Abstract: A drive tumbler comprises a hub having attached thereto a plurality of replaceable rim segments. The rim segments are supported by a plurality of raised blocks that are formed integral with the hub and serve to absorb the shear forces to which the tumbler is subject during operation.

Abstract: A data processing system facilitates virtual machine migration with direct physical access control. The illustrative data processing system comprises a software-programmable trap control associated with hardware registers of a computer that selectively vectors execution control of a virtual machine (VM) between a host and a guest. The data processing system further comprises a logic which is configured for execution on the computer that programs the trap control to enable the virtual machine to directly access the hardware registers when the virtual machine is not migrated and to revoke direct access of the hardware registers in preparation for virtual machine migration.

Abstract: An mobility assistance device providing support for a user on a bed or similar furniture is disclosed. The mobility assistance device may include a support member that can be coupled to a piece of furniture and a support handle that is movable in a substantially vertical direction relative to the support member. The support handle is movable from an operating position to a stowed position. A locking mechanism may secure the support handle in the raised operating position.

Abstract: A device for assisting a user in getting into and out of sitting and prone positions on a piece of furniture, like a bed, which has a large base to fit between the mattress and box springs of a bed and that includes a receiving portion and an adjustable handle for the user to grasp while getting into an out of bed and while adjusting positions in the bed.

Abstract: Provided herein are intracorneal inlays for correcting vision impairments by altering the shape of the anterior corneal surface. The physical design of the inlay to induce the desired change of the anterior corneal surface includes consideration of the biomechanical response of the corneal tissue to the physical shape of the inlay. This biomechanical response can differ depending on the thickness, diameter, and profile of the inlay. In one embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an “effect” zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the “effect” zone. In another embodiment, small diameter inlays are provided that induce “effect” zones on the anterior corneal surface that are much larger in diameter than the inlays.

Abstract: Methods and systems for conducting liner drilling and subsequent completion of the drilled section by cementing and anchoring the liner into place. The methods and systems prevent the liner from being cemented in in a bent or corkscrewed configuration. Additionally, there are no exterior components associated with the liner during drilling so as to allow relatively unrestricted return of drilling mud and cuttings.

Abstract: A drilling assembly supports a liner for making a wellbore. The BHA comprises a pilot bit and a reamer above it that is larger in diameter than the suspended liner. If the BHA needs to be pulled out, the reamer is brought into contact with the liner and a latch mechanism between the two engages as another latch that had held the reamer bit to the BHA is released. The reamer bit stays with the liner as the BHA is pulled and later reinserted. On the way in the BHA latches to the reamer bit which then unlatches from the liner bottom. Preferably, splines and a shoulder on the BHA are used to drive the reamer bit as opposed to any power being transmitted through the latch between the BHA and the reamer bit. However, the latch mechanism between the BHA and the reamer bit could also provide torque and weight on bit for drilling operations. The process may be repeated.

Abstract: An adjustable mobility assistance device providing support for a user on a bed or similar furniture is disclosed. The mobility assistance device may include a base that can fit under a mattress and a support rail that extends upright relative to the base. The longitudinal dimension of the support rail may be adjustable independent of the base. The support rail may be pivotally coupled to the base so that it can be disposed in an upright configuration or a lowered configuration while the base is under a mattress.

Abstract: A mobility assistance device for providing support to a user is disclosed. The mobility assistance device may include a handle having a plurality of rungs to be grasped by a user. The handle may be pivoted to various support positions as desired.

Abstract: Provided herein are small diameter inlays for correcting vision impairments by altering the shape of the anterior corneal surface. In an embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an “effective” zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the “effect” zone. In another embodiment, small diameter inlays are provided that induce effective optical zones on the anterior corneal surface that are much larger in diameter than the inlays. The increase in the effective optical zone, due at least in part to a draping effect, allows an inlay to produce a much larger clinical effect on a patient's vision than the diameter of the inlay.

Abstract: An assist device to help a user move from a sitting or reclined position to an upright position, and vice versa, with a functional tray. The assist device includes a base, a receiver, a handle, and a tray. The base may be positioned between a mattress and a box spring, or a couch frame and a couch cushion, or the like. The handle includes various gripping sections. The handle pivotably couples to the receiver and the tray rotatably couples to the handle. The tray moves from a closed position to an open position, or a usable position, to allow the user to place objects thereon, or to use the tray for any other purpose.

Abstract: Described herein are designs of intracorneal inlays to produce desired shapes of the cornea's anterior surface for correcting vision impairments. In an exemplarily embodiment, a thickness profile is defined by a difference between a desired post-operative anterior corneal surface that corrects a patient's vision impairment and the patient's pre-operative anterior corneal surface. An inlay is then dimensioned to substantially have the same thickness profile. When implanted in the patient's cornea, the thickness profile of the inlay is substantially transferred to the anterior corneal surface through the intervening corneal tissue, thereby producing the desired post-operative anterior corneal surface.
