Abstract: The innovative concept described herein relates to a magnetic angle sensor system having a rotatable shaft, a permanent magnet coupled to the rotatable shaft, and a magnetic field sensor arranged opposite the permanent magnet, wherein the magnetic field sensor is configured to detect a magnetic field prevailing in its detection region. The magnetic angle sensor system comprises means for reducing and/or compensating for an inhomogeneous stray field component of a per se homogeneous external magnetic stray field.

Abstract: According to one aspect of the disclosure, a method includes: receiving, by a magnetic field sensor, first and second magnetic field signals responsive to motion of a target; generating first and second digital pulse signals responsive to the first and second magnetic field signals, respectively; calculating a first time between a pulse edge of the first digital pulse signal and a next pulse edge of the second digital pulse signal; calculating a second time between two different pulse edges of the first digital pulse signal or two different pulse edges of the second digital pulse signal; calculating, using the calculated first and second times, a phase shift between the first and second magnetic field signals; and generating, using the calculated phase shift, a third magnetic field signal having a predetermined phase shift from the first magnetic field signal or from the first magnetic field signal.

Abstract: Facial movement of a wearer of a head-mountable display (HMD) is detected by detecting movement of a gasket of the HMD positioned against a face of the wearer using resistive or magnetic sensors within the gasket. A facial expression of the wearer is identified based on the detected facial movement.

Abstract: A semiconductor device includes a semiconductor substrate of a first conductivity type, and a vertical Hall element provided on the semiconductor substrate. The vertical Hall element includes an impurity diffusion layer of a second conductivity type and three or more electrodes. The impurity diffusion layer is provided on the semiconductor substrate and has an impurity concentration which increases as a depth increases. The three or more electrodes are provided in a straight line on a surface of the impurity diffusion layer and are composed of an impurity region of the second conductivity type having a higher concentration than the impurity diffusion layer.

Abstract: In one embodiment, a depassivating circuit includes a battery, a resistive load coupled to the battery, and a magnetic field sensor. The magnetic field sensor detects a presence of a magnetic field. The magnetic field sensor depassivates the battery by causing current from the battery to flow through the resistive load, in response to the presence of the magnetic field. The magnetic field sensor detects removal of the magnetic field. The magnetic field sensor ends depassivation of the battery, in response to the removal of the magnetic field.

Abstract: A method for use in the construction of tires is provided for sensing spacing between a plurality of radial cables in a tissue is provided. The method utilizes a probe that has a first magnet, a second magnet, a magnetic bridge, and a spacing hall effect sensor. The magnets are spaced from one another in a probe first length direction, and the spacing hall effect sensor is located between the magnets in the probe first length direction. The spacing hall effect sensor is located between the magnetic bridge and the cables in a probe second height direction when the probe is positioned next to the partially constructed tire. The probe is placed next to the partially constructed tire such that the first cable direction is not parallel to the probe first length direction. The probe is then used to sense spacing between successive ones of the cables.

Abstract: Disclosed are a cooling unit and a cooking appliance including the same. An operation detecting module that senses rotation of a cooling fan includes a magnetic member that generates a magnetic force, a detector that senses the magnetic force, and an adjustment member that opens and closes a passage where the magnetic force passes between the magnetic member and the detector, and when the cooling fan rotates, the adjustment member operates such that a first operation of opening the passage and a second operation of closing the passage alternate repeatedly.
