Advanced Magnetostrictive Regulator, Valve, and Force-to-Angle Sensor

The components are lightweight, compact, highly precise, and can operate over a wide range of temperatures and pressures. Marshall Space Flight Center, Alabama Typical aerospace rocket engines use valves to control the flow and pressures of propellant and pressurants. These typical valves are designed to operate with a mechanical, electromechanical, or pneumatic operator. They all have at least one, and often multiple, penetrations from the fluid to the operator’s prime mover. The penetrations are sources for leaks, failures, and are often considered to be unreliable for use in single string systems. Therefore, the fluid system designer frequently will utilize several parallel path valves, effectively doubling the resources needed to accomplish the task. These redundant valves allow for isolation of the potentially leaking fluid penetrations. If the systems cannot afford the multiple path approach, then the valves are subjected to high levels of testing and quality control, or utilize bellows or other expensive and difficult to handle/design and costly features.

Simple Impedance Matched Planar Microwave Blocking Filter

Goddard Space Flight Center, Greenbelt, Maryland Thermal blocking filters find wide use in cryogenic applications ranging from quantum computing to ultra-low-noise detectors. They can be used to provide the environmental isolation between cooled devices and the warmer temperature supporting bias and readout circuitry. In particular, they are effective in rejecting thermal radiation, limiting radio frequency interference, and providing a convenient means of heat sinking or realizing a vacuum feedthrough for signal lines.

High-Data-Rate Platform to Capture and Analyze Raw Baseband Clock/Data

NASA’s Jet Propulsion Laboratory, Pasadena, California The Space Communications and Navigation (SCaN) Testbed has a need to capture and analyze high-datarate (<2 Mbps required) baseband information sent over RF by the JPL Software-Defined Radio (SDR). An RF4425 front end, coupled with a MicroGate Synclink USB and custom C++ software back end, is being used to answer this need.

Coming Soon - Accelerate Development of Powertrain ECUs with Virtual Hardware

In conjunction with SAE Automotive powertrain ECUs are increasingly reliant on complex MCUs/SoCs with multicore architectures, complex programmable timers, such as Generic Timer Module (GTM) and communication protocols that integrate CAN-FD, FlexRay, and Ethernet. Beyond the hardware components, there is also greater reliance on embedded software to achieve the required fuel efficiency/emission standards and the need to satisfy safety standards, such as ISO 26262.

Coming Soon - Unlocking the Secrets of Amorphous Metals

What do bulk metallic glasses (BMGs), amorphous metals and liquid metals all have in common? Basically they’re all the same thing – non-crystalline metal alloys that are simultaneously glasses, metals, and liquids. Sounds impossible, doesn’t it? But it’s not. And they possess some incredible properties. Think of them as the shape-shifting superheroes of the materials world.

Coming Soon - Advanced Passive Thermal Management Technologies for Power Electronics: Solutions to Reduce Noise, Power Consumption, and Operating Costs

Components housed within power electronic devices continue to shrink in size and increase in power. This trend results in high heat flux components integrated into small packages; driving the need for enhanced thermal management to ensure high performance and long life for the devices. Properly managing the thermal loads within these systems can be challenging; and traditional solutions of larger pumps and fans result in more noise and higher power consumption.
