Abstract: An ammonia-rich combustion coupled dual-mode prechamber ammonia-fueled engine control system is provided, including an ammonia-fueled engine and an electronic control unit. The ammonia-fueled engine includes a combustion chamber, a dual-mode jet ignition device, and an ammonia injector. The dual-mode jet ignition device includes a prechamber, an air injector, and a fuel injector. When the engine operates, ammonia fuel is firstly injected into the combustion chamber by the ammonia injector to form a rich ammonia-air mixture with air in the combustion chamber. During a compression stroke of the engine, the rich ammonia-air mixture in the combustion chamber is entered into the prechamber through a jet hole. The air injector performs scavenging in the prechamber until a equivalence ratio of prechamber gas mixture is less than 1.0, and then the fuel injector injects fuel into the prechamber forming target mixture. Finally, the target mixture is ignited by the spark plug.

Abstract: Methods, systems, and devices for sorting retired blocks of non-volatile memory cells are described. A memory system may recover a block that has been marked as “bad” using a requalification process. For example, after operating in an error protection mode for the block, the memory system may monitor the block to determine whether a status flag indicating an access error is set. If the status flag is set, the memory system may store information that indicates the block is unrecoverable, and the block may subsequently be retired. Alternatively, if a status flag is not set, the memory system may store information that indicates the block may be recoverable. If one or more additional access operations to the block are successful, the memory system may store information that indicates the block may be used for subsequent access operations.

Abstract: In an embodiment, during an overload or short circuit condition, a current limit circuit of an inverter is utilized in a pulse-by-pulse manner, which in turn causes the AC output of the inverter to operate in a hiccup mode (e.g., pulse-by-pulse based on and off dependent upon the output current) and automatically recover once the operating parameters (e.g., output current) are within the proper ranges. The pulse-by-pulse current limit circuit is configured to protect the switching circuits of the inverter from shorting or device failure during any peak operating voltage conditions by ensuring on/off timing accuracy of the inverter.

Abstract: The present disclosure relates to the prioritization of devices taking part in a multi-user random access wireless communication. Based on some known conditions, devices that comply with the conditions are given preferential treatment during the random access period. The preferential treatment may refer to the eligible devices being allowed to access more resource units during the random access, or it may also mean faster access to the medium during the random access. By taking advantage of the methods described in the present disclosure, it is possible to assign higher priority to selected frame types and/or device categories in a multi-user random access wireless communication system.

Abstract: This application discloses a CIS pixel readout structure. An SF and an SG adopt an asymmetric spacer structure, so that the pitch from a lower end of a source metal plug of the SG to SG gate poly can be reduced while keeping the pitch from a lower end of a drain metal plug of the SF to SF gate poly unchanged, thus reducing the pitch from a drain connecting point of the SF to a source connecting point of the SG. Since a source of the SG is not connected with working voltage and it is not influenced by leakage, not only can GIDL current be maintained, but also parasitic resistance can be reduced. Without changing its effective size, it can reduce the parasitic resistance effect while reducing the area of a combined structure of the SF and the SG.

Abstract: This application discloses a CIS pixel readout circuit structure. An SG and an SF adopt different transverse thicknesses of spacers. The spacer of the SG adopts a smaller transverse thickness to reduce the parasitic resistance. The spacer of the SF adopts a larger transverse thickness to reduce the GIDL current. In the CIS pixel readout circuit structure according to this application, drain metal plugs are formed on outer sides of both left and right ends of an SF gate structure. The SF and the SG form a T-shaped combined compact structure to achieve equivalent parallel connection of two SF, thus effectively reducing the parasitic resistance of the share active area between the SG and the SF, and simultaneously saving the space area. This application further discloses a method for fabricating a CIS pixel readout circuit structure.
