Publication number: 20240259779Abstract: A user equipment (UE) device performs fast network camping when multiple SIMs of the UE device are out of service. A first software stack begins scanning for available networks and finds an available network at a frequency X. The first software stack decodes system information received from the available network at frequency X and determines that the available network is mapped to the SIM associated with a second software stack of the UE device. The first software stack signals the second software stack that an available network is mapped to the SIM associated with the second software stack at frequency X. In response to receiving the signal, the second software stack sends an attach request to the available network and completes a network attach procedure.Type: ApplicationFiled: December 20, 2022Publication date: August 1, 2024Inventors: Edison Chen, Shih-Che Chou, Chih-Cheng Wang, Hsueh-Feng Hsieh

Patent number: 11225433Abstract: A sintered machinable glass-ceramic is provided. The machinable glass-ceramic is formed by mixing phyllosilicate material having a sheet structure, with a glass fit and firing the mixture at relatively low temperatures to sinter the phyllosilicate, while maintaining the sheet-like morphology of the phyllosilicate and its associated cleaving properties. The sintered machinable glass-ceramic can be machined with conventional metal working tools and includes the electrical properties of the phyllosilicate. Producing the sintered machinable glass-ceramic does not require the relatively high-temperature bulk nucleation and crystallization needed to form sheet phyllosilicate phases in situ.Type: GrantFiled: December 2, 2016Date of Patent: January 18, 2022Assignee: Ferro CorporationInventors: Srinivasan Sridharan, George E.
