| 摘要 |
<p>The instant invention pertains to ascertaining the condition (i.e. texture, maturity and extent of damage (if any)) of an agricultural commodity (10) by: (a) inputting band-limited vibrations (12, 124) (i.e. limited to a specific frequency band); (b) sensing vibrational characteristics (13, 125) (e.g. energy, resonance, absorption frequency characteristics) resulting from the input vibrations; and (c) analyzing the vibrational characteristics.</p> |
