Patent number: 8963537Abstract: A device for measuring a current flowing through an electric cable comprises a printed circuit board, a magnetic field sensor and a ferromagnetic component. The ferromagnetic component comprises two tongues whose front faces are disposed opposite of each other and are separated by an air gap and further comprises at least two feet, with the tongues and/or the feet being bent off. The cable is guidable through an opening which is enclosed by the ferromagnetic component. The ferromagnetic component and the magnetic field sensor are mounted on a surface of the printed circuit board. The magnetic field sensor is sensitive to a magnetic field extending parallel to the surface of the printed circuit board. The tongues of the ferromagnetic component extend parallel to the surface of the printed circuit board (2).Type: GrantFiled: May 30, 2012Date of Patent: February 24, 2015Assignee: Melexis Technologies NVInventors: Robert Racz, Peter Krummenacher

Patent number: 4674514Abstract: A real-time method and appartus is disclosed for scanning large body areas to produce an ultrasound cross-sectional picture of the area in which at least two different and partially overlapping sector scans of the body are carried out in one scanning plane by the pulse-echo method utilizing an ultrasound transducer unit having a rigid transducer which is pivotable about an axis of oscillation perpendicular to the scanning plane, which performs an oscillatory movement about the axis of oscillation and between two end positions on each scan, and which is segmented into adjacent transducer elements. In performing the scans, at least two different transducer sets are used, each containing one or more transducer elements, each transducer set being used both for the emission of the ultrasound pulses and for the reception of echo waves. In all the scans the position of the axis of oscillation remains unchanged with respect to the body.Type: GrantFiled: September 23, 1985Date of Patent: June 23, 1987Assignee: Kontron Holding AGInventors: John G. Abbott, Christoph B. Burckhardt, Pierre-Andre Grandchamp, Peter Krummenacher, Claude Schlaepfer

Patent number: 4649926Abstract: A real time method and apparatus is disclosed for scanning large body areas to produce an ultrasound cross-sectional picture of a body in which method at least two different and partially overlapping sector scans of the body are carried out in one scanning plane by the pulse-echo method utilizing single ultrasound array. The array is rotatable about an axis of rotation perpendicular to the scanning plane and comprises at least a first and a second transducer, disposed in spaced relationship along a circle which is situated in the scanning plane and which is concentric with the axis of rotation. Out of at least two different scans, one is performed with the first transducer and the other with the second, each transducer being used both for the emission of ultrasound pulses and for the reception of echo waves and the position of the axis of rotation with respect to the body remaining unchanged during all the scans.Type: GrantFiled: September 23, 1985Date of Patent: March 17, 1987Assignee: Kontron Holding AGInventors: John G. Abbott, Christoph B. Burckhardt, Pierre-Andre Grandchamp, Peter Krummenacher, Claude Schlaepfer

Patent number: 4649927Abstract: A method and apparatus for producing a compound ultrasound cross-sectional picture of a body, in which method a plurality of partially overlapping body scans are carried out line-wise by the pulse-echo method in one scanning plane, thereby producing image signals in digital form corresponding to the received echoes. For the real-time display of the compound cross-sectional pictures, the set of image signals produced with each scan is stored in a separate digital storage unit, at least some of the stored sets of image signals are immediately combined with one another to generate a new set of image signals corresponding to a compound real-time cross-sectional picture, and the new set of image signals is immediately fed to a television monitor in order to display the compound real-time cross-sectional picture.Type: GrantFiled: September 23, 1985Date of Patent: March 17, 1987Assignee: Kontron Holding AGInventors: Rainer Fehr, Pierre-Andre Grandchamp, Peter Krummenacher

Patent number: 4628738Abstract: An ultrasonic imaging apparatus for operation in either or both linear and sector scan modes is disclosed which employs a common array of transducers. Circuitry is provided for controlling the order and timing of pulse echo transmission and reception, which further include control circuitry to operate variable delay and switching circuitry to generate transmission signals to be applied to the transducers, and to direct echo signals received by the transducers for processing to provide the image of the structures being inspected. Suitable interconnection/switching circuitry is provided so as to minimize prior art requirements for use of different elements for the separate scanning modes, with concomitant expenses associated with the larger number of components being reduced.Type: GrantFiled: February 19, 1986Date of Patent: December 16, 1986Assignee: Hoffmann-La Roche Inc.Inventors: Christoph B. Burckhardt, Rainer Fehr, Peter Krummenacher
