Abstract: A technique is provided to coarse-class one or more customer characteristics used in a predictive model. A set of functions are used to represent partition points of the customer characteristic into smaller classes. Each of the final classes of the customer characteristic is represented separately in the predictive model.

Abstract: A throttling valve assembly has an outer housing that is sealed. An actuator is connected to a pressure balanced shaft that extends into the housing to operate a plurality of linkages that can rotate blades in tandem. With the surrounding housing sealed, the shaft penetrations of the blade support shafts no longer need seals or a purge system to supply process gas during times of reduced pressure in situations with the blades nearly closed. A pressure equalization system has balance passages internal to the housing to allow flow from higher pressure zones to lower pressure zone of the process gas so as to avoid creation of a condition that can draw air into any zones of reduced pressure in the housing.

Abstract: A technique for selecting portions of a multi-resolution medical image data set to be stored and the portions of the multi-resolution medical image data set to be discarded in order to reduce the overall amount of image data that is stored for each image data set. The selection is based on the clinical purpose for obtaining the medical image data. The clinical purpose for obtaining the medical image is used to define regions of interest in the medical image. At each resolution level of the multi-resolution medical image data set, the regions of interest are stored at the full resolution, while the remaining portions of the medical image are stored at a lesser resolution. A three-dimensional bit mask of the regions of interest is produced from a segmentation of the regions of interest. The segmentation list and the multi-resolution medical image data set are decomposed into multiple resolution levels. Each resolution level has a low frequency component and several high frequency components.

Abstract: A two stroke engine of a particular configuration can have its power output increased by running bigger pistons and using ports in the piston skirt through which to conduct compressed air within the skirt through short passages in the cylinder housing that conduct the air from within the skirt to above the piston. As a result a larger piston can be used for the same spacing and opening size in the block to save the need to redesign the block and the crankshaft. A position adjuster for the piston moves it axially without rotation of the piston ports out of alignment with inlet ports in the housing. The piston rod is held in the crosshead using a flat to prevent rotation while an adjuster nut that is turned creates axial movement in the piston rod with a lock nut securing the final piston position.

Furthermore, storage and/or display of this information may allow for the creation of resistance distribution histograms for modeling of one or more memory arrays.

Abstract: The present techniques provide methods and systems reading a data bit of interest on an optical data disc with a reduced error rate. The data bit estimation may be improved by reducing deterministic noise resulting from an optical reader system and/or the optical data disc. The reader may adjust the position of a detector to detect light scattered from the disc based on parameters of known noise sources. In one embodiment, the detector may be moved vertically in relation to the data bit of interest on the optical disc. In another embodiment, more than one detector may be used to detect light scattered from a data bit of interest. In embodiments, the positioning of the detector(s) may be based on system or disc parameters, and the detected scatterings may provide a data reading, improved for an optical return from a present micro-hologram.

The non-split unitary front bearing can include pockets in its central bore that can allow a spherical section of an actuator arm to be inserted into the bearing. The spherical section can include radially recessed areas to facilitate the insertion into the bearing. The jaws can be retained to the actuator arms through the use of a quick-release assembly. The quick-release assembly allows the jaws to easily and quickly be changed to allow the chuck to grasp different workpieces.

Abstract: A magnetic cell structure including a nonmagnetic filament contact, and methods of fabricating the structure are provided. The magnetic cell structure includes a free layer, a pinned layer, an insulative layer between the free and pinned layers, and a nonmagnetic filament contact in the insulative layer which electrically connects the free and pinned layers. The nonmagnetic filament contact is formed from a nonmagnetic source layer, also between the free and pinned layers. The filament contact directs a programming current through the magnetic cell structure such that the cross sectional area of the programming current in the free layer is less than the cross section of the structure. The decrease in the cross sectional area of the programming current in the free layer enables a lower programming current to reach a critical switching current density in the free layer and switch the magnetization of the free layer, programming the magnetic cell.

Abstract: Techniques for controlling a driver to reduce data dependent noise, such as simultaneous switching effects and cross-talk effects. A plurality of drivers may each receive a data segment to transmit and a plurality of data segments that other drivers will transmit. A driver controller may adjust the time at which the data segment is transmitted in response to the plurality of data segments that the other drivers will transmit. The adjustment may compensate for simultaneous switching noise and cross-talk by, for example, delaying the transmission of a data segment or changing the slew rate of the signal carrying the data segment.
