摘要： A ferrofluidic electromagnetic power supply firmly attached to an agitating object, such as the interior of a vehicular tire generates electric current in an electrical coil deposited between and firmly attached to an hermetically sealed housing made of non-magnetic material partially filled with ferrofluid and a permanent magnet axially polarized. The ferrofluid and the permanent magnet form a magnetic circuit extending from the ferrofluid through the coil to the permanent magnet and back to the ferrofluid. Agitation of the power supply will cause dislocation of the magnetized ferrofluid within the sealed housing causing induction in the electrical coil.

摘要： A differential transformer is provided comprising an elongated secondary winding of uniform turn density. First and second transformer primary windings are wound about the secondary winding. The primary windings lie generally in parallel spaced apart planes which cut the axis of the secondary winding at an angle other than 90.degree.. A core of magnetic material is movable linearly along a path parallel to the secondary winding axis and serves to couple the primary and secondary windings. The primary windings are connected to AC sources which are 90.degree. out of phase with each other.

摘要： A ferrofluidic electrical power generator installed within an agitating object, such as the interior of a vehicular tire generates electrical current in an electrical winding wound about an elongated permanent magnet. The winding is surrounded by sealed container made of non-magnetic material, partially filled with magnetized ferrofluid. The permanent magnet and the magnetized ferrofluid form a magnetic circuit surrounded by the electrical winding. Rotation and horizontal velocity of the tire will agitate the magnetized ferrofluid within the sealed container causing cyclic variations in the distribution of the magnetized ferrofluid causing variation in the magnetic flux density, thus, induction in the electrical winding.

摘要： A rotary variable differential transformer is provided comprising a pair of RVDT units disposed along a common shaft. A third RVDT is positioned along the shaft between the two units. The third RVDT comprises two pairs of secondary coils each pair being connected in series opposition. One of the coil pairs is connected to the secondary coils of one of the RVDT units and the other pair is connected to the secondary coils of the other RVDT unit. The third RVDT unit does not contain a primary and its secondary coils are excited only by the leakage flux from the other units.

摘要： A shaft angular position sensor having a DC output voltage has a magnetic housing into which are mounted a Hall effect device, a bobbin-winding assembly and a rotor. The bobbin-winding assembly is a hollow cylindrical coil form made of non-magnetic material about which are wound two excitation coils connected in series opposition. An elongated magnetic core is disposed for rotation within the hollow bobbin. The core is an axial section of a magnetic cylinder which serves to direct two opposing DC magnetic flux flows through the Hall effect device. The output voltage generated by the Hall effect device is indicative of the angular position of the magnetic core relative to the bobbin winding assembly when a DC voltage is applied to the coils.
