Publication number: 20240124494Abstract: Described are multi-resonance-thermally-activated delay-fluorescence compounds containing (i) a polycyclic aromatic/heteroaromatic ligand in which a plurality aromatic/heteroaromatic rings are linked by boron and nitrogen atoms and (ii) an N-heterocyclic carbene ligand, with both ligands coordinated to a metal atom/ion that has a high spin-orbit coupling. The use of the high spin-orbit coupling of metals and/or metal ions facilitates the intersystem crossing and/or reversed intersystem crossing processes of MR-TADF emitters, thereby largely accelerating the rate of TADF and substantially shortening the lifetime of deleterious triplet excitons. The MR-TADF emitters can be used to fabricate blue to green emitting OLEDs.Type: ApplicationFiled: September 13, 2023Publication date: April 18, 2024Inventors: Chi-Ming Che, Siyuan Cai, Tsz-Lung Lam, Gang Cheng

Patent number: 11950807Abstract: A puncturing device and an anchoring device, the puncturing device including: a puncturing needle, an inflatable anchoring balloon, and a catheter which passes through a proximal end and distal end of the anchoring balloon, the puncturing needle being movably accommodated within the catheter; in a filled state, a central area of an end portion of the distal end of the anchoring balloon is depressed towards the proximal end to form a depressed area, and a distal end of the catheter is located within the depressed area. The anchoring device includes the anchoring balloon and the catheter. The puncturing device may improve the accuracy and success rate of puncturing, and after puncturing is complete, an expansion balloon may be transported along a guide wire to expand a puncturing opening by simply withdrawing the puncturing needle and a push rod.Type: GrantFiled: June 17, 2022Date of Patent: April 9, 2024Assignee: LIFETECH SCIENTIFIC (SHENZHEN) CO., LTDInventors: Weiguo Fu, Mingyang Cai, Gang Wang, Xinjiong Qiu

Patent number: 11924178Abstract: Disclosed is a system and a method for information distribution. The system comprises: a server for generating a group key and its corresponding key deriving parameter, wherein the server encrypts sensitive contents by using the group key to obtain encrypted information; and terminals configured to receive the encrypted information through an open channel, extract the group key, then decrypt the encrypted information by using the group key to obtain the original content. In the group forming process, each terminal encrypts its private identifier using the public key and submits the ciphertext to the server. In information distribution process, the server transmits the ciphertext of sensitive contents and the key deriving parameter to the terminals via open channel Because private information available only to respective group members is required for calculating the group key, this mechanism ensures that the sensitive content can be transmitted securely on the open channel.Type: GrantFiled: December 13, 2021Date of Patent: March 5, 2024Assignee: MAXIO Technology (Hangzhou) Co., Ltd.Inventors: Gang Fang, Wei Xu, Yan Cai, Jun Chen, Zhehang Wen, Li Liang, Guohua Chen, Yiming Lu

Publication number: 20180196973Abstract: A security certification method for hiding an ultra-high frequency electronic tag identifier. By encrypting the electronic tag identifier (TID) using a random number, and returning it in the cipher text, this certification method can effectively avoid an illegal reading/writing device from acquiring the TID information and from performing illegal tracking and identity recognition on an object identified by the electronic tag. Meanwhile, this certification method can effectively resist attacks, such as eavesdropping, counterfeiting, replaying, and etc. It has the advantages of preventing the electronic tag information from being eavesdropped and counterfeited, and etc. The security certification method uses the symmetric encryption algorithm of the national commercial cryptographic algorithm and the dual-key and the two-step certification mechanism.Type: ApplicationFiled: May 25, 2015Publication date: July 12, 2018Applicant: TRAFFIC MANAGEMENT RESEARCH INSTITUTE OF THE MINISTRY OF PUBLIC SECURITYInventors: Zhengliang SUN, Jin HUANG, Gang CAI, Dongbo LIU, Jiabin HU
