The sensor portions of the magnetic property detection members are fixedly coupled to each other by an adhesive. | 2014-10-30 |
20140320116 | METHOD FOR DIAGNOSING A VARIABLE RELUCTANCE MAGNETIC DETECTION HEAD, AND DETECTION CIRCUIT - A variable-reluctance magnetic detection head delivers an electrical signal (Uin) and a rising wavefront of the electrical signal is compared with a first threshold (Th) in order to switch from a first state (B | 2014-10-30 |
20140320117 | METHOD FOR PRODUCING MAGNETO-RESISTIVE EFFECT ELEMENT, MAGNETIC SENSOR, ROTATION-ANGLE DETECTION DEVICE - A magnetic sensor includes a plurality of magneto-resistive effect elements each configured by using a magneto-resistive effect film formed by laminating a pinned layer, a nonmagnetic layer, and a free layer in order from a side of a substrate. A first linear pattern is formed in a first portion on the substrate in a first direction. A second linear pattern is formed in a second portion on the substrate in a second direction. A magnetization direction of the first portion is different from a magnetization direction of the second portion. The magneto-resistive effect film is further formed on the substrate. Each of the plurality of magneto-resistive effect elements includes a pair of electrodes formed by the magneto-resistive effect film processed into a predetermined shape. | 2014-10-30 |
20140320118 | SENSOR MODULE WITH A DISPLACEMENT SENSOR AND A PRESSURE SENSOR IN A COMMON HOUSING - A sensor module comprises a housing in which a first displacement sensor and a first pressure sensor are arranged. The sensor module can have a second displacement sensor and a second pressure sensor. The module is being provided to monitor a coupling of a motor vehicle, for example a dual coupling of a lorry. | 2014-10-30 |
20140320119 | ROTATION SENSING APPARATUS - A sensor main body includes sensing elements, which sense rotation of a rotatable body. A first molded body is made of a resin material and covers the sensor main body. The sensor main body is placed at a distal end portion of the first molded body. A cover covers the distal end portion of the first molded body. An electrically conductive member is placed between the cover and the sensor main body and is electrically connected to a ground terminal of the sensor main body. | 2014-10-30 |
20140320120 | ROTATION ANGLE SENSOR - The rotational angle sensor for measuring the rotational angle of a shaft has two code disks, the first code disk of which is rotationally fixed to the shaft while the second code disk is held between the shaft and the housing by two spring groups. Each code disk is assigned to a sensor. The sensor of the first code disk generates a periodic rotational angle signal while the sensor which is assigned to the second code disk generates a coarse signal (U | 2014-10-30 |
20140320121 | MEASUREMENTS OF EARTH'S MAGNETIC FIELD INDOORS - There is provided an apparatus, comprising: at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to: perform a set of Earth's magnetic field, EMF, measurements inside a building, wherein each EMF measurement result represents at least one of a magnitude and a direction of the EMF in the building;
