Abstract: A bit-patterned media (BPM) magnetic recording disk has a cobalt (Co) alloy recording layer (RL), a ruthenium (Ru) containing underlayer (UL), and a noble metal film (NMF) as an interlayer between the RL and the UL. The RL is preferably oxide-free and is a Co alloy, like a CoPtCr alloy, with a hexagonal-close-packed (hcp) crystalline structure with its c-axis oriented substantially perpendicular to the plane of the RL. The NMF is an element from the Pt group (Pt, Pd, Rh, Ir) and Au, or an alloy of two or more of these elements, and has a thickness less than 3.0 nm, preferably between 0.3 and 1.0 nm. The NMF does not interrupt the epitaxial growth of the RL and has little to no effect on the distribution of the RL c-axis orientation. The NMF increases the coercivity (Hc) and perpendicular magnetic anisotropy constant (Ku) of the RL.

Abstract: An embodiment of the invention provides an apparatus that includes: a perpendicular magnetic recording medium including a substrate, a soft under layer above the substrate, a seed layer structure above the soft under layer, wherein the seed layer structure contains Ruthenium; and a magnetic recording layer above the seed layer structure.

Abstract: Wheelchair seat back mounting hardware permits the seat back to be mounted on various wheelchairs. The mounting hardware may be in the form of two-point mounting hardware that connects the seat back to the wheelchair and permits the seat back height to be adjusted independently of the mounting hardware location on the wheelchair.

Abstract: A seat assembly can be mounted on various wheelchair bases. The seat assembly enables the seat width and backrest width to be adjusted independently of each other. A backrest has a plurality of open slots, the number and orientation of which contributes to depth, width, and height adjustment of the backrest as well as angular adjustment of lateral supports to permit the backrest to conform to the anatomical curves of a user. A backrest foam assembly comprises multiple foam sections that are adapted to be positioned relative to each other and thereby vary the overall width of the assembly. A cover comprises multiple sections, each covering a foam section. A multi-position adjustable armrest assembly combines large-scale and small-scale adjustments, which provides a broad range of adjustment for the armrest and its position. A power recline mechanism with programmable shear reduction includes a dual rotary recline mechanism.

Abstract: A wheelchair has a seat frame and a back frame, the wheelchair being configured to tilt the seat frame from an initial position to a tilted position. The wheelchair includes a rear anti-tip wheel pivotally mounted for vertical articulation within a first range of motion. A means for limiting the vertical articulation to a second narrower range of motion in response to tilting of the seat frame is provided.
