Tailor-made Computing Solutions Require Diverse I/O Functions

More than ever, users from industry and transportation expect the full system solution, but no longer want to have to worry about the cumbersome configuration and integration of individual hardware components and adapting the software. There is a very simple reason for this: the system supplier of their choice reduces the time to market and is also responsible for the entire system at the same time.

Stackable Form-Factor Peripheral Component Interconnect Device and Assembly

Applications include fault-tolerant computing systems, high-speed data acquisition, embedded servers, and intelligent transportation systems.

The invention is a design for a peripheral component interconnect (PCI) local bus controller and target in a PC/104-Plus form-factor. The design uses a flash-based field programmable gate array (FPGA) to provide immediate functionality from power-on to avoid delay after power is applied. It can be reprogrammed from connectors directly on the board, and is able to both receive and drive the clock for system and local peripherals, allowing it to function as either a PCI bus host controller or PCI target device interface. Fully compliant with the PC/104-Plus specification, the design has associated schematics and Gerber files in a vendor-ready state. The design was developed to support ongoing research in fault-tolerant computing systems.

Self-Healing Wire Insulation

Microcapsules release healant that repairs minor cuts, nicks, and abrasions.

NASA’s Kennedy Space Center is seeking commercial partners for licensing or further development of a novel high-performance, flexible, low-melt polyimide film with self-healing properties. The self-healing properties of the film are provided by embedded microcapsules containing a solvent-soluble polyimide. When cut or otherwise damaged, these capsules release their contents, which dissolve and heal the damaged area.

Vibration Damping Circuit Card Assembly

NASA’s Marshall Space Flight Center has developed a particle impact damper (NASA damper) that can be used in circuit card assemblies to reduce vibrations encountered during space vehicle launch. The damper, filled with high-density metallic beads, is attached to printed circuit boards (PCBs) and printed wiring assemblies (PWAs) to dissipate vibrations and improve component reliability and robustness. Testing has demonstrated an order-of-magnitude reduction in observed peak vibration response, and dramatic improvement in circuit component life span. The NASA technology provides simple and inexpensive vibration reduction for sensitive heritage or commercial off-the-shelf (COTS) electronics in applications where the vibration environment is either severe or exceeding its original design envelope. The technology can benefit heritage hardware in a wide range of applications as a retrofitted upgrade, or can be incorporated into the design of new circuit cards.

Development of a Metallic Bilayer Liftoff Mask

A large variety of cryogenic detectors need to be fabricated on thin dielectric membranes in order to have high signal-to-noise attributes. Unfortunately, many of the etching processes used to define the detectors can roughen or even completely dissolve the membranes. These types of membrane damage degrade the detector performance and limit fabrication yield.

Safety in SoCs

Accelerating the Road to ISO 26262 Certification With Processor IP

Today’s system-on-chip (SoC) designs are becoming more complex, increasing the pressure on verification and design teams to deliver fully functional designs. Recent studies have shown that over 50% of the development time on a complex IC is now being spent on verification, revealing the severity of the problem project teams are facing. As more SoC designs are used in electronic systems deployed in safety-critical applications, adhering to functional safety standards such as ISO 26262 has become an important consideration when defining the verification methodology. This white paper outlines the key requirements for ISO 26262 certification and demonstrates how to accelerate the development of safety-critical IP and SoCs through the use of out-of-the-box safety-ready IP with advanced verification qualification tools and methodologies.

High Field Superconducting Magnets

Applications include MRI machines, mass spectrometers, and particle accelerators.

Goddard Space Flight Center, Greenbelt, Maryland

A modified coil winding machine for small-diameter wire being used to enable higher packing densities for the superconducting magnets.

This superconducting magnet developed at NASA Goddard Space Flight Center comprises a superconducting wire wound in adjacent turns about a mandrel to form the superconducting magnet; a thermally conductive potting material configured to fill interstices between the adjacent turns; and a voltage limiting device disposed across each end of the superconducting wire, and is configured to prevent a voltage excursion across the superconducting wire during quench of the superconducting magnet. The thermally conductive potting material and the superconducting wire provide a path for dissipation of heat.
