Patent number: 11595071Abstract: Methods, apparatus and computer programs are disclosed for controlling the output of a transmission point. One embodiment provides a method for controlling the output of a transmission point for a wireless communications network. The method includes determining an average output power of the transmission point, in a particular direction, over a period of time, comparing the average output power to an output power reference value, and allocating data, to be transmitted by the transmission point in the particular direction to one or more wireless devices, to a pool of radio resources. The pool of radio resources is adjusted as a function of the comparison between the average output power and the output power reference value.Type: GrantFiled: March 25, 2019Date of Patent: February 28, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Torbjörn Wigren, Christer Törnevik, Björn Thors

Patent number: 10432278Abstract: A method performed by a first communication device for managing beamforming by a second communication device for transmission of a signal. The first and second communication devices operate in a wireless communications network having a zone in which a radio frequency electromagnetic field strength is required by a regulation to be below a threshold. The first communication device adjusts at least one of an output power and a beam shape in the beamforming. The adjusting is such that the radio frequency electromagnetic field strength in the zone for the output power and the beam shape in the beamforming is below the threshold. The first communication device initiates transmission of the signal to a third communication device operating in the wireless communications network using beamforming with the adjusted at least one of the output power and the beam shape.Type: GrantFiled: May 18, 2016Date of Patent: October 1, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Henrik Asplund, Anders Furuskär, Eliane Semaan, Gustav Larson, Patrik Persson, Björn Thors, Christer Törnevik

Patent number: 9047373Abstract: This invention relates to efficiently performing a close-duplicate search within large collections of data streams, preferably in the context of Multimedia (audio and video files or streams). In a first aspect the present invention relates to a method for feeding information of a data from a data file or a data stream into a database. In a second aspect a method is provided for tagging or identifying a data stream by querying an unknown data or data stream to a database of known data streams. In a third aspect a computer program or suite of computer programs are provided to operate the methods of this invention. The robustness of the Multimedia Identifier system of the present invention results from the use of high-dimensional descriptors, which describe local interest points extracted from the frames of audio and/or video data.Type: GrantFiled: December 2, 2009Date of Patent: June 2, 2015Assignee: Háskólinn í ReykjavikInventors: Fridrik Heidar Ásmundsson, Björn Thor Jónsson, Kristleifur Dadason, Herwig Lejsek, Laurent Amsaleg

Patent number: 7202807Abstract: A method and an antenna arrangement are disclosed for reducing the antenna radar cross section for an externally illuminating radar source. A radar pulse is transmitted with the antenna arrangement fully matched to achieve a lowest possible power loss of the pulse. At all other times the antenna will be poorly matched and thereby will act as a low radar cross section. The reduced radar cross section leads to an antenna gain reduction, which most often can be accepted since competing noise is reduced as much as the useful signal. It is further suggested that the range gate of the receiver and the transmitter pulse control the antenna. Thus, the antenna is “fully opened” during the transmitting pulse and may be partly or “trade-off” matched during range gate reception. In the interval of not transmitting or receiving, the antenna will present a low radar cross section.Type: GrantFiled: October 24, 2002Date of Patent: April 10, 2007Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Lars Josefsson, Björn Thors
