摘要： An apparatus for correcting non-polarity and measuring displacement of an object using a search-coil type sensor includes a plurality of sensors that include respective housings having respective inner spaces, respective cores formed to be inserted into the inner spaces of the housings, and respective coils which are each wound around a portion of an outer circumferential surface of each of the housings, the portion corresponding to a position of each of the cores. The plurality of sensors are arranged in parallel with each other. A position of a core and a coil with respect to one housing differs from a position of a core and a coil with respect to another housing. An induced magnetic field is formed due to a distance change with respect to the object containing iron (Fe).

摘要： Inductive position sensors for sensing relative position (e.g., relative rotary position) between members are provided. In one example implementation, the inductive position sensor includes a transmit aerial having at least one transmit winding. The inductive position sensor can include a receive aerial having one or more receive windings. The inductive position sensor can include a coupling element operable to be disposed on the second member. The inductive position sensor can include processing circuitry configured to provide one or more signals indicative of the position of the first member relative to the second member based on current induced in the one or more receive windings resulting from an oscillating signal provided to the transmit winding. The inductive position sensor includes at least one electrostatic shield. The electrostatic shield can include a plurality of conductive traces arranged so that no current loops are formed in the electrostatic shield.

摘要： Systems and methods for sensor position measurements are provided. Aspects include receiving, through a first signal path, a first secondary signal from a first sensor and a built in test (BIT) signal, wherein the first signal path comprises a first multiplexer connected to a first filter, receiving, through a second signal path, a second secondary signal from the first sensor and the BIT signal, wherein the second signal path comprises a second multiplexer connected to a second filter, wherein the first signal path and the second signal path are connected to a third multiplexer, wherein the third multiplexer is connected to a first analog to digital converter (ADC), receiving, by a controller, an output signal from an output of the first ADC, and determining, by the controller, a position measurement for the first sensor based on the first secondary signal, the second secondary signal, and the BIT signal.

摘要： An inductive sensor device has a coil arrangement and sensor electronics for determining a longitudinal position of an at least partially electrically conductive and/or magnetically polarizable object moveable at a distance from a device end face along a device sensitive axis. The arrangement has a substantially planar exciting coil for producing an alternating magnetic field for inducing eddy currents and/or magnetic polarization in the object and a first substantially planar receiving coil substantially parallel to and overlapping the exciting coil. The coils are substantially parallel to the end face. The sensor electronics determine at least one parameter of an exciting coil electrical signal, which is variable owing to an inductive backward effect of the object, at least one parameter of a voltage inducible in the at least first receiving coil based on this effect, and the longitudinal position from the determined signal parameter and the determined voltage parameter.

摘要： A method for pressurizing and depressurizing a shock absorber of an aircraft. More specifically, it relates to a method in which an aircraft weight and ambient temperature are used to calculate a required pressurization level of a shock absorber. As such, the shock absorber may be pressurized to the correct level without applying an iterative approach, greatly reducing initialization time.
