Patent number: 12004181Abstract: A Central Unit-Control Plane (CU-CP) of a radio access network (RAN) node can operate in a communication network to dynamically schedule user-plane (UP) communications. The CU-CP can be communicatively coupled to a Distributed Unit (DU) and a Central Unit-User-Plane (CU-UP) of the RAN node. The CU-CP can provide indication of one or more available UP paths to at least one network element. The at least one network element can include one or more of: a user equipment, UE; the CU-UP of the RAN node; and/or the DU of the RAN node. The CU-CP can provide indication of a scheduling strategy for data transmissions to the at least one network element.Type: GrantFiled: February 13, 2020Date of Patent: June 4, 2024Assignee: Telefonaktiebolagget LM Ericsson (Publ)Inventors: Patrik Karlsson, Paul Stjernholm, Erik Westerberg, Mathias Sintorn, Ulf Eric Andretzky

Publication number: 20190180787Abstract: A method comprises obtaining a playlist that comprises a plurality of audio items. The playlist is divided into a plurality of coherent groups. Each coherent group comprises a respective sequence of audio items of the plurality of audio items with a common attribute. For a respective coherent group of the plurality of coherent groups, a parameter value of a first audio item of the respective sequence is determined, a parameter value of a second audio item of the respective sequence is adjusted based on the determined parameter value of the first audio item, and a transition media item is formed. The transition media item corresponds to a transition between the first and second audio items that are adjacent in the respective sequence. The transition media item is provided to a second electronic device.Type: ApplicationFiled: February 14, 2019Publication date: June 13, 2019Inventors: Tristan JEHAN, Frej CONNOLY, Miles LENNON, Rachel BITTNER, Mateo RANDO, Ulf KARLSSON

Patent number: 6224940Abstract: The present invention relates to a method and device for manufacturing coated sleeves, whereby the sleeve is positioned vertically and held stationary, while a feed pipe is introduced from below, by vertical displacement, concentrically into the sleeve. Also from below, an excess of fluid is supplied under pressure, through the feed pipe. The fluid is allowed to emanate from an upper end outlet of the feed pipe and allowed to flow by gravity in the small gap which is formed between the feed pipe and the internal walls of the sleeve. The internal walls of the sleeve are thereby coated with the fluid, while at the same time, the coating of the outside of the sleeve is prevented. The invention also relates to a writing pen comprising a coated sleeve.Type: GrantFiled: April 22, 1999Date of Patent: May 1, 2001Assignee: ULF KarlssonInventors: Ulf Karlsson, Sören Sjöholm
