A fishing lure consists of a hook and at least one bladed member having an aperture for slidably mounting the bladed member along the shank of the hook. A plurality of through channels 7 are formed in the honeycomb segment 2, and the cells are constituted as inlets andor outlets of the through channels 7 and contain a plurality of honeycomb segments 2 bonded to one another. The echo canceller may also include a near-end talker signal detector which may be used to prevent the adaptive filter from adapting when a near-end talker signal is present. The controller then undistorts the images of these areal portions and projects them back onto the display so that an operator can position undistorted digital representations of pattern pieces onto the undistorted images of the work material.
