wireless energy transfer. Some of the then scientists are Hertz: A precursor of this technology can be found in the works of Heinrich Rudolf Hertz in the late nineteenth century. In 1888‚ Hertz experimented with pulsed power transmission at 500 megahertz. Tesla: Tesla was able to light gas discharge lamps‚ he lit ordinary incandescent lamps at full candle-power by currents induced in a local loop consisting of a single wire forming a square of fifty feet each side‚ which includes the lamps‚ and

distortions. Unlike traditional narrowband systems‚ their UWB counterparts operate by employing very short electrical pulses of nanosecond and sub nanosecond duration resulting in very wide transmission bandwidths ranging from several hundred megahertz up to several gigahertz. Such huge bandwidths must be supported with suitable UWB antennas that behave unavoidably as band pass filters. UWB antenna designer may chose among known antenna solutions or create new ones to meet diverse system-related

Battery Desulfator Errata In my battery desulfator article on page 84 of HP77‚ the value for C2 should have been 0.0022 ìF‚ not 0.022 ìF. My mistake. I have put up a Web page that will give more details to help you build and use the desulfator circuit. I will place updates there‚ and will add a guestbook soon to allow comments and questions to be posted. I encourage a group effort in this‚ since I don’t have all the answers. Thanks.

Characteristics of Information • Accurate -Accurate information is error free. In some cases‚ inaccurate information is generated because inaccurate data is fed into the transformation process. (This is commonly called garbage in‚ garbage out [GIGO].) • Reliable -Reliable information can be depended on. In many cases‚ the reliability of the information depends on the reliability of the data-collection method. In other instances‚ reliability depends on the source of the information. A rumour

Chapter 2 – Information Technology and AISs What is AISs (Accounting Information Systems)? It is the application of information technology to accounting systems. It’s a collection of data and processing procedures that creates needed information for its users. What is IT (Information Technology)? It is the hardware and software used in computerized information systems. AIS can be viewed as a set of 5 interacting components: 1) hardware‚ 2) software‚ 3) data‚ 4) people‚ and 5) procedures

ABSTRACT: This is a new technique for the protection of transmission systems by using the global positioning system (GPS) and fault generated transients. In this scheme the relay contains a fault transient detection system together with a communication unit‚ which is connected to the power line through the high voltage coupling capacitors of the CVT. Relays are installed at each bus bar in a transmission network. These detect the fault generated high frequency voltage transient signals and record
