Abstract: A bale wrapping control system that enables several custom bale wrapping patterns which more effectively wrap and maintain the integrity of bales formed in a round baler. The bale wrapping control system controls operation of a dispensing arm which dispenses twine or other bale wrapping material. The dispensing arm is moveable between a start position where an end of the dispensing arm is closest to the bale, a left edge position where the end of the dispensing arm is near a left edge of the bale, a right edge position where the end of the dispensing arm is near a right edge of the bale, and a cutoff or home position where the end of the dispensing arm passes a cutting mechanism. The bale wrapping control system includes a baler controller for controlling movement of the dispensing arm and a user interface for receiving operating instructions from an operator of the baler and for controlling certain functions of the baler controller in response to the operating instructions.

Abstract: A method for reactive ion etching of SiO2 and an etch stop barrier for use in such an etching is provided. A silicon nitride (SixNy) barrier having a Six to Ny ratio (x:y) of less than about 0.8 and preferably the stoichiometric amount of 0.75 provides excellent resilience to positive mobile ion contamination, but poor etch selectivity. However, a silicon nitride barrier having a ratio of Six to Nx (x:y) of 1.0 or greater has excellent etch selectivity with respect to SiO2 but a poor barrier to positive mobile ion contamination. A barrier of silicon nitride is formed on a doped silicon substrate which barrier has two sections. One section has a greater etch selectivity with respect to silicon dioxide than the second section and the second section has a greater resistance to transmission of positive mobile ions than the first section. One section adjacent the silicon substrate has a silicon to nitrogen ratio of less than about 0.8.
