Rocket Science May Improve Kidney Dialysis

Researchers in the United Kingdom have found a way to redesign an artificial connection between an artery and vein, known as an Arterio-Venous Fistulae (AVF), that surgeons form in the arms of people with end-stage renal disease so the patients can receive routine dialysis. The new design may decrease the likelihood of blockages in AVF, which is a major complication of dialysis.

Are Airships the Future of Aviation?

Researchers from the University of Lincoln, UK, have completed a three-year study of stratospheric passenger airships designed to provide a future sustainable air transport network. The Multibody Advanced Airship for Transport (MAAT) project aims to position airships as the solution for future air transportation that is safe, efficient, cheap, and environmentally friendly.

Unmanned Aircraft Inspect Energy Pipeline

A fixed-wing unmanned aircraft was used to inspect an energy pipeline route with a piloted chase plane following behind to ensure safety beyond the ground observers' sight line. The flight was a step toward making aerial inspections of energy pipelines safer and more economical. The test aircraft was equipped with a special sensor package to identify threats to pipeline integrity.

Assisted Steering for Efficient Turning of Electric Vehicles

Scientists are developing a new assisted steering concept for electric vehicles. In conventional vehicles, the internal combustion engine not only accelerates the car, but also supplies onboard assist systems with energy, such as the assisted steering system, which reduces the strain on the driver at the wheel. In electric vehicles, this energy comes from the battery, and also reduces the range as a result. In this case, the steering system is assisted in an energy-efficient manner by intelligent control of the drive torques transmitted to the individual wheels.

New Technology May Double Radio Frequency Data Capacity

A team of Columbia Engineering researchers has invented a new technology called full-duplex radio integrated circuits (ICs) that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible; transmitters and receivers either work at different times or at the same time but at different frequencies. The Columbia team, led by Electrical Engineering Associate Professor Harish Krishnaswamy and funded by the DARPA RF-FPGA program, is the first to demonstrate an IC that can accomplish this.

Innovative Army Tool Enhances Electronic Warfare Capabilities

Beginning with the early stages of Operations Enduring Freedom and Iraqi Freedom, the Army has steadily increased its electronic warfare (EW) capabilities from both a manpower and equipment standpoint. In particular, significant progress has been ongoing since the Army reestablished its EW corps and set up the Project Manager Electronic Warfare office in 2009 to provide materiel solutions that protect soldiers from radio-controlled improvised explosive device (IED) attacks and provides them with an accurate and complete understanding of their environment across the electromagnetic spectrum.

Scientists Unlock Secrets of Super Solar Power Perovskites

The best hope for cheap, super-efficient solar power is a remarkable family of crystalline materials called hybrid perovskites. In just five years of development, hybrid perovskite solar cells have attained power conversion efficiencies that took decades to achieve with the top-performing conventional materials used to generate electricity from sunlight. Now researchers at the University of Utah, in collaboration with the University of Texas at Dallas, have uncovered some of the secrets behind the amazing material’s performance.

Silicon Avalanche Photodiode

Excelitas’ (Waltham, MA) new HeliX Silicon Avalanche Photodiode (APD) Module is a compact, easy-to-use, analogue low-light-level detection (L³D) module employing Excelitas’ Si APD chips. The detector is in a hermetic TO package, mounted on a practical OEM-based PCB that includes high-voltage power supply, temperature compensation, a low-noise transimpedance amplifier, APD bias monitor and micro- controller. The preamplifier gain is optimized to obtain maximum dynamic range and linearity with the APD at gain adjustable operating voltage. It optimises APD operation in key performance parameters such as higher sensitivity, and better signal-to-noise ratio across the 400nm – 1100nm wavelength range.

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.
