Patent number: 8356473Abstract: A device is provided for injection of a liquid agent, such as fuel or reducing agent, into the exhaust line from a combustion engine. The device (1) has a nozzle arrangement (20) having a nozzle head (21), from which the liquid agent is injectable into the exhaust line. The nozzle arrangement (20) has a first conduit (22) leading to the nozzle head (21) for supply of compressed gas, preferably in the form of compressed air, to the nozzle head, and a second conduit (23) leading to the nozzle head (21) for supply of the liquid agent to the nozzle head. The nozzle head (21) is provided with at least one outlet opening (24) connected to the first conduit (22) and to the second conduit (23), through which outlet opening the liquid agent is injectable into the exhaust line under atomization thereof after mixing with compressed gas in a mixing zone (25) inside the nozzle head.Type: GrantFiled: February 6, 2007Date of Patent: January 22, 2013Assignee: STT Emtec ABInventors: Micael Blomquist, Magnus Thorsell, Sören Andersson, Claes Åkerlund

Patent number: 8055300Abstract: Devices and methods to use base stations to communicate with user equipment (UE) terminals in an indoor setting are disclosed. For example, user equipments such as mobile telephone devices may be used in a building with multiple floors. The building may be supplied with antenna elements organized into antenna groups with each group serving an area of the building—a floor for example. The base station, utilizing the antenna groups, communicates with the UE terminals via one or more radio resources. The base station manages radio resources to communicate with multiple UE terminals. The base station selectively activates and deactivates the antenna groups to reduce multiple access interference and to efficiently utilize the radio resources.Type: GrantFiled: August 29, 2007Date of Patent: November 8, 2011Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sören Andersson, Jiuhui Du

Patent number: 6650910Abstract: The present invention relates to radio systems and, more particularly, to a method and apparatus for receiving radio signals with the aid of beams generated by antenna assemblies. For each of the beams in a first of the antenna assemblies there is a beam in the second of the antenna assemblies that covers the same space area. Signals received by the second are delayed relative to signals received by the first of the antenna assemblies. Then signals from the first antenna assembly are combined with signals from the second of the antenna assemblies. The combined signals derive from beams covering the same space area. Each combined signal is then radio received in a joint radio receiver. A DOA-estimation can be calculated on the basis of radio received signals derived from all beams.Type: GrantFiled: November 20, 1998Date of Patent: November 18, 2003Assignee: Telefonaktiebolaget LM EricssonInventors: Sara Mazur, Bo Hagerman, Ulf Forssén, Sören Andersson, Fredrik Ovesjö

Patent number: 6470177Abstract: The present invention relates generally to the problems associated with sectorization of cells in cellular communications systems, and more particularly to interference between sectors. The invention provides the possibility of flexibly distributing hardware between sectors in a cell by allowing one transmitter to be shared by all the sectors. Since a beacon signal must be transmitted to each sector in a cell, it can be combined with the signal from the transmitter before being transmitted from an antenna. Thus it is necessary to only deploy one carrier for the beacon. Interference reduction in sectored sites is also improved. In addition, different antenna patterns may be combined to provide the site with all kinds of coverage patterns. Downlink diversity is furthermore attainable by having overlapping uncorrelated antenna patterns.Type: GrantFiled: April 14, 2000Date of Patent: October 22, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sören Andersson, Henrik Dam, Magnus Berg, Marc Frerich, Felix Ahrens, Rainer Bormann

Patent number: 6342192Abstract: The invention relates to a catalyst for cleaning the exhaust gases from internal combustion engines, especially diesel engines, comprising a monolithic body having longitudinally extending, open throughchannels coated with a surface-enlarging washcoat layer which contains one or more catalytically active precious metals. In order to reduce the tendency of the catalyst to oxidize and absorb (be enriched with) sulphur dioxide, the washcoat layer of the catalyst is based on silicon carbide and is substantially free from aluminum oxide. A method for preparing the catalyst, the use of the catalyst, as well as an exhaust gas cleaning system and a motor vehicle equipped with the catalyst, are also disclosed.Type: GrantFiled: October 7, 1994Date of Patent: January 29, 2002Assignee: Johnson Matthey PLCInventors: Sören Andersson, Magali Boutonnet Kizling

Patent number: 6339399Abstract: A method and a system for calibrating the reception and transmission of an antenna array for use in a cellular communication system is disclosed. The calibration of the reception of the antenna array is performed by injecting a single calibration signal into each of a number of receiving antenna sections, in parallel. The signals are collected after having passed receiving components that might have distorted the phase and amplitude. Correction factors are generated and applied to received signals. The calibration of the transmission of the antenna array is preformed in a similar way. A single calibration signal is generated and injected into each of a number of transmitting antenna sections, one at a time. The signals are collected, one at a time, after having passed transmitting components that might have distorted the phase and amplitude. Correction factors are generated and applied to signals that are to be transmitted.Type: GrantFiled: June 26, 2000Date of Patent: January 15, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sören Andersson, Ulf Forssén, Fredrik Bengt Ovesjö, Sven Oscar Petersson

Patent number: 6236364Abstract: To improve null depths in an antenna pattern of a first polarization, formed with nulls in at least one angular region, a further antenna pattern of a second polarization, substantially orthogonal to the first polarization, is concurrently formed. In the angular region, the amplitudes of the copolar components of the further antenna pattern are substantially equal to the amplitudes of the crosspolar components of the antenna pattern of the first polarization, and the phases of the copolar components of the further antenna pattern of the second polarization are substantially opposite to the phases of the crosspolar component of the first polarization.Type: GrantFiled: September 29, 1999Date of Patent: May 22, 2001Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Sven Petersson, Björn Johannisson, Sören Andersson
