Patent number: 9204381Abstract: An apparatus (200) for use in a telecommunications system. The apparatus (200) comprising a memory (240) and a controller (210). The controller (210) is configured to receive a radio frequency bandwidth and identify a first candidate carrier frequency (710) from the received a radio frequency bandwidth. The controller is further configured to, for a first potential radio access technology determine a probability estimate (Prob) for the first candidate carrier frequency (710) being a carrier frequency of the first potential radio access technology, where in the probability estimate is based on a received power in a transmission band of the first potential radio access technology having the candidate carrier frequency (710) and on a received power in a guard band of the first potential radio access technology having the candidate carrier frequency and from this select a radio access technology based on the probability estimate (Prob) for the candidate carrier frequency (710).Type: GrantFiled: April 24, 2012Date of Patent: December 1, 2015Assignee: ST-ERICSSON SAInventor: Bjorn Engstrom

Publication number: 20070039678Abstract: The present invention relates to a method, a system, computer readable mediums and computer program products for controlling a process for producing a layered substrate. The method comprises the steps of: collecting (32) at least one first set of measurement data related to parameters of a substrate at a first process stage located upstream a pressing step in the translation direction (A) of the conveying means (14); collecting (34) at least one second set of measurement data related to parameters of the substrate at a second process stage located upstream a pressing step in the translation direction (A) of the conveying means (14); and controlling (36) resin dosage by using collected measurement data from the first and second process stage and a calculated calibration model, which model is based on collected measurement data of substrates at the first and/or second process stage.Type: ApplicationFiled: August 17, 2006Publication date: February 22, 2007Applicant: Akzo Nobel Coatings International B.V.Inventors: Bo Johnsson, Morgan Grothage, Bjorn Engstrom

Patent number: 6414312Abstract: A method for controlling a process for the production of a cellulose fiber containing product, during which at least two substances having a substantial influence on the same property of said product in correspondence to the relation between them are added, whereby a calibration model has been established by linking reference property values and corresponding reference relations, by means of a mathematical function, and in that the method comprises applying the calibration model on the actual relation in order to predict the property value; comparing the predicted property value with a desired target property value; and, if said predicted value is not substantially equal to said target value, adjusting the actual relation in a predetermined way; and repeating these operations until said predicted value is substantially equal to said target value.Type: GrantFiled: March 5, 1999Date of Patent: July 2, 2002Assignee: Akzo Nobel N.V.Inventors: Sofia Nordin, Bo Johnsson, Björn Engström

Patent number: 6080154Abstract: A locating anchor for a replacement ligament is described. The anchor comprises a bar which is operable to extend across the opening of a bone tunnel through which the replacement ligament passes. The bar has a number of characterising features. The bar may not include any lateral support, the bar may be recessed, the bar may have a fixing groove, preferably, for ligament sutures or fixing means may be provided at each end of the bar to fix the ends of the bar in the bone surrounding the tunnel opening. A method of fixation is also defined. The bar is particularly useful in avoiding hindrance to the surgeon caused by the necessity to thread sutures through the fixation device.Type: GrantFiled: March 20, 1998Date of Patent: June 27, 2000Assignee: Atlantech Medical Devices LimitedInventors: Clive Bruce Reay-Young, Nicholas Paul Woods, Bjorn Engstrom, S.o slashed.ren Winge

Patent number: 5965888Abstract: A method for determination of parameters of wood panels, which comprises analyzing the raw wood material/panels at a moisture content <10% by a spectrometric method giving spectral data, and comparing spectral data with reference data from reference material/panels calibrated to known parameters of panels produced from the reference material or of the reference panel by multivariate analysis. Control of process variables influencing parameters of the panels, which comprises analyzing the material/panels, linking spectral data into a combination with desired parameters, and comparing the combination with reference combinations consisting of reference data from reference material/panels linked with known parameters of the reference material/panels, the reference combinations being calibrated to known variables by multivariate analysis.Type: GrantFiled: December 31, 1997Date of Patent: October 12, 1999Assignee: Casco Products ABInventors: Bjorn Engstrom, Mona Hedqvist
