Patent number: 10765343Abstract: A method of obtaining information about the position and/or orientation of a magnetic component relatively to a magnetometric detector, the magnetic component and the magnetometric detector being moveable independently from each other relatively to a static secondary magnetic field, the method comprising the steps of: measuring in the presence of the combination of both the magnetic field of the magnetic component and the static secondary magnetic field essentially simultaneously the strength and/or orientation of a magnetic field at at least a first position and a second position spatially associated with the magnetometric detector, the second position being distanced from the first position; and combining the results of the measurements to computationally eliminate the effect of the secondary magnetic field and derive the information about the position and/or orientation of the magnetic component.Type: GrantFiled: November 30, 2016Date of Patent: September 8, 2020Assignee: eZono AGInventors: Rolf Henkel, Eliseo Ventura Sobrino Patino, Robert Von Offenberg Sweeney, Allan Dunbar

Patent number: 9459087Abstract: In a magnetic position detection system designed to detect a target object in a detection space using an array of magnetic sensors, the position of the target object can be determined by fitting a model of the target object's magnetic field to the sensor measurements. A robust determination of whether a target object is present can be obtained by fitting the model to the sensor measurements and determining the remaining differences between the fitted model and the sensor measurements. If the differences are high then the model is not fitting well, suggesting that the target object is not present. If the differences are low, the model is fitting well and the target object can be determined as being present. Measurements made when the target object is determined as not being present can be regarded as background field measurements including any stray fields.Type: GrantFiled: March 5, 2013Date of Patent: October 4, 2016Assignee: EZONO AGInventors: Allan Dunbar, Rolf Henkel

Patent number: 6980210Abstract: The invention pertains to an image processing device, in particular a device for stereoscopic image processing, and to a coherence detector used thereon. The image processing device can process stereoscopic images in real time and can be implemented with simple means and low expense. Two alternative embodiments of the coherence detector are disclosed. The image signals can be processed at the speed that they are supplied by image receivers, and thus image data processing is possible to attain depth information with little expense and in real time.Type: GrantFiled: November 24, 1998Date of Patent: December 27, 2005Assignee: 3-D Image Processing GmbHInventors: Gerhard Weiglhofer, Fritz Pauker, Rolf Henkel
