Abstract: A rail-less roof mounting system for installing photovoltaic (PV) modules on a roof structure comprises a base mount assembly that engages with a clamp assembly and attaches to the roof structure. The base mount assembly comprises a base member having a waterproof means, a block slider, a top slider and a covering means. An elevated seal portion of a block slider includes a borehole to receive the waterproof means. A vertical engaging portion of the block slider is attached with a sliding seal member of the top slider. The clamp assembly includes a clamp member and a plate member and the clamp member is attached with a track of the top slider. The clamp member interlocks the PV modules to provide a corner-to-corner coupling arrangement, which enables the connection of PV module corners to adjacent PV module corners by sandwiching above and beneath frame members of the PV modules.

Abstract: A limb support device that includes a vertical support, a base connected to a lower end of the vertical support and a head portion connected to an upper end of the vertical support. The base includes a set of foldable legs that can be positioned upward, where each leg is substantially parallel to the vertical support, or downward, where each leg is substantially perpendicular to the vertical support so that the vertical support is held upright. The head portion has a generally concave saddle that can hold a limb above the vertical support. The saddle can be pivoted so that it can be positioned at a variable angle with respect to the vertical support. The vertical support itself is adjustable in length.

Abstract: A suture anchor made of a single length of resilient wire bent to form a suture retaining loop disposed proximally between two diverging legs with pointed ends sharing an independent plane. The anchor is to be inserted suture retaining loop first into a bone tunnel having a diameter equal to the diameter of the suture retaining loop but smaller than the transverse spacing of the distal points of the static uncompressed legs. The two diverging coplanar legs extend radially till the distal points are set wider than the diameter of the bone tunnel so that when the anchor is inserted into the bone tunnel the static uncompressed legs compress together to penetrate into the bone tunnel. Once the anchor is set deep enough into the hole so that the distal points of each leg are below the surface of the bone cortex the sharp distal points of each leg expand out under pressure and penetrate the tunnel wall prohibiting removal of the anchor and penetrate the tunnel wall in response to applied withdrawal forces.
