Health Interrogation for Space Structures (HISS)

Invocon's Health Interrogation for Space Structures (HISS) system provides a significant improvement over current alternatives for monitoring pressurized space structures for leaks and impacts. HISS will quickly detect and locate leaks based on their acoustic emissions or other signature. It will provide prompt warnings to flight and ground personnel in order to help save the vehicle (and mission). It will also complement the present Environmental Control and Life Support System (ECLSS) capabilities by providing leak location as well as warning of the leak up to several minutes before the ECLSS. The primary transducers with which HISS interfaces are acoustic emissions. However, Invocon plans to design HISS so that it will interface with other types of sensors in order to maximize its usefulness. This will allow HISS to be used for many other flight and ground monitoring applications.
