    摘要: A generator providing both tachometer and synchro outputs and comprising a magnetic stator and a corresponding armature structure. The generator stator structure produces a composite magnetic field of both constant (DC) and alternating (AC) flux. The rotor directs the composite flux field through a plurality of sensing coils, each producing a signal from the sensed composite magnetic field and rotor motion, and which coil signal is separated into separate signal components. The components are processed to produce a synchro output which preferrably has standard Hall-effect equivalent signals, as well as providing a tachometer output voltage proportional to the rotor rotational velocity and direction.

    摘要: Magnetic field detectors include a proof mass suspended by deformable arms similar to a three dimensional accelerometer. The magnetic field detectors further include magnetically sensitive material present on the proof mass and/or deformable arms to cause movement of the proof mass and/or deformable arms when in the presence of a magnetic field. This movement is converted to an electrical signal and that electrical signal is compared to a reference to determine if a magnetic field of interest is present. The magnetic field detector may be included within an implantable medical device, and when the magnetic field detector indicates that a magnetic field of an MRI scanner is present, the implantable medical device may switch to an MRI mode of operation. The device may also switch back to a normal mode of operation once the MRI scanner is no longer detected such as after a predefined amount of time.

    摘要: A rotor for an electromagnetic indicator comprises a flat circular disk made of thin, pliable, nonmagnetic material. The disk has integral tabs extending out of diametrically opposite edges and a rib extends diametrically of the disk to outer ends of the tabs. The rib and tabs define T-shaped trunnions which engage in T-shaped slots in respective sides of a rotary magnet, and a journal block. The disk is fabricated from a single flat sheet having flat tabs extending outwardly of opposite edges. A V-shaped groove is made in the sheet extending centrally across the disk and tabs. Opposite sides of the groove are then brought together to form the rib with T-shaped trunnions at opposite edges of the disk.

    摘要: A magnetic sensor includes a thin deformable membrane made of a conductive material forming a first plate of a capacitor which conducts an electric current therethrough. A second capacitor plate of the capacitor includes a doped region of a semiconductor substrate. A layer of a gaseous dielectric separates the two plates. The membrane deforms due to the effect of the Lorentz force generated by a magnetic field lying in the plane of the membrane and perpendicular to the lines of current being conducted therethrough. In addition, a process for fabricating this magnetic sensor is also provided as well as a device for measuring a magnetic field using the magnetic sensor.

The calibration phase calculating unit is configured to calculate a calibration phase of the resolver based on the reference pulse signal from the reference pulse generation unit and the digital output signal from the RDC.

    摘要: An angular position sensor for determining the relative angular position of two relatively rotatable ferromagnetic coaxial components, such as a rotor and stator. The components have the same number of regularly distributed teeth and the teeth in one component are separated by an air gap from the teeth in the other component. A plurality of coils are connected in series with each other and are disposed around the teeth in one of the components and correspond in number to the number of associated teeth. An electric excitation signal having a measurable constant electrical characteristic is fed to the plurality of coils from a source. The characteristic is modulatable in response to variations in the magnetic reluctance of the air gap effected by changes in the relative angular position between the two components. Electronic circuitry is connected to coils for measuring the modulation of the characteristics to determine the relative angular position of the components. In angular position determination apparatus comprising a plurality of angular position sensors, mechanical connections are provided between the rotors on the one hand and the stators on the other. The angular displacement between the rotor and stator teeth differs for each sensor, the difference generally being a multiple of the quotient of 2.pi. by the number of teeth and the number of sensors. The sensor is well adapted for use in the robotics field.
