  • Chapter 4 – Capacitors
    Starting Electronics, 2011
    Co-Authors: Keith Brindley
    Abstract:

    Publisher Summary This chapter gives information on capacitors, which are made up from two electrically conductive plates, separated from each other by a sandwiched layer of insulating material. Figures are presented that illustrate the circuit symbols of an ordinary and an electrolytic capacitor. In an electrolytic capacitor, the basic capacitor action is derived through the process of electrolysis when the capacitor is connected into a circuit. Capacitance values are measured in a unit called the farad and given the symbol: F, and capacitors have values in fractions of millionth or thousand millionth of a farad. Capacitors are one of the components required for building a circuit and the other components are the resistor and switch. To make connections between the switch and the Breadboard, multi-strand wires can be used and tin the ends that push into the Breadboard. The use of a 22 SWG single-strand tinned copper wire is recommended since it is quite rigid and pushes easily into the Breadboard connectors without breaking up. A figure of the Breadboard Layout of the circuit is given.

  • COST-EFFECTIVE MICROWAVE SENSING OF HIGHWAY ROAD CONDITIONS
    NCHRP-IDEA Program Project Final Report, 1998
    Co-Authors: R F Kubichek, S Yoakum-stover
    Abstract:

    This Innovations Deserving Exploratory Analysis (IDEA) project developed a new method for measuring moisture, snow, and ice accumulation on roads and highways using microwave-sensing techniques. The basic system was designed and built over the summer and fall of 1996. Following laboratory tests, it was installed at an outdoor paved-road location where data were collected during late March through early May 1997. Pattern recognition techniques were applied to identify road conditions based on microwave signatures, and yielded 88-95% correct classifications of snowy, wet, and dry roads, with poorer performance for slush conditions (16-48% correct). Icy road conditions were not prevalent enough to be included in the test. The results are promising, but suggest additional effort to resolve unexplained poor performance for some road conditions. Currently, it is felt that interference and internal reflections in the Breadboard Layout cause much of the observed problems. If so, follow-on operational tests should employ professionally manufactured transceivers using miniaturized strip-line construction. The University of Wyoming will partner with a microwave system design company for this stage of the project.
