Eliminating Wires in Making Electrical Connections to a Stack of Electron and Ion Optical Components

This technology can be used in environmental monitoring applications that require miniature, robust mass spectrometers. NASA’s Jet Propulsion Laboratory, Pasadena, California Making electrical connections inside a vacuum chamber to a stack of electron and ion optical components using the conventional approach of discrete wires is not efficient because: (1) the separate wires must be insulated from each other and the interior structures; (2) the wires must be spot welded or mechanically secured at their end points to the electrical feedthroughs and optical components, both of which are typically bulky and prone to failure in vibration; and (3) the wires are a major source of failure in high-G applications.

Graphene Composite Materials for Supercapacitor Electrodes

Graphene is combined with a metal oxide nanocomposite. Ames Research Center, Moffett Field, California In recent years, electrochemical capacitors, or supercapacitors, have gained the most intense interest as an alternative to traditional energy storage devices such as batteries. The demands of the potential supercapacitor applications range from plug-in hybrid electric vehicles (PHEVs) to backup power sources. While the power density of supercapacitors surpasses that of most batteries, most commercially available batteries have a significantly higher specific energy density than supercapacitors. Electrode composite materials have been developed that combine graphene with a metal oxide nanocomposite of MnO2 and Co3O4.

Integrated, Radiation-Hardened Radio Frequency Digitizer and Signal Processing Electronics

Goddard Space Flight Center, Greenbelt, Maryland Imaging LiDAR systems such as Goddard’s Reconfigurable Solid-state LiDAR (GRSSLi) must collect and process reflected pulses of light in order to correctly assemble a three-dimensional image of the scene. These pulses of light generally range from 2-5 nanoseconds in duration. Consequently, to collect a large number of samples for this short pulse, a high-sample-rate analog to digital converter (ADC) must be used. Other methods such as threshold detection could be used, but generally these detection methods suffer degradation in overall range, measurement accuracy, and precision due to the random nature of return pulse intensity. In addition, scientifically valuable information can be gleaned from the shape of the returned waveform.

Designing Antenna and Electronic Systems for Space and Airborne Applications

Across all industry sectors electronic systems such as antennas and sensors are becoming ubiquitous in support of wireless communication, sensing and power transfer. These are examples of the practical realization of the "Internet of Things". In the aerospace sector, such technologies are playing an increasingly important role in advanced technologies. For example, highly instrumented and connected aircraft are supporting condition based maintenance and health monitoring techniques. Remotely piloted systems are becoming more autonomous and delivering increasing amounts of intelligence, surveillance and reconnaissance data to support the warfighter. At the same time, the industry is expected to deliver these more advanced capabilities at lower cost, in a smaller and lighter footprint and with increased robustness, reliability and resilience.
