Abstract: Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.

Abstract: An ankle prosthesis can have a base and an upper hinge component that is pivotably attached to the base about an axis. First and second biasing elements can bias the upper hinge component in first and second rotational directions, respectively. At least one selectively extendable and retractable locking element can extend from one of the base and the upper hinge component and engage the other of the base and the upper hinge component to limit the pivotable movement of the upper hinge component.

Abstract: Methods and systems for an automated micro-scheduler testing framework that allows tests to be automatically scheduled or rescheduled based on information such as results of previously-executed tests or other external information are provided. In large-scale development environments, where individual changes to a code repository cannot be specifically fully tested due to scalability and resource issues, micro-scheduler servers may be configured and designed to automatically identify target tests and request that the target tests be executed by a continuous integration system to automatically identify and resolve breakages introduced into a codebase managed by the continuous build system in a large-scale environment.

Abstract: A wheelchair having a frame and a drive wheel coupled to the frame. The drive wheel rotates relative to the frame about a first axis of rotation. A first push rim is coupled to the frame. The first push rim rotates relative to the frame about a second axis of rotation that extends substantially parallel to the first axis of rotation. A second push rim is coupled to the frame. The second push rim rotates relative to the frame about a third axis of rotation that extends substantially parallel to the first axis of rotation. A transmission transmits rotation of each of the first and second push rims to the drive wheel. Movement of the first push rim by a first arc length causes the drive wheel to rotate by a first angular displacement, and movement of the second push rim by the first arc length causes the drive wheel to rotate by a second angular displacement that is greater than the first angular displacement.

Abstract: An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The exercise machine may include a compact and safe counterbalancing gas spring mechanism that tends to move the exercise device away from the exerciser, and that requires a force to be applied to move an exercise device down towards the exerciser. The exercise machine may include an exercise device that is rotatable along a vertical axis, and may be coupled to an adjustable monitor for a wide range of uses. The exercise machine may be used by a exerciser lying supine, sitting in a chair or wheelchair, or standing in front of or adjacent the exercise machine.

Abstract: A manual wheelchair including a collapsible frame with at least one brace connected to at least one of the frame members. A drive wheel axel extends along a first axis of rotation and engages a drive wheel, the first brace, and a portion of a transmission. A push rim axel extends along a second axis of rotation and engages a push rim wheel, the second brace, and a portion of the transmission, which transmits rotation of the push rim to rotation of the drive wheel. The at least one brace is configured to release the at least one of the frame members to collapse the wheelchair.

Abstract: An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The mobile base has caster wheels and can be positioned from either side of a bed so as to extend partially under a bed with the upright support located on one side of the bed and the exercise device suspended over the bed in a position accessible by a patient lying supine in the bed for performing exercise. An anchoring system resists movement of the base for stability when exercise is performed.

Abstract: A manual wheelchair including a collapsible frame having a first lateral member that is connected to first and second braces at their respective first ends. A drive wheel axle extends along a first axis of rotation and engages a drive wheel, the first brace, and a portion of a transmission. A push rim axle extends along a second axis of rotation and engages a push rim wheel, the second brace, and a portion of the transmission, which transmits rotation of the push rim to rotation of the drive wheel. The collapsible frame additionally includes a second lateral member that is connected to the first and second braces as their respective second ends. The first and second braces are configured to release the second lateral member to collapse the manual wheelchair.
