Patent number: 12024021Abstract: A motor vehicle with a scalable frame that may be used with an internal combustion engine or with an electric drive. The vehicle has at least four wheels and a frame with a central support bounded by a front transverse section, a rear transverse section and two longitudinal side profiles. The front and rear transverse sections are formed of cast metal with mechanical connector parts attached respectively to a front frame structure and a rear frame structure. The front transverse section includes cooling duct connector parts adapted to be connected to cooling fluid ducts and electrical connector parts adapted to be connected to conductors of an electric motor, the rear transverse section including electrical connector parts adapted to be connected to an electrical connector, such as a charging terminal.Type: GrantFiled: November 18, 2021Date of Patent: July 2, 2024Assignee: Volvo Car CorporationInventors: Klas Persson, Martin Kristensson

Publication number: 20090257378Abstract: A real-time media session is established between user equipment and a media communication server via a serving access network. According to the Invention, dummy data (e.g. a dummy message) is sent in order to maintain a dedicated channel during the inactive periods of a real-time media session or to trigger an early setup of a dedicated channel in the access network. In this manner, user equipment logged on to a real-time media (e.g. PoC) session are prevented from going to a radio resource idle state, thus avoiding potential long extra delays during real-time media (e.g. PoC) service usage. The invention further allows the sending and receiving user equipment to set up dedicated channels (DCH) already during the start-to-talk procedure of the transmitting user equipment, which in turn potentially reduces end-to-end delays during the conversation.Type: ApplicationFiled: June 22, 2009Publication date: October 15, 2009Applicant: Nokia CorporationInventors: Renaud CUNY, Harri HOLMA, Martin KRISTENSSON

Patent number: 7489903Abstract: The objective of the present invention is to provide means for exchanging usage information in the multioperator mobile networks. Despite the high amount of different reporting alternatives of the present invention, they are not contradicting each other but are only options for different needs. Also the purpose of the present invention is to provide a fair and easy solution to monitor the usage of the shared network.Type: GrantFiled: April 29, 2003Date of Patent: February 10, 2009Assignee: Nokia CorporationInventors: Klas Johansson, Martin Kristensson, Uwe Schwarz, Annti Tölli

Patent number: 7474884Abstract: The present invention relates to a method for a digital receiver and a receiver exploiting second order statistics for adaptive co-channel interference rejection in wireless communication. It uses digitally I, in phase, and Q, quadrature, branches of a received transmitted signal as input to the receiver, a coarse synchronization and a coarse frequency offset compensation have being performed on the signal. It comprises a means for derotation, means for separation, means for filtering, means for estimating and means for detecting transmitted symbols in the received signal. The invention thereby improving co-channel rejection in wireless communication, thus making it possible to increase the number of communication channels for frequencies used.Type: GrantFiled: September 11, 2006Date of Patent: January 6, 2009Assignee: Nokia CorporationInventors: Martin Kristensson, Bjorn Ottersten, David Astély

Publication number: 20040166835Abstract: This invention concerns a method for controlling at least one radio bearer parameter of a first radio bearer (RB), and a Radio Bearer Control unit. The invention introduces a continuous monitoring and controlling of the RAB-RB parameter mapping for new and for already active connections. According to the invention a method for controlling at least one radio bearer parameter of a first radio bearer (RB) to be established or maintained between a mobile terminal and a first access-network node in a first cell of a cellular radio access network is provided. The first access-network node communicates with a core-network node in a core network to establish or maintain at least one radio access bearer (RAB) between the mobile terminal and the core-network node.Type: ApplicationFiled: June 25, 2003Publication date: August 26, 2004Inventors: Klas Johansson, Christian Braun, Martin Kristensson, David Soldani, Pekka Tapani Kohonen, Albert Hoglund, Benoist Guillard
