Additives to Minimize Dirt Accumulation

Polymeric and non-polymeric additives must release dirt from stucco, decks, and other coated architectural surfaces. A client seeks hydrophobic surfaces that are hard rather than tacky, and offer low surface tension and high contact angle. Preferably, a homeowner could spray these enhanced coatings with water and quickly wash away accumulated dirt. The additives must be compatible with water-based systems such as acrylics and styrene-acrylics or alkyds, as well as with polyurethanes and epoxies. Technology options must also accept occasional re-coating, and resist standard soaps and household cleaners.

Cost-Effective Cholesterol Tests

A client seeks a simple, small, and cost-effective diagnostic cholesterol test kit. The technology must be used directly by a consumer, possibly as an in-home test kit. Results should be visible immediately and show different levels, including normal, moderately elevated, or high cholesterol. Solutions could be minimally or non-invasive diagnostics that detect one or multiple states, and could include tests for blood, breath, saliva, sweat, urine, or tongue scraping. Ideally, tests must be validated against standard blood cholesterol tests, and detect a 10% change in total cholesterol.

Speed2Design: A Chance of a Lifetime

I recently had the chance to spend a day at NASA’s Johnson Space Center in Houston with the ten winners of the Speed2Design contest sponsored by Littelfuse, a Chicago-based circuit protection company. The prize was a behind-the-scenes tour of the center, including technical conversations with the engineers working on robotics and rovers, astronaut training, and International Space Station (ISS) research. Having been to NASA facilities multiple times, I had a “been there, done that” attitude at first, but was quickly as amazed and awed as the winners by the technologies and facilities at NASA Johnson.

Product of the Month: the GEN3i Portable Data Recorder

HBM, Marlborough, MA, has introduced the GEN3i portable data recorder, part of the Genesis High Speed line of data recorders. They are designed for laboratory, power test stands, and destructive material testing applications, as well as for generators, turbines, and engines. The recorder transfers data directly to the storage medium at speeds as high as 200 MB/s (one hundred million measured values per second). A user can employ 18 channels at 2 MS/s, producing 4 MB/s per channel. The 18 channels will produce 72 MB/s continuously until the 480- GB solid-state disk (SSD) is loaded. Users can select from 21 different data acquisition cards. The recorder can be equipped with isolated strain gauge or accelerometer signal conditioners, as well as ultra-high-speed cards offering sampling rates of 100 MS/s, or an isolated 1 kV data acquisition card with ±1000V direct inputs. It features up to 96 fully configurable input channels and an intuitive touchscreen that lets users access all data handling functions.

Industry Roundtable: Analysis & Simulation Software 2013

In our annual poll of executives at leading analysis and simulation software vendors, we found that high-performance computing is changing the way software is written and sold, and that in a competitive economic market, simulation is not just an advantage, but a necessity. In today’s environment of doing more with less, designers and engineers are constantly pressured to increase productivity, especially in small- and medium-sized businesses where a few people perform the tasks of many. As a result, simulation becomes not only a productivity tool, but also a competitive advantage, and as some of our executives put it, a competitive necessity.

Cryogenic Supply System Protects Crews from Hazardous Gases

The Cryogenic Refuge Alternative Supply System (CryoRASS), and a smaller liquid air-filled backpack under development at NASA Kennedy Space Center’s (KSC) Biomedical Lab, have the potential to store more than twice the amount of breathable air than traditional compressed gas systems.
