New Battery Shuts Down at High Temps, Restarts When Cool

Stanford researchers have developed the first lithium-ion battery that shuts down before overheating, then restarts immediately when the temperature cools. The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from recliners and computers to navigation systems and hoverboards.

Production Code Generator

dSPACE’s (Wixom, MI) latest production code generator, TargetLink 4.1, supports the Functional Mock-up Interface (FMI) 2.0 and the latest version of the AUTOSAR standard, AUTOSAR 4.2. Moreover, MISRA C compliance and code efficiency have been increased further and modular, model-based development is even easier now. Exporting TargetLink models as Functional Mock-up Units (FMUs) allows users to easily exchange and combine models from various modeling environments and Simulink versions, while protecting their intellectual property. Based on the FMI 2.0 standard, users can execute TargetLink-generated code on dSPACE platforms such as VEOS and SCALEXIO, and FMI-compatible environments from third parties.

5mm C-QFN Package

Barry Industries (Attleboro, MA) and Modelithics, Inc. have published a report detailing the broadband performance of Barry's 5mm high temperature co-fired ceramic (HTCC) quad-flat-no-leads (QFN) package to 40GHz. The report presents the accurate modeling of each of the 5mm QFNs 32 pins to 40GHz using a combination of Ansys HFSS 3D simulation and precision Modelithics measurement data. The model features 64 ports for the inner and outer connections of each pin and two model package options depending on the design configuration. The Modelithics model is validated with a comparison to actual measured data, including an example fixture with a transmission line mounted and connected with wire bonds in the Barry package.

Brightness Enhancement Film

American Polarizers Inc. (API) (Reading, PA) has expanded its product offering with 3M Vikuiti™ Brightness Enhancement Films (3M BEF). A single 3M BEF sheet increases the brightness of backlit LCD displays by up to 60%. Placing two sheets at right angles to one another results in up to a 120% brightness increase. Additionally, 3M BEF films promote power savings and thermal management. 3M BEF films contain prismatic structures which refract the light output from the backlight. The prisms send the light back into the LCD. The recycled light then passes out again through the display toward the viewer thereby compressing the light output to achieve the brightness gain. 3M BEF films are available in a variety of standard sheet sizes including, but not limited to, 11” x 11”, 17” x 17” and 24.25” x 24.25” as well as custom sizes.

Development of a Multi-User Modem for Space Telecommunications

This technology has applications in the cellphone industry.

NASA’s Jet Propulsion Laboratory, Pasadena, California

Efficient support of planetary surface missions typically requires an orbiting asset that acts as a relay point to/from Earth. Orbital relay passes are normally 5 to 15 minutes in duration over any specific landed site. When multiple landed assets are co-located or near-located in the same coverage circle of a single relay orbiter, their telecom relay support opportunities will overlap. This will be the case with cooperative lander missions, a lander-rover operations pair, distributed intelligent lander missions, and future deployment of multiple equipment components for support of complex sample return or manned operations. In these situations, the capability of simultaneous support to multiple landers is very valuable for mission performance and operations flexibility. This technology work enables simultaneous telecom support to multiple landers (Mars, Titan, Europa), and provides single-radio, multi-mode support to Entry, Descent & Landing (EDL) and emergency operations (e.g., demodulation + Open Loop Recording).

Wire Bonding to Pads in Tilted Planes

This technique can be used in industries where devices need to be made smaller and lighter, such as medical, aerospace, automotive, and military.

Scientific imaging arrays need to have their individual imaging elements arranged in a close-spaced mosaic. The typical single imaging element is a silicon chip mounted on a larger support frame. This excess area of the support frame takes away valuable imaging space from the mosaic. This appears as a grid of black (no data) in the overall mosaic image. Making the support frame smaller makes the amount of lost data smaller, and the imaging elements can be spaced more closely together. Eliminating the support frame altogether brings the imaging elements even closer. This is referred to as four-side buttable.

cFE/CFS Evolution for Multicore Platforms

Goddard Space Flight Center, Greenbelt, Maryland

This effort ports the Core Flight Executive (cFE)/Core Flight System (CFS) flight software architecture to multicore processor platforms, and provides mission developers with a common, flightready, flexible software environment that supports single, multi-processor, and multicore systems. Currently the cFE/CFS only supports single-core processors.

Hermetic Feedthroughs for Mission-Critical Electronics

Sealed cavities are important in applications such as power electronics for missiles aboard ships or on high-altitude flights; automotive charging stations; and high-voltage power generation.

Douglas Electrical Components, Randolph, New Jersey

One of the most common causes of electronics failure is moisture. Because water and electronics do not mix well, several strategies exist to protect mission-critical components from moisture and condensation. One of the most successful methods involves hermetically sealed electronics cavities enabled by moisture-blocking component assemblies such as hermetic feedthrough technology.
