Abstract: A suture anchor having a conical surface and a bore in which an end of an insertion tool is inserted. The insertion end of the insertion tool is made of material having elastic properties. The bore and base of the suture anchor are angled with respect to the central axis of the suture anchor and preferably are parallel to each other. During insertion, the suture anchor is reoriented to fit into the hole, thereby bending the elastic end of the insertion tool. When the suture anchor is within cancellous bone tissue, the elastic properties of the insertion tool deploys the suture anchor to an orientation in which the suture anchor cannot fit through the bone hole, thereby firmly anchoring the suture anchor in the human bone.

Abstract: One embodiment of a lateral roll simulating assembly is provided which is adapted to attach to existing rowing exercise machines. It permits the user to experience various levels of physiological disequilibrium when a lack of proper balance control induces a sideways tipping action during a rowing workout. This facilitates the desirable and advantageous development of correct proprioceptive balance response using appropriate core musculature while practicing the rowing motion on a suspended rowing exercise machine. The apparatus comprises two floor-mounted members secured to each end of a rowing exercise machine that support the rowing exercise machine in a suspended condition. This assembly simulates lateral instability around the metacenter of any of a variety of rowing shells on water by allowing the rowing exercise machine to roll freely around a variety of longitudinal axes. Other embodiments are described and shown.

Abstract: Featured is a controller for a motor that is ultra-compact, with a power density of at least about 20 watts per cubic cm (W/cm3). The controller utilizes a common ground for power circuitry, which energizes the windings of the motor, and the signal circuitry, which controls this energization responsive to signals from one or more sensors. Also, the ground is held at a stable potential without galvanic isolation. The circuits, their components and connectors are sized and located to minimize their inductance and heat is dissipated by conduction to the controller's exterior such as by a thermally conductive and electrically insulating material (e.g., potable epoxy). The controller uses a single current sensor for plural windings and preferably a single heat sensor within the controller. The body of the controller can also function as the sole plug connector.
