Patent number: 8195285Abstract: A method and sensor assembly for determining the condition of a structure, especially for confirming if a measured fingerprint is on a live finger, measures characteristics of close to the structure surface. The sensor includes a first pair of current supply electrodes coupled to a current source, providing an electrical current to the skin, at least two pickup electrodes at chosen and different positions relative to the current supply electrodes, at least a first of the pickup electrodes being coupled to an instrument for measuring the voltage between the first pickup electrode and at least one of the pickup or current supply electrodes, storage for a predetermined set of values characterizing a certain condition of the surface, and means for comparing the characteristics from each pickup electrode with the measurements of the other pickup electrodes and with the predetermined set of characteristics for determining the surface condition.Type: GrantFiled: December 6, 2010Date of Patent: June 5, 2012Assignee: Idex ASAInventors: Orjan G. Martinsen, Jon Nysaether, Knut Riisnaes, Ingvild Juvkam Dyve, legal representative, Geir Mostad, Rune Pedersen, Nicolai W. Christie, Sigmund Clausen

Patent number: 7606398Abstract: A sensor device for performing measurements on an at least partially conductive surface includes a number of conductive structures at or directly below the sensor surface. The conductive structures consist of at least one stimulation or current sink electrode and a number of sensor elements coupled to interrogation electrodes in an electronic circuit for measuring impedance between the electrodes and the stimulation electrode. The sensor device also includes at least one additional clamping electrode positioned in the vicinity of the sensor elements and coupled to a chosen voltage.Type: GrantFiled: December 6, 2002Date of Patent: October 20, 2009Assignee: IDEX ASAInventors: Jon Nysæther, Knut Riisnæs, Ingvild Juvkam Dyve, legal representative, Ørjan G.

Patent number: 6340440Abstract: A method for producing a tubular container of plastic material, in which the plastic material is supplied to an injection mould (3) which forms therein a blank (1) including a blank body (15) with a tubular portion (16). The tubular portion is open at one end (11) and has, in its other end (10), an emptying aperture or mouth (12) of the future container with a closure device thereat. The tubular portion (16) is displaced or drawn through an annular gap (4) for reduction of the wall thickness and axial extension thereof. After extension, the tubular portion is cut to the desired length. The thickness of the drawn material is between 0.1 and 0.15 mm. The closure device is confined within an outline formed by the drawn wall of the tubular portion.Type: GrantFiled: October 10, 2000Date of Patent: January 22, 2002Assignee: Plastech A.p.S.Inventor: Jan Rune Pedersen

Patent number: 5656225Abstract: A method for producing a squeezable, thin-walled tube container of orientable plastic material in which the container includes a mouth portion, a squeezable thin-walled tubular container body having an open bottom-forming portion and a connecting portion located between the mouth portion and the container body and in which the mouth portion and the connecting portion consists of non-oriented material includes forcing the non-oriented material in the tube portion, by mechanical means, through a gap with a gap width at most amounting to approximately half the wall thickness of the material in the tube portion for orientation of the material passing through the gap, thereby obtaining substantially monoaxial orientation of the material which forms the container body and the open bottom-forming portion of the thin-walled squeezable tube container.Type: GrantFiled: June 2, 1995Date of Patent: August 12, 1997Assignee: PLM ABInventor: Jan Rune Pedersen
