Abstract: An optical modulator includes optical material(s) and first and second differential electrode pairs. The optical material(s) exhibit an electro-optic effect and include lithium. The optical material(s) include first and second waveguides and first and second slab portions adjoining the first and second waveguides. The first differential electrode pair has electrodes arranged on opposing sides of the first waveguide. The second differential electrode pair has electrodes arranged on opposing sides of the second waveguide. The negative electrodes are arranged on distal sides of the waveguide relative to the other waveguide. The positive electrodes are arranged on proximal sides of waveguide relative to the other waveguide. The first and second waveguides, the first and second slab portions, and the first and second differential electrode pairs reside on a substrate structure. No portion of the first slab portion is between the first or second differential electrode pair and the substrate structure.

Abstract: A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft. The compartment may be sized to receive the prosthetic heart valve. The inner shaft and the distal sheath may be movable relative to one another. A spine may extend along the outer shaft, the spine biasing the outer shaft so that the outer shaft tends to bend in a pre-determined direction.

Abstract: A method for locally creating effectively homogeneous or “clean” magnetic field gradients (of high uniformity) for imaging (with NMR, MRI, or spectroscopic MRI) both in in-situ and ex-situ systems with high degrees of inhomogeneous field strength.

Abstract: A method for locally creating effectively homogeneous or “clean” magnetic field gradients (of high uniformity) for imaging (with NMR, MRI, or spectroscopic MRI) both in in-situ and ex-situ systems with high degrees of inhomogeneous field strength. The method of imaging comprises: a) providing a functional approximation of an inhomogeneous static magnetic field strength B0 (r) at a spatial position r; b) providing a temporal functional approximation of Gshim(t) with i basis functions and j variables for each basis function, resulting in vij variables; c) providing a measured value ?, which is an temporally accumulated dephasing due to the inhomogeneities of B0 (r); and d) minimizing a difference in the local dephasing angle (I) by varying the vij variables to form a set of minimized vij variables. The method requires calibration of the static fields prior to minimization, but may thereafter he implemented without such calibration, may he used in open or closed systems, and potentially portable systems.

Abstract: A trim piece cover member for a refrigerator door is snap-fittingly secured to and extends along substantially an entire length of a trim piece to hide a plurality of mechanical fasteners. The trim piece includes a channel that extends longitudinally along an outer exposed surface. The channel includes a base portion, as well as first and second opposing side portions. The plurality of mechanical fasteners extend through the base portion and into the refrigerator door. The cover includes a generally planer surface portion from which extend first and second side walls that terminate in corresponding tab members which are snap-fittingly received in recesses of the channel.
