network; pre-allocating resources required for a newly-added intent; and determining whether a pre-allocated resource configuration policy is incompatible with a resource configuration policy being executed in a current network. The apparatus includes: an interface module; a solution module; a feedback module; and a storage module. Through the relative priority of intent requirements, a bias of an implementation satisfaction degree of a network configuration policy is determined, and network resource conflicts of intent requirements with different priorities are solved.

  • Patent number: 9383829
    Abstract: A hand-held combination key apparatus configured to input information to an intelligent electronic apparatus is provided. Three to five key groups, which correspond to each corresponding finger of a single hand respectively, are set on one of left side and right side of a shell, each key group having two combination keys, and each combination key being the key with compound functions of touch conduction and press conduction. Various combination states of touch conduction of each combination key are used to search and pre-display characters or operational function symbols; and press conduction of each combination key is used to determine character input or operational function input. The hand-held combination key apparatus can be used in any state without limitation absolutely, such as when the user is sitting, standing, lying down and moving, other than the normal standard keyboard which needs a practicable plane to support in use, saving space.
