A system is configured to model a magnetic field by measuring a first value for characteristics of a magnetic field at a first position in the magnetic field. The system measures a second value characteristics of the magnetic field at a second position in the magnetic field. The system determines a distance between the first position and the second position. The system estimates a distortion component of the magnetic field at approximately the second position in the magnetic field based on each of the distance, the first value for each of the one or more characteristics, and the second value for each of the one or more characteristics. The system outputs a model of at least a region of the magnetic field.

An apparatus is disclosed for identifying a target region along a surface of a barrier corresponding to a plane defined along a member, where the member is occluded from view by nature of the barrier. The apparatus includes a measurement device and a magnet assembly. The magnet assembly generates a magnetic field, and is positioned along a predetermined location of the member over a first side of the barrier. The measurement device is positioned over a second side of the barrier and measures properties of the magnetic field to identify the target region in general alignment with the plane.

A method for configuring a device for non-destructive testing of a mechanical part, the device including an optical motion-tracking system, a non-destructive testing probe fixedly linked to a first rigid body, and a pointing device, includes steps of: learning of an origin and of axes of an examination area of the surface of the mechanical part using the pointing device, in a coordinate system linked to the optical motion-tracking system, so as to define a coordinate system linked to the examination area, learning of an origin and of axes of an emitter and receiver surface, called active surface, of the probe using the pointing device, in a coordinate system linked to the first rigid body of the probe, and determination of the position and of the orientation of the active surface of the probe, in the coordinate system linked to the examination area.

A method is provided for identifying cookware items placed on top of an induction cooktop having a plurality of coils. The method includes the following steps: acquire coverage factor information for each coil and collect it into a matrix; identify all local maxima in the matrix; find the coordinates of each of the local maxima as follows: when the local maxima is a single coil, the coordinates are those of the coil center, and when the local maxima is a region of contiguous coils, the coordinates are those of a centroid of the region; calculate distances from each coil to each of the coordinates of the identified local maxima; determine a minimum among the distances; classify the coils in clusters, based on the distances from the local maxima; and use the identified coil clustering to estimate the position, shape, size, and orientation of the cookware items.

A wearable magnetic sensor system includes a wearable article that spatially arranges magnetic sensor components around a user's torso to obtain magnetic sensor data used for body pose tracking. The wearable magnetic sensor system includes magnetic sensor components that sense a magnetic field generated by a magnetic transmitter. One or more wearable articles spatially arrange the magnetic sensor components at different locations on a body of the user, such as the arms and torso. The one or more wearable articles include a transmitter attachment mechanism for affixing the magnetic transmitter at, e.g., a torso of the user, and receiver attachment mechanisms for affixing the magnetic sensor components at, e.g., locations of the body other than the torso. The magnetic sensor components are spatially arranged at different locations on the user's body so as to maximize tracking accuracy and minimize interference between the magnetic sensors and the transmitter.

A position detection device detects a current positon of a operation member among positions including a predetermined position and includes a detection system that includes a part to be detected and 3N magnetic sensors S. The operation member can move to the positions in N (≥3) different directions from the predetermined position. Movement of the operation member between the predetermined position and another position cause outputs from three of the magnetic sensors to be switched. The magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a first position are all different from the magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a second position.
