As promised in my blog, I have an update on student loans. There is an online petition to reconstruct the current student loan repayment system. These changes entitled,”The Student Loan Fairness Act (H.R. 1330)” would create a new “10-10” standard for student loan repayment, in which an individual would be required to make ten years […]

Four Steps to Safeguarding Electrical Equipment from Corrosion
When specifying electrical products for harsh environments, choosing the right materials to ensure adequate corrosion-resistance is crucial. In offshore oil and gas operations, equipment is under constant exposure to seawater and salt spray, which are highly corrosive due to the autocatalytic action of sodium chloride and other dissolved chlorides. Corrosive substances such as hydrogen sulfide […]
DAQ Series: Transmit and Receive Information
DAQs work within computer systems. However, in order to make data acquisition work you must transmit and receive signals in order to process the information. There are a wide variety of interfaces used to connect data acquisition hardware to computers such as PCI bus, Ethernet and USB protocols. In addition to interfaces connecting DAQ systems […]
TEGAM Introduces Helicopter Bond Meter
Compact Instrument is configured as a complete kit for bond measurements. The TEGAM Model R1L-BR1 bond meter is a purpose built, rechargeable battery powered portable instrument for ground bond measurements. The R1L-BR1 comes with BCP-10 Kelvin Probes and KAK-1M Kelvin Alligator Klips, all housed within a ruggedized case for protection during transport. It has been […]
Dynamic testing saves energy, time and money
Dynamic testing of performance factors for a Department of Defense (DoD) customer’s helicopter transmissions, primarily in the Apache and Blackhawk classes presented a challenge, which involved an existing bank of over 20 individual test stands. The existing test stands ranged from 20–50 years in age and had been built with single-purpose functionality. The stands suffered […]
Portable Metrology Pushes Race Teams to Creative Engineering
by Cathy Hayat, Hexagon Metrology, Inc. Metrology became an essential part of the build process once NASCAR brought tighter tolerances into play. At the competitive edge of every professional sport, the margins of victory are often tiny differences in energy, efficiency, skill and physical configuration. Over time, this gives rise to elaborate regulations governing competitors’ behavior, […]
DAQ Series: Podcast: miniSystems for Engineering Excellence
In this DAQ Series, we discuss how DAQs are scaled down for educational purposes. National Instruments is dedicated to teaching engineering fundamentals beyond theory and mathematical applications. Its target is to teach students engineering concepts as a whole. The idea of teaching students hands-on, visual applications came from the suggestions of professors and teachers at […]
DAQ Series: Methodology associated with data acquisition
In the previous DAQ series, What is a Data Acquisition (DAQ), and How DAQs Work at a High Level, terminology that is analogous with DAQs was mentioned. To delve further, this series will discuss the some of the methodology associated with data acquisition. Transducers, Sensors, Actuators: As we know, data acquisition begins with a physical […]
Bodkin Design Receives SBIR Funding from NASA
Bodkin Design & Engineering, LLC (BD&E) has been awarded a $125,000 SBIR contract by NASA to develop a surface temperature mapping system for re-entry vehicle heat shields. The unique system will provide unprecedented temperature accuracy during ground tests. Unlike simple thermal imaging, BD&E’s design uses hyperspectral imaging to greatly increase accuracy. BD&E has previously developed […]
DAQ Series: How DAQs work at a high level
As Daniel Carnes (Facebook reader) said, “As more and more data acquisition systems make their way into our lives it is good to know how they work at least at a high level.” Taking a cue from Mr. Carnes, engineers are no longer stereotyped as the person wearing the white coat in a lab. We […]
