DRAM Modules

DRAM modules from Innodisk Corp. (Taipai, Taiwan) feature conformal coatings that protect against moisture, dust, and chemical contaminants. The layer thickness varies from 0.03mm up to 0.13mm, depending on the demands of the application and the materials used. The coating also protects against issues caused by electrical or thermal conduction, static electricity, and heat, and observes MIL-I-46058C.

Enclosure Gaskets

Beryllium-copper fingerstock gaskets from Leader Tech (Tampa, FL) provide electrical contact between parallel seams (mating surfaces) that are created by enclosure access doors and panels. Once installed, the hardened Alloy 25 gaskets effectively shield over a broad frequency range. Leader Tech fingerstock gaskets, available in multiple plating finishes, can be cut to application-specific lengths. In addition, the wiping action of gasket fingers acts as a self-cleaning mechanism during every compression cycle.

All-Diamond Packaging Solution

In collaboration with the University of Warwick, Element Six (Santa Clara, CA) has developed an all-diamond sensor structure for electroanalytical applications. The synthetic electrode is available in a variety of geometries encapsulated in co-planar insulating diamond. Element Six’s Diafilm EA-grade electrode material features 100 percent phase purity, and the electrode presents a typical surface roughness of Ra<0.02 μm. Precisely controlled boron concentrations provide metal-like ohmic conductivity while achieving low capacitance.

L- and S-Band High Gain Amplifiers

Pasternack Enterprises (Irvine, CA) has announced a new portfolio of Land S-band high gain amplifiers. The modules, packaged in hermetically-sealed metal enclosures, are optimized for 1.2 – 1.4 GHz and 3.1 – 3.5 GHz radar applications. The RF amplifiers utilize a hybrid microwave integrated circuit design and GaAs pHEMT technology. The devices also feature built-in voltage regulation, bias sequencing, and reverse bias protection.

Reaching the Benchmark in Secure Unmanned Vehicle Software

Security concerns currently dominate software thinking wherever sensitive or safety-critical information is potentially accessible. Embedded software is no exception. Security researcher Barnaby Jack demonstrated this in 2011 when he used a modified antenna and software to wirelessly attack and take control of Medtronic’s implantable insulin pumps. He demonstrated how such a pump could be commanded to release a fatal dose of insulin. Obviously, that vulnerability puts dependent diabetics at risk.

Submersion and Directed Flow Cooling Technology for Military Applications

As the US military shifts from boots on the ground to drones in the sky, there will be an increasing need for computing power on foreign soil, under the sea and in the air. Design objectives will be difficult to achieve with legacy technology. Electronic gear must be deployed by transport plane and require rapid setup once the destination is reached. Systems will need to be hardened to survive extreme temperatures, desert sand, salt air and pollution. Fuel logistics to serve remote locations can be difficult and expensive. Every kilowatt-hour of electricity converted to heat must be dissipated and, ideally, the waste energy should be recycled. For ground installations, it will be useful to consider distributing computing resources around rather than concentrating them at a single location that may be vulnerable to attack. Silent operation also is desirable.

Flying on Vegetation

Fuel is expensive for airlines. According to sources interviewed for this article, fuel accounts for 30 to 50% of operating costs, depending on the size of the aircraft. And fuel prices remain volatile.

Avionics Heat Up, in a Good Way

The common feature shared by recent aviation platforms is the high level of systems integration, and the way in which information is displayed or made accessible, allowing previously unimaginable levels of situational awareness to be available to pilots and ground controllers. This has greatly eased the pilot workload and enhanced flight safety, especially when flying in poor weather or operating in unfamiliar or hazardous terrain.
