Grain quality inspection system

A review of grain quality indicators and measurement methods was conducted in order to assess the feasibility of using remote sensing technology to develop a continuous monitoring system for use during grain transfer operations. Most detection methods were found to be too slow or too expensive to be incorporated into the normal inspection procedure of a grain elevator on a continuous basis. Two indicators, moisture content and broken corn and foreign material, show potential for automation and are of an economic value. A microprocessor based system which utilizes commercially available electronic moisture meter was developed and tested. A method for automating BCFM measurement is described. A complete system description is presented along with performance test results.

Analysis of an impulse noise suppressor for FM demodulators

An FM click noise suppressor was evaluated by means of several experimental tests conducted to verify previous test results. The range and worst case type of operation for the suppressor were also determined. A brief theoretical justification for the existence of FM click noise near threshold conditions is presented. It is concluded that the circuit does perform click suppression, but over a limited range. Suggestions for improvement of the circuit are given.
