A method for debt protection or cancellation may include providing an addendum for a debt protection or cancellation product for inclusion in a debt instrument. The method utilizes simulations of an integrated circuit to determine a first amount of time required for a data signal to be transmitted from a first external node to a predetermined node in the register of a static flip-flop, and a second amount of time required for a clock signal to be transmitted from a second external node to the predetermined node. The flaw can be placed at a location selected such that breakage at the cleavage plane will produce long rods and thereby improve the yield of the rod growing process. The pump also has a cover connectable to the housing. The condition data and condition analysis may be entered into and stored in a data store. The primary merit of the present invention is, first of all, free of wiring job, no need of city power, good conformity with environment protective conditions.
