Patent number: 12243762Abstract: A door locking mechanism and semiconductor container using the same include door panel, cover, and locking module. The door panel has a first stop structure. The cover and the door panel define an accommodating space for receiving the locking module. The locking module includes rotating member, holding member, and elastic member. The elastic member is disposed on the holding member and has a second stop structure near the first stop structure. The elastic member is disposed between the holding and the rotating member. The elastic member is compressed when a force is applied to the holding member, and the second stop structure detaches from a limitation state with the first stop structure for allowing a rotating operation of the rotating member. The elastic member elastically restores when the force is removed, and the second stop structure returns to the limitation state for limiting the rotating operation.Type: GrantFiled: April 12, 2023Date of Patent: March 4, 2025Assignee: Gudeng Precision Industrial Co., LTDInventors: Ming-Chien Chiu, Yung-Chin Pan, Cheng-En Chung, Chih-Ming Lin, Po-Ting Lee, Wei-Chien Liu, Tzu-Ning Huang

Publication number: 20250048334Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, by a first subscription of the UE, a connection to a first network entity using two transmit (Tx) chains of the UE. The UE may receive, by a second subscription of the UE, a paging message from a second network entity. The UE may receive, by the first subscription from the second subscription, a request for the first subscription to enter a mode that supports one Tx chain. The UE, by the first subscription, may reduce the two Tx chains to the one Tx chain for the first subscription. The UE may perform, by the second subscription to the second network entity, the connection setup based at least in part on the first subscription reducing the two Tx chains to the one Tx chain. Numerous other aspects are described.Type: ApplicationFiled: October 18, 2024Publication date: February 6, 2025Inventors: Tom CHIN, Peter Pui Lok ANG, Reza SHAHIDI, Kuo-Chun LEE, Wei-Jei SONG, Arvind Vardarajan SANTHANAM, Rajeev PAL

Publication number: 20250039856Abstract: Aspects are provided which allow a UE including an application processor and a modem to disable measurements of reference signals from 5G base stations which are inapplicable to EN-DC. The UE may receive a reference signal from a base station. The UE may identify a frequency range. The UE may provide, using the application processor, an indication to the modem. The UE may determine whether to measure the reference signal using the modem based on the indication provided to the modem from the application processor and whether the reference signal is within the identified frequency range and further based on whether the base station is standalone or non-standalone. The UE may refrain from measuring the reference signal in response to the determination. As a result, inter-RAT handovers from LTE base stations to 5G base stations are prevented, UE power consumption is thereby saved, and support for EN-DC is maintained.Type: ApplicationFiled: October 16, 2024Publication date: January 30, 2025Inventors: Tom CHIN, Rajeev PAL, Kuo-Chun LEE, Arvind Vardarajan SANTHANAM, Wei-Jei SONG, Abhishek BHATNAGAR, Min WANG
