Big Data, Aircraft, and a Better Future

The hype phrase today is “Big Data.” It is a phrase Mark Bünger, Research Director for Lux Research, believes can have a number of definitions depending on who is doing the defining. Bünger was the lead analyst on a report that Lux published in April 2015 that surveyed both the technology as it is today and how various industries are adapting to the opportunities—and perils—in trying to exploit it.

30 GHz and 35 GHz Microstrip Isolators

TRAK Microwave (Tampa, FL) has announced two new Microstrip Isolators covering popular mm-wave frequency bands. Models T001110 (29.6-30.6 GHz) and T001111 (34.5-35.5GHz) integrate ferrite circulator/ isolator substrates on to printed circuit board (PCB) material providing for a high performance, yet economical, solution. Typical insertion loss is 0.8dB, return loss 20dB, and isolation of 20dB. These devices handle RF power levels consistent with T/R Module applications in phased array radar or SatCom tracking antenna systems.

Avionics Interface Computer

Data Device Corporation (Bohemia, NY) has introduced the Avionics Interface Computer (AIC), providing a scalable, programmable, and portable platform to develop and test MIL-STD-1553 and ARINC 429 system applications via an Ethernet network. The AIC features 2 PMC and 2 Mini- PCIe expansion sites, allowing users to select interface boards optimized for their specific application and connectivity needs. An onboard Intel® Atom™ E3845 Quad Core 1.91GHz processor provides programming flexibility and simplifies connectivity by automatically bridging messages in real-time between Ethernet, ARINC 429, and MIL-STD-1553. The BU-67121W AIC also lowers the complexity and cost of many long discrete cables by locating the 1553/429 interfaces close to onboard electronics, and using the Ethernet interface to provide network access and control from the test lab.

Adaptive IF Relay XMC

Pentek, Inc., (Upper Saddle River, NJ) has introduced the newest member of its Cobalt® line of XMCs (Switched Mezzanine Cards). The Model 71624 dual channel, 34 signal, adaptive IF (Intermediate Frequency) relay XMC with a Virtex- 6 FPGA accepts two IF analog input channels, modifies up to 34 signals, and then delivers them to two analog IF outputs. Any signal within each IF band can be independently enabled or disabled, and changed in both frequency and amplitude as it passes through the module. The Model 71624 features 34 digital down converters (DDCs), each independently tunable across a 100 MHz input IF range, handling signal bandwidths from 20 kHz up to 312 kHz. The DDCs deliver 34 baseband signals to the host computer, which determines how each signal is dropped, replaced, or changed in amplitude and frequency. The modified signals are then combined and delivered as an analog IF output.

Brushless DC Motors

BEI Kimco Magnetics (Vista, CA) has developed new frameless brushless DC motors in multiple designs for a variety of applications including robots and remotely piloted military vehicles. These new motors provide operational efficiencies in excess of 90% by utilizing proprietary low magnetic circuit design techniques to extend battery life. Other important features include a frameless motor design composed of two pieces a rotor and stator. This design makes it easy to integrate into a customer’s existing assembly, minimizing the need for extra components and reducing overall weight. Motors range up to 20" in O.D. with torques in excess of 50Nm and operational speeds beyond 70K rpm.

Fabricating Transparent and Stretchable Supercapacitors Based on Wrinkled Graphene Electrodes

Stretchable electronic devices, including solar cells, light-emitting diodes, batteries, and textile supercapacitors, have been developed to retain their functions even when under large strains (up to 40%). Some transparent solar cells, batteries, and supercapacitors have also been developed. However, most of the currently developed electrodes and the associated supercapacitor cells cannot be both transparent and stretchable.

Modular Exhaust Design and Manufacturing Techniques for Build-to-Order Muffler Systems

Managing the acoustic signature of military vehicles can play a critical role in the safety of soldiers. Low-frequency sounds propagate through the atmosphere, resulting in unacceptable acoustic vehicle detection ranges, requiring relatively large silencer structures to mitigate. Currently, these requirements are met by using a custom muffler that is hand-assembled using low-volume prototyping manufacturing techniques. This method results in significant engineering and manufacturing time.

Silicon Microsphere Fabrication

The efficiency and methodology of coupling light into microcavities has improved exponentially in the last decade. One such advancement is coupling light onto silicon microspheres. The material, size, and shape of a silicon microsphere are ideal for optical devices. Silicon microspheres are not the primary material used to fabricate microspheres for optical coupling because current methods used for microsphere fabrication cannot produce single-crystal silicon in the 16-μm scale, which is best for current optical technology.
