OSI Laser Diode, Inc. (LDI) (Edison, NJ) has introduced a 1550 nm pulsed laser diode with an integrated micro lens that delivers a far‑field beam pattern. The beam pattern's divergence is equivalent in both the Fast (perpendicular) and the Slow (parallel) axes of emission. The CVLL 350‑CL90 pulsed laser diode beam divergence (FWHM) is 8 x 8 degrees. The adjusted Far Field pattern offers high coupling efficiency when used with standard spherical lens systems. LDI's new device is RoHS compliant and operates in wavelengths ranging from 1530 nm to 1580 nm, with 1550 nm typical. The operating temperature is 25 degrees C, the pulse width is typically 150 nanoseconds, frequency is 5kHz, the drive current is at 75 W, and peak power is at 22 W.

Excelitas Technologies Corp. (Waltham, MA) recently announced the X-Cite® 110LED, a new compact white light LED source for fluorescence imaging applications.

A cable installation simulator from W. L. Gore & Associates aids in evaluating the stress of installation on microwave airframe assemblies, thereby minimizing the risk of cable assembly damage or failure during installation. By comparing signal integrity before and after installation, Gore can engineer assemblies that withstand airframe installation as well as the demands of the aircraft’s flight envelope. Use of the installation simulator gives aircraft manufacturers and installers evidence that their assemblies will provide the same level of electrical performance after installation as when they are new.

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.

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.

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.

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.

It is fairly well known within the aerospace community that telemetry is moving from the traditional L-band and S-band frequency ranges up to C-band. It is widely understood that the reason for this push to C-band is two-fold. First, traditional L and S frequency bands have been greatly reduced through reallocation for a variety of reasons by different markets, and second, the bandwidth required for most applications has seen exponential growth. This has not only been seen in military applications, but in civilian aerospace platforms as well.

As wireless standards become more complex, the number of operational modes for these devices increases exponentially. As progression continues to the latest WiFi standard, new modulation schemes, more channels, more bandwidth settings, and additional spatial streams are added. Additionally, characterizing WLAN transceivers is especially challenging when faced with thousands of independent operational gain settings.
