Moon Tours Android

NASA’s Jet Propulsion Laboratory, Pasadena, California

This Android app provides a native interface to the Lunar Mapping and Modeling Portal’s (LMMP) lunar data archive and analysis tools. It complements the iOS app previously released, incorporating a very similar feature set. Both apps contain a subset of the functionality available in the desktop/Web version. Compared to the iOS version of the LMMP, the Android version provides the additional tools necessary to perform elevation analysis and perimeter/area measurements.

Full-Wave Matching Circuit Optimization Shortens Design Iterations

Full-wave matching circuit optimization (FW-MCO) is a new technology introduced by Remcom, which combines full wave 3D EM simulation and circuit optimization to solve an age-old RF problem:

determining which component values provide the desired match for a given matching network layout.

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).
