  • Patent number: 10564004
    Abstract: A magnetic proximity sensor includes first and second spaced wings. Each wing has a protrusion extending outwardly from an edge near or at a corner thereof. The protrusions face each other to provide a narrow gap area. A magnetic assembly secured to each of the wings extends across the gap and is spaced from the protrusions. A magnetic sensor element is disposed at the narrow gap area. The magnetic assembly projects magnetic flux toward the first wing. Magnetic flux passes via the first wing and the protrusion thereof and crosses the narrow gap area to the protrusion of the second wing. The second wing provides a return path for magnetic flux to the magnetic assembly. The magnetic proximity sensor senses decreased magnetic flux when a target approaches.

  • Patent number: 10551259
    Abstract: A stator to guide a location-dependent magnetic field in a circumferential direction around a rotation axis. In one example, the stator includes a first stator ring revolving around the rotation axis, and a second stator ring revolving around the rotation axis and arranged concentrically with the first stator ring. The first and second stator rings include claws which are arranged so as to revolve around the rotation axis and at a distance from one another in the circumferential direction and engage with one another at least on a toothing axial plane. The claws are separated from one another by an air gap so that, when the magnetic field is arranged in the toothing axial plane, the magnetic field is guided towards the stator rings via the claws according to a relative angular position. Each claw has the contour of a mathematically smooth curve when viewed across the circumferential direction.

The switch can have a normal operating condition in which the first terminal is electrically connected to the second terminal. The switch can have a fault condition in which the first terminal is electrically connected to both the second terminal and the third terminal, causing a majority of the current to flow between the first terminal and the third terminal and a minority of the current to flow between the first terminal and the second terminal. The breaker can include a positive temperature coefficient (PTC) resistor between the first terminal and one of the second and third terminals. The thermally-activated switch can be integrated into a variety of structures, for example, a battery pack which can house one or more cells.

The linear position can be representative of a turn number of the shaft. The method can further include determining an angular position of the shaft within a given turn with a second magnet positioned at an end of the shaft along the longitudinal axis and arranged relative to a second magnetic sensor. The method can further include combining the turn number with the angular position to generate one or more output signals representative of a measured rotational position of the shaft.
