Abstract: An invention is presented that will usher in a new and markedly improved era of open, large scale fire fighting. ‘The Invention’ places a CAFS (compressed air foam system) into the fuselage of a helicopter or fixed-wing plane. The CAFS then generates high volumes of effective fire-extinguishing and preventive micellar-foam solution at the attack point of the fire itself rather than refilling at a remote base. It accesses ater contained in a helicopter's Bambi Bucket and refills from a fixed wing plane or other water containing reservoir. The foam solution is then packaged into balloons, made of fire retardant and bio-friendly material, that are accurately and rapidly dropped upon the target fire. ‘The Invention” therefore utilizes and adapts currently available equipment, personnel, and fire-fighting technology to allow a simple, rapid, effective and drastically cost-saving means of extinguishing open fires.

In the event of a fire, additional inert gas is introduced based upon the extent of the fire in the protective room to further decrease from the base inertization level to a first lowered level. The oxygen concentration is maintained at the first lowered level for a first preset time interval, and further decreased from the first lowered level to a full inertization level, if the fire has not yet been extinguished once the first preset time interval has elapsed.

Abstract: A mechanism for reducing the vertical cross-talk interference experienced in signal lines due to the inductive affects from signal lines in other signal planes of a multi-layer ceramic package is provided. With the apparatus and method, one or more vias in the multi-layer ceramic package may be removed from the structure to provide area through which an offset of the signal lines may pass. Because these offsets of the signal lines exist in parallel planes above or below each other, with no ground lines existing directly between these signal line offsets, a capacitive cross-talk is introduced into the signal lines. This capacitive cross-talk is opposite in polarity to the inductive cross-talk already experienced by the signal lines. As a result, the capacitive cross-talk tends to negate or reduce the inductive cross-talk thereby reducing the far end noise in the signal line.
