A trampoline system has a rebounding bed and a resilient member located below the bed at such a position that the bed depresses the resilient member when the bed is sufficiently depressed by a person jumping on the bed. The presence of the resilient member makes it easy tune the system to adjust the performance of the trampoline and to minimize impacts on a jumper and thereby reduce the likelihood of bed-impact injuries.

A suspension having a magnetic head assembly 1 mounted thereon is provided, wherein the magnetic head assembly comprises: a write head 1-2; a read head 1-1; and a resistive heating element 1-3 for controlling the flying heights of the magnetic heads, wherein the wires HTx and GTx for the resistive heating element is disposed such that they sandwich the wires RxX and RxY for the read head. The wires for the resistive heating element may be disposed between the wires for the write head and the wir...

A tool for treatment of an ingrown toenail includes a tubular member having a length of about 1 2 cm and being tapered such that a diameter at a root is about 2 mm and a diameter at a tip is about 2 mm. Holes are distributed over the tubular member. The tubular member has a slit with saw-tooth edges and has a C-shaped cross section. A side edge of a nail plate is inserted into the slit and the saw-tooth edges secure the tubular member to the nail plate. A super elastic wire is inserted into one ...

A spring arrangement for a trampoline includes a rebounding surface, a frame structure having a top portion and a bottom portion, and a plurality of spring members that are mechanically coupled between the rebounding surface and the frame structure. A first group of spring members are mechanically coupled to the top portion of the frame structure and a second group of spring members are mechanically coupled to the bottom portion of the frame structure. In one exemplary embodiment, the spring mem...

A protective cover for a trampoline assembly that includes an attached safety enclosure has a plurality of edge cuts out coinciding with the connections of the bottom of the safety enclosure netting to the portions of the trampoline disposed with the diameter of the supporting frame. Elastic connecting members are provided at the intersection of each cutout with the periphery of the circular cover so that it is fastened to protect the trampoline frame and rebounding mat. The protective cover can...

A fence surrounds a trampoline and extends above the rebounding surface, reducing the risk of injury. Shock absorption is aided by a support system of independent poles. Variable placement net fasteners also are detailed.

A trampoline provides higher performance and greater shock absorption capability by utilizing pairs of springs to connect the rebounding mat to the supporting frame. The springs in each pair are coupled to a common junction on the periphery of the rebounding mat, being disposed vertically with respect to each other. The upper spring in each pair is directly connected to the rebounding mat and the trampoline frame to initially to tension the mat in the equilibrium position. The lower spring in ea...

An implantable device that can automatically monitor and record patient activity as sensed by an activity monitor. In certain variations, the activity monitor can include an accelerometer providing three-axis acceleration signals and in other variations the activity sensor can include a position sensor, such as a GPS receiver. The implantable device automatically determines if patient activity exceeds a determined threshold and monitors and records a total equivalent distance traveled for a dete...
