    Theoretical studies have shown that the properties of electrically short monopole antennas are improved by placing an inductive load on the structure. The results obtained from the moment method are presented and compared with an experimental evaluation. The current distribution along the structure is computed and measured for various positions of the load. From this, the input admittance, efficie... View full abstract»

    Voltage controlled crystal oscillator (VCXO) frequency modulators have found increasing use in recent years in portable frequency modulation (FM) equipment as an alternative to a standard crystal oscillator followed by a phase modulator. The advantages of using a direct FM VCXO over an indirect FM phase modulator are considered. A model for the crystal and frequency control element will be develop... View full abstract»

    An in-car warning system has been designed which indicates the occurrence of excessive engine misfires by analyzing the ionization signals obtained from each spark plug's center electrode. A prototype model of this design has been built and evaluated on a 2000 cc, 1973 production four-cylinder engine. Reliable operation was achieved from idle to 6000 rpm. The system consists of two basic elements,... View full abstract»

    A receiver-transmitter system at 99 MHz is energized by a shock activated switch to provide warnings of collision, emergency vehicles, or other road hazards. The system was designed and constructed as part of a senior design sequence. It was intended to be simple and reliable, and, when translated into modern integrated circuit technology, it can be installed at a low cost per vehicle. It provides... View full abstract»

    A potentially useful method of reducing pollutants in automobile exhaust gas and reducing fuel consumption is the optimum control method for ignition timing of the mixture. Optimum ignition timing varies with the state of engine operation. Moreover, it is a complex function involving parameters of engine operating state. Ignition timing is usually expressed as the measure of angular displacement o... View full abstract»
