Patents by Inventor Patrick Calandrini

Patrick Calandrini has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9222807
    Abstract: A method is provided for producing a magnetic position or path sensor element, the magnetic position or path sensor element having at least one magnetic pathway that extends along a displacement path and that has a plurality of magnetic north-south transitions, as well as at least one magnetic sensor mounted so as to be movable relative to the magnetic pathway. At least one of the magnetic north-south transitions is defined as a critical north-south transition whose position is to be detected with a specified degree of precision. Adjacent to the critical north-south transition are situated magnetic poles having identical polarity. The method provides production reliability by reducing the sensitivity of the magnetic position or path sensor element to positional tolerances.

  • Patent number: 8729888
    Abstract: A magnetic transducer configuration may include a permanent magnet element magnetized in its longitudinal direction having a pole transition. The permanent magnet element has a cross section in the pole transition section, which is larger than the cross section of the permanent magnet element in an area outside of the pole transition section. A magnetic position sensor may include a magnetic field sensor array and magnetic transducer configuration. The magnetic field sensor array and the magnetic transducer configuration are situated displaceably in the longitudinal direction in a plane-parallel manner. The magnetic field sensor array has at least one magnetic field sensor lying in a path along which the permanent magnet element moves during displacement of the magnetic transducer configuration.

  • Publication number: 20110234207
    Abstract: A magnetic transducer configuration is described having at least one permanent magnet element, which is magnetized in its longitudinal direction and has a pole transition of the longitudinal section having a pole transition. The permanent magnet element has a cross section in the pole transition of the longitudinal section, which is larger than the cross section of the permanent magnet element in an area outside of the pole transition of the longitudinal section. A magnetic position sensor is also described having a magnetic field sensor array and the magnetic transducer configuration according to the present invention. The magnetic field sensor array and the magnetic transducer configuration are situated displaceably in the longitudinal direction to one another in a plane-parallel manner.
