Publication number: 20240107414Abstract: 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.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Yu-Chieh HUANG, Kuhn-Chang LIN, Jen-Chun CHANG, Wen-Hsin HSIA, Chia-Jou LU, Sheng-Chih WANG, Chenghsin LIN, Yeong Leong CHOO, Chun-Hsiang CHIU, Chihhung HSIEH, Kai-Chun CHENG, Chung Wei LIN

Patent number: 11931187Abstract: A method for predicting clinical severity of a neurological disorder includes steps of: a) identifying, according to a magnetic resonance imaging (MRI) image of a brain, brain image regions each of which contains a respective portion of diffusion index values of a diffusion index, which results from image processing performed on the MRI image; b) for one of the brain image regions, calculating a characteristic parameter based on the respective portion of the diffusion index values; and c) calculating a severity score that represents the clinical severity of the neurological disorder of the brain based on the characteristic parameter of the one of the brain image regions via a prediction model associated with the neurological disorder.Type: GrantFiled: March 16, 2018Date of Patent: March 19, 2024Assignees: Chang Gung Medical Foundation Chang Gung Memorial Hospital at Keelung, Chang Gung Memorial Hospital, Linkou, Chang Gung UniversityInventors: Jiun-Jie Wang, Yi-Hsin Weng, Shu-Hang Ng, Jur-Shan Cheng, Yi-Ming Wu, Yao-Liang Chen, Wey-Yil Lin, Chin-Song Lu, Wen-Chuin Hsu, Chia-Ling Chen, Yi-Chun Chen, Sung-Han Lin, Chih-Chien Tsai

Patent number: 11936418Abstract: A radar signal processing system with a self-interference cancelling function includes an analog front end (AFE) processor, an analog to digital converter (ADC), an adaptive interference canceller (AIC), and a digital to analog converter (DAC). The AFE processor receives an original input signal and generates an analog input signal. The ADC converts the analog input signal to a digital input signal. The AIC generates a digital interference signal digital interference signal by performing an adaptive interference cancellation process according to the digital input signal. The DAC converts the digital interference signal to an analog interference signal. Finally, the analog interference signal is fed back to the AFE and cancelled from the original input signal in the AFE processor while performing the front end process, reducing the interference of the static interference from the leaking of a close-by transmitter during the front end process.Type: GrantFiled: April 27, 2021Date of Patent: March 19, 2024Assignee: KAIKUTEK INC.Inventors: Mike Chun-Hung Wang, Chun-Hsuan Kuo, Mohammad Athar Khalil, Wen-Sheng Cheng, Chen-Lun Lin, Chin-Wei Kuo, Ming Wei Kung, Khoi Duc Le

Patent number: 8065712Abstract: Methods and devices for qualifying a client machine to access a network, based on policies governing required protective measures, such as virus checking and operating system updates, are disclosed. A client machine must pass various checks to qualify for access. A client machine may be redirected to remediation resources that support efforts to bring the client machine into compliance with applicable network access requirements. A policy repository is updated regularly by vendors of protective measures. An administrator establishes user roles that are mapped to policy rule sets retrieved from the policy repository. The policy rule sets govern qualification of client machines for access to the network in accordance with the roles of the users of the machines. An access server is an intermediary between a client machine and the access manager. A client agent runs on the client machine and carries out checks, and reports the results via the access server to the access manager.Type: GrantFiled: May 25, 2005Date of Patent: November 22, 2011Assignee: Cisco Technology, Inc.Inventors: Wen-Chun Cheng, Po-Cheng Wang, Venkatapathi Raju Srirajavatchavai, Rajesh Nair

Patent number: 8005049Abstract: The present invention relates to methods and devices that support mobility of a client across a campus, particularly mobility across VLANs and subnets, while preserving the client's assigned IP address. Both layer 2 and layer 3 packets are supported. Mobility support most clearly applies to wireless clients, but could apply to other kinds of mobile connections, even to wired connections. A smart server is adapted to support multiple VLANs and to modify and redirect packets in sessions with a client that moves from one VLAN to another, preserving the client's assigned EP address. Two or more smart servers, in cooperation with a smart manger, modify packets and tunnel them between smart servers when a client that moves from one VLAN to another and from one smart server to another, again preserving the client's assigned IF address.Type: GrantFiled: April 12, 2010Date of Patent: August 23, 2011Assignee: Cisco Technology, Inc.Inventors: Wen-Chun Cheng, Po-Cheng Wang, Rajesh Nair
