| 7218067 | Magnetic actuator drive for actuation and resetting of magnetic actuation materials A magnetic actuator is provided including a magnetic field-actuated material and a plurality of interconnected electrically conducting coils, each coil including a number of wire turns arranged relative to at least one other coil to produce at the magnetic field-act... | 05/15/2007 |
| 7061356 | Controllable transformer A controllable transformer device comprising a body of a magnetic material, a primary winding wound round the body about a first axis, a secondary winding wound round the body about a second axis at right angles to the first axis, and a control winding wound round t... | 06/13/2006 |
| 7042310 | High-pass branch of a frequency separating filter for ADSL systems The invention relates to a high-pass branch (7) of a frequency separating filter for ADSL systems comprising inductive components (11, 14) which dispose of magnet cores made of a soft magnetic amorphous or nanocrystalline. As a result, frequency separa... | 05/09/2006 |
| 4987390 | Superconducting reversible variable inductor A superconducting reversible variable inductor of this invention comprises: a core made of a Type II superconductor having a reversible magnetic permeability variation range in which the magnetic permeability varies reversibly with respect to a variation ... | 01/22/1991 |
| 4902987 | Inductive modulator system A magnetic induction modulation and frequency multiplication system includes three toroidal coils physically mounted close to one another to provide magnetic flux coupling between them. One of the coils is supplied with a relatively high frequency carrier... | 02/20/1990 |
| 4429288 | Apparatus and method for modulation of a curl-free magnetic vector potential field Apparatus for producing and modulating a magnetic vector potential field having a substantially curl-free component. Detection and demodulation of the curl-free component of the magnetic vector potential field using a Josephson junction device are describ... | 01/31/1984 |
