Patent number: 8471911Abstract: In a night vision arrangement for a motor vehicle a camera is provided which captures an image which is subsequently displayed on a display arrangement which may be a head-up display arrangement. The camera directs light on to a beam deflector which may be constituted by a mirror which deflects the beam so that it passes along a neck on to a sensor. The camera may relatively easily be mounted in position in a motor vehicle.Type: GrantFiled: August 20, 2007Date of Patent: June 25, 2013Assignees: Autoliv Development AB, Flir Systems, Inc.Inventors: Jan-Erik Kallhammer, Dick Eriksson, Lars Karlsson, Staffan Straat

Patent number: 8228379Abstract: In a night vision arrangement for a motor vehicle in which a camera captures an infra-red image of the roadway in front of the vehicle, a video signal generated by the camera is processed by a signal processor so that the field of view of the image displayed by a display unit is selected in accordance with a control signal. The control signal is generated by a signal generator which is responsive to one or more parameters of the movement of the vehicle. The width of the field of view may be decreased with increasing speed. The axial direction of the field of view may be adjusted depending upon the nature of a turning movement of the vehicle.Type: GrantFiled: February 5, 2008Date of Patent: July 24, 2012Assignees: Autoliv Development AB, Flir Systems, Inc.Inventors: Jan-Erik Kallhammer, Dick Eriksson, Lars Karlsson, Staffan Straat

Publication number: 20090005959Abstract: In at least one embodiment of the present invention a driving aid system for mounting in a road vehicle is provided. The driving aid system comprises a detection system for detecting and storing profiles of characteristics of objects around the vehicle along a road on which the vehicle is being driven. A positioning system is for providing a current position of the vehicle. Profiles of characteristics of objects are stored in relation to the detected position of the vehicle. A processing arrangement compares currently detected profiles with earlier stored profiles and, if a match between a currently detected profile and an earlier stored profile is found, then the current position of the vehicle is determined relative to an object corresponding to the earlier stored profile, and the same or other earlier stored profiles is used to predict the future surroundings of the vehicle.Type: ApplicationFiled: March 9, 2007Publication date: January 1, 2009Inventors: Jonas Bargman, Jan-Erik Kallhammer

Publication number: 20060188246Abstract: Systems and methods provide infrared camera techniques that may improve image quality or infrared camera performance over a range of varying conditions. For example, in accordance with an embodiment of the present invention, a system is disclosed that transforms data provided by an infrared camera based upon environmental conditions at the time the data was obtained. As an example, the image quality provided by the infrared camera may be improved over a range of environmental conditions by the proper transformation of the data based upon the sensor's information.Type: ApplicationFiled: February 23, 2005Publication date: August 24, 2006Inventors: Bill Terre, Joseph Kostrzewa, Jan-Erik Kallhammer, Tobias Hoglund

Publication number: 20030107204Abstract: An air-bag arrangement provides protection for the occupant of a motor vehicle. The air-bag arrangement incorporates an airbag (50) formed by two layers of fabric (51, 52) interconnected to form a first set of chambers (53, 54, 55, 56, 57, 58), having a plurality of elongates substantially parallel chambers. A further fabric layer (61) is connected to one of the two layers (52) forming the main part of the inflatable element to define a second chamber set including two chambers (62, 63). These chambers are off-set from the adjacent chambers (54, 55, 56) defined by the first two layers (51, 52). Apertures (59, 60) provided in the layer (52) provide means for inflating the second set of chambers (62, 63).Type: ApplicationFiled: August 30, 2002Publication date: June 12, 2003Inventors: Norbert Drossler, Jan-Erik Kallhammer
