  • Publication number: 20220322287
    Abstract: Provided is a method for transmitting paging information in a cellular system. An object of the method is transmitting paging information which can improve applicability of a limited radio resource by variably and flexibly setting up and mapping a transport channel and a physical channel in order to transmit information notifying start of downlink information from a base station to a terminal in a cellular system for packet transmission. The method includes the steps of: forming a paging channel (PCH) in a transport channel corresponding to generation of paging information; setting a paging indication channel (PICH) based on the paging information and forming the paging indication channel in a radio resource of a physical layer; and allocating the paging channel to the radio resource of the physical layer.

  • Publication number: 20220298008
    Abstract: In one example, an electronic device includes a semiconductor sensor device having a cavity extending partially inward from one surface to provide a diaphragm adjacent an opposite surface. A barrier is disposed adjacent to the one surface and extends across the cavity, the barrier has membrane with a barrier body and first barrier strands bounded by the barrier body to define first through-holes. The electronic device further comprises one or more of a protrusion pattern disposed adjacent to the barrier structure, which can include a plurality of protrusion portions separated by a plurality of recess portions; one or more conformal membrane layers disposed over the first barrier strands; or second barrier strands disposed on and at least partially overlapping the first barrier strands. The second barrier strands define second through-holes laterally offset from the first through-holes. Other examples and related methods are also disclosed herein.

  • Publication number: 20220294004
    Abstract: Disclosed are a method of manufacturing a composite anode for a lithium ion battery and a composite anode for a lithium ion battery manufactured thereby. According to the method provide herein, since a metal catalyst precursor is reduced using Joule heating to obtain a carbon-metal catalyst composite layer, composite anode for a lithium ion battery having a large area in a short period of time can be provided, which is excellent in terms of economic feasibility. Further, since it is possible to manufacture a composite anode for a lithium ion battery with the improved lithium electrodeposition density and reversibility of lithium ions, a composite anode for a lithium ion battery having high capacity and improved life stability can be obtained.

  • Patent number: 11372548
    Abstract: Some systems compress data utilized by a user mode software without the user mode software being aware of any compression taking place. To maintain that illusion, such systems prevent user mode software from being aware of and/or accessing the underlying compressed states of the data. While such an approach protects proprietary compression techniques used in such systems from being deciphered, such restrictions limit the ability of user mode software to use the underlying compressed forms of the data in new ways. Disclosed herein are various techniques for allowing user-mode software to access the underlying compressed states of data either directly or indirectly. Such techniques can be used, for example, to allow various user-mode software on a single system or on multiple systems to exchange data in the underlying compression format of the system(s) even when the user mode software is unable to decipher the compression format.
