摘要： A sensor for sensing an external magnetic field along a sensing direction comprises a sensor bridge. The sensor bridge has a first sensor leg that includes a first magnetoresistive sense element and a second sensor leg that includes a second magnetoresistive sense element. The first and second sense elements have respective first and second pinned layers having the same reference magnetization. The first and second sense elements have respective first and second sense layers, each self-biased to have a first sense magnetization. A permanent magnet layer is proximate the second sense element. In the absence of an external magnetic field, the permanent magnet layer magnetically biases the first sense magnetization of the second sense layer produce a second sense magnetization of the second sense layer that differs from the first sense magnetization, and the first sense layer of the first sense element retains the first sense magnetization.

The device further comprises a sensor (28) at the distal end portion of the shaft that comprises first (321) and second (322) leads extending therefrom to the proximal end portion (24) of the shaft. The device further comprises an electromechanical connector (30) having a plurality of pins (40) at a first end thereof. First (401) and second (402) of the pins are electrically connected to the first and second sensor leads, respectively, thereby forming a first partial magnetic loop between the first and second pins. The connector further comprises first and second jumpers (68) electrically connecting the first pin and third (403) pins, and second and fourth (404) pins, respectively, thereby forming a second partial magnetic loop. The partial magnetic loops are configured to combine with partial magnetic loops of a second connector (56), to which the first connector is mated, to form a pair of magnetic noise cancellation loops.

摘要： An integrated AMR magnetoresistive sensor (20) having a magnetoresistor (21), a set/reset coil (22), and a shielding region (23) arranged on top of each other, with the set/reset coil (22) arranged between the magnetoresistor and the shielding region. The magnetoresistor (21) is formed by a magnetoresistive strip (24) of an elongated shape having a length in a first direction (X) parallel to the preferential magnetization direction (EA) and a width in a second direction (Y) perpendicular to the first direction. The set/reset coil (22) has at least one stretch (34a, 34b) extending transversely to the magnetoresistive strip. The shielding region (23) is a ferromagnetic material and has a width in the second direction (Y) greater than the width of the magnetoresistive strip (24) so as to attenuate the external magnetic field (H) traversing the magnetoresistive strip (24) and increasing the sensitivity scale of the magnetoresistive sensor.

摘要： The present invention introduces a method, apparatus and computer program for magnetic resonance imaging or magnetoencephalography applications in order to control currents of a coil assembly (20), and thus achieving desired magnetic fields precisely in the measuring volume (21). The approach is an algebraic method where a field vector is generated for the test currents of each coil (20). Vector and matrix algebra is applied and a linear set of equations is formed. Field components and their derivatives up to the desired order can be taken into account. Principal component analysis or independent component analysis can be applied for determination of the dominant external interference components. By checking the condition value for the matrix (33, 45), it is possible to investigate whether a reasonable solution of currents for desired magnetic fields is possible to achieve. Finally, solved currents can be installed into a current supply unit (29) feeding the coils of the assembly (20). The invention can be applied as an active compensation feature for different interference shapes in the MEG application (25), or for the precise creation of the fields and gradients in the MRI application (24).

摘要： A magnetic shielding apparatus includes: a passive shield; a correction target space that is defined in the interior of the passive shield; external coils as a first coil that corrects a magnetic field in the passive shield; a first magnetic sensor; a second magnetic sensor that is arranged more inside the passive shield than the first magnetic sensor; and a control unit. The first magnetic sensor and the second magnetic sensor measure a magnetic field gradient in the passive shield. The control unit controls the external coils based on a result of the measurement performed by the first magnetic sensor and the second magnetic sensor.
