  • Publication number: 20240121679
    Abstract: Improved techniques for selecting a handover target cell are described herein, for example in connection with a 5G disaggregated radio network. For example, in addition to evaluating signal quality metrics that are reported by the user equipment subject to the handover, the disclosed techniques can also evaluate additional metrics. For example, a load associated with potential target cells can be considered as neighbor load can cause handover issues. As another example, a history of success rates associated with a handover to the target cell and/or from the serving cell can be considered as well since handover failures can sometimes result due to issues that can be surfaced by the success rate history.

  • Publication number: 20230117401
    Abstract: Spent catalyst (500) is removed from process microchannels (310) of a Fischer-Tropsch reactor by directing a jet of air (4) from an air knife (1) through slots of a protecting member (2). The air knife is traversed across successive rows of process microchannels (310) in direction A. The spacer member (2) protects an internal microchannel architecture (315) of the process microchannels against damage by the air jet (4) which may approach or exceed sonic velocity as it is directed into the process microchannels.

  • Patent number: 9134079
    Abstract: The invention provides apparatuses and techniques for controlling flow between a manifold and two or more connecting microchannels. Flow between plural connecting microchannels, that share a common manifold, can be made more uniform by the use of flow straighteners and distributors that equalize flow in connecting channels. Alternatively, flow can be made more uniform by sections of narrowed diameter within the channels. Methods of making apparatus and methods of conducting unit operations in connecting channels are also described.
