Abstract: A computer-implemented method is provided of finding one or more data items that match one or more defined criteria in a dataset. The method comprises identifying data snippets of the dataset using a set of one or more attention rules; categorizing the identified data snippets using fuzzy matching by assigning them to buckets such that each bucket contains data snippets that are similar to another according to a similarity measure; classifying buckets containing data snippets having more than a threshold number of the true positive data items as true positive buckets and remaining buckets as false positive buckets; calculating culling rules based on the true positive buckets and the false positive buckets, and using the culling rules to remove the false positive data items from the true positive buckets.

Abstract: A device for protection of a body from radiation includes at least one flexible garment. Each section of the flexible garment is configured to shield a region of a surface of the body. Each section complementarily attenuates self-shielding by internal structure between the region and an interior region of the body such that radiation at the interior region is attenuated to a predefined attenuation level.

Abstract: A magnetoresistive sensor having a magnetically stable free layer fabricated from a material having a positive magnetostriction such as a Co—Fe—B alloy. Although the free layer is fabricated from a material that has a positive magnetostriction, which would ordinarily make the free layer unstable, the magnetization of the free layer remains stable because of an induced magnetic anisotropy that has an easy axis of magnetization oriented parallel to the Air-bearing Surface (ABS). This magnetic anisotropy of the free layer is induced by an anisotropic texturing of the surface of the free layer. The resulting anisotropic surface texture is produced by an ion milling process that utilizes an ion beam directed at an acute angle relative to the normal to the surface of the wafer whereon the sensor is fabricated while the wafer is held on a stationary chuck.

Abstract: An embodiment of the invention is a method for fabricating a head for perpendicular recording with self-aligning side shields. The voids where the side shields will be formed are milled into the layer of material for the pole tip to achieve self-alignment. A mask is patterned with openings defining initial shape of the pole piece tip nearest the air-bearing surface including the width and the point at which the pole tip widens out. A film of soft magnetic material to form the side shields is deposited over the wafer. A chemical-mechanical-polishing process is preferably used to remove the mask and the material deposited on it. A new mask is patterned over the predetermined area for the final shape of the pole tip and the side shields. The excess side shield material and pole tip material outside of the mask is then removed.

Abstract: Methods and apparatus provide a magnetic head that includes a magnetoresistive read sensor disposed between a first magnetic shield and a second magnetic shield. The second magnetic shield is configured to reduce effects on the read sensor due to unevenness in a topography of the read sensor.

Abstract: A system of tracking objects through a service process at a service shop comprises a computer network configured to track movement of tagged service objects from physical location to physical location within the service shop. The computer network comprises tag readers with antennae configured to receive transmissions from tags encoded with identifiers and connected to associated tagged service objects. The tag readers transmit identifiers obtained from the tag transmissions together with an indication as to which antenna received each transmission. Servers receive the identifiers transmitted from the tag readers and determine, based at least on the identifiers and which tag reader antenna received the transmissions, which physical location each service object associated with the received identifiers occupies. Client workstations generate a visual map of physical locations together with summary status information showing which service objects occupy the displayed physical locations.

Abstract: A magnetoresistive sensor having a self biased free layer. The free layer is constructed upon an underlayer that has been treated by a surface texturing process that configures the underlayer with an anisotropic roughness that induces a magnetic anisotropy in the free layer. The treated layer underlying the free layer can be a spacer layer sandwiched between the free layer and pinned layer or can be a separate underlayer formed opposite the spacer layer. Alternatively, the texturing of an underlayer can be used to induce a magnetic anisotropy in a bias layer that is separated from the free layer by an orthogonal coupling layer. This self biasing of the free layer induced by texturing can also be used in conjunction with biasing from a hard-bias structure.

Abstract: A read head has a bottom lead made of material that is relatively polish resistant and a top lead layer that polishes down more easily than the bottom layer. With this structure, when the layers are deposited and then polished down, the top layer recesses away from the sensor (and bottom lead layer) in a controlled fashion, providing an acceptable lead structure that reduces the mismatch between the read head physical read width and magnetic read width.

Abstract: A magnetic head having an improved read head structure. The read head includes a free magnetic layer with hard bias elements disposed proximate its ends, where the hard bias elements include an improved hard bias magnetic grain structure. This is accomplished by fabricating the hard bias element as a bilayer structure having a first hard bias sublayer, a nonmagnetic midlayer and a second hard bias sublayer. The midlayer is preferably composed of a nonmagnetic material such as chromium, and the hard bias sublayers are composed of a magnetic material such as CoPtCr. Each sublayer is formed with its own magnetic grains, and because there are two sublayers, the hard bias element is fabricated with approximately twice the number of magnetic grains as the prior art single layer hard bias element.

Abstract: A magnetic write head for us in perpendicular magnetic recording tapered trailing shield design for improved write flux, and field gradient performance.

Abstract: Magnetic data storage devices use read/write heads to transfer data between the magnetic storage medium and the rest of the system. The read head is constructed with a magnetic layer called a free layer whose magnetic axis rotates based upon external magnetic influences of the magnetic storage medium. The free layer is biased into a predetermined magnetic orientation with the magnetic influence of a layer called a hard bias layer. Orientation of magnetic axes within the hard bias layer is desired. This document describes a hard bias layer whose magnetization exhibits uniaxial magnetic anisotropy.

Abstract: A magnetic sensor is provided, having two bias layers separated by a decoupling layer to eliminate exchange coupling between the bias layers. The two bias layers may have differing coercivities, such that the biases provided by the bias layers to the free layer are independently adjustable. The grain structures of the two bias layers may be substantially decorrelated by the decoupling layer.

Abstract: The invention is a magnetic transducer with separated read and write heads for perpendicular recording. The write head has a trailing shield that extends from the return pole piece toward the main pole piece to form the write gap at the air-bearing surface. One embodiment of the trailing shield is a two part structure with a pedestal and a much smaller tip that confronts the main pole piece at the gap. In one embodiment a sink of non-magnetic, electrically conductive material is disposed in the separation gap between the read head and the flux bearing pole piece. The sink is preferably made of copper and does not extend to the ABS.
