A device compensates for the an influence of a magnetic field gradient which may be generated due to a component geometry of a component (1). The device includes at least two magnetic field sensors (17, 18) which are arranged outside of the magnetic balance of the ferromagnetic component (1). The at least two magnetic field sensors (17, 18) each have a differing sensitivity. One of the magnetic field sensors (17, 18) is exposed to the influence of the magnetic field gradient to a greater extent compared to the other magnetic field sensor due to its spatial arrangement relative to the ferromagnetic component (1). The one magnetic field sensor may have a sensitivity lower than the other magnetic field sensor.

A sensor is configured to detect a tensile, compressive and/or bending forces acting on a carrier (1, 1) of the sensor. The carrier (1,1) has at least one planar magnetizable surface (2). The sensor (13) comprises at least two sensor coils (12, 15) which are arranged at a predetermined angle to a longitudinal axis (14) of the carrier (1, 1). The sensor (13) may be positioned on either side of the carrier (1, 1). The sensor (13) is capable of detecting changes of the magnetisation due to tensile, compressive and/or bending forces acting on the carrier (1, 1).

Examples of a power peak shaving system are presented. In one example, the power peak shaving system includes a power directing circuit and a control circuit. The power directing circuit may direct power received from at least one of an alternating current (AC) supply voltage or an energy storage unit to generate an output voltage for a load. The control circuit may control the power directing circuit to supplement power received from the AC supply voltage with power received from the energy storage unit to supply power drawn by the load at the output voltage to prevent the power received from the AC supply voltage from exceeding a threshold level.


An assembly for providing haptic effects includes a panel adapted to be mated to another structure, a frame placed around and spaced apart from the panel, at least one flexible coupling to connect the panel to the frame, a display connected to the panel so as to be stationary with respect to the panel, and a touch screen assembly connected to the frame. The touch screen assembly is placed over the display.


A magnetoelastic torque sensor system (10) for a drive train (12) is described which comprises a primary sensor unit (14) having at least one magnetoelastic portion (40) formed by a magnetoelastic material for reacting on an occurring stress due to torque generated by an engine (20), particularly torque contribution of an individual cylinder (22) of an engine (20). The magnetoelastic material is configured to generate a magnetic field and/or alternate an already existing magnetic field in response to the stress. The magnetoelastic torque sensor system (10) also comprises a secondary sensor unit (16) having at least one magnetic sensitive part (18), in particular a fluxgate, which measures the generated magnetic field or the alternating magnetic field of the magnetoelastic portion (40). The magnetoelastic torque sensor system (10) also comprises an electronic control unit (32) for receiving and processing the signals provided by the secondary sensor unit (16), wherein the electronic control unit (32) in particular controls and/or reads out the at least one magnetic sensitive part (18) of the secondary sensor unit (16) and generates a signal which correlates with the stress applied to the primary sensor unit (14). Further, a drive train (12), a method of measuring torque in a drive train (12), a method of operating a drive train (12) and a method of manufacturing a primary sensor unit (16) are described.

A device for determining an external magnetic influence has a component comprising ferromagnetic material and a magnetizable region comprising at least three opposing magnetic tracks. The at least three magnetic opposing magnetic tracks are magnetizable in opposite directions, form at least two groups, and are arranged axially relative to the component. A first magnetic field sensor for emitting a signal is arranged radially to the component and assigned to the first group. A second magnetic field sensor for emitting a signal is arranged radially to the component and assigned to the second group. Redundant magnetic field sensors, each configured for emitting a signal, may be arranged radially in relation to the component for each of the first and second groups. The signals of the first and the second sensors can be set in relation to each other and in relation to the signals of the redundant first and second sensors.
