  • Patent number: 11055671
    Abstract: In accordance with various embodiments of the disclosed subject matter, a system and method is configured for generating maintenance events in response to threshold levels of accumulated corrosive stresses experienced by assets or components thereof based on environmental and weather data correlated to respective locations visited and a model of corrosive susceptibility of the assets or components thereof.

  • Patent number: 9863725
    Abstract: Ammonium carbamate-based methods and systems for management of thermal loads, particularly low-quality, high-flux thermal loads. The increase in temperature in heat sensitive devices is mitigated by the endothermic decomposition of ammonium carbamate into carbon dioxide and ammonia gases. This process has an energy density an order of magnitude greater than conventional thermal management materials and is particularly useful for temperatures between 20° C. and 100° C. Systems incorporating ammonium carbamate may be controlled by regulating the fluid flow, overhead pressure, temperature, or combinations thereof.
