Abstract: A system for measuring magnetic field gradients comprising a multi-bay support structure with a series of raised contact shoulders separated from each other by voids. An optical fiber is spaced along the length of the multi-cell support structure and traverses all the raised contact points and voids. The optical fiber has a plurality of Fiber Bragg gratings (FBGs) spaced lengthwise, each FBG suspended in a void. In addition, a plurality of ferromagnetic members are strung onto the optical fiber, each suspended in a void. Magnetic field gradients act on the ferromagnetic member to create localized tension in the optical fiber. The FBG's refractive indices are monitored, tension is calculated therefrom, and the tension is correlated to the magnetic field gradient. This greatly simplifies mechanical, optical, electronic and computational complexity and is bay suited for any FOSS array for measuring magnetic fields using many dense measurement points.

Abstract: A method of fabricating a multiferroic antenna element may include providing a electroelastic substrate to transform mechanical oscillations into an acoustic wave, providing a resonator assembly on a surface of the electroelastic substrate where the resonator assembly includes a plurality of magnetoelastic resonators that transform an electromagnetic wave into mechanical oscillations corresponding to a frequency of the electromagnetic wave, and providing an interdigitated electrode assembly at a portion of the electroelastic substrate to convert the acoustic wave into an electrical signal preserving information associated with the frequency of the electromagnetic wave.

Abstract: An expandable mechanical distension device for hollow organ growth comprising a spring stent structure to elongate hollow organs by mechanical expansion. The device preferably expands radially to engage the internal walls of the hollow organ segment at a desired treatment location and expands axially to enlarge the hollow organ segment. The distension device may be configured for the treatment of patients with insufficient hollow viscus, e.g. hollow organ deficiency such as short gut syndrome, to enhance their gut length by mechanical force.
