Abstract: An improved spinal orthosis for treating scoliosis comprises a semi-rigid brace shell with a split extending from a top end to a bottom end, and a cavity to receive the torso of a wearer. The brace shell defines at least one hole. At least one strap extends inside of a portion of the brace shell, through the at least one hole and around a portion of the outside of the brace shell across the split in the brace shell. The at least one strap is tensioned and the brace shell is closed around the wearer by pulling a first end of the at least one strap and detachably fastening it to the brace shell. The tensioned strap harnesses the elastic potential energy of the closed brace shell to apply dynamic corrective forces to the area of the user's torso most proximate to the apex of the spinal curvature.

Abstract: A device for selectively trimming a tree, the device configured to aerially travel to tree limbs or tree trunks destined for trimming, the device comprising: a transporting assembly configured to aerially transport the device; a tree interface assembly on which is operatively coupled pair(s) of opposing gripping arms disposed to grip the tree therebetween, the tree interface assembly being operatively coupled to the transporting assembly; a transverse rotator comprising a rotational driver configured to rotate the device circumferentially about a tree limb or tree trunk, the transverse rotator being operatively coupled to the tree interface assembly; a cutting assembly comprising at least one cutting mechanism configured to selectively cut a tree limb or tree trunk in multiple planes; wherein the device, once secured to the tree may travel longitudinally along a tree limb or tree trunk to the desired location for trimming.
