Abstract: An apparatus and method for characterizing a region of interest (ROI) including measuring position and orientation data within the ROI; and generating a geometric data set to include one or more of: length, bifurcation location, angle and curvature characteristics of the ROI. Also, sequentially taking an image of a tool within the ROI; comparing tool dimensions with ROI dimensions; and estimating diameter, length, take-off angle, and/or tortuosity characteristics based on the comparisons.

Abstract: A fastener for anchoring fencing to a post. The fastener includes first and second separable and complementary sections, each section have an inner and outer surface, a middle web portion, opposed first and second sides extend from opposite edges of the middle web portion in a direction outwardly from the middle web portion, and opposed first and second ends. Male coupling members extend in a direction outward from one of the sides of the first section and the second section has female receiving spaces on one of the sided. Wherein the male coupling members being biasable for engagement with the spaces to detachably secure the sections together with the inner surfaces facing one another such that the inner surfaces define an axial passage that extends from the first to the second ends of the sections, whereby the passage permits the fencing and post to be clamped together between the sections.
