Abstract: Provided herein is an electric powered digging apparatus comprising: a powerhead, the power head comprises a motor and a gearbox; a handle frame, the powerhead is mounted onto the handle frame; and a drill bit, the drill bit is driven by the motor to rotate around a longitudinal axis, the electric power digging apparatus further comprises: a first safety mechanism, wherein the first safety mechanism reduces torque output to the drill bit when the powerhead spins around the longitudinal axis for an angle larger than a first threshold, and a second safety mechanism, wherein the second safety mechanism reduces torque output to the drill bit when the powerhead spins around the longitudinal drive axis at an angular speed larger than a second threshold FIG.

Abstract: An improved joint support for limiting the range of motion of an anatomical joint comprises intermeshing gears for allowing adjustment of the range of motion of the joint, and comprises plural mechanisms for securing the gears in engagement with one another, whereby adjustment can be made without tools and without disassembly of any components.

Abstract: An orthosis is fitted to a body joint, in a preferred embodiment the equine fetlock, by locating the center of rotation (COR) of the joint; measuring the bones comprising the joint at points located with respect to the COR; selecting the appropriate orthosis from a selection of models thereof; and custom-fitting the orthosis to the individual by heating it to soften a layer of thermoformable foam on the interior of the orthosis, and clamping the orthosis in place over the body joint. A kit of tools for performing the measurements is disclosed, as are a method for location of the COR of the body joint by palpation and a preferred heater.

Abstract: A joint-supporting device comprises tensile members extending from a proximal cuff secured to the limb above the joint to a distal cuff secured to the limb below the joint, supplementing the tensile characteristics of the joint's tendons, ligaments, and other structure. The device may also comprise structure for limiting the range of motion and angular velocity of the joint.

Abstract: An ice skate blade edge measurement device includes a measurement device frame and a measurement indicator. The measurement device frame defines at least one storage location for the measurement indicator such that, when not being used to measure an alignment of a pair of sharpened skate blade edges, the measurement indicator can be stored. One storage location can be on a front side of the measurement device frame away from a measurement location and another storage location can be on a back side of the measurement device frame.
