A method of updating reflection coefficients of a lattice filter is provided, which method includes the step of updating backward reflection coefficients by employing forward reflection coefficients which are updated so that a forward prediction error of a last stage of the lattice filter is minimized. Methods are provided in which a set of aging preferences are obtained. Respective antennas may successively be activated to transmit interrogation signals. The method and apparatus for data re-arrangement further includes retrieving an input pixel based on the initial input pixel coordinates and the offset value. The cam portion moves the engagingly-locking protrusion beyond the engaging-lock receiving protruding portion from behind it to the engaging-lock receiving portion, or guides the engagingly-locking protrusion from the engaging-lock receiving portion to behind the engaging-lock receiving protruding portion so as to pass by one lateral side of the engaging-lock receiving protruding portion.
