Abstract: A deformable inductive device includes an elastomer material having at least one deformable electrode and a liquid magnetic core formed in the elastomer material and containing a magnetic liquid. Depending on the device's configuration, the deformable element may be embedded in, attached to, or in close proximity with the liquid magnetic core. In some embodiments, the deformable inductive device may be configured as an inductor, solenoid, or transformer and the deformable electrode is at least partially embedded in the liquid magnetic core, for instance. In another embodiment, the deformable inductive device may be configured as part of a wireless power transfer system which includes a coil and a magnetic backplane having the liquid magnetic core with the coil being attached to or in close proximity to the magnetic backplane.

Abstract: An electric field sensor having at least a first and second electrically conductive generally planar electrodes that are spaced apart from each other. A circuit is electrically connected to the electrodes which is configured to generate an output signal proportional to a time derivative of a varying electric field surrounding the electrodes. Optionally, three sets of spaced apart electrodes which are arranged perpendicularly relative to each other are used for three-dimensional measurements of the electric field.

Abstract: An antenna having an elongated housing open at one end and defining an interior chamber. A telescoping mast has a carrier attached at a first end and a flexible antenna attached at its other end. The carrier with the attached mast and antenna is movable between a storage position in which the carrier, mast, and antenna are contained within the interior chamber of the housing, and a deployed position in which the mast and attached antenna protrude outwardly from the housing. A spring is positioned between the carrier and the housing which urges the carrier towards its deployed position. A catch mechanism selectively holds the carrier in its stored position and, when released, releases the spring to move the antenna to its deployed position.
