摘要： An electrical device includes a magnetic sensor circuitry (101) for detecting magnetic field and for generating a detection signal in response to the detected magnetic field, and a control circuitry (102) for controlling operation of the electrical device in accordance with the detection signal. The magnetic sensor circuitry is configured to detect a direction related to a deviation of the magnetic field from the magnetic field of the earth, and the control circuitry is configured to control the operation of the electrical device in accordance with the detected direction. The electrical device can be controlled by using e.g. a permanent magnet (105) for directing, to the magnetic sensor circuitry, magnetic field deviating from the magnetic field of the earth and having a desired orientation. Thus, the electrical device can be controlled without an electrical connector or a radio interface.

摘要： A method, including generating a magnetic field in a region from a first magnetic field radiator located at a first position and a second magnetic field radiator located at a second position. A volume having a multiplicity of vertices is delineated within the region, and respective values of the magnetic field at the multiplicity of vertices are measured. In response to the respective values, respective first dipole moments to the first magnetic field radiator and respective second dipole moments to the second magnetic field radiator are assigned. A value of the magnetic field within the volume is calculated in terms of the first dipole moments and the second dipole moments.

摘要： Provided is a linear motion and rotation drive apparatus capable of minimizing inertia due to a magnetic scale attached to an output shaft when the output shaft is linearly moved or rotate. A linear motion and rotation drive apparatus (1) includes an output shaft (2), a linear motor (3), a rotational motor (4), a ball spline bearing (5), a magnetic scale (8), a first magnetic detection element (41) configured to detect a linear motion, and a second magnetic detection element (42) configured to detect a rotational motion. The magnetic scale (8) includes a lattice-shaped magnetized pattern (37) in which S poles and N poles are alternately arranged in an axis L direction and S poles and N poles are alternately magnetized in a direction around the axis (L) on a circumferential surface thereof in the direction around an axis (L). The first magnetic detection element (41) and the second magnetic detection element (42) are disposed to face the magnetized pattern (37). Since a linear motion position and a rotating position can be detected using the first magnetic detection element (41) and the second magnetic detection element (42) that face the same magnetized pattern (37), a size of a linear motion and rotation detector (7) in the axis L direction is not increased and a weight thereof is not increased.
