Hello, I work for the NASA Technology Transfer Center. We take the latest NASA developed technologies and try to find commercial applications for them. If you are interested in seeing one of NASA's latest ice detection technologies, you can view information by going to the address below: http://monica.usc.edu/CommQuest/deice/ We would like to get your opinion on potential commercial uses for the Ice Detector and Deicing Fluid Effectiveness Monitoring System. You can give us your feedback through the web site or by sending an e-mail to : firstname.lastname@example.org We appreciate your input, Rob Dabney Project Manager NASA Far West RTTC Technology Description: Developed by the NASA Ames Research Center, the ice detector and deicing fluid effectiveness monitoring system measures atmospheric conditions and the thickness of ice to provide information on the effectiveness of deicing fluid being applied. Ice Detector and Deicing Fluid Effectiveness Monitoring Systems can be used to detect the formation of ice and to ensure that the minimum amount of deicing fluid is used to melt ice. The system detects ice at levels you specify and continuously monitors the concentration and amount of deicing fluid needed to deice a surface, thereby minimizing pollution of the environment from excess deicing fluids. The technology saves energy and chemicals by deicing only when needed instead of automatically or periodically. The system is ideal for use in airplanes and helicopters but could also be used in commercial refrigeration applications, road surfaces and a number of other commercial applications. In flight applications, It is crucial for a pilot to know that a deicing process has been completed successfully. The flight crew can detect and monitor the deicing process to make sure all ice has been removed. This ensures that no more deicing fluid is applied than is needed, which will prevent excessive harm to the environment. In commercial refrigeration applications the Ice Detector and Deicing Fluid Effectiveness Monitoring System would deice only when ice is detected. Currently, many commercial refrigeration systems deice on a scheduled or automatic basis. Applying this technology could greatly reduce energy and chemical consumption in refrigeration systems. The invention consists of two components: an ice detector and a deicing fluid effectiveness monitoring system. The ice detection portion is composed of a temperature sensor and a parallel arrangement of electrodes whose coefficient of coupling indicates the formation and the thickness of the ice. The fluid effectiveness-monitoring portion comprises a temperature sensor and an ionic-conduction cell array that measures the conductivity of the deicing fluid, which depends on its concentration and its freezing point.
