Breadboard Configuration Definition
Breadboards (or solderless breadboards) are a learning tool for building circuits. They are used for making temporary circuits and prototyping, and they require absolutely no soldering. Before breadboards, individuals learning to build circuits used the wire-wrap technique. This involved wrapping wires around conductive posts attached to a perfboard or protoboard. Breadboards are also commonly used to test out new parts, such as Integrated circuits (ICs).

Introduction to spatial heterodyne observations of water (SHOW) project and its instrument development, Lin, Y., Shepherd, G., Solheim, B., Shepherd, M., Brown, S., Harlander, J., & Whiteway, J. (2005, May). Introduction to spatial heterodyne observations of water (SHOW) project and its instrument development. In Proc. XIV Int. TOVS Study Conf., 25-31 May 2005, Beijing, China (pp. 835-843). Water is a critically important constituent throughout the stratosphere and mesosphere. The SHOW project will develop a new instrument to measure water vapour from 15km to 85km height, on a global scale, using the unique capabilities provided by Spatial Heterodyne Spectroscopy (SHS). This work builds on Canadian expertise in fabricating solid Michelson interferometers to fill a significant niche in our current capability. The SHS setup the FTS with the mirrors replaced by diffraction gratings at Littrow configuration, wavelength depended Fizeau fringes are recorded by a 320*256 CCD camera without any scanning elements, the high resolution spectral information along one detector dimension can be obtain from Fourier analysis, and the other dimension will provide the spatial information. At a limb view point, a field-widened SHS with half-angle of 6 degrees for water observations at 1364nm is desired, the resolution is 0.02nm within full bandwidth of 2nm, and the resolving power is about 68,000.
Magnetically coupled linear isolator, Hermann, T. M., Black, W. C., & Hui, S. (1997). Magnetically coupled linear isolator. IEEE Transactions on Magnetics, 33(5), 4029-4031. A linear isolation device has been fabricated using giant magnetoresistance (GMR) thin film structures to sense current in a planar coil across a Si/sub 3/N/sub 4/ insulation barrier. NiFe shields are electroplated to improve signal and shield stray field noise. The devices were connected to an external current replicating circuit realized from discrete components. Measured output characteristics include nonlinearity of less than 1%, and withstanding voltages over 2.5 kV.

Breadboard of a Fourier-transform spectrometer for the Radiation Explorer in the Far Infrared atmospheric mission, Palchetti, L., Bianchini, G., Castagnoli, F., Carli, B., Serio, C., Esposito, F., … & Maestri, T. (2005). Breadboard of a Fourier-transform spectrometer for the Radiation Explorer in the Far Infrared atmospheric mission. Applied optics, 44(14), 2870-2878. In preparation for a possible space mission, a breadboard version named REFIR-BB of the Radiation Explorer in the Far Infrared (REFIR) instrument has been built. The REFIR is a Fourier-transform spectrometer with a new optical layout operating in the spectral range 100–1100 cm−1 with a resolution of 0.5 cm−1, a7-s acquisition time, and a signal-to-noise ratio of better than 100. Its mission is the spectral measurement in the far infrared of the Earth’s outgoing emission, with particular attention to the long-wavelength spectral region, which is not covered by either current or planned space missions. This measurement is of great importance for deriving an accurate estimate of the radiation budget in both clear and cloudy conditions. The REFIR-BB permits the trade-off among all instrument parameters to be studied, the optical layout to be tested, and the data-acquisition strategy to be optimized. The breadboard could be used for high-altitude ground-based campaigns or could be flown for test flights on aircraft or balloon stratospheric platforms. The breadboard’s design and the experimental results are described, with particular attention to the acquisition strategy and characterization of the interferometer. Tests were performed both in laboratory conditions and in vacuum. Notwithstanding a loss of efficiency above 700 cm−1 caused by the poor performance of the photolithographic polarizers used as beam splitters, the results demonstrate the feasibility of using the spectrometer for space applications.
ATLID Laser Head Thermal Control-Design and Development of a Two-Phase Heat Transport System for Practical Application, Dunbar, N. W. (1996). ATLID Laser Head Thermal Control-Design and Development of a Two-Phase Heat Transport System for Practical Application (No. 961561). SAE Technical Paper. The ATLID (ATmospheric LIDar) laser head places severe demands on the thermal control system. The heat load of 230W is concentrated in less than 60 cm2, while heat rejection is via radiators of restricted size exposed to a highly varying external thermal environment. Interface temperature is to be regulated to 5 ±1°C, while lateral temperature gradient at the interface is to be held below 0.1°C/cm. The system is to be subjected to qualification level vibration testing, and must meet challenging stiffness and mass requirements. Design and testing of a capillary pumped two-phase heat transport system to meet these requirements is described. The results demonstrate significant margins in thermal performance even under adverse 1-g conditions, and illustrate several interesting two-phase phenomena which are discussed in detail.
Suitcase TOF: a man-portable time-of-flight mass spectrometer, Ecelberger, S. A., Cornish, T. J., Collins, B. F., Lewis, D. L., & Bryden, W. A. (2004). Suitcase TOF: a man-portable time-of-flight mass spectrometer. Johns Hopkins APL technical digest, 25(1), 14-19. The need for man-portable analytical instrumentation to detect and identify potential chemical and biological hazards in the environment is growing as the number of natural and man-made threats increases. To that end, APL has been developing the Suitcase TOF, a small suitcase-sized Time-of-Flight Mass Spectrometer, and testing it extensively on known chemical and biological agents. This article introduces the reader to TOF mass spectrometry, describes the features of the Suitcase TOF that make it portable and rugged, and touches on the results of agent testing. Application areas include fi rst-responder and special operations spot checks, clinical medicine, medical research, infrastructure

Ultra-high pressure down hole pump for jet-assisted drilling, Veenhuizen, S. D., O’Hanlon, T. A., Kelley, D. P., Duda, J. A., & Aslakson, J. K. (1996, January). Ultra-high pressure down hole pump for jet-assisted drilling. In SPE/IADC Drilling Conference. Society of Petroleum Engineers. An ultra-high pressure (UHP-30,000 psi) downhole pump (DHPTM) is being developed for jet-assisted drilling. With this technology, drilling penetration rates in gas and oil wells can be increased 1.5 to 2.5 times. The prototype downhole pump was built for laboratory and field experimentation under a program with the Gas Research Institute. A second generation prototype is being supported by the U.S. Department of Energy – Morgantown. Current development is focused on the DHP system that develops the UHP fluid stream used to assist the drill bit. The pump is located just above the drill bit. Its rated output is 22 gpm at 35,000 psi. The DHP is about the same size as and is handled like a conventional drill collar. Power to drive the DHP is taken from the conventional mud stream. Surface mud pump pressure is elevated approximately 1,500 to 2,000 psi while maintaining conventional flow rates downhole Five field experiments were conducted with the first prototype. Observed ROP ratios varied from 1.1 to about 3.5 times conventional rates. The second prototype is currently being tested in the laboratory.
