Abstract: Apparatuses and method for determining if an endoscope is contaminated may include a sheath device to cover both the inside and outside of the endoscope. The sheath device may include a flexible tubular external sheath that extends over the endoscope to form an external protective barrier, a tubular internal sheath that extends within a lumen of the endoscope that forms an internal protective barrier, and a cap sealed to both the external sheath and the internal sheath, and a proximal sealing collar that is configured to allow the space between the endoscope and the external and/or inner sheaths to be pressurized to detect leaks indicating contamination.

Abstract: The invention turns a hurricane/tropical cyclone into a tropical rainstorm by spraying a super coolant such as liquid oxygen, or liquid hydrogen, or liquid nitrogen, or other super cold liquid gas around the top of the eye wall and additionally if needed, into the front of the eye wall, or forming eye wall using aircraft with pre-measured amounts of super coolant. Based on actual results, a real time computer system will be developed to enable communications between aircraft and control the amount of super coolant dispersed. The result of the invention will reduce/eliminate the damage to life and property due to high winds and storm surge as well as the staggering costs for rebuilding.
