摘要： A method and a device for detection, classification and densimetric quantification of grain-eating insects, of one or several families of insects simultaneously present, in stocks of cereals and the like, which includes detecting insects through noises and sound and/or infrasonic vibrations emitted by the insects. It also includes carrying out the following operations: recording the real noises in the stock, eliminating known spurious noises, detecting on the resulting envelope energy curve windows corresponding to energy peaks and determining therefrom the mean frequency, the spectral width and the global energy, comparing the mean frequency and the width of each of the windows to that of windows with similar known and listed characteristics, so as to operate a taxonomic classification, finally, comparing the mean frequency and the global energy of each of the windows, to those of windows with known and listed characteristics, to operate a densimetric quanitification.

摘要： A method of controlling the fill level of containers involves the reflection of an acoustic signal which is emitted by an acoustic transmitter/receiver device with the device disposed above a single-line flow of containers. In the method, during an data acquisition step, one or more standard containers with a known fill level are brought under the acoustic transmitter/receiver device. After the emission of acoustic signals, the reflection signal(s) corresponding to the opening and the level of the contents in the standard container are detected. During the subsequent steps for controlling containers with an unknown fill level, the deviation(s) in the reflection signals are compared to the stored standard deviation(s), the reflection signals corresponding to the opening and the level of the contents in the container.
