Abstract: Disclosed herein are embodiments of devices, systems, and methods for converting magnetic energy into one or more other forms of energy, or stated otherwise, for deriving power in a desired format from magnetic energy. In one system, energy provided by a magnetic field of a magnetic source is converted into rotational energy of one or more components of a system. The system can include a magnetic source that is coupled with a rotational component so as to instigate and/or maintain rotation of the component, and is decoupled from the component due at least in part to torque provided by another magnetic source.

Abstract: A sealing device for downhole use, one of which is for casing, when drilling with casing, which allows the casing to be closed off if the bottom hole assembly needs to come out for any reason. In one embodiment, the internal packer is triggered to set in a variety of ways upon removal of the bottom hole assembly. It can be drilled out when the new bottom hole assembly is run in later. In an alternative design, a flapper can be used that is held open for the initial insertion of the bottom hole assembly and is released to spring shut upon removal of the assembly. Multiple flappers or packers or other types of closure devices are envisioned to allow removal of the bottom hole assembly more than once and still retain blowout protection on each removal of the bottom hole assembly. A variety of applications are contemplated some of which are perforation, side tracking, fracturing, and gravel packing, to name a few examples.

Abstract: A collapsible walking device that can be disposed in an operative (open) configuration and a storage (closed) configuration. The open, operative configuration of the walking device provides a structure to aid a user in walking or standing. The closed, storage configuration allows for easy and convenient storage and transport of the walking device. The collapsible walking device can be transitioned from the operative configuration to the storage configuration in one motion. The walking device includes four support legs that extend to the ground from adjacent two handles.

Abstract: A compressible wheel tip for a walking aid that restricts rolling when a force is applied down on the walking aid. The tip may have a compressible wheel configured to deform under an applied pressure and thereby restrict shifting or rolling of the wheel. The compressible wheel may include rigid spokes and a compressible material forming an arcuate perimeter between the spokes to define a wheel shape. The compressible material may be a resilient elastomeric material adapted to deform under an applied force and return to its original shape when the force is no longer applied. The spokes may be formed of plastic or metal, or formed of the same material as the spokes and structured to better resist deformation.

Abstract: Power consumption of a group of computer systems is managed based on a maximum power consumption for the group. A power budget is determined from the power consumption of each computer system and the maximum power consumption for the group. The power budget identifies a power cap for each computer system in the group. The power caps in the power budget are distributed to the computer systems in the group.

Abstract: A management workstation has an interface for receiving notifications of data-center facilities infrastructure events. A manager determines emergency power settings for managed computing resources in response to the notifications. The settings are then communicated to the resources.

Abstract: A collapsible mobility assistance device which may be configured in an operable configuration and a storage configuration. The device may be configured such that each individual component is planar, which may allow the device to be packaged, stored, and/or shipped in minimally sized containers.

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: A walking cane that can be stored in a novel manner is provided. The walking cane may include a non-articulating handle portion and a shaft portion extending from the handle portion. The handle portion is shaped in such a manner as to allow the walking cane to be self-standing when it is inverted and the handle portion is placed on the ground.

Abstract: A removable shock absorbing tip for a walking aid. The tip may be comprised of a shaft engaging member for connecting the tip to the shaft of a walking aid, an outer shell, and a biasing member. The biasing member may disposed within the outer shell in abutment with the shaft engaging member. The biasing member may also be disposed around the shaft engaging member and in abutment with the outer shell. The biasing member may be a spring, a fluid-filled cushion, or a member formed of elastomeric material. The outer shell may be formed of transparent or translucent material to permit the biasing member to be visible to a user for ease of identification.

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: 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 corneal implant having an aspheric surface for modifying the cornea curvature and altering the corneal refractive power. The corneal implant has a lens body formed of an optically clear bio-compatible material, preferably with an index of refraction substantially similar to that of human corneal tissue (1.376). The aspheric surface is comprised of a continuous aspheric surface from the apex of the implant to beveled surface. The beveled surface, positioned near the outer diameter of the implant, is used to reduce the thickness of the aspheric surface on the periphery of the lens to the outer diameter edge. The body of the implant has a diameter between about 2.0 mm and 7.0 mm and a thickness less than about 0.150 mm.
