A system to monitor the concentrations of trace chemicals in cabin atmosphere is one of the most critical components in long-duration human flight missions. The vehicle cabin atmosphere monitor (VCAM) is a miniature gas chromatograph mass spectrometer system to be used to detect and quantify trace chemicals in the International space station. We developed an autonomous computational process to quantify...
The stand-alone vehicle cabin atmospheric monitor (VCAM) instrument was designed to provide an automated method of monitoring air quality within the International Space Station (ISS) via a miniaturized mass spectrometer and gas chromatograph system. The output of the device, a series of mass spectra as a function of time, is then processed via our implementation of the automated mass spectral deconvolution...
The vehicle cabin atmosphere monitor (VCAM) instrument is designed to autonomously detect and identify trace organic species in the international space station (ISS) cabin air and monitor changes in species concentrations over time after chemical events. The physical instrument is comprised of two subsystems. The first subsystem is a preconcentrator gas chromatograph (PCGC) which separates chemical...
The onboard autonomous science investigation system (OASIS) evaluates geologic data gathered by a planetary rover. This analysis is used to prioritize the data for transmission, so that the data with the highest science value is transmitted to Earth. In addition, the onboard analysis results are used to identify science opportunities. A planning and scheduling component of the system enables the rover...
Mobile devices are rapidly gaining popularity due to their small size and their wide range of functionality. With the constant improvement in wireless network access, they are an attractive option not only for day to day use. but also for in-field analytics by first responders in widespread areas. However, their limited processing, display, graphics and power resources pose a major challenge in developing...
