Software to Control and Monitor Gas Streams
This software package interfaces with various gas stream
devices such as pressure transducers, flow meters, flow controllers,
valves, and analyzers such as a mass spectrometer. The
software provides excellent user interfacing with various windows
that provide time-domain graphs, valve state buttons, priority-colored messages, and warning
icons. The user can configure ...

Histogrammatic Method for Determining Relative Abundance of Input Gas Pulse
To satisfy the Major Constituents
Analysis (MCA) requirements for the
Vehicle Cabin Atmosphere Monitor
(VCAM), this software analyzes the relative
abundance ratios for N2, O2, Ar, and
CO2 as a function of time and constructs
their best-estimate mean. A histogram is
first built of ...

Predictive Sea State Estimation for Automated Ride Control and Handling — PSSEARCH
PSSEARCH provides predictive sea
state estimation, coupled with closedloop
feedback control for automated
ride control. It enables a manned or
unmanned watercraft to determine the
3D map and sea state conditions in its
vicinity in real time. Adaptive path-planning/
replanning software and a control
surface management system will then
use ...

LEGION: Lightweight Expandable Group of Independently Operating Nodes
LEGION is a lightweight C-language software library that enables distributed
asynchronous data processing
with a loosely coupled set of compute
nodes. Loosely coupled means that a
node can offer itself in service to a larger
task at any time and can withdraw
itself from service at any time, provided
it ...

Real-Time Projection to Verify Plan Success During Execution
The Mission Data System provides a
framework for modeling complex systems
in terms of system behaviors and
goals that express intent. Complex activity
plans can be represented as goal networks
that express the coordination of
goals on different state variables of the
system. Real-time projection extends the
ability of this ...

Automated Performance Characterization of DSN System Frequency Stability Using Spacecraft Tracking Data
This software provides an automated
capability to measure and qualify the frequency
stability performance of the Deep
Space Network (DSN) ground system,
using daily spacecraft tracking data. The
results help to verify if the DSN performance
is meeting its specification, therefore
ensuring commitments to flight missions;
in particular, the radio ...

Web-Based Customizable Viewer for Mars Network Overflight Opportunities
This software displays a full summary
of information regarding the overflight
opportunities between any set of lander
and orbiter pairs that the user has access
to view. The information display can be
customized, allowing the user to choose
which fields to view/hide and filter.
