Tablet Cameras

Motic (Richmond, British Columbia) has figured out a way to turn tablet computers into dynamic imaging stations that will preview, acquire, store, measure, and communicate microscope images. Built on Android technology, Motic’s new line includes two tablet cameras, the 7” Moticam S2 and the 10” Moticam T2. Both Tablet Moticams are managed by Android’s powerful 1.6GHz quad core processors using 1GB of DRAM, and both sport brilliant 1280x800 displays. The S2 provides 8GB internal memory while its bigger cousin boasts 32GB. Because images devour storage, both systems are equipped with Micro SD cards (up to 32GB). They also “play well with others”, readily sharing images and movies via Bluetooth, WiFi, and HDMI connections.

Spectrometer Platform

Ibsen Photonics (Farum, Denmark) recently announced the new FREEDOM HR spectrometer platform for integrators of compact analytical and process control instruments. The new HR platform consists of FREEDOM HR-UV, HR-VIS, and HR-VIS-NIR for high resolution down to 0.2 nm in the UV, 0.4 nm in the VIS and 0.6 nm in the VIS-NIR. The size of the spectrometer is only 61 x 64 x 19 mm. All FREEDOM spectrometers can be configured with a range of CCD, CMOS, and NMOS detectors as well as an optional USB controller and accompanying software. The spectrometers are robust and almost athermal and can operate under demanding environmental conditions.

Laser Interferometer

4D Technology Corporation (Tucson, AZ) has introduced its newly improved AccuFiz compact laser interferometer for accurate, repeatable measurement of surface shape and transmitted wavefront quality. New features include long- range wireless remote control, motorized tip-tilt and a variable sensitivity alignment system. The wireless remote provides control over instrument set- up, data acquisition and the motorized tip-tilt, for precise system adjustment without disturbing the cavity. The improved alignment system makes it easy to align weakly reflecting samples and high-loss cavities, even in high ambient lighting conditions. The new Surface Isolation Source option adds a second, external laser source to measure plane parallel optical surfaces, without the need for messy coatings or back-surface treatments to eliminate unwanted reflections.

Electronic Warfare Technology

Military electronic warfare (EW) systems including navigation, radar guidance, terrain mapping and others, require lightweight compact components, with radio frequency (RF) output power levels to several kilowatts typically needed to meet system requirements. As GaN transistor technology advances in frequency and power output, solid state power amplifiers (SSPAs) have begun replacing traveling wave tubes (TWTs) at frequencies up to 6 GHz. The utilization of this technology results in a lower cost and greater efficiency over the life of a product.

Cloud Security & Compliance

Not too many years ago, network security was a relatively low level priority in most organizations. That has changed today due to such high level failures as the recent breaches at Sony and Target. Closer to home, the University of Maryland is now incurring large expenses for all students due to the recent leak of personally identifiable student information.

MicroTCA Computing for Mil/Aero Applications

Small Form Factor (SFF) embedded systems have been gaining popularity due to their small size, weight, and power (SWaP) advantages. The SFF architectures are typically purpose-built, providing just a few specific functions. But, the performance level is often limited and the versatility and re-usability across multiple applications is typically very low. Is a balance available where there is high performance and versatility in an open standard architecture, but a compact size that is optimized for SWaP-C (C stands for cost)?

Fanjet Evolution — the Next Steps

The global aerospace sector has always represented the cutting edge of practical technology advancement. When the first military jet engines emerged in the post-war 1940s it was clear that commercial applications would soon follow. The leap in performance, payload capability, maintainability, and speed compared to the best that turbo-supercharged piston-engines could offer was truly revolutionary.

Electronic Warfare Development Targets Fully Adaptive Threat Response Technology

When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals — a technique known as electronic attack (EA) or jamming. Conversely, electronic protection (EP) technology prevents hostile forces from using EA methods to disable U.S. radar equipment assets.
