  • Patent number: 12659824
    Abstract: A method performed by a user equipment, UE, includes obtaining a maximum timing advance (TA) for wireless communications to apply for a serving base station, BS, switching in a high speed train (HST) network. The method includes updating the TA for wireless communications according to TA commands as the UE proceeds along a track in the HST network. The method includes determining that the BS panel serving the UE has switched to a new BS panel along the track. The method includes responsive to determining that the BS panel serving the UE has switched to the new BS panel, setting the TA to a minimum TA for wireless communication or to the maximum TA for wireless communications based on a direction of travel of the HST with respect to the new BS panel.

  • Publication number: 20260160261
    Abstract: A centrifugal fluid pump includes a seal device that is located in the pump running clearance gap in the vicinity of the pump inlet. The seal device reduces the amount of the recirculation flow typically present in this clearance gap. The seal device has a static contact with the pump inlet lip and a dynamic contact with a feature on the impeller shroud. The seal device contact force can either be established using the local pressure differential across the seal device or by a mechanical spring.

  • Publication number: 20260101214
    Abstract: Methods and systems are described for AI and/or ML model selection in a telecommunications network. One example embodiment includes obtaining a first set of one or more criteria for selecting between at least two AI/ML models; performing at least one measurement procedure to obtain one or more measurements; and using the obtained one or more measurements and the first set of one or more criteria to select between the at least two AI/ML models. A measurement procedure can comprise e.g. CSI, radio link procedure (RLP), positioning measurement, measurement related to cell change procedure etc. Certain described embodiments enhance measurement performance of the measurement (e.g., CQI) and correspondingly improve the outcome/performance of the procedure (e.g., data scheduling) using the measurement. This in turn reduces the overall processing in the UE, frees up at least part of the memory resources and reduces the UE power consumption.

  • Publication number: 20250314314
    Abstract: A rotary disc valve includes a valve housing having multiple ports. The valve housing includes a valve body and a lid that together define a valve chamber. The valve housing includes chamber walls that segregate the chamber into subchambers that provide a portion of a fluid path through the valve housing and are connected to valve ports. A first subset of the subchambers is disposed along a first circle, a second subset of the subchambers is disposed along a second circle, and the first and second circles surround the rotational axis. Each of the first set of subchambers is fluidly connected to a corresponding valve port via a corresponding fluid passageway, each fluid passageway extending linearly and non-radially. Each of the second set of subchambers adjoins the sidewall and is directly fluidly connected to a corresponding valve port, whereby fluid exits the second set of subchambers in a radial direction.
