  • Publication number: 20200143396
    Abstract: A system and method for survey weighting is disclosed. According to one embodiment, a method comprises selecting key survey variables (KSVs) related to the survey; selecting microdata sources that represent a target population; training models using the KSVs as key survey variables; and collecting out-of-sample predictions. The method further comprises making predictions using the models; averaging the predictions over the target population; and generating survey weights using a calibration estimator.

  • Publication number: 20070270944
    Abstract: The present invention provides valve prostheses adapted to be initially crimped in a narrow configuration suitable for catheterization through body ducts to a target location and adapted to be deployed by exerting substantially radial forces from within by means of a deployment device to a deployed state in the target location.

  • Publication number: 20070173932
    Abstract: An improved prosthetic mitral valve is provided having advantageous hemodynamic performance, nonthrombogenicity, and durability. The valve includes a valve body having an inflow annulus and an outflow annulus. Commissural attachment locations are disposed adjacent the outflow annulus. An anterior leaflet and a posterior leaflet of the valve are shaped differently from one another. The inflow annulus preferably is scalloped so as to have a saddle-shaped periphery having a pair of relatively high portions separated by a pair of relatively low portions. The anterior high portion preferably is vertically higher than the posterior high portion.

  • Patent number: 7215097
    Abstract: Two capacitors and at least one inductor are used to create an alternating magnetic field for use in electric motors. Charge leaving one capacitor passes through the inductor, creating a magnetic field, and is captured by the second capacitor. Energy is added to the second capacitor which is then discharged through the inductor to the first capacitor, creating a magnetic field of opposite polarity as that created by the first discharge.

  • Publication number: 20060259137
    Abstract: Methods and systems for minimally invasive replacement of a valve. The system includes a collapsible valve and anchoring structure. The valve assembly comprises a valve and anchoring structure for the valve, dimensioned to fit substantially within the valve sinus.

  • Patent number: 7037333
    Abstract: A tubular prosthetic semilunar or atrioventricular heart valve is formed by cutting flat, flexible leaflets according to a pattern. The valve is constructed by aligning the side edges of adjacent leaflets so that the leaflet inner faces engage each other, and then suturing the leaflets together with successive stitches along a fold line adjacent the side edges. The stitches are placed successively from a proximal in-flow end of each leaflet toward a distal out-flow end. During operation, when the leaflets open and close, the leaflets fold along the fold line. Distal tabs extend beyond the distal end of each leaflet. The successive stitches terminate proximal of the distal tab portion so that no locked stitches are placed along the distal portion of the fold line. The tab portions of adjacent leaflets are folded over each other and sewn together to form commissural attachment tabs.

  • Publication number: 20050278085
    Abstract: A control system includes a rate-damping loop that uses a calculated angle-of-attack error to non-linearly scale a rate-feedback signal so that at lower angle-of-attack (AOA) error values, an acceleration feedback term plays a greater role in pitch compensation, while at greater angle-of-attack error values, a rate-feedback term plays a greater role in the pitch compensation. In some embodiments, a control system and method of controlling an angle-of-attack of a moving body are provided. A signal representing an angle-of-attack error is non-linearly combined with a signal representing a rate-of-change of an estimated angle-of-attack to generate a non-linear rate-damping signal. The non-linear rate-damping signal is subtracted from the signal representing the angle-of-attack error to generate a signal to control one or more elements of the moving body.

  • Publication number: 20050098547
    Abstract: A method of cutting material for use in an implantable medical device employs a plotted laser cutting system. The laser cutting system is computer controlled and includes a laser combined with a motion system. The laser precisely cuts segments out of source material according to a predetermined pattern as designated by the computer. The segments are used in constructing implantable medical devices. The cutting energy of the laser is selected so that the cut edges of the segments are melted to discourage delamination or fraying, but communication of thermal energy into the segment beyond the edge is minimized to avoid damaging the segment adjacent the edge.
