Analytical Technique for Healthcare and Industrial Applications

Aria Analytics is commercializing a novel analytical technology to characterize liquids for healthcare and industrial applications. As a drop of liquid evaporates on the vibrating quartz sensor, it undergoes distinctive phase changes representing the unique chemical and physical characteristics of the sample. This unique “fingerprint” represents information that is not readily available from any combination of analytical methods currently in use.

Fly-by-Wireless: A Less-Wire and Wireless Revolution for Aerospace Vehicle Architectures

By George Studor, NASA’s Johnson Space Center, Houston, TX Every ounce of weight brought to the lunar surface costs 40 to 60 times that in fuel needed at liftoff from the Earth. Part of that weight penalty is due to wires, but the cost of wires is much more than weight. Wired connectivity drives up the price of design from the beginning: it drives the cost of the many systems and structures; it drives inspection, troubleshooting, maintenance, and upgrade costs; as well as the cost of making system changes. Future vehicles that can reduce the effects and limitations of wires will not be without risk or a lot of work, but the effort has begun.

Microbial-Based Lawn-Care, Pond-Care, and Cleaning Technologies

Proprietary microbial systems use naturally occurring microbes in lieu of chemicals in fertilizers, microbial inoculants, cleaning products, and pond treatments. Products are based on incorporating beneficial micro-organisms with a variety of task-specific organic surfactants, microbial nutrients, fertilizers, cleaning agents, and bio-polymers. The micro-organisms produce enzymes that continue to work even after cleaning, or — in the case of lawn and pond care — continue to make the soil or pond healthier even after fertilizing the plants or inoculating the water.

Intelligent Multi-Sensor Control Systems to Manage Lighting

Technology is needed to generate a change in the ambience of a given space. The technology must interpret a number of sensory changes within a room in order to change other parameters. Of specific interest is software that interprets multi-sensor data and the consequence hardware to control numerous devices to bring about a desired lighting change.

Performance of 1mm² Silicon Photomultipliers

A silicon photomultiplier (SPM) is a new type of semiconductor detector that has the potential to replace the photomultiplier tube (PMT) detector in many applications. In common with a PMT detector, the output of an SPM is an easily detectable current pulse for each detected photon and can be used in both photon counting mode and as an analogue (photocurrent) detector. However, the SPM also has a distinct advantage over PMT detectors. The photon-induced current pulse from a PMT varies greatly from photon to photon, due to the statistics of the PMT multiplication process (excess noise). In contrast, the current pulse from an SPM is identical from photon to photon. This gives the SPM a distinct advantage in photon counting applications as it allows the associated electronics to be greatly simplified. Identical pulses also mean that the SPM can resolve the number of photons in weak optical pulses, so-called photon number resolution. This is critical in a number of applications including linear-optics quantum computing.
