Abstract: A downhole tool has a directional pad that contacts a wellbore wall at a pad contact location and a drill bit with at least one active cutting element that contacts the wellbore wall at a cutting element contact location. A contact distance between the pad contact location and the cutting element contact location being 3 in. (7.6 cm) or less.

Abstract: Systems and methods for de-identification of medical images can be applied to medical images acquired using various techniques. A 3D medical image can be analyzed to generate an image mask that partitions the image into a foreground region and a background region. From the image mask, a “skin surface” can be reconstructed based on the boundary between the foreground region and the background region. The image mask can be modified, e.g., by moving a randomly-selected subset of the voxels from the foreground region to the background region so that the shape of the skin surface is altered, thus obscuring patient-identifying features. The original medical image can be modified by changing the intensity of voxels in the background region while preserving the original intensity of voxels in the foreground region.

Abstract: An axial field motor and a method of assembling the motor are provided. The hard disk drive includes a spindle motor having a fluid dynamic bearing (FDB) motor hub, a hard disk drive housing and a base insert. The hard disk drive housing houses the spindle motor therewithin and has an upper housing and a base, the base including a first material. The base insert has ferromagnetic properties, includes a second material and has a flat circular bottom portion and an outer circumferential vertical portion. The flat circular bottom portion of the base insert is located between the FDB motor hub and the base to enhance yield strength therebetween and a bottom portion of the FDB motor hub is surrounded by the outer circumferential vertical portion of the base insert to generate preload for the FDB motor hub.

Abstract: According to an embodiment of the present invention, a data storage device comprising a motor having a stator is disclosed. The stator may include a substrate having a first surface and a second surface opposite to the first surface; and a n-phase winding arrangement having n phase windings; wherein each phase winding comprises m flat fractional-pitch coils arranged on the first surface of the substrate such that the coils are spaced apart uniformly along a closed loop and connected in series; wherein each coil together with an angular section of the substrate between the coil and an adjacent coil of the same phase winding defines a stator pole-pair; and wherein m is an integer larger than 1.
